To evaluate whether VOCs are migrating out of the landfills into the vadose zone, a soil vapor survey of the soil beneath the landfill bases was performed. Permanent vapor monitoring probes were installed and then sampled twice for VOCs. Groundwater beneath the landfills has been impactd by VOCs, namely TCE, DCE, and toluene.

This Additional Site Characterization Work Plan presents a strategy for collecting site characterization information at the closed Maricopa County Cave Creek Landfill to support ongoing remedial action planning for trichloroethene-impacted groundwater underlying the site. The Work Plan supplements previous remedial investigation work plans prepared to characterize the nature and extent of site contamination.

This report and the accompanying Geographic Information System (GIS) datasets summarize the results of the workshop held in Florence, Arizona in 2010. At this workshop, stakeholders representing a broad range of organizations and interests identified and mapped the locations of important wildlife linkages across Pinal County. This report provides background information on the importance and benefits of conserving wildlife linkages for both people and wildlife in Pinal County and describes the methods used during stakeholder workshops and in developing the accompanying GIS products. It includes a series of maps generated from the digitized stakeholder data that depict the general locations of wildlife linkages and potential barriers to wildlife movement within Pinal County. The maps are followed by tables with descriptive information about the habitat areas each linkage connects, the species each linkage serves, and known threats and potential conservation opportunities associated with each linkage.

The Arizona Game and Fish Department held four Wildlife Summits to obtain input from their stakeholders into the development of the Comprehensive Wildlife Conservation Strategy. Stakeholder groups invited to participate in the Summits included Department constituency groups, special interests, local governments, Native American tribes, interagency cooperators, and the general public. This report combines the votes from each of the four Summits into one database for analysis. The results for each individual Summit are attached as separate reports. Comparisons are made in this combined report to show differences between the results of individual Summits. The combined results have also been analyzed to determine if there were any significant differences in opinions of the various stakeholder groups. Demographic breakdowns of the individual Summit results are not included in the separate reports because they would not be statistically valid given the small number of participants at each Summit. Participant comments are included in the
individual Summit reports.

Identifying the primary managers of wildlife habitat can provide one useful type of information for development of Arizona’s Comprehensive Wildlife Conservation Strategy. This can contribute to satisfying at least three of the required elements: #4 (conservation actions and priorities), #5 (monitoring plans), and #7 (coordination). This can be particularly useful in the prioritization of actions and resources.

Toward that end, The Nature Conservancy has compiled relevant information and conducted new analyses from our recent statewide efforts to map and analyze two natural communities, grasslands and forests, and a species group, native fish. The results are presented in three sections, with appendices describing data sources.
