However, some trees, such as the smaller ones growing in the marsh at the north end, would not normally be growing in a marsh habitat and have only survived here because the pond level is not fluctuating as much as it would under natural conditions. The large willow trees at the pond's edge would not normally live for a long time anyway for example, not like oaks. They are not native willows, although they are very attractive and do have some benefits for wildlife. Some are falling into the pond on their own, without beaver assistance, and fallen trees in the water can help improve the pond habitat for fish spawning, etc. Some beavers may be roaming ones that have not yet found a place to settle, and they do some tree cutting and then move on.

The beaver Castor canadensis is a keystone species that affects habitat structure and dynamics through the damming and diverting of streams, and the felling of trees and other woody vegetation. The territoriality of beavers probably deters two colonies from locating within feet 50 m of each other, and most streams in the park lack either suitable vegetation or a sufficiently low gradient to provide beavers with habitat, but information about the distribution and number of beaver colonies in the park over time adds to our understanding about the long-term effects of changes in vegetation and climate. Beavers live throughout Yellowstone National Park but are concentrated in the southeast Yellowstone River delta area , southwest Bechler area , and northwest portions Madison and Gallatin rivers of the park. These areas are likely important habitat because of their waterways, meadows, and the presence of preferred foods such as willow, aspen, and cottonwood. However, beavers are not restricted to areas that have their preferred foods. In these areas, beavers use willows for construction and for food. Where their preferred plants are few or absent, beavers may cut conifer trees and feed on submerged vegetation such as pond lilies. Beavers are famous dam builders, and examples of their work can be seen from the roads in the park. Most dams are on small streams where the gradient is mild, and the current is relatively placid during much of the year. Colonies located on major rivers or in areas of frequent water level fluctuations, such as the Lamar River, den in holes in the riverbank. An old dam is visible at Beaver Lake between Norris and Mammoth. When hunched over their food, beaver can resemble round rocks. Beavers are most active in the early morning and late evening, which seem to allow them to use areas near human use. Beavers do not appear to avoid areas of moderate to high levels of human use. Several occupied lodges in Yellowstone are close to popular backcountry trails and campsites. The first survey of beavers in the park, conducted in , reported 25 colonies, most of them cutting aspen trees. Although it was limited to parts of the northern range, comparing the locations of those beaver colonies with subsequent survey results demonstrates how beavers respond and contribute to changes in their habitat. A survey found eight colonies on the northern range, but none at the sites reported in and a lack of regrowth in cut aspen. Willow were also in decline during this period. To help restore the population of beavers on Gallatin National Forest, beavers were released into drainages north of the park from to Park-wide aerial surveys began in with a count of 49 colonies and increased to by ; dropping to in and in Some of the increase likely came from beavers dispersing from the national forest, but they would not have survived without suitable habitat. The increase has occurred throughout the park and is likely related to the resurgence in willow since the late s, at least on the northern range, and possibly in the park interior. Nearly all of the colonies documented in recent years were located in or near willow stands, none near aspen. Willow, which is more common in the park than aspen, is a hardier shrub that quickly regenerates after being clipped by beavers. The reason for the prolonged decline and relatively sudden release of willow on the northern range, and whether aspen have begun a sustained surge in recruitment, are topics of intense debate. Possible factors include the relationship of these plant species to changes in the abundance of beavers and elk, fire suppression, the reintroduction of wolves, and climate change.
