Poa compressa often occurs in disturbed areas and seems to require disturbance to establish. However, it also occurs in communities of conservation concern including prairies, alvar grasslands, granite barrens, and ridgetop woodlands. More information about its impact on native species is needed. Apparently, it has more impacts in the northern portion of its range. Poa compressa has agressive reproductive characters and may crowd out native species. It has creeping rhizomes and can forms large colonies. It can spread very quickly because it grows early in the season when most other species are dormant . The presence of Poa compressa may also affect the community composition due to its response to various fire regimes. Poa compressa is often considered with Poa pratensis so it can be difficult to determine the impact of Poa compressa alone in some areas. Control is apparently difficult. Eradication of bluegrass in northern mixed prairies of the midwest or wet meadows of the Pacific Northwest may be infesaible. Reduction of vigor and containment of spread may be the only realistic management goals. More information is needed, especially from the southern portion of its range. This plant is a invasive in agricultural areas, but not likely to be a pest in natural areas in the OBRI region (RE 2007).
