State Protection: Endangered
listed species are those with: 1) 5 or fewer extant sites, or 2) fewer than 1,000 individuals, or 3) restricted to fewer than 4 U.S.G.S. 7 minute topographical maps, or 4) species listed as endangered by U.S. Department of Interior.

Federal Protection: Not Listed

State Rarity Rank: S1
A State Rarity Rank of S1 means: This plant is endangered/critically imperiled in New York because of extreme rarity (typically 5 or fewer populations or very few remaining individuals) or is extremely vulnerable to extirpation from New York due to biological factors.

Global Rarity Rank: G5
A Global Rarity Rank of G5 means: This species is demonstrably secure globally, though it may be quite rare in parts of its range, especially at the periphery.


Did you know?
The specific name cespitosum means forming tufts and is probably in reference to the way this species creates dense patches. Dwarf blueberry is a very widespread species, occurring as far away as the highlands of Guatemala, but it is very rare in New York.

State Ranking Justification [-]
There are two known populations. One of these populations has only one individual while the other has a few hundred. There are also four historical populations which have not been seen for over 40 years. Some of these historical populations have been looked for but more survey work is needed to determine if they have become extirpated.
