Rich Graminoid Fen |
 Printer Friendly Version (PDF) |
System: Palustrine
SubSystem: Open Peatlands State Protection: Not Listed Federal Protection: Not Listed State Rarity Rank: S1 
A State Rarity Rank of S1 means: Typically 5 or fewer occurrences, very few remaining individuals, acres, or miles of stream, or some factor of its biology makes it especially vulnerable in New York State. Global Rarity Rank: G3
A Global Rarity Rank of G3 means: Either rare and local throughout its range (21 to 100 occurrences), or found locally (even abundantly at some of its locations) in a restricted range (e.g. a physiographic region), or vulnerable to extinction throughout its range because of other factors. Did you know? "Rich" in rich graminoid fen refers to the position of this community on the pH and minerotrophic scales. It has a relatively high pH and groundwater nutrient availability. Rich graminoid fens are also high in plant diversity compared to bogs and poor fens, often having dozens of plant species growing within a 10 m x 10 m sample area. |

| State Ranking Justification | [-] |
There are only about fifty occurrences statewide, and the total acreage is very small. Some documented occurrences have good viability and a few are protected on public land or private conservation land. This community is limited to the calcareous areas of the state, and includes a few high quality examples. The current trend of this community is probably stable for occurrences on public land, or declining slightly elsewhere due to moderate threats related to development pressure, invasive plants, and alteration to the natural hydrology.
| Short-term Trends | [-] |
The number and acreage of rich graminoid fens in New York have probably remained stable in recent decades as a result of wetland protection regulations.
| Long-term Trends | [-] |
The number and acreage of rich graminoid fens in New York have probably declined moderately to substantially from historical numbers, likely correlated with the onset of agricultural and residential development.
