In March 2020, Pima County released its fourth annual report on its Multi-Species Habitat Conservation Plan (MSCP). The full report can be found on the Pima County website HERE. According to the Executive Summary, six Pima County capital improvement projects and 52 private development projects were “covered” by the MSCP in 2019. While these projects cumulatively had 196.8 acres of impact to the habitat of vulnerable wildlife species, the MSCP required 767.7 acres of mitigation to offset these impacts.
Some other highlights from the report include:
- The Regional Flood Control District reported that 94.5% of applicants avoided impacting regulated riparian habitat.
- The Pima County Board of Supervisors approved several land-use policies that promote reuse or infill instead of sprawl.
- U. S. Fish and Wildlife Service approved a plan for augmenting populations of covered species on our mitigation lands, and another for managing properties along the San Pedro River.
- A new population of Gila topminnow was established in a stream on the County’s M Diamond Ranch.
- During 2019, the portfolio of potential mitigation lands increased by approximately 250 acres.
- Pima County staff, contractors, and volunteers mechanically removed or chemically treated approximately 1,470 acres of buffelgrass on County preserve lands.
- Office of Sustainability and Conservation staff made 623 separate observations on Covered Species; these were reported to the Arizona Game and Fish Department.
- County staff developed comprehensive monitoring protocols for seven monitoring elements, including upland habitat, water resources, landscape pattern change, invasive aquatic and plant species, off-highway vehicles, and climate.
- County staff in partnership with Tucson Audubon Society and the National Park Service established an additional 21 long-term vegetation and soils monitoring plots on County preserve lands.
