Management Plan
In the rain shadow of the Rocky Mountains, the Great Plains are dry, windy and expansive. Receiving small amounts of precipitation, the land is dominated by grasses. The scarcity of water generally prevents larger shrubs and trees from growing. The exception is where rivers, streams or ponds exist. In these riparian habitats plant and animal life is more diverse due to the presence of water. Trees, sedges and cattails grow and a variety of mammals, birds, amphibians, reptiles and insects are drawn to the water where temperatures are often slightly cooler than the surrounding lands.

The Name
Chief Niwot (c. 1825-1864) was a tribal leader of the Southern Arapaho people and played an important part in the history of Colorado. Chief Niwot and his people lived along the Front Range often wintering in Boulder Valley, site of the future city of Boulder.
The Trail
In April 2003, the Board of County Commissioners approved a list of 10 prioritized regional trail projects. The Longmont-Boulder Trail was among the top, consisting partly of the Niwot Loop Trail.
