Takes a comprehensive view of ironwood habitats in both the United States and Mexico, evaluating the ecological and cultural resources supported by the ancient ironwood tree. The study provides an overview of the history and ecology of desert ironwood, and a discussion of the binational research effort undertaken to produce the report.
Provides a brief discussion of the need for the federal government to afford special protection for the Ironwood forest found in the Ragged Top and Silverbell Mountains. A proposed Ironwood Preserve would conserve one of the most valuable stands of the ancient Ironwood forest within the Sonoran Desert ecoregion.
Provides background information on improved mapping techniques that have led to a proposal to update the Watercourse and Riparian Habitat Protection and Mitigation Requirements Ordinance adopted in 1994. New riparian classification maps will be forwarded to the Board to consider for adoption during 2003.
Recommends where riparian land acquisitions would be most effective in serving as mitigation that would cover all priority vulnerable species identified in the SDCP. Priority is given to reaches of watercourses.
