List of invasive species in the Everglades Invasive species in the Everglades are exotic plants and animals that are not native to the area and have aggressively adapted to conditions in wilderness areas in southern Florida. The Everglades are a massive watershed in the southern portion of the U.S. state of Florida that drains overflow from the vast shallow Lake Okeechobee that is in turn fed by the Kissimmee River. The overflow forms a very shallow river about 60 mi wide and 100 mi long that travels about half a mile per day. The network of ecosystems created by the Everglades are surrounded by urban areas to the east in the South Florida metropolitan area, to the west by Naples and Fort Myers, and to the south by Florida Bay, a marine environment that receives fresh water from and is maintained by the Everglades. As it is surrounded on three sides and close to a major transportation and shipping center, it is particularly vulnerable to the importation of exotic species.

Surficial aquifer Surficial aquifers are shallow aquifers typically less than 50 ft thick, but larger surficial aquifers of about 60 ft have been mapped. They mostly consist of unconsolidated sand enclosed by layers of limestone, sandstone or clay and the water is commonly extracted for urban use. The aquifers are replenished by streams and from precipitation and can vary in volume considerably as the water table fluctuates. Being shallow,they are liable to contamination by fuel spills, industrial discharge, landfills, and saltwater. Parts of southeastern United States are dependent on surficial aquifers for their water supplies.

Southeast Alaska Southeast Alaska, sometimes referred to as the Alaska Panhandle, is the southeastern portion of the U.S. state of Alaska, which lies west from the northern half of the Canadian province, British Columbia. The majority of Southeast Alaska's area is part of the Tongass National Forest, the United States' largest national forest. In many places, the international border runs along the crest of the Boundary Ranges of the Coast Mountains (see Alaska boundary dispute). The region is noted for its scenery and mild rainy climate.

Tidelands Tidelands are the territory between the high and low water tide line of sea coasts, and lands lying under the sea beyond the low-water limit of the tide, considered within the territorial waters of a nation. The United States Constitution does not specify whether ownership of these lands rests with the federal government or with individual states. Originally little commercial value was attached to tidelands, so ownership was never firmly established, but the coastal states generally proceeded as if they were the owners. Some states, such as Mississippi, directly administer these lands under the public trust doctrine.

Paleontology in Idaho Paleontology in Idaho refers to paleontological research occurring within or conducted by people from the U.S. state of Idaho. The fossil record of Idaho spans much of the geologic column from the Precambrian onward. During the Precambrian, bacteria formed stromatolites while worms left behind trace fossils. The state was mostly covered by a shallow sea during the majority of the Paleozoic era. This sea became home to creatures like brachiopods, corals and trilobites. Idaho continued to be a largely marine environment through the Triassic and Jurassic periods of the Mesozoic era, when brachiopods, bryozoans, corals, ichthyosaurs and sharks inhabited the local waters. The eastern part of the state was dry land during the ensuing Cretaceous period when dinosaurs roamed the area and trees grew which would later form petrified wood.

Oregon Coast The Oregon Coast is a region of the U.S. state of Oregon. It runs generally north–south along the Pacific Ocean, forming the western border of the state; the region is bounded to the east by the Oregon Coast Range. The Oregon Coast stretches approximately 363 mi from the Columbia River in the north to the California state border in the south. The Oregon Coast is not a specific geological, environmental, or political entity, but instead includes the entire coastline of Oregon, including the Columbia River Estuary.

Appalachian Ohio Appalachian Ohio is a bioregion and political unit in the southeastern part of the U.S. state of Ohio, characterized by the western foothills of the Appalachian Mountains and Appalachian Plateau. The Appalachian Regional Commission defines the region as consisting of thirty-two counties. This region roughly overlaps with the Appalachian mixed-mesophytic forests, which begin in southeast Ohio and southwest Pennsylvania and continue to north Georgia and Alabama. The mixed-mesophytic forest is found only in Central and Southern Appalachia and eastern/central China. It is one of the most biodiverse temperate forests in the world.

Lower Coastal Plain (Georgia) Southeast Georgia's Lower Coastal Plain is a subregion that encompasses the lowest-lying areas of the Atlantic coastal plain in the state, containing barrier islands, marshes, and swampy lowlands, as well as flat plains and low terraces. It differs from Georgia's Upper Coastal Plain in that it is lower in elevation with less relief and wetter soils. The United States Environmental Protection Agency defines the Lower Coastal Plain as an ecoregion, part of the larger, interstate Southern Coastal Plain.

Geography of South Dakota South Dakota is a state located in the north-central United States. It is usually considered to be in the Midwestern region of the country. The state can generally be divided into three geographic regions: eastern South Dakota, western South Dakota, and the Black Hills. Eastern South Dakota is lower in elevation and higher in precipitation than the western part of the state, and the Black Hills are a low, isolated mountain group in the southwestern corner of the state. Smaller sub-regions in the state include the Coteau des Prairies, Coteau du Missouri, James River Valley, the Dissected Till Plains, and the Badlands. Geologic formations in South Dakota range in age from two billion-year-old Precambrian granite in the Black Hills to glacial till deposited over the last few million years. South Dakota is the 17th-largest state in the country.

Florida Florida (Spanish for "land of flowers") is a state in the southeastern region of the United States. It is bordered to the west by the Gulf of Mexico and Alabama, to the north by Alabama and Georgia, to the east by the Atlantic Ocean, and to the south by the Straits of Florida. Florida is the 22nd-most extensive, the 3rd-most populous, and the 8th-most densely populated of the U.S. states. Jacksonville is the most populous municipality in the state, and is legally the largest city by area in the contiguous United States (due to the consolidation of Jacksonville with Duval County). The Miami metropolitan area is Florida's most populous urban area. The city of Tallahassee is the state capital.

Natchez District The Natchez District was one of two areas established in the Kingdom of Great Britain's West Florida colony during the 1770sthe other being the Tombigbee District. The first Anglo settlers in the district came primarily from other parts of British America. The district was recognized to be the area east of the Mississippi River from Bayou Sara in the south (presently St. Francisville, Louisiana) and Bayou Pierre in the north (presently Port Gibson, Mississippi). Today, this area corresponds roughly with and includes most of the lands south of Interstate 20 and west of Interstate 55 in the state of Mississippi, in the southwest corner of the state.

Northern Panhandle of West Virginia The Northern Panhandle is the northern of the two panhandles in the U.S. state of West Virginia. It is a culturally and geographically distinct region of the state. It is the state's northernmost extension, bounded by Ohio and the Ohio River on the north and west and the state of Pennsylvania on the east. Its unusual configuration is the result of the Revolutionary-era claims of Virginia's former Yohogania County boundary lying along the Ohio River, conflicting with interpretations of the Colony of Pennsylvania's royal charter. The conflict was settled by compromise in the 1780s. Today, due to the southern boundary being an extension of the Mason–Dixon line and the panhandle's proximity to the Pittsburgh area, the Northern Panhandle resembles more of the Midwestern United States or the Northeastern United States compared to the rest of the state (including the Eastern Panhandle of West Virginia), which is classified as part of the Upland South.
