Wildlife and Roads

UTCFWRU

This initial step is the first in a process of evaluating ecological and transportation considerations to determine if wildlife mitigation may be needed. Explanations and related website links are provided for users unfamiliar with the transportation planning process. If further action is required after this step, further steps are outlined with methodology to identify goals and objectives of the mitigation.

1.1 Identify Scope of Transportation Plan/Project: In this very first step users will determine the spatial and temporal (time) extent of the proposed transportation program or project and the information resources necessary to help predict potential effects of the plan/project.

1.2 Identify Wildlife & Fisheries Issues: We direct the users to a series of steps which first provide a literature base on the effects of roads, and the need for permeability for wildlife. The guide then instructs the user in identifying the species, natural areas, and natural processes that may be affected by the plan/project. At the end of this step, the user will decide if there is a need for mitigation and whether to proceed with the decision guide.

1.3 Identify Goals & Objectives: If the user has decided from the first two steps that there is a need to mitigate for wildlife, then the potential effects of the plan/project are listed and the possible solutions and the goals of those solutions are developed here. Users will define performance measures or goals of mitigation and identify methods to evaluate how those goals are met over the long term.
