- •
Ecological and economic impacts of rooting disturbance by feral swine were examined in south-central Florida rangelands.
- •
Plant diversity response to rooting disturbance was dependent on initial levels of diversity.
- •
Palatable forage grasses were lower whereas weeds and unpalatable plants were greater in rooted versus unrooted areas.
- •
Forage loss was estimated to be >85 acres of pasture per 1000 acres.
- •
Regionally forage losses were conservatively estimated to cost >$2 M/per year.
