Callie Oldfield and Jonathan Evans have published their research on an interaction between wild hogs (Sus scrofa) and yellow nutsedge (Cyperus esculentus) which promotes the maintenance of the nutsedge population. This study took place over 12 years on St. Catherine's Island, and found that wild hogs foraging behavior removed the native plant cover and provided the disturbance necessary for yellow nutsedge populations to rebound clonally. They speculate on whether this is an example of low-level farming in hogs.
