The Baja California peninsula is a peninsula in northwestern Mexico. It separates the Gulf of California from the Pacific Ocean. The peninsula extends from Mexicali, Baja California, in the north to Cabo San Lucas, Baja California Sur, in the south.
Baja California Sur, officially Estado Libre y Soberano de Baja California Sur, is the least populated state and the 31st admitted state of the 32 federal entities which comprise the 31 States of Mexico. It is also the ninth-largest Mexican state in terms of area.
The Sonoran Desert is a hot desert in North America and ecoregion that covers the northwestern Mexican states of Sonora, Baja California, and Baja California Sur, as well as part of the southwestern United States. It is the hottest desert in both Mexico and the United States. It has an area of 260,000 square kilometers (100,000 sq mi).
The Baja California desert is a desert ecoregion of Mexico's Baja California peninsula. This ecoregion occupies the western portion of the Baja California peninsula, and occupies most of the Mexican states of Baja California Sur and Baja California. It covers 77,700 square kilometers. The climate is dry, but its proximity of the Pacific Ocean provides humidity and moderates the temperature. The flora mostly consists of xeric shrubs and over 500 species of recorded vascular plants.
Marismas Nacionales–San Blas mangroves is a mangrove ecoregion of the Pacific coast of Mexico. The marismas nacionales stretches from Mazatlán, Sinaloa southwards to San Blas, Nayarit.
Ojo de Liebre Lagoon, translated into English as "hare eye lagoon", is a coastal lagoon located in Mulegé Municipality near the town of Guerrero Negro in the northwestern Baja California Sur state of Mexico. It lies approximately halfway between the southern tip of the Baja California Peninsula and the U.S.-Mexico border, opening onto the Pacific Ocean.
The sea urchins of the Gulf of California live between the coasts of the Baja California Peninsula to the west and mainland state of Sonora, Mexico to the east. The northern boundary is the lateral band of land with the remains of the Colorado River Delta, and the southern is the Pacific Ocean.
The Esmeraldas-Pacific Colombia mangroves (NT1409) is an ecoregion of mangrove forests along the Pacific coast of Colombia and Ecuador. It is threatened by human population growth, leading to over-exploitation for wood and clearance for farming and aquaculture.
The Sinaloan dry forests is a tropical dry broadleaf forest ecoregion in western Mexico. It is the northernmost ecoregion of the Neotropical realm.
The Magdalena Transition is a marine ecoregion in the eastern Pacific Ocean. It includes the coastal waters along the southwestern Baja California Peninsula, extending from Punta Abreojos in the north to Cabo San Lucas at the peninsula's southern tip.
The Mesoamerican Gulf-Caribbean mangroves ecoregion covers the series of disconnected mangrove habitats along the eastern coast of Central America. These salt-water wetlands are found in river deltas, lagoons, and low-lying areas facing the Gulf of Mexico and Caribbean Sea, from Tampico, Mexico to central Panama. The mangroves are areas of high biodiversity and endemism. Many of the sites are protected as national parks or nature reserves.
The Belizean reef mangroves ecoregion covers the mangrove habitats along the islands and cayes of the Belize Barrier Reef. This ecoregion is distinct from the mainland Belizean Coast mangroves ecoregion, and may be considered a sub-unit of the overall Mesoamerican Gulf-Caribbean mangroves ecoregion.
The Mexican South Pacific Coast mangroves ecoregion covers the mangrove sites along the coast of the Pacific Ocean coast of Mexico, across the states of Michoacán, Guerrero, and Oaxaca. These mangrove forests are mostly around lagoons, typically those fed by rivers from the interior in the Sierra Madre del Sur Mountains. The ecoregion is small: collectively, it covers only 1,295 km2.
The Moist Pacific Coast mangroves ecoregion covers a series of disconnected mangrove sites along the Pacific Ocean coast of Costa Rica and Panama. These sites occur mostly on coastal flatlands around lagoons, particularly where rivers from the inland mountains reach the sea, bringing fresh water to the coastal forests. The area is in a transition zone from the drier coastline to the north; rainfall in this ecoregions is over 2,000 mm/year, and reaches over 3,600 mm/year at the southern end.
The Northern Dry Pacific Coast mangroves ecoregion covers the mangrove habitats in a series of sites along the Pacific Ocean coast of Guatemala and El Salvador. This part of Central America is relatively dry compared to higher elevations or more southerly areas, so the wetland mangroves serve as a refuge for animals of the interior during the winter dry season. The mangroves only extend a few kilometers inland to where the salt water influence is gone; the ecoregion surrounding the mangroves is the Central American dry forests ecoregion.
The Mayan Corridor mangroves ecoregion covers the mangrove habitats along the Caribbean Sea coast of the state of Quintana Roo in southern Mexico and a narrow strip on the north of Belize. The region is named for the Maya Civilization archeological sites along the coast. Biodiversity in the area high due to the interactions of different environments - coastal lagoons, river estuaries, coral reefs, and barrier beaches. The ecoregion supports Mexico's largest population of crocodiles.
The Petenes mangroves ecoregion covers mangrove habitat along the Gulf of Mexico coast of southern Mexico, where Campeche state and Yucatan state meet, centering on the Celestun Lagoon inland from the barrier-island town of Celestún. Because the region has relatively little rainfall and no rivers feeding the lagoons, the freshwater to support the mangrove ecosystem springs from underground aquifers. The area is important for migratory birds, and as a nesting area for sea turtles. The area around the Celestun Lagoon is protected by the Ría Celestún Biosphere Reserve, a UNESCO Biosphere Reserve, and Los Petenes Biosphere Reserve in Campeche.
The Tehuantepec-El Manchon mangroves ecoregion covers a series of mangrove woodlands along the Pacific Ocean coast of the state of Chiapas, Mexico. The ecoregion is relatively large and continuous, with trees up to 25 meters in height. The region supports stands of a type of yellow mangrove that normally only grown further south. The coast of Mexico here is wet - over 2,500 mm/year of rain. Four RAMSAR wetlands of international important are found in the zone, and a UNESCO Biosphere Reserve. Of particular importance are the wide variety of permanent and migratory birds in the area.
The Usumacinta mangroves ecoregion covers the mangrove forests ont the Gulf Coast of Mexico, around the margins of the Laguna de Términos. The "Ends" in the name refer to the mouths of the rivers that empty into the lagoon, including the Usumacinta River. This region, which is due south of the mouth of the Mississippi River across the Gulf of Mexico, receives an estimated one-third of the wintering birds migrating on the Mississippi Flyway. It is estimated that the lagoon supports 90 endangered species.
The biosphere reserves of Mexico are protected natural areas. Some are designated by the national government, while others are internationally designated by UNESCO.
