Elymus glaucus ssp. glaucus

Habitat [-]
The site where Elymus glaucus ssp. glaucus occurs in New York is a pitch pine oak heath rocky summit natural community. The plants occur near the top of an east-facing ridge, between 1700 and 1800 feet in elevation. There are areas of oak and pine forest as well as ledges and rocky outcrops dominated by grasses and sedges (New York Natural Heritage Program 2009).

Associated Ecological Communities [-]
  • Pitch pine-oak-heath rocky summit
    A community that occurs on warm, dry, rocky ridgetops and summits where the bedrock is non-calcareous (such as quartzite, sandstone, or schist), and the soils are more or less acidic. This community is broadly defined and includes examples that may lack pines and are dominated by scrub oak and/or heath shrubs apparently related to fire regime.
  • Pitch pine-oak-heath woodland*
    A pine barrens community that occurs on well-drained, infertile, sandy soils. The structure of this community is intermediate between a shrub-savanna and a woodland. Pitch pine and white oak are the most abundant trees.
