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.
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.
Four adjacent ranges define the western edge of the Avra and Altar valleys. Even though desert ironwood has dark green, lush foliage much of the year, this tree is almost exclusively a Sonoran Desert species. The same is true of the distribution of saguaros, foothill palo verdes, fishhook barrel cacti, and most of the hundreds of other plants growing here. These rugged ranges also provide natural refuges for a variety of wildlife, including desert bighorn and migratory pollinators. In addition to the biological resources, the area has abundant rock art sites and other archaeological sites.
Provides a brief summary of a compilation of resource investigations that have been submitted so far, to help develop the SDCP within the watershed planning area of the Avra Valley. The report also includes a number of proposals related to the Ironwood Preserve.
