of buckwheats and butterflies

Eriogonum parvifolium (var. parvifolium)
Polygonaceae

edited 11/25/14 -  I've made a public fool of myself.  And, I'm okay with that.  Sharing my journey may help someone else learn something new about themselves, or about the world around them.  Sincere apologies to those who have read through my numerous emotional incarnations of pure drivel as I worked all of this out in a very public space.  I do thank you for your time.

The embarrassing kicker is that my experience could be the perfect demonstration, p-e-r-f-e-c-t, of the perils of ID based on observable traits.  Art Shapiro kindly pointed out to me, "Your essay is no surprise to me. Laypeople often think taxonomy is just naming and identifying distinct entities in Nature (for the religious, add "as created by God"). Well, it ain't. DNA sequencing has underscored that! I've been teaching students since 1972 that "if species weren't messy, we'd have no reason to believe in evolution." Subspecies are even worse. In the heyday of the Neo-Darwinian Synthesis, taxonomic subspecies were viewed as species in statu nascendi. Some folks understood way back then that being recognizable to a taxonomist had no necessary implications regarding genomic differentiation. Now we KNOW that. Do you want me to go on?!"

I read this last night, and it made absolutely no sense to me.  Then, it hit me how I've been understanding all along that Art's got some bugs in his 40+ year transects that look nearly identical, but are not the sameI know this.  He also sent me one of Jim Reveal's old papers about the amazing sequential evolution between butterflies and their host plants...  Oh, my God!  How could I have been so blind?  It's fascinating to look at my own deep-seated beliefs compared to what I think I know intellectually.  They don't match!  It's crazy making.  I was at a point of complete frustration, and I'm glad Art spoke up in such a direct way.  Maybe other people have been telling me all along, and I just haven't been listening?

I can't believe I never saw this before, because I'm fairly self-reflective.  I've always considered myself firmly in the evolution camp ever since my junior year of high school (1987-1988), and a handful of us asked our Mormon AP biology teacher for his opinions of evolution vs. creationism (now disguised as intelligent design), which had been the topic of a recent US Supreme Court ruling (Edwards v. Aguillard).  To be honest, I hadn't given this much thought since then, even though my college degree is in the sciences.  You'd think I'd know better.  However, I was raised in a conservative Christian family (the 700 Club, laying of hands, speaking in tongues, no drinking alcohol, no secular music in the house, no reading LOTR, etc.).  I'm definitely not that way today, but it's funny how the cultural beliefs of the people I've been around have seeped into my subconscious.  It's ironic for a blog titled Nature ID, as in identification, not intelligent design.  Have I been subtextually promoting intelligent design?  This was never my intention.  I need to reevaluate.

Art sent me a follow-up e-mail that explains things pretty well for me.  I've edited it for brevity. He says, "...we have learned in the era of "barcoding" (if you're unfamiliar with it, search the term) that the number of apparent genetic species is often larger than the number of taxonomic species, because cryptic or "sibling" species are often concealed by one phenotype. That is, the phenotype has been constant while the genome overall has changed a LOT. Surprise! Here's a bird example--a bird!  ...The whole thing started with butterflies, but it has now expanded to everything (my naming usage follows the genetics for herps). On the other hand, taxonomic subspecies may be dramatically different in phenotype, but virtually identical genomically, because those conspicuous differences are caused by just a few genes under strong selection, superimposed on a constant genetic background..."  Wow.  Just wow.  My mind is blown as to how I knew about this, yet haven't actually applied it to my hobby cum citizen science project turned hopeful serious science project that can be peer-reviewed and funded.

So, does anyone know who is currently doing the DNA on buckwheats in CA?  Is this buckwheat genetically different than the one Smith's needs, even though its superficial physical characteristics match what's found right along the coast?  I'm still curious to see if the buckwheat(s) that Smith's actually uses (or can use in situ, with potential drawbacks) is the one that's being planted for mitigation as it's currently practiced.  I owe the two CNPS authors an apology for making such a fuss (but not for pointing out their error - I wish I could be more diplomatic).  I'll have to ask around if anyone has already tested this idea, because I'm not sure the authors know themselves.  Otherwise, wouldn't they have just pointed that out, instead of hanging their hat on the amount of hairiness?  Does anyone know?

With this kind of potential discrepancy, how can we use physical features and observations in the field and for what purpose?  How do we separate what we see with what we know is continually changing and evolving?  How do we assign names to each defined entity for the sole purpose of clear communication?  Have we lost the original definitions and intent of common names vs. scientific names in the age of digital photographs, online sharing, and public outreach in the form of organized counts and BioBlitzs?  Are field guides (and all their online incarnations) really just a 1950's era hobby that have little to no basis in science as we understand it today?  Do they keep the layperson lay?  Eh, maybe some of these questions are too much of an exaggeration, but is there truth in there as well?

