From rooting up crops to destroying farm infrastructure, Louisiana’s rising inhabitants of feral hogs causes $91.1 million in harm to agricultural and timber lands every year, in accordance with a newly launched LSU AgCenter estimate.
Based mostly on responses to a 2021 survey, the examine discovered that hog harm prices landowners $66.2 million in crop losses and $24.9 million in different bills yearly. Greater than 950 folks accomplished the survey, representing practically 660,000 acres of crop fields, pastures and woods.

The examine signifies annual manufacturing losses have been biggest for sugarcane, rice, corn, hay, soybeans and timber. These losses ranged from $6.9 million for timber to $14.8 million for sugarcane.
A couple of quarter of the 952 respondents reported harm to pastures, one thing the examine leaders estimate to price $5.4 million statewide yearly.
