State Rarity Rank: S1
A State Rarity Rank of S1 means: Typically 5 or fewer occurrences, very few remaining individuals, acres, or miles of stream, or some factor of its biology makes it especially vulnerable in New York State.

Global Rarity Rank: G1G2
A Global Rarity Rank of G1G2 means: Critically Imperiled or Imperiled globally - At very high or high risk of extinction due to rarity or other factors; typically 20 or fewer populations or locations in the world, very few individuals, very restricted range, few remaining acres (or miles of stream), and/or steep declines. More information is needed to assign a single conservation status.


Did you know?
Eastern red cedar (Juniperus virginiana) is dioecious. This means that some trees are female and some trees are male. The male trees have pollen-producing flowers and the female trees produce the familiar light blue "juniper berries." These "berries" are technically cones with fleshy blue scales and a white waxy cover, giving the them an overall sky-blue color. They are a favorite food of cedar waxwings and other birds, which disperse the seeds to other locations.

State Ranking Justification [-]
There are very few occurrences of this community in New York. One documented occurrence has fair viability and is protected on private conservation land. In New York, calcareous red cedar barrens are apparently strongly correlated with the presence of Stockbridge Marble bedrock and the Farmington-Rock soil unit. There are no large, high quality examples known in the state. The current trend of this community is probably stable for the one occurrence on private conservation land, and very likely declining elsewhere due to moderate threats related to fire suppression, invasive species, and development pressure.
