These findings indicate that habitat fragmentation is likely to be the critical factor for species' persistence. Our results indicated that adult eastern indigo snakes have relatively high survival in conservation core areas, but greatly reduced survival in conservation areas along highways and in suburbs. We found a transmitter implantation effect on snake encounter probability, as snakes implanted on a given occasion had a lower encounter probability on the next visit compared with snakes not implanted on the previous occasion. Survival and population growth of a long-lived threatened snake species. We predicted that male snakes in suburbs would have the lowest annual survival. habitat types used by the Eastern Indigo Snakes. The eastern indigos realm is the longleaf pine forest that once covered Florida, Georgia, Alabama, and Mississippi, where it shelters in gopher tortoise burrows to nest and breed. alive or dead) could not be assessed, we employed a multistate approach to model snake apparent survival and encounter probability of live and dead snakes. Established in 1964, the IUCN Red List of Threatened Species has evolved to become the world’s most comprehensive information source on the global conservation status of animal, fungi and plant species. Because of a large number of radio-tracking locations underground for which the state of snakes (i.e. In an effort to estimate snake survival, a total of 103 individuals (59 males, 44 females) were followed using radio-tracking from January 1998 to March 2004 in three landscape types that had increasing levels of habitat fragmentation: (1) conservation cores (2) conservation areas along highways (3) suburbs. These funds will be used in Georgia for the management or restoration of eastern indigo snake habitat, purchase of occupied habitat, purchase of development rights for occupied habitat, or a combination thereof. The eastern indigo snake (Drymarchon couperi) is a federally listed species, most recently threatened by habitat loss and habitat degradation. mitigation for take of the eastern indigo Wildlife Foundation of FloridaEastern Indigo Snake Conservation Fund.
