Family: Grass Family (Poaceae)
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 - Both the species as a whole and the subspecies/variety are common in the world; widespread and abundant (but may be rare in some parts of its range). Did you know? Side-oats grama is a very widespread and common grass west of New York but only occurs here in fewer than ten places. Many of them are close to or along current or historical railroad lines. It is one of the most beautiful and easy-to-recognize grasses in New York. |

| State Ranking Justification | [-] |
There are eight existing populations, half of them good or excellent. The other half are small or under threat. There are about 10 historical populations and most of those are probably extirpated.
| Short-term Trends | [-] |
The short-term trend appears good as most current populations have have not changed in size over the last 30 years.
| Long-term Trends | [-] |
The long-term trend has been somewhat negative as many of the historical populations in the Hudson River Valley have not been found again. This was a result of habitat succession and the introduction of weedy species through the suppression of fire and other human disturbances.
