Brown Treesnake trap captures, Guam National Wildlife Refuge, 2014

Over a 22-week period both with and without active Brown Treesnake (BTS) snake removal, we evaluated snake-trap contact rates at mouse- and bird-lure traps within the Guam National Wildlife Refuge in 2014. Bird-lure traps served as a proxy for reintroduced nesting birds. Data consists of 3 files generated from camera surveillance and trapping using mouse and bird lures in conventional snake traps on a 6 x 18 trapping grid. Trap survey effort contains summary results for a set of traps on a single occasion. Mark release data consist of individual capture records of trapped snakes. Camera transcription consist of animals detected via motion and time-lapsed photography at traps using bird lures.
