Provides an overview of the issues related to monitoring the 36 species proposed for coverage under the forthcoming Section 10 permit to the United States Fish and Wildlife Service. By integrating the requirements for MSCP compliance and effectiveness monitoring with the challenges inherent in single-species monitoring, this document seeks a balance between species-specific monitoring and other habitat, ecosystem and threats-based measures (parameters). By designing such a program, Pima County will be in a better position to anticipate and adjust management actions for the conservation of covered species and the ecosystems that support them.
In this survey, we have obtained early photographs from various archives, with dates ranging from 1880 to 1942. We have attempted to provide examples from the main vegetation types that are represented in Pima County. This survey of matched photographs will begin at upper elevations and descend gradually to lower points across the landscape, except that riparian habitat comparisons will be set aside and addressed separately.
During the planning process for the SDCP, concerns were raised regarding loss of property tax revenue as well as adverse tax base impacts of Pima County purchasing parcels for open space. This report assesses impacts in two ways. First, the net assessed values of the open space parcels before purchase are compared to the sum of the net assessed values of all parcels in Pima County and in each applicable school district. Second, the property taxes assessed by Pima County and applicable school districts on each open space parcel before purchase is compared to the sum of the property taxes assessed on all parcels within Pima County and applicable school districts.
This is a non-time opportunity for Pima County to preserve the Bar V Ranch property that has countless benefits. From landscape connectivity for wildlife, to a significant water source for Cienega Creek and the Tucson Basin, to important riparian habitat crucial for the survival of several vulnerable species.
Without action by Pima County, Rosemont Ranch would probably either be mined or become a residential subdivision over the next several decades. A ranch conservation scenario offers the best outcome for preventing fragmentation of the landscape and conserving the natural and cultural heritage of the area.
A report on the proposed acquisition of the Rancho Seco property. The majority of the property is classified within the SDCP as multiple use or recovery management areas. Acquisition of this property is key in keeping Altar Valley intact and undeveloped.
Evaluates the conservation significance of county-owned properties in Avra Valley, specifically with regard to Priority Vulnerable Species and the Sonoran Desert Conservation Plan.
Acquisition of this property in northeastern Pima County will prevent development of this property, conserve an important tributary to the San Pedro River, conserve riparian habitat associated with an intermittent stream and springs, and further goals of the Sonoran Desert Conservation Plan and Multi-Species Habitat Conservation Plan. The acquisition is ideally located to expand the emerging reserve system in the San Pedro watershed, which is anchored by the County's A7 Ranch, and complemented by the existing Buehman Canyon Preserve. This report provides preliminary biological and cultural information on this acquisition. Additional biological and cultural resource information will be available after County staff and consultants complete surveys of the property.
Brings together the findings of previous reports and suggests policies to address water quality issues in Pima County.
These proposals bring together the new policy proposals from the 2001 draft Comprehensive Plan Update and the 1992 Regional Plan and Special Area Policies. One of the proposed regional plan policies suggests that natural and cultural resources should be protected according to their value under a Conservation Lands System.
