Old-growth mixed and western mesophytic forest characteristics may include high canopy species diversity; uneven-age and size distribution, including several old, decadent, large-diameter tree per hectare; low density and high basal area of canopy trees; and multiple vegetation strata. Additional indicators include the presence of snags and logs in several size and decomposition classes; undisturbed soil with no compaction, well-developed organic layer and soil macropores; and tree-fall gaps of various sizes and ages.
