  1. Translocate adult or juvenile reptiles: Snakes

    A controlled study in 1990–1994 in a site of mixed broadleaf forest in Pennsylvania, USA (Reinert & Rupert 1999) found that translocated timber rattlesnakes Crotalus horridus had higher mortality and moved longer distances than resident rattlesnakes. Translocated rattlesnakes had higher mortality (55% died; 6 of 11 rattlesnakes) than resident rattlesnakes (11%; 2 of 18 rattlesnakes). Translocated snakes had higher daily movements (average daily movement: 55–124 m) compared to resident rattlesnakes (10–37 m), moved more overall in two of three comparisons and had larger ranges in nine of 12 comparisons (see paper for details). In 1991–1992, eleven rattlesnakes (five females, six males) were equipped with radio transmitters and translocated between eight and 172 km from point of capture. In 1990–1992, eighteen resident rattlesnakes (10 females, eight males) were also monitored using radio telemetry. Rattlesnakes were located once every two days for six months of the year (mid-April to mid-October) for up to a year.
