Full Species List of Grasses, Sedges & Rushes

Collectively referred to as graminoids, grass and the grass-like 

(sedges and rushes) species account for 13% of the vascular plants 

within Shenandoah National Park and are found in a variety of 

habitats. While typically associated with open areas such as 

meadows and lawns, graminoids can also be found in forest 

ecosystems. Despite their relative abundance, these species are 

often overlooked because of their small wind-pollinated flowers 

and nondescript linear leaves. The largest threat to native 

grasses, sedges, and rushes within the park is the proliferation of 

exotic plants, particularly non-native Eurasian grass species. 

In Shenandoah National Park grasses can be easily viewed at Big 

Meadows where colonial bent grass (Agrostis capillaris) and tall 

oatgrass (Arrhenatherum elatius) are especially abundant. The 

troublesome invasive species Japanese stiltgrass (Microstegium

vimineum) can be seen throughout the Elkwallow picnic area 

where it is has displaced nearly all other forest understory plants.

This checklist was compiled on March 10, 2015 using data 

exported from the National Park Service NPSpecies database. The 

database can be accessed at https://irma.nps.gov/NPSpecies/.

Here you will find search tools that make it possible to create 

updated or customized lists. This checklist and others are found 

at https://irma.nps.gov/NPSpecies/Search/SpeciesList/SHEN. Lists 

are currently available for the following: mammals, birds, fish, 

reptiles, amphibians, butterflies, plants (complete list), trees and 

shrubs, wildflowers, ferns, and grasses. Please be advised that 

Latin scientific names often change as a result of new research; 

therefore, scientific names used here may not reflect the most 

current accepted nomenclature.

Occurrence (Occ) P Present Species occurs in park; current, reliable evidence available.

PP Probably Present High confidence species occurs in park but current, verified evidence needed.

Un Unconfirmed Species is attributed to park but evidence is weak or absent.

NP Not In Park Species is not known to occur in park.

Abundance (Abd) A Abundant Animals: May be seen daily, in suitable habitat and season, and counted in 

relatively large numbers. Plants, Chromista, Protozoa, and Fungi: Large number 

of individuals; wide ecological amplitude or occurring in habitats covering a large 

portion of the park

C Common Animals: May be seen daily, in suitable habitat and season, but not in large