As humans, I think we have an instinctive need to identify things, although our ability to do so is not always intuitive.  What are you?  It's in our nature.  Maybe I want to stay lay, because I've been having so much fun tacking on names to everything?  It's like a game.  Heavy, heavy sigh. I'm going to leave my post below as I had last edited it (including the incidental original religious references and the late ps) as a true testament to the perils of ID from a layperson who got led astray by her own righteous beliefs as she tried to find her way back to science on her own.  Ha!

Seacliff buckwheat was my very first buckwheat ID on Nature ID.  I've come a long way since then in learning about the local nature.  As you know, I rely on photographs rather than keys for most of my IDs.  I believe my process and methodologies have served me well in the 5 1/2 years I've been doing this blog, specifically designed to be my personal learning tool.  I've been able to quickly recognize seacliff buckwheat ever since this spring with my numerous casual trips down the coast, looking to learn the local buckwheats and butterflies.  It's a common native plant around here.  And, it has caused me more headache than you can possibly imagine. 

To me, this shrub's leaves have a distinctive cobwebbiness to the topside (adaxial - with a 'd', as in dorsal) that can sometimes look like it's been partially rubbed off to a shoeshine, and underneath (abaxial - with a 'b', as in belly) there's a thick cottony felting that can sometimes be so thick it extends down the woody stem.  It just has a look that is much easier to recognize than it is to describe in words.  Granted, there are at least two forms I recognize around here, this one shown here with the narrow-arrow leaves (Mortuary Beach) and another one with really fat/wide round leaves mainly from online photos and a vague recollection of having seen it adjacent to the ocean (Point Lobos, Asilomar, gardens?).  If I were to assign a common name to each form, this narrow-arrow one I would call seacliff buckwheat (I find it really does grow on steep hillsides that have any hint of marine influence, i.e. right up from the water to extending inland at least 12 miles or more), and the round one I would call dune buckwheat.  Neither shrub form should be confused with the similarly-and-confusingly-named perennial herb coast buckwheat, aka seaside buckwheat (E. latifolium), a common mistake that I've noticed online. This is all fine and good that I can recognize these by sight.  However...

Through a series of communications for my research permit application as required as part of my agreement with my Monterey Co. butterfly site (not Garland Ranch), it's come to my attention that the local CNPS folks believe this is CA buckwheat (Eriogonum fasciculatum) and more specifically, var. foliolosum.  Nope.  I went back and checked their local field guide, their CNPS-endorsed website, and a draft that was sent to me of the Monterey Co. wildflower bible revision that one of them is updating.  They are correct in recognizing the rounder form as dune, which is fine.  But, I can clearly see they have the mistaken impression this narrow-arrow form of seacliff buckwheat (E. parvifolium) is CA buckwheat (E. fasiculatum), two different species.

In my experience, that multi-toned pink, tight pom-pom shape they show in their "CA buckwheat" photos is distinctive of the mature summer season's seacliff buckwheat, and I have never seen that flower head on CA buckwheat, which tends to be looser in shape (ex. of comparable summer season CA buckwheat).  I asked around and have been informed by people who have grown buckwheats for decades that these two species do not hybridize.  I specifically went to Terrace Trail at Garland Ranch's Garzas Creek access on 11/17/14 just to take these diagnostic photos (see also at the bottom of this post), because this is the location I was told by one of the CNPS authors where he's found CA buckwheat.   I was fully prepared to find CA buckwheat (and actually hoping!), but I didn't.  I found this narrow-arrow seacliff buckwheat, instead.

The Garland Ranch wildflower field guide has been very useful to me as I learn the local plants.  I make no qualms that it's well-designed and one of the best ones available for our area.  I would recommend it to anyone interested in local wildflowers.  With that said, I do think the authors' mistake makes it impossible for anyone to ID the local buckwheats by using their guides.  What I've seen of the wildflower bible revision draft, which is a CNPS publication, is misleading and could be improved.  I hope they get that fixed, but not likely.  I tried my best to explain and provide evidence as to why I think their ID isn't right, but they maintain they're correct in calling it "CA buckwheat".

Here's the thing, I have been staring at real CA buckwheat at Pinnacles every single week going on 8 months now and looking at thousands of my own pictures and others' online of CA buckwheat from all over the place.  While I still may not always be able to distinguish Pinnacles' var. foliolosum (the local CNPS ID, btw) against var. polifolium, I know CA buckwheat (Eriogonum fasciculatum) to species, in person and in photographs, through the seasons.

