  1. Translocate adult or juvenile reptiles: Snakes

    A controlled study in 1992–1994 in a site of deciduous forest in Arkansas, USA (Plummer & Mills 2000) found that translocating eastern hognose snakes Heterodon platirhinos resulted in only one surviving until hibernation. Similar numbers of translocated snakes were predated (5–6 of 8) compared to resident snakes (6 of 8). Translocated snakes survived 3–75 days, whereas residents survived 24–183 days (values taken from table). Average movement of translocated snakes (120 m/day) was similar to residents (119 m/day), but variability in daily movement was nearly six times higher for translocated snakes than residents. Translocated snakes were captured offsite from various localities 8–40 km from the translocation site and resident snakes were captured on site. Snakes were implanted with radio transmitters and released within 5 days of capture in a grassy clearing.  Snakes were located daily from April to October 1992–1994.
