Mangrove Diversity In Belize: Unveiling The Four Unique Species

Mangroves are a group of trees that can survive in salty soil and water, as well as low-oxygen and flooding conditions. Belize is home to four types of mangroves: red, black, white, and buttonwood. These trees cover around 3.4% to 3.5% of Belize's land, often found along the country's 386-kilometre coastline and cayes. They are a vital part of the ecosystem, acting as feeding and nursery grounds for numerous species of fish, birds, amphibians, reptiles, and mammals. With their ability to adapt to various water conditions, mangroves play a crucial role in filtering and purifying water, protecting the delicate coral reefs nearby. Despite legislation protecting them, the overall mangrove cover in Belize is decreasing due to expanding developments and tourism.

Red mangrove

The red mangrove, or Rhizophora mangle, is the most common species of mangrove in the Caribbean and is generally found closest to the water in Belize. It is easily identified by its long prop roots, which support the plant and help it to gain access to oxygen even when the roots are partially submerged. These prop roots also facilitate gas exchange.

The growth in size of red mangroves depends largely on the nutritional content of the site, rather than the salt content or the age of the plant. In some mangrove forests, trees as high as a house grow next to dwarf plants of the same age.

Black mangrove

The black mangrove, scientifically known as *Avicennia germinans*, is one of the four types of mangroves found in Belize. It is characterised by small protrusions called pneumatophores that encircle the base of the tree on the ground. These pneumatophores facilitate gas exchange, allowing the tree to breathe even when its roots are partially submerged underwater. Black mangroves are usually found farther away from the water's edge, unlike the red mangrove, which is typically closest to the water.

These mangroves provide crucial ecological functions, serving as feeding and nursery grounds for numerous species. They are home to approximately 74 species of fish and 178 bird species, as well as providing habitats for 11 species of amphibians, 30 species of reptiles, and 40 species of mammals. The black mangrove's root system, similar to stilts, provides support and stability to the tree, especially in muddy areas.

Despite legislation protecting the mangroves of Belize, their overall coverage is decreasing due to expanding developments, including hotels and resorts, and the rise of mass tourism. This loss of mangrove cover is not unique to Belize, as similar declines are observed worldwide. The conservation of black mangroves and other mangrove species is essential, as they play a vital role in protecting the mainland from storms and flooding, stabilising soil, and providing habitats for a diverse range of wildlife.

White mangrove

Belize is home to three types of mangrove: the red mangrove, the black mangrove, and the white mangrove. Here is some more information about the white mangrove:

The white mangrove, or *Laguncularia racemosa*, is found farther inland or upland in Belize. It is one of the common mangrove tree species of the Belizean Coast mangroves ecoregion, which covers brackish and salt-water habitats along the Caribbean Sea coast of Belize and Amatique Bay in Guatemala. Mangroves are a group of trees that have adapted to survive in very salty soil and water conditions, as well as conditions of low oxygen and flooding. They are designed to use energy from non-living organic material, or detritus, in the sea, mudflats, or rivers. Their roots have organs that allow them to take in oxygen, even when partially submerged under water.

Unfortunately, despite legislation protecting the mangroves of Belize, their overall cover is decreasing due to expanding developments, including hotels and resorts, and the rise of mass tourism.

Buttonwood

Despite legislation protecting the mangroves of Belize, their overall cover is decreasing due to expanding developments, including hotels and resorts. Wetlands are being cleared to accommodate rising tourism in the region.

Mangrove distribution in Belize

Mangroves are a group of trees that can survive in very salty soil and water conditions, as well as low-oxygen environments and flooding. Belize is home to three types of mangrove: the red mangrove (*Rhizophora mangle*), the black mangrove (*Avicennia germinans*), and the white mangrove (*Laguncularia racemosa*). There is also a subspecies known as buttonwood (*Conocarpus erectus*). Mangroves cover 3.4%-3.5% of Belize's land, occurring in a belt along the country's 386km coastline and its cayes. They can also be found along the Western Highway, 12 miles from the coast, and near freshwater rivers, where they thrive on nutrients from upstream that collect among their dense roots.

The Belizean Coast mangroves ecoregion covers the brackish and saltwater habitats along the Caribbean Sea coast of Belize, and of Amatique Bay in Guatemala. It also includes small parts of Mexico that border Belize. The ecoregion is distinct from the Belizean Reef mangroves ecoregion, which is offshore. The disconnected units of the Belizean Coast mangroves ecoregion extend from the Mexico-Belize border in the north to Amatique Bay on the southern coast of Guatemala. The types of mangrove swamps vary depending on the site characteristics: river estuary (e.g. Monkey River), lagoons, island atolls, and coastal forest. Belize City itself is technically within a mangrove area. Offshore islands supporting mangroves include Ambergris Caye, the largest island of Belize, and the atoll reefs of Banco Chinchorro and Turneffe Atoll.

The red mangrove is the most common species in the Caribbean and is most often found along the water on cayes and waterways. It is easily identified by the long prop roots that support the plant. The black mangrove is usually found farther away from the water's edge and can be recognised by the small protrusions called pnuematophores that encircle the base of the tree on the ground. These pnuematophores help to facilitate gas exchange, as do the long prop roots found on the red mangroves. The white mangrove and buttonwood species are generally located even further away from the edge of the water.
