The U.S. Fish and Wildlife Service (Service) is the lead agency responsible for recovery of the Mexican wolf, pursuant to the Endangered Species Act. The Mexican Wolf Recovery Program essentially is separated into two, interrelated components: 1) Recovery – includes aspects of the program administered primarily by the Service that pertain to the overall goal of Mexican wolf recovery and delisting from the list of threatened and endangered species, and 2) Reintroduction – includes aspects of the program implemented by the Service and cooperating States, Tribes, and other Federal agencies that pertain to management of the reintroduced Mexican wolf population in the Blue Range Wolf Recovery Area, which consists of the entire Apache and Gila National Forests in Arizona and New Mexico. This report details all aspects of the Mexican Wolf Recovery Program.

The Mexican gray wolf subspecies was listed as endangered in 1976. In 1998 a nonessential experimental population was established in New Mexico and Arizona. Eleven captive-born and reared animals were released into the Blue Range Wolf Recovery Area. In June 2007, the U.S. Fish and Wildlife Service contracted with D.J. Case and Associates to assist in planning and implementing public input for a scoping process to identify issues to consider in developing alternatives preparatory to development of a new Environmental Impact Statement for the Mexican gray wolf introduction program.

The southwestern United States and Sonora, Mexico are the extreme northern limits of the jaguar’s (Panthera onca) range, which primarily extends from central Mexico south through Central and South America to northern Argentina. Recently, the jaguar ranged as far north as Arizona, New Mexico, and Texas. Over the last century, the jaguar’s range has been reduced to approximately 46% of its historic range due to hunting pressure and habitat loss. The greatest loss of occupied range has occurred in the southern United States, northern Mexico, northern Brazil, and southern Argentina. Since 1900, jaguars have been documented occasionally in the southwestern United States, but the number of sightings per decade has declined over the last 100 years with only 4 verified sightings between 1970 and 2000. The objectives of our analysis were twofold: (1) characterize potential jaguar habitat in Arizona from historic sighting records, and (2) create a statewide habitat suitability map.

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.

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.
