Translocated males have significantly larger activity ranges, range lengths and mean distances moved per day than native males (Rupert and Reinert, 1992). The remote areas preferred by Timber Rattlesnakes are becoming increasingly less ideal because of enhanced access to such areas via fourwheeldrive and offroad vehicles (Galligan and Dunson, 1979; Brown, 1993).
