Species distribution modeling is one of many tools available to assist managers in understanding the potential distribution of rare and endemic species when regulating and prioritizing different land-use scenarios. Developing a predictive model of the distribution of a particular species can involve several different techniques, and be reported under a variety of names. In this study we used an iterative modeling approach to investigate the potential distribution of two rare species: Physaria (Lesquerella) congesta (Dudley Bluffs Bladderpod), and Physaria obcordata (Piceance twinpod).
The purpose of the Wetlands Program Book is to document critical information needed to implement the Colorado Department of Transportation's (CDOT) Wetlands Program. The mission of CDOT's Wetlands Program is to provide technical assistance for transportation project development and construction in order to minimize potential negative impacts to the state's wetlands and aquatic ecosystems.
The FACWet was developed by surveying existing wetland rapid assessment methodologies and blending the best aspects these approaches with the most recent advances in wetland science.
The purpose of this Manual is to provide guidance on preparing and processing documents that comply with NEPA and other applicable state and federal environmental laws affecting transportation projects in Colorado. This Manual provides references and links to related federal and state laws, executive orders, regulations, and policies. It also provides "best practice" examples for various compliance processes where appropriate. It is intended that CDOT staff, local agency representatives, and consultants use this Manual to implement NEPA in an effective manner, producing more consistent, improved environmental documents that decision-makers may use to make well-informed transportation decisions.
