FACTORS AFFECTING THE SPECIES Sample Clauses

FACTORS AFFECTING THE SPECIES. ‌ When considering if a species is warranted for listing, USFWS assesses the status and threats to a species based on five factors provided in Section 4(a)(1) of the ESA (16 U.S.C. 1533). These five factors were considered when the xxxxxx was proposed in October of 2014 for federal listing as a threatened or endangered species in all or part of its West Coast DPS (USFWS 2014b). The xxxxxx was once widely distributed throughout forested areas of western Oregon, but due to logging, unregulated harvest, and perhaps incidental mortalities associated with predator control efforts, the range in Oregon has been reduced to one remnant indigenous population and one reintroduced population in southwestern Oregon (Xxxx 1979, Xxxxx and Xxxxx, 2003, ODFW 2006, Fig. 1)

FACTORS AFFECTING THE SPECIES. ‌ When considering if a species is warranted for listing, USFWS assesses the status and threats to a species based on five factors provided in Section 4(a)(1) of the ESA (16 U.S.C. 1533). These five factors were considered when the xxxxxx was proposed in October of 2014 for federal listing as a threatened or endangered species in all or part of its West Coast DPS (USFWS 2014b). Washington’s xxxxxx population had been extirpated from the state since the mid-1900s as a result of historical factors that included the overexploitation of fishers for their pelts; mortality as a result of incidental capture, predator control programs, and poaching; and loss and fragmentation of low-elevation forested habitats (Xxxxx & Xxxxx 2003; WDFW 1998). WDFW has been working to reintroduce fishers to Washington and relies upon the cooperation and partnerships of federal, state, tribal and private landowners for xxxxxx recovery.

FACTORS AFFECTING THE SPECIES. When considering if a species is warranted for listing, the USFWS assesses the status and threats to a species based on five factors provided in Section 4(a)(l) of the ESA (16 U.S.C. 1533). These five factors were considered when the island marble butterfly was proposed as endangered in April 2018 (83 FR 15900). The island marble butterfly faces the following threats:  Habitat loss and degradation from plant succession and invasion by plants that displace larval host plants; browsing by black-tailed deer, European rabbits, and brown garden snails; and storm surges;  Predation by native spiders and nonnative wasps, and incidental predation by black-tailed deer; and  Vulnerabilities associated with small population size and environmental and demographic stochasticity, and other chance events that increase mortality or reduce reproductive success. ENROLLED LANDS Lands eligible for enrollment in this CCAA include state, tribal, non-federal publicly owned or privately owned lands on San Xxxx Island and Xxxxx Islands in Washington. Within San Xxxx and Xxxxx Islands, we are specifically seeking voluntary enrollment from landowners or their designees within the expansive, non-forested, open landscapes in the San Xxxx Valley and Xxxxx Island central valley that have the highest potential to develop closely connected habitat patches that could support the long-term conservation of the island marble butterfly (CCAA Emphasis Areas) (Figure 2). Lands on each island which lie outside of the CCAA Emphasis Areas may also be eligible for enrollment, if determined suitable for enrollment (has sufficient amount of non-forested open space San Xxxx Island or Xxxxx Island) by both the WDFW and the USFWS. Enrolled properties will be described in documentation incorporated into Certificates of Inclusions, and will include maps, figures, and/or legal descriptions as necessary to clearly delineate the precise boundaries of areas covered. The WDFW will maintain an inventory including descriptions of all enrolled properties and provide this information to the USFWS as one component of an Annual Report quantifying the amount and location of the enrolled properties.

FACTORS AFFECTING THE SPECIES. ‌ In 2015, the Service re-evaluated the status of the Sonoran desert tortoise, a Federal candidate species as of 2010. This evaluation included a Species Status Assessment, or SSA. The SSA process included assembling a team of the most knowledgeable experts on Sonoran desert tortoises in private and public sectors to collect, evaluate, and model information on the species’ needs, potential habitat, and what predominate risk factors may be affecting, or could affect, population resiliency, redundancy, and representation across its range in the foreseeable future. To assist with this process, the Service contracted the development of a population viability model capable of running hundreds of thousands of simulations, hundreds of years into the future, under a widely varied array of possible baseline conditions. Collectively, this process identified six primary risk factors that could affect Sonoran desert tortoises on a regional or rangewide scale. These risk factors were: 1) altered plant communities; 2) altered fire regimes; 3) habitat conversion; 4) habitat fragmentation; 5) human-tortoise interactions; and 6) drought associated with climate change.
