Days 296-299 (part 1)
Artists Week.
Kai
led us in a plant identification walkabout. He talked about how our
local high-mountain desert ecosystem is fire-adapted, with the tall coniferous
trees dropping their lower limbs and developing thick fire-resistant bark. He noted that dense stands of saplings and small trees that bridge the gap between the ground and the upper branches of the mature trees are a fire hazard, so it behooves us to thin out these smaller trees.
He also talked a bit about botany, noting the distinction between gymnosperms, (like our familiar coniferous trees,) which have unenclosed or naked seeds, and angiosperms, which are flowering plants. Angiosperms are further divided into monocotyledons and dicotyledons. Among other distinctions, monocots typically have leaf veins that run parallel, flower petals in multiples of 3, and fibrous
roots, whereas dicots typically have branching leaf veins, petals in multiples of 4 or 5, and
root systems with a taproot.
We walked around and Kai pointed out a variety of plants still identifiable even in the winter, noting some of their edible,
medicinal, or other values. Plants we saw and talked about on this short walk included: mustard, pepperweed, knapweed, pseudo-lamb's quarters, white sweet clover, western larch, rye, douglas fir, saskatoon, nine bark, yarrow, mullein, ponderosa pine, oregon grape, black tree lichen, crustos lichen, sedges, bedstraw, timothy grass, evening primrose, sunchokes, rudbeckia sunflowers, tansy, rocky mountain bee plant, and hairy vetch. We talked about a few other plants too; dandelion, kinickinick, snowberry, grand fir, lodgepole pine, and western cedar, but during our walk we didn't specifically see these or the many other plants that can be found around the labs. We also saw at least one plant that, while familiar and abundant, none of us could positively identify.
Thanks for leading our plant id walkabout, Kai!
