Mapping
If a picture is worth a thousand words, a map can readily convey the story of a thousand data points. Accurate and precise mapping of natural resources, in easy-to-access geospatial datasets, is essential for coordinated, effective management. CNHP is known for its high quality map products, from rare and imperiled species to land ownership to vegetation and wetland maps.
CNHP's element occurrence map has tens of thousands of locations of rare and imperiled species and natural plant communties.
Total Number of Mapped Locations [Last Updated: September, 2025 ]
- Animals: 23,177
- Plants: 29,179
- Natural Plant Communities: 5,264

Colorado Wetland Inventory Mapping Tool
Information on the location, extent and type of wetlands in Colorado allows land managers and state agencies to make informed decisions about wetland resources. CNHP’s Colorado Wetland Inventory mapping tool shows detailed wetland mapping created by the CNHP, U.S. Fish and Wildlife Service’s National Wetland Inventory (NWI) program, and several other partners.

Fen Mapping
Fens are groundwater-fed wetlands with organic soils that typically support sedges and low stature shrubs. In the mountain west, organic soil formation can take thousands of years. Given the sensitivity of fens, they are a high priority for conservation and restoration. CNHP has developed a particular expertise for mapping fen wetlands using aerial imagery and ancillary data sources.

Noxious Weed Inventory, Mapping and Monitoring
Many of Colorado’s native landscapes have been altered by the arrival of plants from other regions of the globe. Maps of invasive plants and long-term monitoring are critical for effective management and protection of native communities. CNHP conducts surveys to inventory, map and monitor noxious weeds across Colorado.
