Description
The state is dominated with productive stands of Douglas-fir. Ponderosa pine and western larch can also be a component in the stand, along with grand fir. Grand fir is the dominant understory tree in the second level canopy and regeneration. Western hazel is the dominant understory shrub in all of the Plant Community Phases 1.1 to 1.4 and can sprout quickly after fire or release strongly after canopy gaps in mature stands. Fire regimes would be in the stand replacing or mix severity realm occurring 50 to 100 year range.
