Quiet Wildlife Underpasses
Many wildlife underpasses are noisy and frighten animals away. Research needs to be done to find a way to make thes structures (bridges, box culvers, steel arch culverts, conspan arches,…

The threats to human safety posed by high rates of large mammal road-kill are well reported in the literature, as well as the adverse effects of road-kill on mammal populations;…
An overall assessment of fish passage conditions from headwaters to estuaries requires the analysis of the entire channel network connecting those habitats. Such an analysis should not be performed in…
Scope: Research Objectives: The Clean Water Act, Endangered Species Act, and National Forest Management Act require that stream-road crossings are designed such that viable populations of native aquatic species are…
Scope: (1) Objectives. The objective of our proposed scope of research is to research and develop professional activities aimed at incorporating wildlife mitigation into standardized federal and state highway planning and…
The southeastern United States is the center of biodiversity for freshwater fishes and mussels in North America. Many of these species are imperiled and one of the leading causes of imperilment…
Bridges built in previous decades often incorporated expansion joints that provided optimal roosting habitat for bats. This is due to the combination of favorable gap size, open canopy in road…
The objective of this research is to develop a PDA that obtains the matrices identified for structures, habitats and species so that field personnel will have a tool for assessing…
Objective- To show that in most cases that the IPAC system is greatly flawed and the most states have far more accurate data in their own GIS Systems.The best available…
Problem Statement: Large animal-vehicle collisions are a growing problem nationwide and results in fatalities, personal injuries, and property damage. While “road-kill” data is collected, the nation needs to quantify the extent…
