In addition to controlling erosion, native species are used for revegetation mainly to maintain the genetic integrity of a site's native vegetation and to ensure the habitat is appropriate for wildlife after reclamation. These aims reflect the department's objective of managing resources in keeping with a landscape's ecology. The following lists of native grasses and legumes are specific to the designated natural regions and subregions of Alberta (see map for Natural Regions and Subregions of Alberta. 1994. Environmental Protection, Edmonton; also Appendix A). These plant species are indicated as natives for their particular subregions by A Guide to Using Native Plants on Disturbed Lands. (Gerling, H.S. et al., 1996. Alberta Agriculture, Food and Rural Development. Edmonton).
Seed mixes that are constituted for particular natural subregions must be based on the pertinent native grasses and legumes species list that follows. Other species not listed may be used in the seed mix, if the Guide indicates that the species is native to that subregion, and the appropriate Forest Ranger District Office approves the use of that native species on the specified site. The Forest Officer may require proof that the species in the seed mix purchased are indeed native before seeding can proceed.