I've also consulted with photo-documentarians for the Eriogonum Society, the National Park Service, and CalPhotos.  Even if they're unfamiliar with seacliff, they have confirmed it is not likely CA buckwheat, which is more common and familiar in SoCal.  I've been utterly amazed at how many people don't actually know how to distinguish buckwheats (or are not willing to say on record). Hey, I don't know all of them either, but a handful of the larger local buckwheats are really obvious to me now that I made it my mission to learn the local buckwheats this year.

Given the continuing disagreement over this ID, I had to seriously consider the possibility that the local CNPS authors could be correct in their determination, especially considering one is revising the local wildflower bible and many people defer to their opinions, including the folks at my Monterey Co. butterfly site.  Their insistence made me question my own observations, because I know I make mistakes, too.  For my own peace of mind, I needed to double-check what I felt I already intuitively knew, so I took the time to research the keys and figure out the dizzying array of taxonomic terms.

Basically, it boils down to leaf shape.  Simple as that.  When keying to species (not variety) between the two, forget what you hear about amount of fasciculation or hairiness/tomentoseness (remember, hard to describe in words).  The Jepson eFlora keys out E. fasciculatum at 60/60' with "Leaf blades narrowly linear to oblanceolate".  Additionally, eFloras of North America keys out similarly at 20/+ with an additional statement under the species description for E. parvifolium, "blade lanceolate to round".  Linear and round are pretty obvious, and the above is neither.  Now, google images or take a look at this exaggerated graphic between lanceolate and oblanceolate.  The leaf shown above is clearly lanceolate (aka narrow-arrow), therefore E. parvifolium.

I also reached out to Jim Reveal, the author of Eriogonum.  For additional reference, here are his original descriptions, from which I believe most every key depends for EriogonumE. fasciculatum and E. parvifolium E. parvifolium has not been keyed out into varieties, and Jim told me he doesn't officially recognize them.  With that said, there were certain forms or phases he did recognize in the past, until he was shown examples that completely graded with each other.  For my own edification, here's how I understand it: var. parvifolium ("thickened leaf blades" and "compact clusters of involucres containing white to rose flowers", this is the narrow-arrow form I find common around here in the wild), var. crassifolium ("compact and dense mat-forming", is this a round one found in the sand? I don't know), var. lucidum ("yellow flowers" with round leaves, also found here with a white phase, too, according to Jim), and var. paynei ("white-flowered inflorescences", and "more graceful habit", found down in Ventura Co. and is supposed to be large).  I'm guessing this elegant white phase shown here on Terrace Trail at Garland Ranch may just be how "var. parvifolium" grows in protected, shadier places, because it has the same leaf shape as the shrubbier pinker one I find on exposed sunny hillsides that Jim confirmed the ID for me via my photos.  Again, seacliff buckwheat varieties are not formally recognized.

So, why is this plant such a big, huge, deal for me to go to all this trouble?  

Six words: the federally endangered Smith's blue butterfly.  The seacliff buckwheat (Eriogonum parvifolium) is its host plant.  There is only one person in the entire country who has ever been granted a permit to study this butterfly and in essence even be around seacliff buckwheat for research purposes (I may be exaggerating slightly, but you get the picture).  While I'm sure he's done a lot of good, he's also made quite a tidy business over his legally-mandated monopoly.

The fact of the matter is, there are very few people who could see a blue butterfly and know it is or is not Smith's.  I believe I could eventually tell, only if I could be allowed to get close enough and take enough photographs as absolute substitutes for physical specimens.  It's worked for me with buckwheats, why can't it work for me for butterflies?  Gotta start somewhere for baseline info.  Let someone else do a specific collection to work out the genitalia and genetics if anything unusual is seen.  I've heard that merely taking photographs of this endangered butterfly can be considered as "take" by the USFWS, a strict no-no.  Sigh.  It sure seems silly that the very laws created to protect an animal keep us from learning more about it.  Something is seriously broken in the system.

Hey, I'm not even particularly interested in Smith's, but I discovered seacliff buckwheat is the dominant native nectar source for butterflies at my Monterey Co. site (again, not Garland Ranch).  I can't study the other butterflies without getting near Smith's listed host plant, and if they are there, either in flight or potentially trampling over delicate pupae around the buckwheat bushes.  I wonder if we might even have one of the square-spotted blues (Euphilotes battoides) in the area, which isn't reported for anywhere near here, but that may be because no one admits to looking close enough over fear of Smith's restrictions.  They do look a lot alike.  The selfish solution for me is to see Smith's delisted, but it's all entangled with political and financial motives. 

The federal permitting process for Smith's is essentially non-existent and shrouded with stories of how impossible it is to jump through the hoops to meet their requirements.  They require experience to get the permit, but no one can get the experience without the permit or threat of jail and financial ruin.  Catch 22.  From several people, I've heard hushed horror stories about closet lepidopterists who live in fear and flatly refuse to cooperate with other researchers over concerns of being raided by federal agents.  I have no way of knowing if any of these stories are actually true.

