Summarizes the attached resource reports that have been submitted so far to help develop the SDCP within the watershed planning area of the Altar Valley. This initial presentation of resource information is intended to both educate and serve as an invitation to greater participation in crafting the SDCP.
Arivaca, located on the southern border of Pima County, is one of the few remaining riparian areas in southern Arizona. This report presents collected data, shows how the Arivaca area relates to the SDCP, and makes recommendations on how the plan could address pressing groundwater issues in the Arivaca Valley.
A companion to the "Importance of Conserving Resources in the CIenega Creek Watershed" document and provides a focus on Altar Valley. This report includes detailed investigations into the historic conditions of the watershed, current rangeland conditions of biotic communities, and the environmental impact of a potential floodplain project.
Study of 30 surface and 18 archaeological-context pollen samples was undertaken to assess the potential for further archaeological palynology research. Surface sample analysis allows palynological recognition of eight habitat types ranging from dry and cold through wet and moist to dry and warm. Comparison of fossil and modern surface pollen data suggests the character of paleoecological change sequences at 4 sites, a positive potential for inter-site and intra-site relative cross-dating, and a positive potential for inter-regional dating on paleoclimatic grounds.
