Using a Diverse Seed Mix to Establish Native Plants on a Sonoran Desert Burn
University of Nevada, Las Vegas
- Revegetating burned areas is a formidable challenge facing resource managers in southwestern United States arid lands.
- Natural revegetation of desert burns by native species may be slow, or dominated by exotic annual grasses that perpetuate a frequent-fire regime.
- Resource managers may have several reasons for actively revegetating burns with native species, such as for providing competition with exotic species, minimizing soil erosion and dust pollution, and improving aesthetics.
- The use of native species in revegetation has been limited by a lack of available seed and by findings that native desert species are difficult to establish (e.g., Bainbridge and Virginia 1990, Banjerjee et al. 2006).
- Seeding may be one of only a few feasible options for reintroducing propagules to large desert burns covering thousands of hectares.
- Our objective was to assess the outcome of a 28-species (all native) operational seeding project for revegetating a 2005 burn in the Arizona Upland Subdivision of the Sonoran Desert.
