Idaho’s quality areas because of disturbance. prior mountain goat management plan (IDFG 1990) addressed vulnerability of mountain goats Historically, there were many more mountain to overharvest, protection of habitat by reducing goats in Idaho than there are today. Open new roads and trails, and translocation of seasons with unlimited tags through the 1950s mountain goats into suitable ranges. reduced mountain goat populations in many areas. Increasingly conservative hunting season This plan is designed to provide guidance to IDFG structure with controlled hunts has helped staff to manage Idaho’s mountain goat habitat stabilize some populations, but others continue and populations over the next 6 years. The plan to decline. Some mountain goat populations directs IDFG to sustain or increase mountain goat translocated into unoccupied areas quickly populations across the state. To accomplish this increased and provided new hunting and viewing goal, IDFG has identified statewide management opportunities. Other translocations failed to direction and strategies, as well as specific establish or increase populations. strategies for each Population Management Unit (PMU). IDFG will engage partners interested Idaho offers few mountain goat tags; tags are in mountain goat management, including highly sought after and demand has increased hunters, federal and state agencies, conservation over time.

However, male mountain populations, healthy habitat, and hunting goats cannot be harvested at rates as high as opportunity. other ungulates, such as deer (Odocoileus spp.) and elk (Cervus elaphus), because they live The draft mountain goat management plan was in low-density populations isolated from one available for comment on the IDFG website for 26 another. days.
