Impact of human induced disturbances on wildlife communities

Habitat improvements intended to benefit one or two species may differentially affect other species within or near the same area. These habitat improvements are generally in the form of mechanical disturbance, such as forest thinning, mastication, or chaining. Yet, the effects of these restoration techniques on non-target wildlife are not well understood. I have been investigating the long term and short term effects of mechanical disturbance on bird and mammal communities. Most of this research has been conducted in the Piceance Basin of Northwest Colorado where land managers are currently enacting habitat manipulation efforts to improve habitat for mule deer and sage grouse. However, I am generally interested in how habitat improvement and restoration efforts affect wildlife populations and communities.