These stories not only hamper research to learn more about this rare butterfly, they may also hamper the information made available about its host plant.  I figure there must be some antiquated law about not being able to update listings based on new findings.  Gordon Pratt believes the listed species (Euphilotes enoptes smithi) is not the one that's actually rare, but he told me he was talked out of delisting by the USFWS.  Smith's close relative (Euphilotes enoptes arenacola), which he helped describe, that feeds on coast buckwheat (E. latifolium) in a small sandy area in Marina is the one that he believes is truly endangered, and Smith's law protects it, too.  Likewise, I wonder if there was pressure on Jim Reveal to not reveal (pun!) his buckwheat variety designations, because it would further complicate the listed identity of several endangered butterfly host plants.  I asked him directly, but his answer shed little light on the question.  The reason why I came to this conclusion is because Jim goes into such mind-boggling detail for the various buckwheats and their varieties (case in point, sulphur buckwheat/E. umbellatum has 45 keyed varieties as of 2002), and yet for the seaclifff (E. parvifolium) and coast (E. latifolium), nothing, nada.  They are as they are, no variety designations, even though there's obviously different forms.  You'll notice that both of these buckwheats are host plants for endangered butterflies (real or listed).  Or, maybe even he can't get a research permit to study the plants that the endangered butterflies need?  I don't know, but there's gotta be more to the story.  I believe this lack of variety designations for seacliff, when there are so many for other buckwheats, confuses a lot of good plant people who may only be familiar with the round dune version. 

So, maybe Smith's blue is a common butterfly around here, who's to truly say?  Without hardly trying, I have twice found the earliest seasonal record for Smith's blue, once in 2003 and again this year 2014, the only two years I've gone down the coast with the specific purpose to look for various butterflies (hey, I've been busy pursuing other interests in the intervening 10 years).  I personally suspect Smith's is way more common than anyone realizes considering the locally recognized "CA buckwheat" is actually seacliff buckwheat.  Maybe people haven't been looking in the right places for the butterfly?  In any case, I imagine there might be some wealthy landowners out there who were relieved to find out they had "CA buckwheat" and not seacliff buckwheat on their property when it came time to do their EIRs before they developed.  Eh-hem.

On the flip side, I have a hunch CA buckwheat (E. fasciculatum) in Monterey Co. is not as common as is reported by the local CNPS chapter, unless it's found along the highway where it's been planted by Caltrans and maybe further south towards SLO.  eFloras also cautions that var. foliolosum is, "a potentially aggressive weedy shrub, efforts should be made to curtail its introduction into areas outside its native range."  I worry that good-intentioned native gardeners, seeing it listed as occurring here, will plant the not-native to this area weedy CA buckwheat, where it could easily escape and compete with the locally native seacliff buckwheat.

Most importantly, the narrow-arrow form that is mistaken in our local books for "CA buckwheat" is, in fact, the seacliff buckwheat form that I have personally seen Smith's blue on and is in all the photographs I can find online where the butterfly is actually on the plant.  Yet, when E. parvifolium is shown without the butterfly for illustrative purposes of the reported host plant, the round shape is chosen to be used.  Peculiar and possibly misleading.  I'm thinking that's because the round dune form is the one people first think of for E. parvifolium, very likely due to the famous El Segundo blue's round dune use down south, which had a spectacular CA buckwheat fail.  I worry folks are planting the round dune up here as part of mitigation based on the El Segundo experience, when really the narrow-arrow is what Smith's uses.  And, that's not to imply all narrow-arrows are used by Smith's. So, if anyone needed to do restoration or mitigation work as required by law, they'd be pulling out the narrow-arrow seacliff buckwheat fully believing it's the weedy "CA buckwheat" and planting the round dune form, which could possibly be the wrong seacliff buckwheat form for Smith's.  I'll admit, I don't actually know if this happens here with Smith's, but who does?  

It would have worked in my favor if this really had been CA buckwheat.  Despite my desire to be correct, I was actually hoping I was wrong, because then I'd have no need to apply for a federal permit for my butterfly site.  Problem solved.  But, I'm not okay continuing to call it "CA buckwheat" just because other people say so.  That's just bad research.  If I had only kept quiet, I might have been able to make nice-nice with the local CNPS folks.  Although, at this point, with the way they dismissed all my research and documentation, I don't feel they have earned, nor deserved, my trust.  I'll admit, I made a bit of a fuss as I was attempting to get them to see reason.  I can be very pushy in getting things correct, and it does not do me any favors in winning over people.  I've pretty much burned that bridge.  Erm... torched?  

Such as it is, imagine for a minute, the ripple effect this simple ID error has... 

