Remarks:
Drainage patterns are present throughout the wetland. Consolidated upgradient drainage braids as
the topography flattens out within the wetland. Surface water is present throughout the majority of
the wetland (depths less than 6"), however the data point location was chosen on a small rise
between drainage patterns without surface water to allow analysis of the soil profile.

Wetland WA has an established canopy layer dominated by American elm. The understory is sparse, and the
herbaceous layer is largely absent except for small pockets of an unknown fescue-type grass. Heavy shading from the
canopy cover and high saturation in the wetland is likely limiting understory growth.
