EXECUTIVE SUMMARY State and federal highways in Colorado stretch from the eastern plains to the Continental divide and the canyons and plateaus of western Colorado, and range in elevation from 3,369 ft (1,027 m) to 14,130 ft (4,307 m). As highways cross Colorado’s many mountain passes, they intersect watersheds rich in fen wetlands. Fens are wetlands with organics soil, which have formed over thousands of years. These wetlands are an irreplaceable resource that support high biodiversity, sequester carbon, and support regional hydrology. The Colorado Department of Transportation (CDOT) has determined that road construction and maintenance should avoid fen wetlands whenever practicable. Efficient implementation of this policy, however, has been hindered by a lack of comprehensive information on fens surrounding the Colorado highway network.
