Roads have become an integral part of our society, but recently society has begun to realize the ecological impact that roads have on their surroundings. One major effect that roads have on large mammals is creating a barrier to movement of individuals both between and within populations. In an effort to alleviate this problem on a new interstate p...
The State of Florida has developed a new process for accomplishing transportation planning and project development for major capacity improvement projects. The goal of this process – the Efficient Transportation Decision Making (ETDM) Process - is to make transportation decisions more quickly without sacrificing the quality of the human and natural...

Freshwater ecosystems are vital for human well-being and ecological integrity but are increasingly jeopardized by habitat loss and degradation, fragmentation, water abstraction, and climate change. These threats are diverse and pervasive and thus require new thinking about conservation problems and solutions. Here, we describe the Society for Conse...

Transportation planners occasionally notice a curious lack of consistency and communication between hydrologists, fisheries biologists and wildlife biologists regarding passages designed for their respective specialties. Several substantial differences in treatments between aquatic and terrestrial passages at highways masks the majority of similari...
Protected wildlife species that utilize the Washington State Department of Transportation (WSDOT) bridges and structures may be susceptible to impacts from routine maintenance and inspection activities. In response to community-driven concerns related to the conservation of protected terrestrial species and due to the lack of existing guidance for ...

The connectivity of river drainages has been decreased by the installation of roadway culverts, particularly for the salmonids of the Pacific Northwest. Thousands of culverts within the State of Washington have been designated by the state DOT as fish passage barriers. Though it is well known that the anadromous salmon travel upstream to spawn, rec...
Mulkey, Inc. is participating in a stream restoration study with the Ecosystem Enhancement Program in Yadkin County, North Carolina. The purpose of this study is to restore approximately 4,300 linear feet of Rocky Branch, a second order stream locatedin the western Piedmont of North Carolina. Stream restoration in North Carolina is generally conduc...
Seasonal movements are fundamental to the life cycles of many species of amphibians and reptiles. These patterns of migration can be compromised by the presence of roads. Roads negatively impact many amphibian and reptile populations in various ways, such as obstructing movement, fragmenting and degrading habitats and causing increased mortality th...
Revegetation is an essential component of roadside and building site construction and improvement. In the southern United States non-native grass species are frequently included in revegetation seed mixes used by highway authorities. Non-native species are frequently selected for aggressive growth characteristics, however these same traits also ren...
Artificial lighting has two important effects on sea turtles: It reduces the attractiveness of the beach to nesting females, and thus decreases the number of turtles which place nests in a coastal region, and; it interferes with the hatchlings ability to orient normally from the nest to the ocean. Both of these effects depend upon the overall inten...
