Midland Sedge
Carex mesochorea Mackenzie
Monocots
Carex mesochorea Stephen M. Young
Family: Sedge Family (Cyperaceae)

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 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: G4G5
A Global Rarity Rank of G4G5 means: Apparently or Demonstrably Secure globally - Uncommon to common in the world, but not rare; usually widespread, but may be rare in some parts of its range; possibly some cause for long-term concern due to declines or other factors. More information is needed to assign a single conservation status.


Did you know?
Humans may be contributing to the increased abundance of this sedge since one of the habitats it seems to prefer is abandoned fire pits. The specific name means midland and refers to its range.

State Ranking Justification [-]
There are currently eight known populations of this relatively new arrival to New York State. At this time, we consider the presence of the sedge as the natural range extension of a sedge native to the Midwest. If this plant continues to spread, we may find new populations elsewhere within the state. Few threats are reported. This sedge seems to withstand fire and mowing, so it is rather resilient.
