The effects of artificial lighting on nesting female sea turtles and their offspring have been well documented in Florida for years. While federal and state regulatory agencies have pursued dark beaches to protect sea turtle habitat, Florida’s coastline has continued to develop and degrade nesting beaches with artificial light. Currently, Florida D...
Forest Managers are facing a series of problems that are making it difficult to effectively manage the vast national system of over 644,000km (400,000 miles) of forest roads and protect the environment. Current national funding levels are inadequate to maintain these roads to environmental and safety standards. With years of low maintenance budgets...
Transportation systems have been critical to the development of most societies. These systems form large networks and require large areas of land. Over the passage of time most transportation systems will continue to expand and technological advances will lead to new forms of transportation. Thus, our understanding of their effects on the environme...
Under the current Environmental Impact Statement (EIS) project development process, the Pennsylvania Department of Transportation (PENNDOT) typically develops engineering alternatives which are presented to the State and Federal resource agencies, local governmental organizations, and the public (these three groups are known as the project stakehol...
The Maryland Route 30 Bypass at Hampstead, Carroll County, Maryland is a long awaited 4.5 mile $27 million safety and congestion relief project proposed by the Maryland State Highway Administration (MD SHA). However, an unanticipated problem arose during the final stages of design and prior to the submittal of state and federal environmental permit...
Funding Source and Budget: Town of Amherst, New York. $60,000 Project Period: October 2000-September 2001 The Town of Amherst, New York is an urban/suburban community near Buffalo that has experienced considerable development in the past 10 years (1991-2000). In the same time period, the Town has experienced a noticeable increase in deer vehicle ac...
Transportation projects set within river valleys are susceptible to incurring economic and environmental costs when they fail to recognize and accommodate geomorphic processes. For example, overlooking natural processes such as channel migration can lead to costly protection measures that adversely impact aquatic habitat and further exasperate prob...
Vehicular traffic can be a major source of mortality for some species. Highly uagile organisms may be at a disadvantage in landscapes with roads because they are more likely to encounter roads and incur traffic mortality. To test this prediction, we assessed the population abundance of two anuran species of differing vagility, the leopard frog (Ran...
Managed baselevel lowering in tributaries that emerge from small canyons onto forested floodplains affects floodplain and fan sediment storage and small ephemeral tributary channel morphology in the Navarro River basin, Mendocino Country, California, USA. Numerous small tributaries (drainage areas up to several square kilometres) flow through culve...
Conventional wisdom and highway practice across many states seemed to suggest that high (~2.4 m) ‘deer-proof’ fencing, coupled with underpasses are the mitigation of choice to prevent deer (and other ungulate) mortalities on U.S. highways. Our observations here in Utah and those elsewhere in the U.S. strongly suggested that few, if any, so called ‘...
