If one species had to be chosen to preserve and restore, perhaps it should be cottonwood. Cottonwood-willow forests, where they exist and are healthy, indicated the presence of a viable riparian area, which is in turn the key to conserving great proportions of our native species. A reflection of the

If one species had to be chosen to preserve and restore, perhaps it should be cottonwood. Cottonwood-willow forests, where they exist and are healthy, indicated the presence of a viable riparian area, which is in turn the key to conserving great proportions of our native species. A reflection of the dire status of our riparian systems is that the Sonoran cottonwood-willow and Sonoran mesquite-cottonwood forests.

Surveys were conducted for Huachuca water umbel at the Cienega Creek Natural Preserve, the Bingham Cienega Preserve, and the La Cebadilla property. Because the plant was detected in sites that are further north and at lower elevations than previously considered, the study recommends that assumptions regarding the potential presence of the species throughout Pima County should be re-examined.

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

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.

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.

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 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.
