APPENDIX X 385
COMPARISON OF VALUES OF HABITAT SUBTYPES BY SYSTEM
The Values to SGCN were derived from the number and Tier level of SGCN associated with each
subtype. They indicate the relative importance of various habitat subtypes to SGCN and provide
guidance in predicting were actions will benefit more and/or higher tier SGCN. Values are most useful
when comparing related habitat subtypes. Three major complexes of related habitat subtypes have been
identified for value comparisons. These complexes are: 1) Terrestrial (Terrestrial, Wetland,
Subterranean and Anthropogenic subtypes); 2) Lotic and Lentic (Streams and Lacustrine
subtypes); and 3) Marine, Estuarine and Estuarine Fringe. Values for all subtypes in descending
order and within each complex are provided in the following four tables and again in each subtype's
description.
