California's coastal prairies are the most species-rich grassland types in North America, with up to 26 species present per square meter. [1] They have been described in literature as "previously unrecognized biodiversity hotspots," and are also known to provide an array of essential services—for instance, carbon storage, water filtration, agriculture, and livestock farming.

The tallgrass prairie ecosystem covered some 170 million acres (690,000 km 2) of North America. Besides agriculture, much of the shortgrass prairie became grazing land for domestic livestock . Short grasslands occur in semi-arid climates while tall grasslands are in areas of higher rainfall.
This can make the fen more ombrotrophic (dependent on precipitation), which results in acidification and a change in water chemistry. [4] 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]
The Alkali Sink Ecological Reserve is a protected conservation area spanning approximately 930 acres in the Central Valley of California. The reserve contains a variety of habitats, such as alkali sink scrub and annual grasslands, and serves as an essential refuge for numerous migratory birds, waterfowl, and endangered species.
The California condor is a critically endangered species, with only 350 left “and a significant piece of that population lives in ground zero of where these fires have happened,” Corwin noted.
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 ]
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 forests of Northern California are home to many animals, for instance the American black bear.There are between 25,000 and 35,000 black bears in the state. [6]The forests in northern parts of California have an abundant fauna, which includes for instance the black-tailed deer, black bear, gray fox, North American cougar, bobcat, and Roosevelt elk.