Their expert plant advice (books, online, in person) is probably followed by many environmental consultants who do EIRs and restoration-type work (if you believe they know better, I have a burnt bridge to sell you), who then also mistake this buckwheat ID, which ends up determining the fate of the land all based on a plant name, potentially costing millions of dollars (or making others billions of dollars), and all to the detriment of the very butterfly we're trying to save from extinction.   

This is important!  Does any of this make any sense to anyone besides me?

I sincerely thought I was helping by pointing out a simple correction, like I do all the time when I look up stuff for Nature ID (most people are appreciative).  However, it does beg the question why these old guys, who are no more botanists than I am (they're two fellows with a lot of money who moved here from far away places for retirement), are so adamant that I'm wrong with barely an explanation.  This is not a fight I'm up for.  I wish I could continue with my butterfly studies at my Monterey Co. butterfly site, even if I avoided the seacliff buckwheat like the plague and went searching the brambles for Nymphalids (don't think I haven't thought of this), unfortunately, by doing so, I would not be able to honor the spirit and intent of my private land access agreement. 

As it is, I may have to completely abandon my grand plan to have a companion Monterey Co. butterfly research site in conjunction with my Pinnacles one in San Benito Co., two sites on roughly the same latitude and with similar elevation changes, with similar historical and current cattle land usage, with two native butterfly-pleasing shrubby buckwheats, one cool coastal and one hot, hot, hot, to monitor as the climate changes for the next 20+ years, the rest of my life. Wouldn't that be an incredible data set!?!  

Unfortunately, I'm facing the reality that I will not likely be granted a federal permit anytime soon.  Even if I did manage to get one by some miracle, I would still have to fight the local transplants.  Quite frankly, I feel utterly defeated over this issue and how complicated it got rather quickly.  This has significant personal implications for me, far beyond a simple plant ID or a couple rare butterflies. Have I been overly dramatic?  Sure.  Sob.  At the very least, this hullabaloo has made me rethink my plans and scale down, way down.

Terrace Trail - Garland Ranch - Garzas Creek

Again, I specifically went to Terrace Trail, because this is the location I was told by one of the CNPS authors where he's found CA buckwheat for his field guide.  This is the only type of buckwheat I found on the hillside.  Eh, there might have been an herbaceous buckwheat tucked in there, but remember, I went looking for shrubs.

The photographs below were taken as part of my ongoing effort to better document plants without the need to clip a specimen, bag it, press it, store it for perpetuity who knows where. And, at the point we're taking photographs of dried, dead specimens, wouldn't photos of the living work just as well, or even better?  I feel the same about butterflies, too, and had hoped my method could have been a possible avenue to get federal permit approval.  With the quality of macro-photography these days, I think we need to evolve past collecting things to be hidden away in closets (or for those wary of dermestids and moth balls, in freezers).  Plus, photos are so much easier to share and get feedback.

it's November, so the flower selection is sparse

Does anyone know the name of the stringy brown nest-looking stuff found at the base of the bundled perianths on older buckwheat flower heads (last photo here)?

variety of leaf shapes, from roundish to narrow-arrow to superficially linear 
(must look at individual leaf to really make that determination)

contrary to what the local bible says, I believe seacliff is often fasciculate

one last look at overall form and appearance
(note V-shaped cyme with flower clusters half-way up)

ps - For the evolutionary biologists out there who have a valid criticism that I'm focusing too much on names (man-made construct), when speciation (natural) is in constant flux, I'll concede this post does read like that.  Funnily enough, the names are in flux, too.  Like I've said before, I don't really have the writing skill or vocabulary to describe what I'm seeing, hence, why my photos have served me well. For once on Nature ID, the point of this post is decidedly not about the names in of themselves. Rather, it's precisely because of the confusion over those names that the issue described here becomes real in practical application.

To put it another way, it may be best to substitute species names and varieties (and all the baggage that entails) and simply label each entity as a snapshot in time.  BugX feeds on PlantA.  BugX does not feed on PlantB, nor on PlantC.  Human1 groups PlantA and PlantB together and calls it Plant AB.  Human2 sees PlantB, and calls it PlantAB.  Human2 also sees plant A, does not know Human1 includes it in PlantAB, and then calls it PlantC, for lack of a better alternative.  Human3 wants to save BugX.  Human3 reads that BugX feeds on PlantAB and to remove competing PlantC.  Human3 uses Human2's labels.  Human3 plants more H2's PlantAB (PlantB) and removes H2's plantC (PlantA).  PlantB and PlantC thrive.  BugX no longer has PlantA to feed on.  BugX is not saved.

