This directly impacts the habitat of these species, and many signature fen species disappear. [4] Fens are also threatened by invasive species, fragmentation, peat cutting, and pollution. [5] Non-native invasive species, such as the common buckthorn in North America, can invade fens and outcompete rare fen species, reducing biodiversity. [5]
Arboreal species are widely found in the region due to the high density of tree cover, providing a suitable habitat and food source for the animals; this includes birds and many ground squirrels. Migratory songbirds are common in the eastern temperate forests once the canopy opens up in the spring.
Platanthera leucophaea, commonly known as the prairie white fringed orchid [6] or eastern prairie fringed orchid, is a rare species of orchid native to North America. It is a federally threatened species, [ 7 ] protected since October 30, 1989 under the Endangered Species Act of 1973 . [ 8 ]
Federally threatened plant species: Prairie bush-clover (Lespedeza leptostachya) Mead's milkweed (Asclepias meadii) Northern wild monkshood (Aconitum noveboracense) Eastern prairie fringed orchid (Platanthera leucophaea) Western prairie fringed orchid (Platanthera praeclara) Extinct animal species (historical): [9]
The species is found along forest edges, rock piles, and rotting logs or stumps in the eastern United States. It is sometimes referred to as the prairie lizard, fence swift, gray lizard, gravid lizard, northern fence lizard or pine lizard. [4] It is also referred to colloquially as the horn-billed lizard.
The ecosystem of over 98% of eastern woodland areas such as longleaf pine have declined. [12] Remaining grassy woodland and prairie cover some of the land in the following locations: Grand Bay National Wildlife Refuge, Alabama [8] Old Cahawba Prairie, Alabama [13] Apalachicola National Forest, Florida [8] Garcon Point, Florida [8]
The refuge is on the eastern edge of the tallgrass prairie region of the Northern Great Plains, an area known for its agriculture. This 3,334-acre (13.49 km 2) refuge surrounded by a sea of corn and soybeans provides vital habitat for a variety of plants and animals dependent upon tallgrass prairie and wetland habitats.
Historic (and modern) loss of habitat, as well as overharvesting, has affected some native mammals to the point of extirpation, including the bison (disappeared in the mid-1800s; the last bison was reported in southwest Minnesota in 1879; [5] a non-wild population exists in Blue Mounds State Park [6]), cougar (though vagrant individuals are ...
