Preliminary field studies at Torres del Paine National Park in southern Chile indicate that the puma (Felis concolor-patagonica) is an important predator on the European hare (Lepus euronaeus) and the guanaco (Lama guanicoe). The project is determining 1) the number and distribution of pumas, guanacos, and hares, 2) year-round food habits, and 3) the impact of pumas on the age structure, sex ratio and population density of guanacos and domestic livestock (sheep and cattle). Pumas are being live captured and released with telemetry radio transmitters to study movements, distribution, and killing behavior. This long term field study is planned to continue for the next 3-5 years