Does this help explain?  As a repeat reference that helped get me thinking along these lines:

autumn thoughts

September 22, 2013

I feel like autumn arrived 3 weeks early this year.  Does anyone else feel like that, too?  I can't really put my finger on why.  Maybe it was the sound of the waves crashing earlier than I expected?  Or maybe it was my first seasonal sighting of a Townsend's warbler on 09/15/13, a whole month earlier than I've seen them previously (Roberson states wintering extremes run from early September to mid-April)?  Or maybe my strong yearning to see autumn rain is so much so that I'm hoping the late summer dry season could just hurry up and be over?  I'm getting impatient.  The sweet half hour of rain on Saturday was not enough to quench my thirst.

In any case, early Sunday morning while sipping coffee, Andy and I groggily discussed where we wanted to go for a hike.  Elkhorn Slough got tossed out, because it just didn't capture our fleeting interest - although it'd probably be fabulous for migrating birds starting about now.  I tend to avoid extremely dry and dusty Fort Ord this time of year, too.  Andy has been running enough at Jacks Peak lately that he didn't want to head there.  I suggested Mt. Madonna, because I figured the shady hills could provide us relief from the 70+°F heat predicted for the day.  Andy disagreed and thought it'd be blazing hot on the inland side of the mountain.  So, we settled on Garzas Creek with the promise of Jefferey's for breakfast.  I'm a little impressed and a little disturbed that we can rattle off various local places to hike and take a pick depending on the season and our finicky desires.

Our first observation when we got out of the car was how the oaks had a healthy crown of leaves, in stark contrast to the bare stripped branches we saw the last time we visited 10/14/12.  There were no oak moths to be found today.  I was expecting this to happen based on what I've read about oak moths.  Does anyone knows why oak moth populations crash after a couple years?

I have to say, I'm in awe with how much Garzas Creek blatantly changes through the seasons and from year to year.  Here on the coast with evergreen oaks and conifers bathed in moderate year-round temperatures, seasons are not always quite so obvious as it is at Garzas.  I've linked to past posts for photo comparisons below. 


(compare to second photo 11/19/11)

I'm starting to prefer the little redwood groves we have down here compared to the big monotonous forests starting around Santa Cruz going north.  I like the variety interspersed with oak/bay and maple/sycamore areas.  This trail is absolutely gorgeous when the leaves change colors and drop.


(compare to third photo 11/11/10)

It's difficult to tell for sure, but I think there's even less water this year than last year.  They take the footbridges out mid-November, which makes me wonder about the seasonal timing of the Creek. Does it always dry out, except for small pools of standing water here and there?  And, what's the typical timing?  How many rains before it starts running again?


(compare to first photo 07/14/11)

I was actually surprised to see all the dried buckeye leaves.  When everything is green the proliferation of buckeye trees is not as obvious.  I never really noticed them here before.  We usually hike here a little later than this in October or November, so the leaves would have already dropped.  I heard somewhere that buckeyes drop their leaves based on water (summer deciduous) and not light (autumn deciduous), like many other trees.  Is that true?


(compare to third photo 10/14/12)

Again, notice how the oaks are all intact and not ravaged by oak moths?  Looking back through these photos, I'm struck by how green it was.  Now, if it weren't for the dogs that jump all over you ("should be under owner control" - Ha!), Garzas could easily be my new favorite place to hike.

fence lizard ~ 09/22/13 ~ Garland Ranch

Sceloporus occidentalis bocourtii

We've had the Konica Minolta DiMAGE X50 for 9 years now, and we just discovered a new automated macro feature.  Yep.  The more we look for a new camera, the more we like the one we already have.  

Once again, I was surprised to find juvenile fence lizards this time of year.  I don't know why it's still a surprise when I've seen them at Fort Ord in August a couple times before.  When do they hatch and how big are they?

And, yes, for some reason I cannot resist picking up little lizards.

habitat ~ 10/14/12 ~ Garland Ranch - Garzas Creek

October 14, 2012

After seeing the gorgeous color change of the bigleaf maples up at Memorial Park a couple days earlier, I wanted to check how the seasonal progression was doing closer to home.  We heard there was only a sprinkling of rain here from the thunderstorm that passed through. Garzas Creek is the one place I particularly associate with native autumn colors from bigleaf maples and CA sycamores. It's 12 miles inland and often has 10-20 °F temperature extremes than at home on the Bay.  It was a bit chilly when we started our hike, and then it got uncomfortably toasty by lunchtime.  What surprised us initially was seeing all the evergreen oaks had been completely, and I mean completely, defoliated by CA oak moths.  It was eerie walking through a coastal CA oak forest with only grey bare branches, twigs, and dried grasses.  If it weren't so warm, I would have thought I was somewhere in February after a winter of regular freezing and snow.  The redwoods and CA bay trees were very easy to spot in the distance.  While the maples had pretty much lost all of their leaves, the sycamores were still quite green.  I wonder if there are different mechanisms for color change and leaf fall between the two tree spp.  Even though the foot bridges won't be taken out for another 2-3 weeks, they weren't necessary. Garzas Creek was bone dry in most places and only had a couple standing pools of water in others. The whole landscape felt very dry and somewhat flat of color to me.  Compare these pictures with those we took November 19, 2011 and November 11, 2010.  If we have more rain in the next 4-5 weeks, I wonder if the ferns and moss will show themselves.  What's unusual about our area is that winter usually signals a time of new green growth.  October is definitely a time of transition.

