This memorandum analyzed fourteen mapping efforts that have taken place in the past decades, or that are ongoing. About half of these initiatives created data that is useful for a basemap for regional bio-planning purposes. Analysis provides advice about how future research and mapping initiatives within Pima County can gather data in a more effective manner.
Pima County assembled a comprehensive land cover map for the the SDCP and in the process of doing so, identified the strengths and weaknesses of prior mapping efforts. In order to combine the best aspects of past efforts, a common language had to be established among the classification systems.
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.
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.
