State 1
Reference State
Description
The Reference State consists of a spontaneous wild condition wherein non-native species are of low abundance and all native species retain viable populations. Structure and function of communities vary according to natural processes and disturbance regimes, with human influences limited to drivers that have the similar outcomes as natural processes. Communities range from marshes and fens to hardwood swamps. Dominant natural processes and disturbance regimes include fire, wind, and beaver activities.

States 2, 5, 6 and 7 (additional transitions)
1.2. Wet Meadow: Carex stricta - Carex spp. Wet Meadow
1.5. Fen: Dasiphora fruticosa ssp. floribunda / Carex sterilis - Andropogon gerardi - Arnoglossum plantagineum Fen
1.6. Emergent Marsh: Schoenoplectus tabernaemontani - Typha spp. - (Sparganium spp., Juncus spp.) Marsh
1.7. Inundated Shrub Swamp: Cephalanthus occidentalis / Carex spp. Northern Shrub Swamp
States 3 and 7 (additional transitions)
1.3. Shrub-carr: Cornus sericea - Salix spp. - (Rosa palustris) Shrub Swamp
1.7. Inundated Shrub Swamp: Cephalanthus occidentalis / Carex spp. Northern Shrub Swamp
Description
The cultural state is actively managed. The structure and composition of cultural vegetation is not self-sustaining without human inputs.
Submodel
Description
The Semi-natural Drained State is modified from reference conditions by draining the site, often followed by temporary cultivation of the site. The vegetation is spontaneously self-generated or self-sustaining in response to both human and natural drivers. However, species composition may no longer indicate wetland definitions, and may consist of a mix of native and introduced species. The degree of isolation from intact habitat and the degree of disturbance will dictate the species composition as vegetation recovers.
Submodel
Description
The Semi-natural State is modified from reference conditions mainly in species composition due to some type of disturbance, but retains a wetland hydrology. The state might have been drained and under cultivation for a time, but subsequently, hydrology is at least partially restored. The vegetation is spontaneously self-generated or self-sustaining in response to both human and natural drivers. However, species composition consists of a mix of native and introduced species. The degree of isolation from intact habitat and the degree of disturbance will dictate the species composition as vegetation recovers.
