Mariposa County allocates $10,000 from Fish and Wildlife fines for feral hog mitigation

Mariposa County supervisors voted Jan. 7 to transfer $10,000 from the county’s Fish and Wildlife fines and fees fund to the Agricultural Commissioner's budget to support a feral hog mitigation pilot addressing growing damage to agricultural lands and watersheds.

Agricultural Commissioner Monica Nielsen told the board the county recently took responsibility for local wildlife mitigation services after a prior federal arrangement ended, and staff have documented a sharp rise in feral swine populations. “Pigs can have 2 and a half litters a year ... a sow will have a litter on the ground and they can rebreed within 3 days of having that litter. So that is how fast these pigs can recreate a next generation,” Nielsen said, urging the board to fund traps and specialist staff time.

Why it matters: Feral hogs damage agricultural fields and wildlife habitat, root streambanks, pollute waterways, and can carry animal diseases. In a small county such as Mariposa, officials said, an influx of feral hogs can cause outsized economic and environmental harm for ranchers, orchardists and riparian habitat.

What the board approved: The county will transfer $10,000 from the Fish and Wildlife fees and fines fund into the agricultural commissioner’s budget to pay for a feral swine mitigation program. Nielsen said the county’s wildlife specialist has built 12 hog traps with the help of Mariposa FFA students; she estimated the construction cost for traps at about $4,800 apiece when produced locally and significantly higher if shipped in from out of state.

Program details and process: Nielsen described a process in which the county’s wildlife specialist will work with property owners, deploy game cameras to monitor activity, obtain depredation permits when hogs cause damage, and assist landowners in setting traps and removing animals. She said the county’s specialist is already working with homeowners and will liaise with the California Department of Fish and Wildlife on permits and procedures. The county’s phone line for agricultural questions is (209) 966-2075; Nielsen said after-hours calls can be routed to the wildlife specialist.

Public comment: A resident asked whether hunting seasons or public harvesting could be used as a mitigation tool; Nielsen said there is no statewide “feral hog season” in California and explained the county’s program relies on depredation permits and targeted trapping. Another resident praised involvement of Mariposa FFA students, and Nielsen said staff plan to invite students back to observe necropsies and learn about wildlife management.

Board action: Supervisor Dannette Toso moved the transfer; Supervisor Poe seconded. The motion passed unanimously, 5-0.

Ending: County officials said the program aims to reduce feral swine numbers, protect agricultural lands and watersheds, and build local capacity; staff will return with program updates and public information about how property owners can request assistance.
