Quick Answer
Short Answer: Tree well shelters can attract wildlife such as wolverines, mountain goats, and grizzly bears due to their natural protection and potentially abundant food sources. These shelters are often found in mountainous regions with limited vegetation, making them a valuable resource for wildlife. The presence of water sources nearby can further increase the likelihood of wildlife presence.
Types of Wildlife Attracted
Tree well shelters are often used by large mammals, such as grizzly bears, that require a high caloric intake to survive the harsh winter months. These bears can be found in tree wells with a depth of 10-15 feet and a diameter of 50-100 feet. They typically use these shelters from November to February, when food sources are scarce.
Habitat Requirements
Wolverines and mountain goats also frequent tree well shelters, particularly those with steep slopes and limited vegetation. These areas provide the wolverines with access to food sources such as small mammals and carrion, while mountain goats use the shelters to escape harsh weather conditions. A minimum tree well diameter of 50 feet is recommended for these species.
Seasonal Patterns
The use of tree well shelters by wildlife varies depending on the species and the season. Grizzly bears typically use these shelters during the winter months, while wolverines and mountain goats use them throughout the year. Tree wells with a depth of 15-20 feet and a diameter of 100-150 feet are more likely to be used by these species, especially during periods of extreme weather.