habitat ~ 01/16/12 ~ Garland Ranch - Garzas Creek

Garland Ranch Regional Park - Garzas Creek
January 16, 2012

posted 01/19/12 - I never thought I'd say this, but I need lots of rain to help pull me out of this year's winter doldrums. Sure, just about everyone else in the Northern Hemisphere would think this sunny warm weather we've had here on the CA coast is a blessing, but I'm feeling parched. Hopefully, we'll get some rain by this afternoon.

This was the biggest hill I've hiked in quite a while, and I'm still feeling some soreness in my thigh muscles. I'm fascinated that the slippery downhill was somehow more difficult than going uphill. I don't have many specific pictures to post, because the hike was its own reward for a change. I wanted to see Veeder Pond, which truthfully is actually a vernal pool. Compare how dry it is now to only 3 1/2 months ago on October 1, 2011. There's a fire tower on the highest hill in the first picture, and there's the Carmel Valley Village airstrip in the second picture, which was utilized as temporary housing for firefighters during the 2008 month-long Basin Complex Fire. In 2008 there were hundreds of fires across CA. I really hope we're not looking at another intense fire year for 2012. Most notable from our hike was an owl we saw fly right by us near the vernal pool. I also noticed dropped leaves on the ground from silver bush lupine, which I believe may be due to the lack of rain, and yellow blooms on CA bay.

habitat ~ 11/19/11 ~ Garland Ranch - Garzas Creek


Happy Thanksgiving! Garzas Creek is going to become my must-do pre-Thanksgiving hike. It's one of the only places around Monterey that has large, native, crunchy, deciduous leaves to tromp through and feels almost like the autumn most people expect in North America. The area along the creek is absolutely gorgeous!

Andy is training for a 50K trail run, so he sped off while I casually took a short loop. We planned to meet up at our favorite restaurant Jeffrey's at Carmel Mid-Valley for lunch. Thanks to a couple of hikers with a dog that liked to jump on me (I had muddy footprints all over me!), I veered off to the redwood trail to avoid them. I worried I wouldn't get back in time to meet Andy, but I am so glad I took this new-to-me trail. The trail loops back to the creek for some of the most scenic spots.

As the sign says, the seasonal foot bridges were taken out the Monday before my hike. I asked a fellow if the creek was passable. He was confident that it could be crossed at the 4 intersections along the trail. Note to self: do not take the advice of a 6 foot tall man with walking sticks if a creek is passable. While I love rock hopping, it helps if you don't have muddy shoes and aren't needing to pass over wet rocks. I managed just fine once I found a couple large sticks to help me balance. After my very grouchy previous week, this hike really helped cheer me up. It was food for the soul, and I am thankful for places like this.

snowberry ~ 11/19/11 ~ Garland Ranch

common snowberry
Symphoricarpos albus var. laevigatus
Caprifoliaceae

I have yet to notice the pretty pink flowers of the snowberry. However, the bright white, small marshmallow-looking berries are so easy to spot, especially when most of the leaves have dropped. The other species of snowberry at Garland is the creeping snowberry (Symphoricarpos mollis), which according to the USDA is only native to CA and NV. To me they look nearly identical in photos, except for the obvious difference, one is erect and the other creeps along the ground. I'll try to keep a look-out next year for the flowers, which, if my books are correct, should bloom in the spring.

CA bay ~ 11/19/11 ~ Garland Ranch


After a full year of thinking about it and posting about it back in July, I finally had my first taste of a California bay nut. Well, actually, being the piglet I am and wanting to compare, I tried 3 bay nuts. I was so excited I didn't get a picture of the first one, but it was reddish and squishy like the first photo above. The flesh had the texture and taste that reminded me of a cross between a firm avocado and an unripe mango, mild, slightly sweet, and with only a hint of bay. The second one I tried was a bit greener yet also soft. I barely nibbled it before I spat it out. It had a very, very strong bay flavor. It left a burning tingle in the back of my throat, similar to the effect I get when I eat fresh mangoes - I've already looked it up, CA bays are related to avocados but not mangoes. Hoping to try another ripe bay nut, I ate a third that was somewhere in between. Had I been prudent, I would have simply saved them and waited until I got home to taste them; for the rest of my hike, my throat tingled and every exhale tasted like bay. My stomach was not a happy camper by the time I finished my hike.

