The pygmy-owl was listed as endangered in 1997, but notice of the potential listing dates back to 1989. This paper provides a report on pygmy-owl research and rulings, evaluates whether the efforts of the community are leading to the recovery, downlisting and delisting of the pygmy-owl, and concludes that with the exception of valuable in-kind services of the Arizona Game and Fish Department pygmy-owl biologist, meaningful financial support for research and conservation planning efforts has been limited to federal and County contributions.
The purpose of this report is to represent the different types of land stewardship in Pima County in a digital Geographic Information System cover and to update the evaluation of vegetative communities relative to these classes. A previous evaluation suggested that 24 percent of Pima County is in a reserve of some kind; the current evaluation now suggests 26.5 percent.
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.
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.
This preliminary plan serves as a summary of technical and scientific information gathered to date and is intended to frame a broad range of options so that future public participation provides the Board with relevant information that can form the basis of the final plan.
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.
Overview of the Draft Preliminary Sonoran Desert Conservation Plan: Sonoran Desert Conservation Plan
A review and explanation of aspects of the first two years of the planning process, written for the general public to describe in non-technical terms both the procedural and substantive aspects of the conservation planning effort.
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 plan.
The Wastewater Management Department was charged with the task of developing a high volume Sonoran Desert plant nursery within buffer areas of outlying treatment facilities or other regional treatment plants. This report is the result. It also describes certain steps that will allow Pima County to not only accumulate a resource inventory, but to realize that we have a role in the grand tradition of natural history.
