Sandhill
A sandhill is a type of ecological community or xeric wildfire-maintained ecosystem. It is not the same as a sand dune. It features very short fire return intervals, one to five years. Without fire, sandhills undergo ecological succession and become more oak dominated. Entisols are the typical sandhill soil, deep well-drained and nutrient poor. In Florida, sandhills receive cm of rainfall per year, just like the more hydric ecosystems surrounding them. Sandhills are xeric because they have poor water holding capacity. Dominant vegetation includes longleaf pine (''Pinus palustris''), American turkey oak ('' Quercus laevis''), and wiregrass ('' Aristida stricta''). A number of rare animals are typical of this habitat including the gopher tortoise ('' Gopherus polyphemus''), red-cockaded woodpecker (''Picoides borealis''), Sherman's fox squirrel ('' Sciurus niger shermani''), and striped newt ('' Notophthalmus perstriatus'').

Longleaf Pine
The longleaf pine (''Pinus palustris'') is a pine species native to the Southeastern United States, found along the coastal plain from East Texas to southern Virginia, extending into northern and central Florida. In this area it is also known as "yellow pine" or "long leaf yellow pine", although it is properly just one out of a number of species termed yellow pine. It reaches a height of and a diameter of . In the past, before extensive logging, they reportedly grew to with a diameter of . The tree is a cultural symbol of the Southern United States, being the official state tree of Alabama. Contrary to popular belief, this particular species of pine is not officially the state tree of North Carolina. Description The bark is thick, reddish-brown, and scaly. The leaves are dark green and needle-like, and occur in bundles of mainly three, sometimes two or four, especially in seedlings. They often are twisted and in length. A local race of ''P. palustris'' in a cove near Rock ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Dunes Of The United States
A dune is a landform composed of wind- or water-driven sand. It typically takes the form of a mound, ridge, or hill. An area with dunes is called a dune system or a dune complex. A large dune complex is called a dune field, while broad, flat regions covered with wind-swept sand or dunes with little or no vegetation are called ''ergs'' or ''sand seas''. Dunes occur in different shapes and sizes, but most kinds of dunes are longer on the stoss (upflow) side, where the sand is pushed up the dune, and have a shorter ''slip face'' in the lee side. The valley or trough between dunes is called a ''dune slack''. Dunes are most common in desert environments, where the lack of moisture hinders the growth of vegetation that would otherwise interfere with the development of dunes. However, sand deposits are not restricted to deserts, and dunes are also found along sea shores, along streams in semiarid climates, in areas of glacial outwash, and in other areas where poorly cemented sa ...

Gopherus Polyphemus
The gopher tortoise (''Gopherus polyphemus'') is a species of tortoise in the family Testudinidae. The species is native to the southeastern United States. The gopher tortoise is seen as a keystone species because it digs burrows that provide shelter for at least 360 other animal species. ''G. polyphemus'' is threatened by predation and habitat destruction. The gopher tortoise is a representative of the genus ''Gopherus'', which contains the only tortoises native to North America. The gopher tortoise is the state reptile of Georgia and the state tortoise of Florida. Etymology The specific name, ''polyphemus'', refers to the cave-dwelling giant, Polyphemus, of Greek mythology. Gopher tortoises are so named because of some species' habit of digging large, deep burrows like the gopher. Description The gopher tortoise is a fairly large terrestrial reptile which possesses forefeet well adapted for burrowing, and elephantine hind feet. These features are common to most tortoises. ...

Plant Communities Of The Eastern United States
Plants are predominantly photosynthetic eukaryotes of the kingdom Plantae. Historically, the plant kingdom encompassed all living things that were not animals, and included algae and fungi; however, all current definitions of Plantae exclude the fungi and some algae, as well as the prokaryotes (the archaea and bacteria). By one definition, plants form the clade Viridiplantae (Latin name for "green plants") which is sister of the Glaucophyta, and consists of the green algae and Embryophyta (land plants). The latter includes the flowering plants, conifers and other gymnosperms, ferns and their allies, hornworts, liverworts, and mosses. Most plants are multicellular organisms. Green plants obtain most of their energy from sunlight via photosynthesis by primary chloroplasts that are derived from endosymbiosis with cyanobacteria. Their chloroplasts contain chlorophylls a and b, which gives them their green color. Some plants are parasitic or mycotrophic and have lost the abi ...
