Sandhill High School
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''). Invasive species that are a problem on sandhills include Cog ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Aristida Stricta
''Aristida stricta'' is a warm-season grass, native to North America, that dominates understory vegetation in sandhills and flatwoods coastal plain ecosystems of the Carolinas in the Southeastern United States. It is known as wiregrass (due to its texture) and pineland three-awn grass. Its common name, wiregrass, gave rise to the naming of the Wiregrass Region The Wiregrass region or Wiregrass country is an area of the Southern United States encompassing parts of southern Georgia, southeastern Alabama, and the Florida Panhandle. The region is named for the native ''Aristida stricta'', commonly known ... in which it is located. This is a fast-growing species that regenerates quickly after fires. The plant depends on regular summer burning in order to stimulate flowering and seed production.

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 ability ...

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 ...

Wildfire Ecology
A wildfire, forest fire, bushfire, wildland fire or rural fire is an unplanned, uncontrolled and unpredictable fire in an area of combustible vegetation. Depending on the type of vegetation present, a wildfire may be more specifically identified as a bushfire( in Australia), desert fire, grass fire, hill fire, peat fire, prairie fire, vegetation fire, or veld fire. Some natural forest ecosystems depend on wildfire. Wildfires are distinct from beneficial human usage of wildland fire, called controlled burning, although controlled burns can turn into wildfires. Fossil charcoal indicates that wildfires began soon after the appearance of terrestrial plants approximately 419 million years ago during the Silurian period. Earth's carbon-rich vegetation, seasonally dry climates, atmospheric oxygen, and widespread lightning and volcanic ignitions create favorable conditions for fires. The occurrence of wildfires throughout the history of terrestrial life invites conjecture that fi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Natal Grass
''Melinis repens'' is a species of grass known by the common names rose Natal grass, Natal red top, or simply Natal grass.

Invasive Species
An invasive species otherwise known as an alien is an introduced organism that becomes overpopulated and harms its new environment. Although most introduced species are neutral or beneficial with respect to other species, invasive species adversely affect habitats and bioregions, causing ecological, environmental, and/or economic damage. The term can also be used for native species that become harmful to their native environment after human alterations to its food webfor example the purple sea urchin (''Strongylocentrotus purpuratus'') which has decimated kelp forests along the northern California coast due to overharvesting of its natural predator, the California sea otter (''Enhydra lutris''). Since the 20th century, invasive species have become a serious economic, social, and environmental threat. Invasion of long-established ecosystems by organisms is a natural phenomenon, but human-facilitated introductions have greatly increased the rate, scale, and geographic range of ...

Notophthalmus Perstriatus
The striped newt (''Notophthalmus perstriatus'') is a species of aquatic salamander native to the southeastern United States. It is a close relative of the eastern newt, with which it shares territory, and can be distinguished from the latter by the presence of red stripes running down the sides of its back and red spots on its back that lack a black outline.http://museum.nhm.uga.edu/gawildlife/amphibians/caudata/salamandridae/nperstriatus.html Description Growing from in length, a fully mature striped newt is yellow-green to olive green to black-brown in color with bright red or orange parallel dorsal stripes. The underside is yellow with black spots. The aquatic larvae are tan, greenish, or brown with bushy external gills and have a distinct light lateral line and dark mottling on the large tail fin. The striped newt can also occur as an eft, which is a terrestrial juvenile stage that spends several years completely on land. Efts can be identified by their light brown or oran ...

Red-cockaded Woodpecker
The red-cockaded woodpecker (''Leuconotopicus borealis'') is a woodpecker endemic to the southeastern United States. Description The red-cockaded woodpecker is small to mid-sized species, being intermediate in size between North America's two most widespread woodpeckers (the downy and hairy woodpeckers). This species measures in length, spans across the wings and weighs . Among the standard measurements, the wing chord is , the tail is , the bill is and the tarsus is . Its back is barred with black and white horizontal stripes. The red-cockaded woodpecker's most distinguishing feature is a black cap and nape that encircle large white cheek patches. Rarely visible, except perhaps during the breeding season and periods of territorial defense, the male has a small red streak on each side of its black cap called a ''cockade'', hence its name. The species is listed as Near Threatened by the IUCN and as Endangered by the United States Fish and Wildlife Service. Behavior The red ...
