Gordon Schuett, a former Arizona State University biology professor who studies Arizona rattlesnakes, said moving a snake any substantial distance is distressful to it. Schuett is among those who say euthanasia by a veterinarian may be kinder. "Reptiles have a keen sense of their home, and what they do is try to find home when you translocate them. If you move them a mile, they either return or get confused," Schuett said. The stress creates hormonal changes that interfere with their ability to find food and makes them more vulnerable to predators and disease, he said. Schuett also sees problems in introducing a snake into a new population.Different groups of snakes have different types of immunities. A snake entering a population can infect the new group or become infected itself with diseases or parasites, said Schuett, curator of reptiles at Zoo Atlanta and a faculty member at Georgia State University. Schuett, who conducts fieldwork in Arizona, co-edited Biology of the Vipers, a book that includes several Arizona studies that show rattlesnakes died after being moved farther than a quarter-mile from home. Kevin Wright, curator of living collections at the Phoenix Zoo, agreed that moving snakes could consign them to a slow death. Wright, a veterinarian and reptile expert, said a good relocation site is hard to find. "If it's a good habitat, snakes are there already. If it's bad, there aren't any snakes," said Wright, adding that survival depends on their prey base. "A little ground snake that feeds on beetles can survive, but rattlesnakes need more." The addition of a single mature snake can throw off the ecological balance of a snake feeding ground. Wright recommends education and tolerance.

For years government and private agencies throughout the west have participated in the relocation of desert pests including venomous reptiles at the request of homeowners and businesses. The relocation of these animals is perceived by the general public and the agencies involved as a humanitarian way of dealing with the problems associated with habitat loss.
Through an Arizona Game and Fish Department Heritage Grant we studied the demographics, mortality, movement levels and the risk of vipirid paromyxovirus transmission in a group of one hundred rattlesnakes (Crotalus spp.) moved by a private fire department from human habitations and businesses as a service to their subscribers in areas around Tucson.
Activity ranges were documented in nine snakes implanted with telemetry transmitters. Twenty snakes were tested for the presence of the humeral antibodies to the vipirid paromyxovirus. Ninety seven snakes were marked with Passive Integrated Transponders before release to insure identification and subsequent analysis of recapture data.
When compared to previous reports on non-translocated rattlesnakes, individual mortality was high, and a majority of snakes showed increased size in their activity ranges. We found no elevated titer for the vipirid paromyxovirus. No information was obtain from recaptured snakes.
Those are but 2 of numerous studies on Relocation of crotalids. Obviously fatalities are high. Obviously there is a chance of introducing something fatal to other animals in the relocated area. I am not going to waiste to much of my time posting every article but the two i posted are from obviously well known and well documented field and lab research. There are many more studies out there all showing High mortality levels when relocation is done.
