Big Sandy Creek (Village Creek)
Big Sandy Creek is a stream in Texas, United States. It rises in Polk County before flowing approximately southeast into Hardin County where it merges with Kimball Creek, forming Village Creek. Long sections of the creek pass through the Big Thicket National Preserve. The Big Sandy Creek unit is named after the stream. The creek also passes through the Alabama-Coushatta Reservation reservation east of Livingston. Ecology and wildlife Bottomland hardwood forests and beech-magnolia-loblolly slope forests can be found in the stream's floodplain, while pine savannas occupy the adjacent uplands. Common tree species seen in the bottomlands include sweetgum (''Liquidambar styraciflua''), swamp chestnut oak (''Quercus michauxii''), hornbeam (''Carpinus caroliniana''), Hollies ('' Ilex sp.''), and bald cypress (''Taxodium distichum''). Outside of the national preserve, the Alabama-Coushatta people manage and protect longleaf pine ecosystems on their land. Prescribed fire and ref ...

Carpinus Caroliniana
''Carpinus caroliniana'', the American hornbeam, is a small hardwood tree in the genus ''Carpinus''. American hornbeam is also known as blue-beech, ironwood, musclewood and muscle beech. It is native to eastern North America, from Minnesota and southern Ontario east to Maine, and south to eastern Texas and northern Florida. It also grows in Canada (southwest Quebec and southeast Ontario). It occurs naturally in shaded areas with moist soil, particularly near the banks of streams or rivers, and is often a natural constituent understory species of the riverine and maritime forests of eastern temperate North America. Description American hornbeam is a small tree reaching heights of , rarely , and often has a fluted and crooked trunk. The bark is smooth and greenish-grey, becoming shallowly fissured in all old trees. The leaves are alternate, long, with prominent veins giving a distinctive corrugated texture, and a serrated margin. The male and female catkins appear in spring at t ...

Geography Of Texas
The geography of Texas is diverse and large. Occupying about 7% of the total water and land area of the U.S., it is the second largest state after Alaska, and is the southernmost part of the Great Plains, which end in the south against the folded Sierra Madre Oriental of Mexico. Texas is in the South Central United States of America, and is considered to form part of the U.S. South and also part of the U.S. Southwest. By residents, the state is generally divided into North Texas, East Texas, Central Texas, South Texas, West Texas and, sometimes, the Panhandle, but according to the ''Texas Almanac'', Texas has four major physical regions: Gulf Coastal Plains, Interior Lowlands, Great Plains, and Basin and Range Province. This has been cited as the difference between human geography and physical geography, although the fact that Texas was granted the prerogative to divide into as many as five U.S. states may be a historical motive for Texans defining their state as containing ex ...

Big Thicket
The Big Thicket is the name given to a somewhat imprecise region of a heavily-forested area of Southeast Texas in the United States. This area represents a portion of the mixed pine-hardwood forests of southeast US. The National Park Service established the Big Thicket National Preserve (BTNP) within the region in 1974 and it is recognized as a biosphere reserve by UNESCO. Although the diversity of animals in the area is high, with over 500 vertebrates, it is the complex mosaic of ecosystems and plant diversity that is particularly remarkable. Biologists have identified at least eight, and up to eleven, ecosystems in the Big Thicket area. More than 160 species of trees and shrubs, 800 herbs and vines, and 340 types of grasses are known to occur in the Big Thicket, and estimates as high as over 1000 flowering plant species and 200 trees and shrubs have been made, plus ferns, carnivorous plants, and more. The Big Thicket has historically been the most dense forest region in what is n ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Slope Forest, Big Thicket NP, Big Sandy Creek, Polk Co
In mathematics, the slope or gradient of a line is a number that describes both the ''direction'' and the ''steepness'' of the line. Slope is often denoted by the letter ''m''; there is no clear answer to the question why the letter ''m'' is used for slope, but its earliest use in English appears in O'Brien (1844) who wrote the equation of a straight line as and it can also be found in Todhunter (1888) who wrote it as "''y'' = ''mx'' + ''c''". Slope is calculated by finding the ratio of the "vertical change" to the "horizontal change" between (any) two distinct points on a line. Sometimes the ratio is expressed as a quotient ("rise over run"), giving the same number for every two distinct points on the same line. A line that is decreasing has a negative "rise". The line may be practical – as set by a road surveyor, or in a diagram that models a road or a roof either as a description or as a plan. The ''steepness'', incline, or grade of a line is measured by the absolute ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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.

Longleaf Pine Ecosystem
The longleaf pine ecosystem is a climax savanna habitat found within the Southern United States; it includes many rare plant and animal species, and is one of the most biodiverse in North America. Once the largest ecosystem in North America, it now occupies less than a quarter of the original range. Degradation of the ecosystem is partially due to excessive timber harvesting, urbanization, and fire exclusion. Although the ecosystem is heavily fragmented at present, it still carries a great diversity of plant and animal species, many of which are endemic. A range of techniques, including planting longleaf pine seedlings, introducing prescribed burning regimens, managing native ground cover, and controlling invasive species within the ecosystem, are used in attempting to preserve this threatened ecosystem. Original range During the Ice Age, when the North American continental glaciers extended as far south as parts of the Ohio River, the climate was colder and drier; longleaf pine ...

Quercus Michauxii
''Quercus michauxii'', the swamp chestnut oak, is a species of oak in the white oak section ''Quercus'' section ''Quercus'' in the beech family. It is native to bottomlands and wetlands in the southeastern and midwestern United States, in coastal states from New Jersey to Texas, inland primarily in the Mississippi–Ohio Valley as far as Oklahoma, Missouri, Illinois, and Indiana. Description The leaves of the swamp chestnut oak are simple (not compound), long and broad, with 15–20 lobe-like, rounded simple teeth on each side, similar to those of chestnut oak and chinkapin oak (''Quercus muehlenbergii''), although they generally do not achieve the more slender form that the leaves of those trees may exhibit at times. The leaves turn red in autumn. The fruit is an acorn long and broad, borne on a 2–3 cm peduncle, maturing in the fall, about 6 months after pollination. The tree only bears heavy acorn crops at intervals of several years. Taxonomy The swamp ches ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
