Abstract

Anthropogenic noise is a burgeoning issue for national parks. Acoustical monitorng has revealed chronic noise exposure even in remote wilderness sites. Increased noise levels significantly reduce the distance and area over which acoustic signals can be sensed by an animal receiver. A borad range of research findings indicates the potential severity of this threat to diverse taxa, and recent studies document substantial changes in behavior, breeding success, density and community structure in response to noise. Ansalysis of these data make a compelling case for systemic efforts to preserve acoustic environments throughout the National Park System.
