Aquatic Organism Passage Assessments

Audubon Society of Western Pennsylvania is evaluating 250 road-stream intersections to determine whether aquatic organisms and riparian species are able to reach necessary cooler headwaters. These cooler waters allow the organisms to carry out different life stages and prevent climate stress. In the past, most road-stream crossings were designed without consideration of the ecological process— the goal was just to move water away as fast as possible.




Our research will identify opportunities to restore biological corridors and maintain the integrity of Buffalo Creek’s High-Quality streams. The findings will be used to fundraise for the design and implementation of improved infrastructure in priority locations.
