SONORAN DESERT CONSERVATION PLAN

MINUTES FROM THE SCIENCE TECHNICAL ADVISORY TEAM (STAT)
MEETING ON JULY 27, 2000

Attendance: See attached list

Call to Order

Minutes from the June 23rd Meeting
Minutes for the June 23, 2000 STAT meeting were approved by all members present.

News from other elements of the SDCP
The STAT discussed the concerns of ranchers over the effects of the habitat conservation plan on grazing in Pima County. Some concerns, such as taxation and easements, will be addressed outside of the STAT. Wednesday's (July 26) field trip reemphasized the need for better communication between the STAT and the Ranch Conservation Technical Advisory Team on areas of mutual concern and the limits of the STAT's purview.

Bill Shaw will distribute letters, thanking members of the ranch team for running the field trip to Arivaca and the surrounding areas. "Thank you" letters will also be sent to the various property owners for allowing the teams to visit their properties.

Technical Review of Priority Vulnerable Species Information
The STAT discussed technical review of the work submitted by the biological consultants to the STAT. The work to be reviewed includes the complete set of species accounts for the Priority Vulnerable Species, habitat data analysis, reserve design alternatives, species distribution maps, etc. that will be included in the appendices to the habitat conservation plan. The technical review will be performed both on a species-by-species basis and on the collection of species as a whole. Maeveen requested that the time line for review coincide with the riparian mapping effort, which should be completed in September 2000. The reserve design alternatives, which includes plant communities, will be completed sometime in October or November 2000.

Bill Shaw gave two options for the technical review. The first is to form subcommittees to review work on different tasks performed by the consultants. The second proposal was to hire one person to oversee the reviews and bring in outside experts (with STAT oversight) to help in this process. The coordinator would also be responsible for providing a qualitative analysis of the adequacy on species distributions developed by the consultants and performing a sensitivity analysis. All STAT members present adopted the second proposal. Bill Shaw and Julia Fonseca will develop the scope of work (SOW) to hire the coordinator. A draft SOW will be provided to the STAT for review.

Sherry Barrett suggested that the STAT add some species to the list of species recommended for protection under the SDCP: kit fox, desert tortoise, desert bighorn sheep and bears. These species are potential umbrella species that are directly affected by urban development. Protection of these species would help protect a suite of others with smaller home ranges that are threatened by habitat losses due to future development pressures. It was also suggested that these species and others be placed into a species-environment matrix with a ranking or weighting system, and discussed in the narrative for the Reserve Design report.

Riparian committee
A copy of the report on "Aquatic Vertebrate Conservation in Pima County" was provided to all STAT members in attendance. Julia Fonseca asked the STAT identify potential outside reviewers who should receive a copy. Also provided was a handout summarizing the above report and the Water Usage report that is currently being developed by Pima Association of Governments (PAG) for Pima County. Julia Fonseca gave a brief presentation on the PAG report and displayed some maps showing the distribution of wells along some of the major watercourses. In addition, Julia displayed some maps depicting various land forms that were developed using the PAG 208 maps. These maps could be used as yet another tool for updating the land cover map for the SDCP.

Criteria for permits subcommittee
Bill Shaw provided a revised draft of the standard for recommending species for Section 10 permits. Some of the criteria has been revised from earlier versions to allow for accomplishment of the goals. The standards are higher than those imposed by Section 10 of the Endangered Species Act. Copies of this handout will also be provided by e-mail along with a request for all STAT members to vote on adopting, adopting with revisions, or not adopting these standards. The deadline for this vote is August 1, 2000.

Decision-Support Model subcommittee
Peter Stine gave a brief update on the progress of the Decision Support Model teams. So far, four conservation targets have been selected and subcommittees for each are providing information towards the modeling effort. A meeting is scheduled for August 10 in Santa Barbara, California for the teams to focus their efforts. Two major sources of input are still needed from the STAT: more conservation targets and explicit sets of criteria for each target to determine the quantity (numbers or percentage) that the STAT wants to protect. Although it is a difficult process, the latter will be needed to determine appropriate reserve designs for the SDCP.

Additional information needs
A list is required from the STAT to prioritize additional information needs (i.e., species information, land cover, etc.) for the Sonoran Desert Conservation Plan. Peter Stine and Mima Falk have volunteered to help write the proposal and scope of work for improving the existing vegetation maps. Any other suggestions from the STAT regarding this topic should be directed to Julia Fonseca.

 

Fall meeting schedule
The next meeting for the Science and Technical Advisory Team is scheduled for Monday, August 21 from 9:00 A.M. to approximately 11:30 A.M. at the Water Resources Research Center. Other future dates include September 18 (9:00 A.M.), October 25 (1:00 P.M.), November 16 (9:00 A.M.) and December 13 (1:00 P.M.).

Announcements

Bill Shaw directed the STAT's attention to Proposition 101, which would limit the effort of the SDCP if passed. Reasons for not passing this proposition may be obtained at the following Internet site: www.noprop100.com. The STAT should consider becoming involved in educating the public on the effects this proposition would have on the Sonoran Desert Conservation Plan.
