I wouldn't mind food preparation in this setting

Yesterday I visited the site of a very cool oak restoration project near Springville, CA - a project in which I'm privileged to be playing a small role, supplying tree tubes to protect the newly planted acorns from getting eaten by deer and/or trampled by cattle. 

A creek runs through the 330 acre property and all along the creek, wherever there is a stone outcropping, there are mortars carved out of the bedrock.

In simpler - and I will always contend it's not overly-romanticizing things to say better - times, folks sat on these stones grinding acorns in these mortars (foreground, filled with rain water) overlooking, and listening to, this beautiful creek.  It was BYOP - Bring Your Own Pestle.

I loathe cooking.  The kitchen is like a prison for me, with too much happening at once in an enclosed space, and with meal time always corresponding to a time when I'd rather just be talking with my family about the events of the day without interruption from timers, food processors and boiling-over pots of pasta.

Or maybe, as my family contends, it's because the same guy who can juggle 50 different things at work can't handle having food cooking on more than one burner at once.

But I could sit for hours - days - in this spot preparing food for the coming year.  The creek, of course, played a vital role in the process.  Shelled acorns would have been placed in baskets in the creek, allowing the water to leach the bitter tannins from the them.

Oh yes, and if you look in the other directions you see this:

And finally this:

 And this is on a "bad" day - foggy and overcast.  Two days earlier this place was bathed in golden sunlight.  Two weeks from now the grass will be green and vibrant.

Yes, even a kitchen-hating dude like me could get used to food preparation - gathering and grinding a years' worth of sustenance within a week or two of work - in a place like this.

And yes, in speaking with the US Department Fish & Wildlife guy who is supervising the project (is it just me or do these guys keep getting younger and smarter?) this area would have been much more heavily covered with oaks - primarily blue oaks (Quercus douglasii) in pre-settlement times.  Most were cut down for firewood, building materials, and to grow more grass for cattle (although the success of this is debatable - studies show that the grass growing in the shade of oaks is more more nutrient-rich).

All of the grass you see is non-native - European annual grasses that replaced the native perennial vegetation, and then got its seasons flip-flopped; it turns golden brown in summer and greens up in winter.  Or what passes for winter in California.  Said the native Minnesotan.

What do you see?

Here's what I see:  possibilities. 

I see mast.  (And by clicking I see an awesome blog.)

I see a simpler, more harmonious time.

I see fodder.

I see the future.

I see dinner.

Blue oak (Quercus douglasii) acorns, Springville, CA.

What do you see?

Coincidence? I think not.

The great observation on the Las Pilitas Nursery web site that in many cases (so-called) hybrids of blue oak and California white oak (a.k.a. valley oak) are more plentiful than pure examples of either "species" had me curious, so I looked up the ranges of both "species" in Oaks of North America.  Here's what I found.

Range of blue oak (Quercus douglasii)

Range of California white oak (Quercus lobata)

Beside the fact that the latter map was apparently rendered with a felt tip pen on the verge of drying out, the two maps look strikingly similar to me.

Hmmm... more hybrids than pure breds, and the exact same range.  Still sure we're talking about two separate "species" here?

Random leaf samples from the blue oak pictured in the previous post (I could reach these from the road without disturbing the bovines).

While searching for more information on blue oaks and leaf photos with which to compare these, I came across more brilliance from the website of Las Pilitas Nursery.  I can't believe I never noticed this before!

Blue oaks (Quercus douglasii) hybridize with many of the other oaks in California and often you're left guessing which it is. Sometimes Blue Oaks (Quercus douglasii) and Valley Oaks (Quercus lobata) get together and you get more hybrids than 'real' trees. Sometimes Blue Oaks (Q. douglasii) and scrub oaks (Quercus berberidifolia) make a mess of little oaks that leave most of us confused and one or two newbie botanists thinking up new species names.

I would be very happy if a group of botanists by consensus combined almost all the oaks into one species, with the subspecies, forms, varieties and hybrids listed under them. THEN, if you were not sure which one you were looking at you could 'go up the tree' one step.


Amen brother (or sister), amen.  When a particular hillside has more "hybrids" than true "species," that should be a clue that our current system of taxonomy is not up to the task of accurately describing oaks.  Regular Oak Watch readers know I am a proponent of a One Species/Many Varieties approach to oak taxonomy - more of a gradient like the three-sided gradient (sand, clay, silt) used to classify soils.

Obviously, I'm not the first.  Or the smartest. Or the most eloquent.  Or... Well now I'm really depressed.  But the point is even though I'm late to the One Species party, at least I'm there. 

You might be asking:  Why does it matter?  Who cares about the taxonomy and nomenclature surrounding oaks, except for a bunch of acorn heads in their ivory towers?

It matters.  It matters because instead of viewing oaks as separate, static "species" that exist only in the realm of "nature," the One Species concepts sees oaks as ever-changing, ever-evolving possibilities - in the same way that a couple of nondescript, virtually inedible grasses ultimately became maize, the oaks we see today could - and I would argue must - become the corn of tomorrow.

Oaks served mankind as a primary staple food source for millennia.  And served mankind well.  Now corn and its cereal counterparts have allowed us to increase our numbers to the point where woody crops as they currently exist couldn't feed the world without selection and breeding.  But corn and its cereal counterparts' effect on the soil which sustains us and fossil fuel consumption have made it imperative that woody crops take their place as soon as possible.

I harp constantly on the genetic elasticity of the Quercus genus - I mean species! - to illustrate how much genetic potential exists within this one remarkable species.  It took corn about 6,000 to completely control our land and our stomachs.  Oaks could regain their rightful position as the Staff of Life in just a few decades - but only if we stop trying to separate them into different species are start viewing them as One Species within which resides the diversity that will save our soils and our souls.

The one of the left is blue oak, Quercus douglasii.  I think the one on the right is coast live oak (Q. agrifolia) but to know for sure I would have had to scale a barbed wire fence into a cattle holding pen.  I wasn't worried about getting hurt or trespassing; I was worried about what I'd step in on the way to a day of sales meetings ;-)
