The Pikes Peak Area Council of Governments Moving Forward metropolitan transportation planning process introduced a Strategic assessment planning framework to the Pikes Peak region. This framework was selected because it integrates multi-disciplinary qualitative and quantitative information from technical experts and regional stakeholders to determ...
Large anthropogenic infrastructure such as major bridges in and near waterways can influence the ecological dynamics of the nearby aquatic environment. These influences may affect behavior, habitat use, fitness, and survival of fishes. Chinook salmon (Oncoryhnchus tshawytscha) spawning in tributaries to Lake Washington typically spend three to five...
Climate change in the Pacific Northwest of America is likely to bring more frequent, heavier winter precipitation as temperature rises. These changes in precipitation patterns have significant implications in hydrology and socioeconomic sectors that could be affected by changes in hydrology. Transportation infrastructure and travel patterns are als...
In the 1900‘s, the badger population of the Netherlands was estimated to count 2500 to 3000 setts with over 4000 individuals. Between then and the 1960‘s, the number declined drastically and stayed low until the mid-1980‘s with about 400 setts in the whole of the Netherlands. In the 1980‘s a high percentage of the population, locally up to 25%, was...
Road damage caused by beavers is a costly problem for transportation departments in the U.S. Population control and dam destruction are the most widely used methods to reduce road damage caused by beavers, but the benefits of such measures in some situations are often very short-term. At chronic damage sites, it may be more effective and cost-benef...
The development of infrastructure facilities can negatively impact critical habitat and essential ecosystems. There are a variety of techniques available to avoid, minimize, and mitigate negative impacts of existing infrastructure as well as future infrastructure development. However, such techniques may not always provide the greatest environmenta...
Stormwater conveyance practices are grounded in industrial design that neglects integration with system processes, economics, and aesthetics. As a result, the greater volume of runoff from impervious surfaces, coupled with smooth and hardened conveyance systems (e.g., pipes and trapezoidal concrete channels), magnifies and transfers energies to the...
Protecting habitat connectivity for wildlife is a management imperative facing agencies and wildlife organizations across the United States. To maintain connectivity and improve highway safety across transportation routes in western Montana, American Wildlands conducted a rapid wildlife linkage and highway safety assessment. This analysis had two p...
Centralized planning framework, accelerating habitat fragmentation and growing awareness to animal-transportation issues in Israel have lead to increased demand for ecological considerations during road construction and maintenance. Several governmental bodies have upgraded their requests regarding fauna passages and monitoring, with substantial bu...
Based on an analysis of current literature, we developed a Traffic Volume Wildlife Tool that identifies different levels of traffic volume as a means to assess risk to various wildlife species groups, including amphibians, reptiles, birds, and mammals. Each level includes an assessment of when impacts to different species groups begin and when they...
