Lomatium tarantuloides

"Occurs in dense populations on non-forested substrates, where it is usually the dominant vascular plant species" (Darrach and Hinchliff 2014). "Lomatium tarantuloides is known only from flat to gently sloping southerly to easterly aspects. The plants occupy ephemerally, moist to wet, shallow soils primarily on serpentine/peridotite-derived gravelly sites that become dry and largely barren by late summer. The two known yellow-flowered populations occupy sites with similar characteristics and analogous textured soils, but with substrates of acidic volcanic mudflow parentage. The known sites all show strong evidence of a persistent, fossorial rodent-induced soil bioturbation regime." (Darrach and Hinchliff 2014).
