Map of wood-filled areas in the United States, c. 2000 [1] In the United States , the forest cover by state and territory is estimated from tree-attributes using the basic statistics reported by the Forest Inventory and Analysis (FIA) program of the Forest Service . [ 2 ]
Poa pratensis, commonly known as Kentucky bluegrass (or blue grass), smooth meadow-grass, or common meadow-grass, is a perennial species of grass native to practically all of Europe, North Asia and the mountains of Algeria and Morocco.
Before European-American settlement, various cultures of Indigenous peoples of the Americas lived in the region. The pre-colonization state of the Bluegrass is poorly known, but it is thought to have been a type of savannah known as oak savanna, with open grassland containing clover, giant river cane (a type of bamboo), and scattered enormous trees, primarily bur oak, blue ash, Shumard's oak ...
The cultivar Zoysia 'Emerald' (Emerald Zoysia), a hybrid between Z. japonica and Z. tenuifolia, [13] is particularly popular. Some types of zoysia are available commercially as sod in some areas. In typical savanna climates with warm wet and dry seasons, such as southern Florida , zoysia grasses grow during the warm-wet summer and are dormant ...
During the 1990s, botanists began experimenting with producing hybrids of Texas bluegrass and Kentucky bluegrass (Poa pratensis) for use as wintering foraging plant for grazing livestock [citation needed] and as a drought-resistant lawn grass. The hybrids appear similar to Kentucky bluegrass, but maintain their green color in higher ...
Forests were particularly common in the uplands of the Inner Bluegrass region of Kentucky, which has naturally mesic conditions. These forests were dominated by sugar maple ( Acer saccharum ), bitternut hickory ( Carya cordiformis ), Ohio buckleye ( Aesculus glabra ), blue ash ( Fraxinus quadrangulata ), and chinquapin oak ( Quercus muhlenbergii ).
In terms of biodiversity, the only comparable temperate deciduous forest regions in the world are in central China, Japan, and in the Caucasus Mountains.Both the Appalachians (along with the neighbouring Appalachian mixed mesophytic forests ecoregion) and central China contain relict habitats of an ancient forest that was once widespread over the Northern Hemisphere.
