Project Need
Need For Project:
Assisting with the implementation of the amended Habitat Conservation Plan, will allow us to minimize and mitigate the threats facing tortoises within the Red Cliffs Desert Reserve. Threats include habitat degradation, predation, disease and human related mortality. These threats to tortoise populations are imminent and urgent with tortoise populations declining roughly 50% since long-term monitoring began in 1998. In 2003, tortoise populations declined due to a combination of drought and disease. Catastrophic fires (e.g., 2005, 2020), which burned approximately 25% of tortoise habitat within the Reserve, have degraded habitat. Active management between the cooperative partners of the Reserve (i.e., local city governments, Washington County, Utah Department of Natural Resources, U.S. Fish and Wildlife Service, Bureau of Land Management, etc.) is critical to minimize and mitigate threats to tortoises. Due to the number of potential threats within the Reserve and its proximity to rapidly growing communities, long-term monitoring and active management is critical to determine current management effectiveness, identify future concerns and threats, and ensure the continued existence of tortoises within the Reserve. Washington County has completed the renewal process and it is anticipated that UDNR will increase funding to meet long term commitments for tortoise recovery, with the ultimate goal of UDNR taking over funding and management responsibility for the desert tortoise.
Objectives:
The overall goal of this project is to coordinate desert tortoise recovery activities within southwestern Utah. The objectives of this project include: 1) Perform administrative duties associated with implementation of the amended Washington County Habitat Conservation Plan (HCP); 2) Coordinate desert tortoise recovery activities for the Upper Virgin River Recovery Unit and the Northeastern Mojave Recovery Unit (Beaver Dam Slope Desert Wildlife Management Area); 3) Assist Washington County with regulatory activities (e.g., clearances, presence and absence surveys), monitor incidental take activities associated with the amended HCP, and assist Washington County in surveys on non-federal lands; 4) Implement desert tortoise regional density and population demographic monitoring in accordance with Recovery Plan objectives for the Upper Virgin River Recovery Unit, extending monitoring to the new Management Zone 6; 5) Implement, monitor, and evaluate the translocation of tortoises removed from designated HCP take areas and complete a Translocation Plan; 6) Monitor radio telemetered tortoises to quantify above ground activity patterns, long-term impacts of fire, and long term survival of radioed tortoises within the Red Cliffs Desert Reserve and 7) Develop a long-term management strategy for upland desert tortoise Mojave Desert restoration post burn and assist agency partners in habitat restoration projects on desert tortoise critical habitat within the Red Cliffs and Beaver Dam Wash NCA. Tasks for each objective are described in the Methods section below.

Monitoring:
All HCP activities will be conducted in close coordination with Washington County and the HCAC. Quarterly reports are supplied to the Washington County HCP administration, subsequently distributed to the HCAC, and reviewed by the Washington County Commission. The HCP administration prepares annual work plans and budgets with consultation through the TC and HCAC. UDWR prepares annual reports on population monitoring and other HCP activities for Washington County, the HCAC and TC.
Partners:
This project will be implemented by the Utah Division of Wildlife Resources in cooperation with Washington County Habitat Conservation Plan collaborators including federal (Bureau of Land Management, U.S. Fish and Wildlife Service), state (Utah Department of Natural Resources, Utah Division of Parks and Recreation), local government agencies (Washington County, City of Ivins, Santa Clara, Hurricane, St. George, Springdale) and non-government organizations (The Nature Conservancy, Virgin River Land Preservation Association). In Calendar Year 2021, Washington County will provide $15,000 for assistance with desert tortoise surveys on the Shivwits Band of Paiutes Tribal lands, $35,000 on all other nonfederal lands within Washington County, and $25,000 for desert tortoise fire mortality surveys on recently burned habitat within the Red Cliffs Desert Reserve.
Future Management:
The information obtained through this project will be used to develop management strategies to assist in the implementation of the amended HCP and ultimately the recovery of the desert tortoise. This information will help the HCP staff, HCAC, and Technical Committee better assess potential threats to the desert tortoise population, and understand tortoise survival and mortality within the Reserve. Implementation of the proposed project will result in long-term benefits to tortoise populations by reducing and minimizing threats.
