Tijuana River Estuary
The Tijuana Estuary (or Tijuana River Estuary) is an intertidal coastal wetland at the mouth of the Tijuana River in San Diego County, California, United States, bordering Tijuana, Baja California, Mexico. It is the location of Tijuana River National Estuarine Research Reserve, Tijuana Slough National Wildlife Refuge, Border Field State Park, and the Tijuana River Valley Regional Park. The estuary is a shallow water habitat. It was designated a National Natural Landmark in 1973. Ecology The estuary is one of the few remaining intact coastal wetlands on the South Coast (California), South Coast. Its location positions it under the path of the Pacific Flyway, where it serves as a stopover point. It is the largest remaining natural coastal area between Santa Barbara, California, and San Quintín, Baja California. The north arm is where the main body of the tidal salt marsh is located, while the south arm is on the opposite side. Three times the size of Central Park, the estuary cover ...

California
California () is a U.S. state, state in the Western United States that lies on the West Coast of the United States, Pacific Coast. It borders Oregon to the north, Nevada and Arizona to the east, and shares Mexico–United States border, an international border with the Mexico, Mexican state of Baja California to the south. With almost 40million residents across an area of , it is the List of states and territories of the United States by population, largest state by population and List of U.S. states and territories by area, third-largest by area. Prior to European colonization of the Americas, European colonization, California was one of the most culturally and linguistically diverse areas in pre-Columbian North America. European exploration in the 16th and 17th centuries led to the colonization by the Spanish Empire. The area became a part of Mexico in 1821, following Mexican War of Independence, its successful war for independence, but Mexican Cession, was ceded to the U ...

Central Park
Central Park is an urban park between the Upper West Side and Upper East Side neighborhoods of Manhattan in New York City, and the first landscaped park in the United States. It is the List of parks in New York City, sixth-largest park in the city, containing , and the most visited urban park in the United States, with an estimated 42 million visitors annually . It is also one of the most filmed locations in the world. The creation of a large park in Manhattan was first proposed in the 1840s, and a park approved in 1853. In 1858, landscape architects Frederick Law Olmsted and Calvert Vaux won a Architectural design competition, design competition for the park with their "Greensward Plan". Construction began in 1857; existing structures, including a majority-Black settlement named Seneca Village, were seized through eminent domain and razed. The park's first areas were opened to the public in late 1858. Additional land at the northern end of Central Park was purchased in ...

Lagoons Of San Diego County, California
A lagoon is a shallow body of water separated from a larger body of water by a narrow landform, such as reefs, barrier islands, barrier peninsulas, or isthmuses. Lagoons are commonly divided into ''coastal lagoons'' (or ''barrier lagoons'') and ''atoll lagoons''. They have also been identified as occurring on mixed-sand and gravel coastlines. There is an overlap between bodies of water classified as coastal lagoons and bodies of water classified as estuaries. Lagoons are common coastal features around many parts of the world. Definition and terminology Lagoons are shallow, often elongated bodies of water separated from a larger body of water by a shallow or exposed shoal, coral reef, or similar feature. Some authorities include fresh water bodies in the definition of "lagoon", while others explicitly restrict "lagoon" to bodies of water with some degree of salinity. The distinction between "lagoon" and "estuary" also varies between authorities. Richard A. Davis Jr. restricts "l ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wetlands Of California
A wetland is a distinct semi-aquatic ecosystem whose groundcovers are flooded or saturated in water, either permanently, for years or decades, or only seasonally. Flooding results in oxygen-poor (anoxic) processes taking place, especially in the soils. Wetlands form a transitional zone between waterbodies and dry lands, and are different from other terrestrial or aquatic ecosystems due to their vegetation's roots having adapted to oxygen-poor waterlogged soils. They are considered among the most biologically diverse of all ecosystems, serving as habitats to a wide range of aquatic and semi-aquatic plants and animals, with often improved water quality due to plant removal of excess nutrients such as nitrates and phosphorus. Wetlands exist on every continent, except Antarctica. The water in wetlands is either freshwater, brackish or saltwater. The main types of wetland are defined based on the dominant plants and the source of the water. For example, ''marshes'' are wetlands d ...

Estuaries Of California
An estuary is a partially enclosed coastal body of brackish water with one or more rivers or streams flowing into it, and with a free connection to the open sea. Estuaries form a transition zone between river environments and maritime environments and are an example of an ecotone. Estuaries are subject both to marine influences such as tides, waves, and the influx of saline water, and to fluvial influences such as flows of freshwater and sediment. The mixing of seawater and freshwater provides high levels of nutrients both in the water column and in sediment, making estuaries among the most productive natural habitats in the world. Most existing estuaries formed during the Holocene epoch with the flooding of river-eroded or glacially scoured valleys when the sea level began to rise about 10,000–12,000 years ago. Estuaries are typically classified according to their geomorphological features or to water-circulation patterns. They can have many different names, such as bays, ha ...

Mexico–United States Border Wall
The Mexico–United States border wall is a series of disjoined physical barriers built along portions of the Mexico–United States border.
