#F'NATWELL <br /> INFINITE SOLUTIONS <br /> METHODS <br /> This breeding avian concern species risk assessment incorporates data from desktop land-cover <br /> review and public data assessment, primarily through a U.S. Fish & Wildlife Service's (USFWS) <br /> Information for Planning& Consultation (IPaC)tool (USFWS 2017). The IPaC report populated a list <br /> of threatened & endangered species (TES) and conservation concern avian species that may occur <br /> in the general geographic region of the Project Area. Atwell then ultilized publically available <br /> information from USFWS and CPW,along with: <br /> • the Second Colorado Breeding Bird Atlas(Wickersham 2016), <br /> • the Avian Knowledge Network(AKN 2017), <br /> • CPW State Wildlife Action Plan(SWAP; CPW2015), <br /> • Species Activity Mapping(SAM)data (CPW 2017b),and <br /> • USGS GAP land cover dataset(USGS 2015) <br /> All these data taken together provided a comprehensive set of information to assess the probability <br /> of occurrence for each of the species based on the individual species' known range, habitat <br /> preferences, breeding occurrence records,and known nest sites. <br /> BREEDING AVIAN RISK ASSESSMENT <br /> Atwell utilized the USFWS IPaC tool to generate a list of breeding avian species that could <br /> potentially utilize the Project Area (IPaC Analysis Table, Appendix 1). A total of 24 TES or birds of <br /> conservation concern were listed as potentially occurring within the Project Area based on the <br /> Project location. After further assessment of the breeding habitat preferences and breeding <br /> occurrence records for the 24 species, it was determined that three (3) species have either a <br /> possible or likely chance of occurrence within the Project Area as nesting species. The breeding risk <br /> assessment for these avian species with a likelihood of occurring within the Project Area are <br /> provided below. <br /> 143 Union Boulevard,Suite 700.Lakewood.CO 80228 Tel 303 462 1100 Fax 303 825 7110 2 <br /> www.atwell-group.com <br />
