Figure 11: Flow Chart to Determine Plant Dominance<br />
Step 1: Determine the number of plant layers. Estimate which<br />
possible layers comprise at least 5% absolute cover of the portion<br />
of the AA that is suitable for supporting that plant layer.<br />
< 5 %<br />
≥ 5 %<br />
It does not count as<br />
a layer, and is no<br />
longer considered<br />
in this analysis.<br />
It counts as a layer.<br />
Step 2: Determine the co-dominant plant species in each<br />
layer. For each layer, identify the species that represent at least<br />
10% of the relative area of plant cover in that layer.<br />
< 10 %<br />
≥ 10 %<br />
It is not a “dominant”<br />
species, and is no longer<br />
considered in the analysis.<br />
It is a “dominant” species.<br />
Step 3: Determine invasive status of co-dominant plant species.<br />
For each plant layer, use the list of invasive species (Appendix IV of<br />
the CRAM User’s manual) or local expertise to identify each codominant<br />
species that is invasive. The eCRAM online interface will<br />
automatically identify known invasive species that are listed as codominants.<br />
