Wildlife Action Plan 2015 Revision Process White Paper
9. Treats. Following a best-practice guide recommendation (AFWA TWW 2012) , a list of the 11 threats most likely to impact wildlife is considered in this assessment. Te list is based primarily on the defnitions and hierarchical classifcation scheme published by Salafsky et al. (2008) and adopted by the IUCN Conservation Measures Partnership (IUCN CMP 2012) , with modifcations. Te threat of geologic events (volcanic eruptions, earthquakes, and ava- lanches) was eliminated based on an expectation these events will have little to no impact at this time on wildlife in North Carolina. Treats are evaluated based on the anticipated impact to a species. Te list of threats to be considered is provided in Table F.1. Subcategories (1.1, 1.2, 1.3, etc.) for threat categories 1 through 10 are described by Salafsky et al. (2008) and were included as examples to help defne the threat categories and are not scored individually. A threat category for wildlife disease was added because impacts from the spread of infectious disease (e.g., white-nosed syndrome) can pose a signifcant threat to some species. Treat category 11 (Disease & Pathogens) and the subcategories for this threat were developed by the Work Group. Table 2 describes the scope and severity of impact that each threat is likely to have on wild- life. Te scope and severity descriptions are based on the scales outlined in NatureServe’s evaluation assessment report (see Tables 6 and 7 in Master et al. 2012) . Te evaluation uses the Bayesian style analysis shown in Figure 1 to characterize the relationship between scope and severity of the threat. Te relationship between scope and severity of the impact is used to assign an overall risk category of very high, high, medium, low, or not a threat. A score will be assigned to each of these risk categories and the fnal threats score will refect a calculated average for each of the 11 threats listed in Table F.1.
Te threats most likely to impact wildlife
T ABLE F.1
Threat Category 1
Residential & commercial development Treats from human settlements or other nonagricultural land uses with a substantial footprint. Includes housing and urban areas; commercial and industrial areas; and tourism and recreation areas. 2 Agriculture & aquaculture Treats from farming and ranching as a result of agricultural expansion and intensifcation, including silviculture, mariculture, and aquaculture. Includes annual and perennial nontimber crops; wood and pulp plantations; and livestock farming and ranching. 3 Energy production & mining Treats from production of nonbiological resources, and exploring for, developing, and producing petroleum and other liquid hydrocarbons. Includes oil and gas drilling; mining and quarrying; and renewable energy.
