Environmental Factors

With the headwaters of three continental drainages located in Glacier Park, flora and fauna have diverse affinities with many species occurring near the geographic limits of their range. Even slight differences in elevation and directional exposure can radically alter the occurrence of specific habitats and, hence, the distribution of plants and animals.

Monitoring changes to the environment, such as impacts due to global climate change and the spread of exotic species, is matched with serious restoration efforts. We want to pass this place to future generations the way it is today, or better.

Geologic Activity

These mountains are a place of constant activity.

Hydrologic Activity

Glaciers and snowpack feed hydrologic activity throughout the summer.

Nonnative Species

Invasive plants and aquatic species threaten native species existence, spurring park restoration efforts.

Water Quality

As the nation's headwaters, Glacier waters are worthy of protection.

Areas of Concern
Presently, 140 plant and animal species found in Glacier Park are listed by the state of Montana as "Species of Special Concern", four are federally listed as "threatened" (bald eagle, grizzly bear, lynx and bull trout), one is designated "endangered" (gray wolf) and one (slender moonwort) is a candidate for federal listing. The preservation and maintenance of Glacier's resources is a daunting task for park managers given the growing list of threats, including some that are global in scale such as a warming climate. The introduction of invasive, nonnative (exotic) plant and fish species are major issues too.
