Effects of resource availability and propagule supply on native species recruitment in sagebrush ecosystems invaded by Bormus tectorum

Publications Posted on: September 13, 2010
Resource availability and propagule supply are major factors influencing establishment and persistence of both native and invasive species. Increased soil nitrogen (N) availability and high propagule inputs contribute to the ability of annual invasive grasses to dominate disturbed ecosystems. Nitrogen reduction through carbon (C) additions can potentially immobilize soil N and reduce the competitiveness of annual invasive grasses.
