SCWDS Feral Swine Maps

►Initial series of maps completed in 1982 ►Funded by USDA-APHIS-Veterinary Services ►Original series included FMD-susceptible

species: white-tailed deer, elk, moose, mule deer, black-tailed deer, bighorn sheep, Dall’s sheep, mountain goat, collared peccary, and feral swine

Data Collection

►National feral swine maps completed in 1982, 1988, 2004, 2008, 2009, 2010, 2011 and 2012

►Data collected nationally from state wildlife resources agencies 1982-present

►Data collected from state/federal wildlife and agriculture agencies 2008-present

Report Feral Swine

►Used for submission of distribution reports; password protected

►Distributions can be added or deleted ►Data entered as populations or sightings ►Passwords assigned to state wildlife agency

representatives in every state ►Representatives can submit potential map

updates as data are available

Distribution Criteria

►Maps are of established feral swine populations Distributions as reported by designated

personnel with state and/or federal agencies Feral swine considered established where they

have been present for two or more years and where there is evidence of reproduction

Expansion of Feral Swine Established Feral Swine Populations

► 1982: 17 states ► 2004: 28 states ► 2011: 37 states ► 2012: 36 states

Feral Swine Distributions

1982

2010

Factors Associated with Spread

►Dispersal of feral swine from extant populations

►Escape/release of domestic/penned swine ►Transport and release of feral swine

Status

►NFSMS operational since January 2008 ►Quality of the maps depends on the data

provided by state/federal agencies ►Since January 2008 over 600 additions have

been made to the map ►Current reported distribution now includes

36 states with established populations

Collaboration

►Providing maps and GIS datasets to state and federal wildlife and agriculture agencies and universities for use in ongoing research and management

►(USDA, USFWS, BLM, NPS, DOHS, DOD, DOT, CDC, state wildlife agencies, state agriculture agencies, state parks, media)

►We can provide state, regional and national maps for any years that we have data
