Sparse stand of varing ages. PICO, ABLA2, TSME present. Sparse undergrowth. Beargrass, lupine, some arnica and other grasses in patches. Approximately 1/2 of the plot lies in the lava bed where there is no vegetation. But the lava bed has a nice diversity of crusts which we were unable to represent since we have no hammer & chisel. This is a typical high alpine plot - dry, not too diverse. Slope 15%. Aspect 190°. Abundance code: 4 Substrate: lava rock.
