Abstract: This layer represents a potential habitat model for the Olive-sided flycatcher (Contopus borealis) in Pennsylvania. The model associates occurrence of suitable habitat with key environmental factors that can be mapped over the entire region. These key factors include vegetative land cover, presence of human activity, elevation, topographic position, wetland characteristics and stream size and proximity. Areas of potential species presence were tabulated based on current and historical information and a series of conditional statements proceeded using layers derived to depict the key factors on a landscape scale.
Purpose: The PA Gap Analysis habitat models are compared in a collective manner to the distribution and extent of lands serving long-term conservation purposes. Mismatches of a substantial and extensive nature are identified as broad-scale "gaps" in the conservation safety net. Gap analysis is a "coarse filter" geographic approach to conservation, and is meant to supplement rather than supplant detailed work on a site level for species of special concern.
