Do Ruffed Grouse Prefer Certain Types of Aspen Trees?

Aspen Habitat Characteristics

Ruffed grouse are highly dependent on aspen (Populus tremuloides) trees for their survival. They prefer aspen stands with dense undergrowth, typically 1-10 years old, which provide an abundance of food and cover. In these young aspen stands, grouse can find an array of edible plants, including grasses, shrubs, and forbs.

Foraging and Nesting Habitat

Ruffed grouse use aspen stands for foraging, especially during the spring and summer months. They feed on the leaves, buds, and twigs of aspen trees, as well as insects and other invertebrates. Grouse also use aspen stands for nesting, with females typically selecting a location with dense cover and an abundance of leaf litter. When selecting a nesting site, female grouse often choose an aspen stand with trees spaced 1-3 feet apart.

Management Recommendations

To create or maintain ruffed grouse habitat in aspen stands, land managers should consider the following techniques. First, avoid clear-cutting or logging aspen stands, as this can destroy the dense undergrowth and leaf litter that grouse rely on. Instead, consider selective logging or thinning, which can help maintain the desired age and density of aspen trees. Second, consider establishing a burn program, which can help promote the growth of young aspen saplings and maintain the open, park-like conditions preferred by ruffed grouse.