Interesting to note the seed of the first ripe one was very dark, whereas the seed of the second green one was a much lighter color. In the third photo I also want to show there are buds on the evergreen CA bay already. And the last picture shows a very large and mature CA bay tree.

ps 02/06/12 - I initially posted the last picture believing the large tree was an oak (Quercus sp.) next to a smaller CA bay. The significance of this is that the CA bay serves as a host to a pathogen that causes Sudden Oak Death, which also affects tanbark oaks (Notholithocarpus densiflorus). For a very informative blog post about SOD, check out Randy at Way Points. I'm always amazed at the things I learn from fellow bloggers. During another hike at Garzas Creek on 01/16/12, I took a second look at the large tree and realized I had been mistaken about its ID. I've still got a lot to learn about trees.

bigleaf maple and CA sycamore ~ 11/19/11 ~ Garland Ranch

bigleaf maple (left) and California sycamore (right)

Both these deciduous trees are native to California and provide lovely autumn colors. They can be quite tall, so it's difficult to compare the shapes of the leaves when they're too high to examine. It's taken me until this hike, when the forest floor is littered, to truly distinguish the leaves. For the longest time, I thought Garland only had one native large-leaved tree, that being the bigleaf maple. I was wrong. Considering the place used to be a ranch, I figured any sycamores I found were non-native. I've corrected past posts to reflect my new understanding, like last November's Garzas Creek habitat post.


bigleaf maple
Acer macrophyllum
Sapindaceae (formerly Aceraceae)

Notice the 5 deep lobes of the leaf? The vertically grooved bark, often covered in moss or lichen, reminds me very much of walnut trees. Other eastern North American counterparts are red maple (Acer rubrum), silver maple (Acer saccharinum), and sugar maple (Acer saccharum). Despite what the USDA PLANTS database shows, the silver maple is not native to CA.


western sycamore / California sycamore
Platanus racemosa
Platanaceae

What originally confused me about the leaves is the CA sycamore's can have 3 or 5 lobes. I can usually recognize sycamore bark by its sickly, puzzle-like look - yep, that's my own highly technical description. Its eastern North American counterpart is American sycamore (Platanus occidentalis).


bigleaf maple

In a previous post from this summer, I showed how big the CA sycamore leaves get, which can be considerably larger than the bigleaf maple. Happy fall!

ps 11/29/11 - I'm glad I don't have to deal with the differences between sycamore maples and field maples like they do over in the UK, The Squirrelbasket and Loose and Leafy.

habitat ~ 10/01/11 ~ Garland Ranch Regional Park

Garland Ranch Regional Park
October 1, 2011

posted 10/08/11 - Like I said before, I was not out this day. Andy took all these pictures. He likes setting the timer on the camera and shooting himself running down a trail. It seems quirky to me, but I've seen many trail runners do this kind of thing. Park staff and/or volunteers set up several seasonal footbridges across Carmel River and Las Garzas Creek. The one shown is over the Carmel River by Carmel Valley Village, 12 miles inland from Hwy 1. There's not much water and it's not primarily due to the time of year. There's a huge ruckus between Cal-Am (local water co.) and steelhead conservationists. The mountain ranges in the fourth picture above are the Sierra de Salinas range on the left and the better known Santa Lucia Range on the right. The last picture is of Veeder Pond, which despite its name is actually a vernal pool.

As I was writing this post, I realized I haven't labeled many water features, except for vernal pools and waterfalls. I've added some more this morning:
bays (not Monterey)
creeks/rivers
dams/reservoirs
estuaries/sloughs
lakes
Monterey Bay
Pacific Ocean
ponds
snow
Mostly these are scenery shots.

I did a little research to figure out the differences between lakes, ponds, and reservoirs. I also tried to find exactly where the Monterey Bay extends (see District 17). Erga. I didn't like what I found, so I've made up my own definitions. Hey, it's my blog. I don't know the official difference between creeks and rivers and suspect many are misnomers, so I'm combining them for simplicity. Dams and reservoirs are obviously man-made. Lakes and ponds are (or were) natural for my own definition. For the demarcation of Monterey Bay, I've chosen Point Pinos Lighthouse near Crespi Pond as the southern boundary. Since I live here, it's really easy to see the difference in the way the water acts around that point. For the northern boundary of the Monterey Bay, I arbitrarily decided Lighthouse Field State Beach in Santa Cruz, which makes nearby Wilder Ranch State Park part of my Pacific Ocean designation. I really want to get a map up and running for this blog, but I'm still working on revamping my labels. Beside, if anyone were really interested, they could easily google map or mapquest any of the locations featured on Nature ID.
