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: G5T5?
A Global Rarity Rank of G5T5? means: Secure globally (most likely) - Conservation status of the subspecies/variety is uncertain, but is most likely common in the world; widespread and abundant (but may be rare in some parts of its range). More information is needed to assign a firm conservation status. (The species as a whole is common globally.)


Did you know?
Although very rare in northern New York, this plant occurs around the world in northern arctic regions. The name Lapland refers to northern Scandinavia where the species is relatively common. It is by far the smallest species of Rhododendron in New York.

State Ranking Justification [-]
There are 8 extant populations which all occur only on the highest peaks of the Adirondacks over a very small range. At least three of the populations are very small in number and many are at least somewhat threatened by hiker trampling.
