Native seed network
USA
The Native Seed Network promotes the use of native plants in ways that support the ecological integrity of both natural and manipulated ecosystems. The Native Seed Network advocates using native plant materials from appropriate genetic sources to conserve biological diversity, and to maintain the adaptive capability of ecosystems, communities and plant populations. The Native Seed Network works with public agencies, educators and private groups to increase the availability of affordable native plant materials. The website is an interactive database of native plant and seed information and guidelines for restoration, native plant propagation, and native seed procurement by ecoregion for the United States.
