Description

Recommends which of the over 100 vulnerable species of concern in Pima County should be considered for coverage under the County's future permit and further analyze approximately 50 animals and plants as potentially covered species under the multi-species conservation plan.

Identifies key potential threats and stressors to vulnerable species in Pima County, and to the biological and hydrological resources that support these species. Emphasis has been placed on identifying the specific components of past, existing, and proposed land and water uses that pose the greatest potential threats over the next

Identifies key potential threats and stressors to vulnerable species in Pima County, and to the biological and hydrological resources that support these species. Emphasis has been placed on identifying the specific components of past, existing, and proposed land and water uses that pose the greatest potential threats over the next 30 years to focal species and special habitats, plant associations, and communities.

Mr. Proudfoot, the leading pygmy-owl biologist in the United States, has worked for the last two years to gather and analyze the data that allows us to address issues regarding the genetic viability of ferruginous pygmy-owls in Arizona and to establish a framework for future management efforts. The two major questions addressed are (1) do populations of concern lack genetic variation relative to putative healthy populations, and (2) how unique are geographically distinct populations within a species of special concern?

Description

A preliminary analysis that has been drafted in conjunction with participating federal agencies. Land managing entities provided information and later a detailed review of fact sheets that summarize each reserve in terms of its size, ownership, authorizing documents, land use activities, priority vulnerable species, exotic and non-native species, baseline information,

A preliminary analysis that has been drafted in conjunction with participating federal agencies. Land managing entities provided information and later a detailed review of fact sheets that summarize each reserve in terms of its size, ownership, authorizing documents, land use activities, priority vulnerable species, exotic and non-native species, baseline information, GAP status, acquisitions, management plans, research, monitoring and recovery programs. The study proposes eight Reserve Management Areas that include land managers who could work together across administrative boundaries.

Description

An assessment of the problems that are presented by non-native and introduced species in maintaining native species and natural systems. Divided into two major sections, the study covers representative ecosystems in Pima County as well as representative species that have a negative impact on native species.

Describes methods that are used in order to prepare reserve design alternatives in the area of biological conservation. The report also provides a brief history of reserve design theory, and demonstrates how the principles of biological reserve design have been extended to the other Elements of the Sonoran Desert conservation
