Call to Order

Minutes from the April 24th Meeting
Minutes for the April 24, 2000 STAT meeting were approved by all members present.

Land cover subcommittee
Some of the land cover maps being reviewed by the Arizona Game and Fish Department have been returned with good comments from the wildlife managers. This is especially true for the Altar Valley area, where some new locations of perennial stream reaches and springs were drawn on the map. Pima County received a vegetation map for the Saguaro National Park, which is currently being converted to the Brown, Lowe and Pase system for the composite land cover map. Pima County has also obtained a map from the U. S. Geological Survey that displays geologic deposits for the county. This is being analyzed for the high priority carbonate deposits which may be sources for specialized habitats. In addition, an analysis of discrepancies between the composite land cover map and vegetation transects performed during the Pygmy-Owl field surveys was passed on to RECON to help update vegetative cover.

News from other elements of the SDCP
So far, approximately 60 reports have been completed within the last 120 days following the hiring of the biological consultants. These reports, and others currently in progress, will be used by members of the Project Management Team to write documents on the six elements of the Sonoran Desert Conservation Plan. These documents, in turn, will be synthesized to form one large document for the SDCP.

The U. S. Fish and Wildlife Service will perform a scoping process to obtain public input regarding the Section 10 permits which Pima County will be seeking as part of the SDCP. This is the first step towards obtaining Section 10 permits, and must be completed prior to performing the Environmental Impact Statement for NEPA. Background and procedures for the scoping process will be published within the Federal Registry and advertised through local media.

Criteria for permits subcommittee
Bill Shaw provided a handout displaying criteria for obtaining Section 10 permits. This chart was created by Bill with help from Mima Falk and Sherry Barrett, who provided background information. Some suggestions were made by members of the STAT and others regarding a statement for higher standards than the legal minimum and a criterion for adaptive management. The handout will be revised to reflect comments made during the meeting and any others received before the next meeting.

Decision-Support Model subcommittee
Julia Fonseca provided a brief overview of the meetings that were held with Peter Stine and members of the subcommittees responsible for providing input on target species for the Decision Support Model. The Pima Pineapple Cactus and Cactus Ferruginous Pygmy-Owl appear to be good target species and the subcommittees will work to provide data to the Decision Support Model (DSM) team. The subcommittee for riparian habitat recommended reducing the scope of the target and just focus on the cottonwood-willow series. It was deemed that all mesoriparian habitat as a target was too impractical, and a smaller target needed to be identified. The subcommittee for ranid frogs decided that the existing locations for these species would not be a good target for the DSM and should be considered as a constraint for the model instead. Three tiers were created for the ranid frogs: protection of existing habitat (constraint), managing exotic species (target) and restoring hydrology (target). The group is working to provide better data and identify conservation and restoration activities needed for native frogs.

Robert Steidl gave a brief description of the last target, which will be to use the information provided in The Nature Conservancy's "Sonoran Desert Ecoregion Plan". The subcommittee will create their own preserve alternatives based on the processes and data within the TNC document.

The next meeting day for the subcommittees will be on July 27, 2000. The July STAT meeting will also be held on that day to better utilize everyone's time.

Announcements
Nathan Sayre announced a field trip opportunity for the STAT with the Ranch Conservation Technical Advisory Team (RCTAT) to visit either the Empire-Cienega or Arivaca ranch areas. Possible dates for the field trip include July 26, July 28 and August 14. A more confirmed date and place will be provided at the next STAT meeting.

Riparian mapping report
Lisa Harris provided a brief overview of the riparian mapping effort by the Harris Environmental group. About 75% of the coverage has been delineated onto quads, and Russell Duncan and others are looking at the maps and providing their input.

Vulnerable species data summaries
The RECON group has completed data summaries for the vulnerable species that were listed for their potential inclusion for take permits (56 species total). The report should be out by the week of May 29, 2000. The consultants will continue working on the distribution for each of the species summarized.

Non-native species
Neva Connolly completed a draft report on non-native species management within reserves and other protected areas. This report focuses on the overall problems within these areas, not on individual species. Copies were passed to those who wished to review the report. Comments are to be received by June 1.

Problematic Species
RECON provided a list of all the problematic species listed for the SDCP in the package sent to the STAT for this meeting. In addition, they provided a "top ten" list of species that are proposed for further detailed analysis and a short discussion of other species and possible approaches for handling this issue. After a brief discussion, STAT decided that the best approach would be to focus on ecosystems, rather than requiring individual species summaries.

Riparian restoration guidelines
A handout containing the riparian restoration guidelines was provided in the package sent to the STAT. Bob Steidl said that native plants must be used for restoration efforts. Sherry Barrett suggested that the guidelines should included a statement stressing the need to avoid creating unnatural water bodies that would promote invasive, non-native species. Any other comments regarding these guidelines should be sent to Julia Fonseca.

Preserve/Reserve design guidelines
A handout displaying the reserve guidelines was provided in the package sent to the STAT for this meeting. A brief discussion was held regarding these guidelines, resulting in some word changes and a revision to the biological goals statement for the STAT. The revision changes the words "habitat conditions" to "ecosystem structure." Julia Fonseca will revise the biological goals accordingly and provide copies to the STAT at the next meeting. Due to a lack of time and a number of members missing in attendance, it was decided that this discussion should be held over for the next meeting.

Call to the Public
No comments.

Future Meeting Dates

The next meeting of the Science and Technical Advisory Team has been rescheduled to June 23, 2000. The meeting will be held from approximately 9:00 A.M. to 11:30 A.M., at the Water Resource Research Center. Future meeting dates include: July 27 (also revised), August 21, and September 18. Times will be the same as above, unless specified otherwise.
