A broad range of information is needed on the ecology of large mammals in a variety of situations. Ecological factors resulting in excessively high or low populations need to be determined.
Information needs to be developed for ecologically sound management of large mammal species.
A variety of management problems in several parks generate the need for ecological information. Archeological resources are adversely affected. A research program is needed to determine population numbers and trends, and to evaluate the effects of these high populations. Ecological information should help mitigate the problem. Bighorn sheep populations are declining in certain areas of Grand Teton National Park.
