The control of vertebrate threats to guams native wildlife project will support the recovery of guams listed native species that have been extirpated in the wild and the conservation of the few extant populations of native birds and mammals. The primary targets are the brown tree snake BTS monitor lizards feral cats and dogsand rodents that pose threats to experimental population of guam rail populations in rota cnmi and islandno guam and at the mangilao captive breeding facility. Control activities will also reduce threats in areas occupied by other native birds such as the slimicronesian starling that persist in reduced numbers and the fanihi mariana fruit BAT. Various control and removal techniques will be used depending on targeted predator some in collaboration with the USDA wildlife services. Two new nonrecurring actions will be added to the PROJECT1 conduct a feasibility study and associated environmental assessment for the eradication of recently detected rodents on island DNO and 2 genetic analysis of the BTS population on island dnoto determine whether its establishment on the island resulted from a singleor multipleevent incursion. Removal or control of these predators will improve reproductive rates and increase survivorship. Without these management interventions the probability that the few remaining populations of these native birds and one fruit BAT species will recover or persist over time is in doubt.
