ABSTRACT: Managed as a renewable natural resource in Louisiana, the American alligator (Alligator mississippiensis) has been estimated to provide 80-90 million dollars of direct economic benefit annually to the state. Feral hogs (Sus scrofa), classified as an “outlaw quadruped” by LDWF, are wreaking havoc on the landscape in every parish of the state. The effects of feral hog depredation on alligator nests are the subject of a 3 year study in southwest Louisiana. The study site experiences regular feral hog eradication efforts by USDA/WS and private landowners. Game cameras were deployed on nests early in the nesting season (July) and retrieved in September after hatching had occurred. In 2014 (Year 1), 78% of monitored nests had hog visits documented on camera. The average number of hog visits was 1.64 visits/nest (Range 1-3). In 2015 (Year 2), 63% of nests monitored were visited by hogs. The average number of hog visits was 5.2 visits/nest (Range 2-14). Additionally, in Year 2, two sham nests imbedded with a player broadcasting recorded sounds of alligator hatchlings were monitored using the same technique. One of the two sham nests was located in an alligator nest that had recently been harvested of eggs; it was visited 30 times by hogs. In 2016 (Year 3), the monitoring of sham nests will be expanded in number and restricted to active nests that have recently had eggs harvested for commercial purposes. Results from Year 3, compiled and incorporated into the data set from Years 1 and 2, will be presented.
