The reference domain is defined as all wetlands within a specified geographic region that belong
to a single hydrogeomorphic (HGM) subclass (Smith et al. 1995). The reference domain for the riverine
class, low-gradient, blackwater stream, bottomland hardwood forest wetlands is shown in Figure 2. The
reference domain for this subclass consists of those counties in peninsular Florida that are within the
Southwest Florida Water Management District. This HGM subclass excludes wetlands that are influenced by
tidal waters with salinities of 0.5 ppt or greater.
