Wildlife not only makes a trip to Glacier memorable, but wildlife is also an indication of ecosystem health. Glacier is lacking basic information about the distribution and abundance of many wildlife species. Some are nocturnal, others secretive, while still others live in isolated areas that are difficult to access. While certain targeted species such as harlequin ducks, raptors, bighorn sheep, and loons have had some study work completed, comprehensive assessments of wildlife in drainages, such as Many Glacier or the upper McDonald Valley, would provide more valuable information about their overall condition. This information will enable park managers to better target and evaluate management actions designed to protect these species and provide a wealth of interpretive and educational material.
