Statewide Fen Mapping Completed
CDOT contracted with the Colorado Natural Heritage Program to complete statewide fen wetland mapping within and adjacent to CDOT rights-of-way. The field work and reporting was completed in July 2018.

Additionally, these data are uploaded to CDOT's OTIS site and can be found as a layer called "Potential Fen Wetlands". 

Please contact Becky Pierce with any questions concerning these data.
