Translocations: Challenges and Responsive Measures
This is an excerpt from the paper...
Woodrats from a Maricopa County, Arizona suburban community were tracked using radio-telemetry for one to two years to assess differences in home range and mean daily speed between animals left in their original location and those translocated to a nearby nature preserve. The small sample size did not permit determination of differences, and no trends were observed that would indicate observable differences between the translocated and non-translocated individuals. Woodrats that had been returned to their original locations near human development after being captured were located and released at the end of the study, while all but one of the animals that had been transferred to the nature preserve could not be located at the study's end. This study highlights the difficulties in obtaining good monitoring data in translocation efforts. The widespread lack of sufficient monitoring data in translocation programs is of concern to land managers and conservation scientists. More effective monitoring strategies are needed to assess the benefits and risks of animal translocations. IntroductionTranslocations: Challenges and Responsive Measures Wildlife translocations, or the purposeful movement of animals from one area to another by humans, are conducted extensively by natural resource agencies. Griffith et al. (1993) surveyed terrestrial vertebrate translocations in Australia, Canada, New Zealand, and the United States, and found that 50% of surveyed agencies translocated s

. (2001) injected white-throated woodrats subcutaneously with WWAV, resulting in complete infection of the 28 individuals in their study. The woodrats that were infected as adults shed the virus for an average of 59 days. Individuals inoculated at birth shed the virus for 164 days. The authors hypothesize that woodrats infected at birth may shed the virus for their entire lifespan, while those infected as adults would pose a risk to humans for a shorter portion of their lifespan.
White-throated Woodrat Life History and Biology
Nine species of woodrats are distributed throughout the United States. The white-throated woodrat is endemic to the southwestern United States and Mexico, with a range that currently spans California, Nevada, Utah, Colorado, Arizona, New Mexico, and coastal and central Mexico (ôNeotoma albigulaö). While its status in the other states is vulnerable or imperiled, in Arizona and New Mexico it is listed as ôsecureö (ôNeotoma albigulaö). Woodrats are found throughout Arizona counties and publications advise the public how to respond when they appear in urban and suburban environments. Two to three foot high houses or middens are occupied by individual woodrats. Females nest and care for their young within midde
