| Title | Mapping Distributions of Invasive Animals on National Wildlife Refuges |
| Project Description | In this task, we will provide updated information on ranges of invasive bird species using |
| information from the North American Breeding Bird Survey (BBS), and verify the information using |
| refuge checklists and other data sources. Although no comparable information source exists for |
| mammals, general range maps do exist for the taxa, and we will use them to evaluate the ranges |
| of invasive mammal species. The North American Breeding Bird Survey (BBS) contains |
| information on all birds heard or seen on over 4,000 survey routes in North America. Distribution |
| maps made from the data are presently available over the internet |
| (http://www.mbr-pwrc.usgs.gov/bbs/bbs.html), and are used in a variety of studies that attempt to |
| relate resources on NWRs to regional populations. They also show the general ranges of |
| nonnative and invasive species, and indicate what species may be expected to occur on NWRs. |
| In this project, we will revise the BBS maps to incorporate the most recent information on bird |
| distributions, providing lists of predicted invasive species for each refuge from the distributional |
| information. We will also develop range maps of invasive mammal species, using information from |
| NWRs and from other published sources. |
