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?
Rough-leaved dogwood is popular in the horticulture trade where an understory tree or shrub is needed for areas where other flowering trees may not do well because of dry or poor soil. Its habit of producing a dense clone provides cover for birds who are also attracted by its white, juicy fruits. The species is named for Thomas Drummond (1790-1835), a Scottish naturalist and plant explorer who made many plant collections in the United States from 1825-1835.

State Ranking Justification [-]
Currently there are only three known populations in the watershed of Cattaraugus Creek but trends are stable and threats are low. Only one populations is large. Three historical populations have been recorded in the same watershed so this species has always been rare within New York and will likely continue as just a few populations near the state's western border.
