Dicots |  Printer Friendly Version (PDF) |
Family: Pea Family (Fabaceae)
State Protection: Threatened 
listed species are those with: 1) 6 to fewer than 20 extant sites, or 2) 1,000 to fewer than 3,000 individuals, or 3) restricted to not less than 4 or more than 7 U.S.G.S. 7 ? minute topographical maps, or 4) listed as threatened by U.S. Department of the Interior. Federal Protection: Not Listed State Rarity Rank: S2
A State Rarity Rank of S2 means: This plant is threatened/imperiled in New York because of rarity (typically 6-20 populations or few remaining individuals) or is 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? Little-leaf Tick-trefoil has the shortest leaflets of any Desmodium in New York State. Historical records show the species occurring across the state south of the Adirondacks in open sandy areas, similar to the areas where blue lupine is found. It should be looked for where lupine has been seen. Presently it is known only from Long Island and the Syracuse and Rochester areas. |

| State Ranking Justification | [-] |
There are 16 existing populations, but only 3 of them have more than 100 plants, although the largest has more than 5000. There are 49 historical occurrencess and many have not been checked.
| Short-term Trends | [-] |
The larger populations seem stable, but three smaller populations were not rediscovered in recent surveys and most likely have been extirpated.
| Long-term Trends | [-] |
There are many historical records which have not been rechecked, so the true long-term trend is unknown. The larger populations will probably remain viable into the foreseeable future.
