Colorado Wetland Plant Field Guide List

Vegetation is often the most conspicuous component in a wetland and often defines the wetland type. A commonly used term for a wetland plant is a hydrophyte: a plant that grows in water or on a substrate that is at least periodically deficient in oxygen as a result of excessive water content.

The National Wetland Plant List is a common classification system for hydrophytic plant species. The List uses on a five-tiered wetland indicator status rating system to describe the likelihood a plant occurs in wetlands as opposed to non-wetlands. Each species on the list is rating independently for ten geographic regions within the United States and outlying territories, three of which occur within Colorado: Arid West (AW), Western Mountains Valleys and Coast (WMVC), and Great Plains (GP).

Wetland indicator status ratings

Indicator Code Indicator Status Comment
OBL Obligate Wetland Almost always occurs in wetlands.
FACW Facultative Wetland Usually occurs in wetlands, but may occur in non-wetlands.
FAC Facultative Occurs in wetlands and non-wetlands.
FACU Facultative Upland Usually occurs in non-wetlands, but may occur in wetlands.
UPL Obligate Upland Almost never occurs in wetlands.
NI No Indicator Insufficient information available to determine indicator status

National Wetland Plant List Regions in Colorado


The Field Guide to Colorado’s Wetland Plants includes detailed information on over 600 plants on the National Wetland Plant List, with an emphasis on species rated OBL or FACW. Below is a list of all species included in the Field Guide, and their wetland indicator status. For a complete list of wetland plants in Colorado, see the National Wetland Plant List website.
