Devils Tower National Monument rides high on the plains of northwestern Wyoming.

Within the 1,347 acre park we find a myriad of different habitats, the ponderosa pine forest that surrounds the tower, the floodplain that surrounds the Belle Fourche River, and the grassland on the plains. Within these habitats there are thousands of plant species that populate Devils Tower National Monument.

Established in 1906, the monument preserves and protects its ecosystem and geologic features for scientific study and public enjoyment. These habitats and the plant species within them all are dependent upon the geologic, ecologic and human factors that shape the ecosystem within our boundaries.

Documented within our borders are more than 500 native and non-native plant species that provide homes and food for our wildlife, prevent erosion of our soils and provide beauty for our eyes.

Native Plants
A comprehensive list of the wildflowers most often seen along our trails and roads.

Non-Native Plants
Invasive non-native plants can displace native plant species, change the makeup of vegetation communities and affect the frequency of fire and the distribution, foraging activity, and abundance of wildlife. We are working to remove these non-native species and encourage native plant communities.

A Scientific Opportunity

Have you ever taken a picture of a deer, lizard, or unusual plant? Through a mobile and web-based tool called iNaturalist**, you can now share your photographs online, and people all over the world can help identify your observations. Together, people everywhere will be helping to create a record of life in our parks.

Anyone visiting national park lands with a smartphone or digital camera can turn their photos of plants, animals, fungi, and other “critters” into useful data. Even if participants don’t know exactly which species they recorded, members of the global iNaturalist community work together to crowdsource identifications. Verified records from iNaturalist can be used to update NPSpecies, the official NPS database that documents our knowledge of the occurrence and status of species within each park.

What is NPSpecies?

NPSpecies is a web-based tool for documenting the occurrence and status of species in national parks. NPSpecies gives parks a way to build, manage, maintain, and share park species lists. As part of the IRMA Portal (Integrated Resource Management Applications), NPSpecies can be accessed at

Much of the data currently in NPSpecies has been entered by Inventory & Monitoring Program networks. Sources of information include species inventories, monitoring projects, reports, publications, and museum collections. NPSpecies users can also submit suggestions on list additions or updates.

NPSpecies is always a work in progress. Lists continue to change and improve as we learn more about species in parks. Some species categories such as birds or mammals have had extensive research done and their information in NPSpecies is relatively stable. Other categories such as invertebrates or non-vascular plants are less well known, and information in NPSpecies may be missing or in the early stages of development.

Paperwork Reduction and Privacy Act Statement: The National Park Service is authorized by 54 U.S.C. 100702 to collect this information. This information will be collected through iNaturalist during BioBlitzes and other NPS citizen science events. The purpose is to find and identify as many species of plants, animals, and other organisms as possible in or around National Parks so that these occurrences can be documented. The data will be used by the NPS to better understand which species occur on its lands and where those species occur. Response to this request is voluntary. No action may be taken against you for refusing to supply the information requested. The permanent data will be anonymous. An agency may not conduct or sponsor, and a person is not required to respond to, a collection of information unless it displays a currently valid OMB control number.
