International Vegetation Classification Associations [-]
This New York natural community encompasses all or part of the concept of the following International Vegetation Classification (IVC) natural community associations. These are often described at finer resolution than New York's natural communities. The IVC is developed and maintained by NatureServe.


NatureServe Ecological Systems [-]
This New York natural community falls into the following ecological system(s). Ecological systems are often described at a coarser resolution than New York's natural communities and tend to represent clusters of associations found in similar environments. The ecological systems project is developed and maintained by NatureServe.

Percent Cover
This figure helps visualize the structure and 'look' or 'feel' of a typical Calcareous Pavement Barrens. Each bar represents the amount of 'coverage' for all the species growing at that height. Because layers overlap (shrubs may grow under trees, for example), the shaded regions can add up to more than 100%.
