Mangrove Park: Belize's Natural Paradise

Mangrove Park is located in Belize, Central America, along the country's 386km coastline and cayes. Mangroves cover 3.4% of Belize's land surface, and can be found in a belt along the coastal zone, as well as near freshwater rivers, where they thrive on nutrients from upstream. Belize is home to three types of mangrove: red, black and white, as well as a subspecies called buttonwood. Mangroves are a vital part of the Belizean ecosystem, providing a protective barrier between the sea and inland areas, and acting as feeding and nursery grounds for a variety of species.

Mangrove ecoregions in Belize

Mangroves are a vital ecosystem in Belize, with around 3.5% of the country's land area covered by these unique trees. Belize is home to three types of mangrove: red, black, and white, as well as a subspecies known as buttonwood. These trees are known for their ability to grow in seawater, with their roots forming in the muddy shallows from seed pods called propagules.

Belize has two distinct mangrove ecoregions: the Belizean Coast mangroves and the Belizean Reef mangroves. The Belizean Coast mangroves ecoregion covers the brackish and saltwater habitats along the Caribbean Sea coast of Belize, extending from the border with Mexico in the north to Amatique Bay on the southern coast of Guatemala. This ecoregion includes various types of mangrove swamps, such as river estuaries, lagoons, island atolls, and coastal forests. The Belizean Reef mangroves ecoregion, on the other hand, covers the mangrove habitats along the islands and cayes of the Belize Barrier Reef, stretching from the Mexico border to the south. It also extends across three coral atolls: Turneffe Atoll, Lighthouse Reef, and Glover's Reef.

The climate in both ecoregions is classified as a Tropical savanna climate with a dry winter. This climate is characterised by relatively consistent temperatures year-round and a distinct dry season, with the driest month receiving less than 60 mm of precipitation.

The Belizean Coast mangroves ecoregion is home to a diverse range of wildlife, including mammals such as the black howler monkey, the critically endangered Hickatee turtle, the tapir, and the vulnerable West Indian manatee. The Belizean Reef mangroves ecoregion also boasts an impressive array of wildlife, including the vulnerable West Indian manatee, the endangered green sea turtle, and the critically endangered hawksbill sea turtle.

Mangroves play a crucial role in the ecosystem by providing nursery and feeding grounds for many species, protecting coastlines from erosion and storm surges, and helping to mitigate climate change by storing large amounts of carbon in their soil. Unfortunately, mangroves in Belize are facing a significant threat from clearance due to increasing demand for coastal development.

Mangrove rehabilitation and restoration

Mangrove forests are a vital part of Belize's biodiversity, and their rehabilitation and restoration are crucial to the country's ecological health. These forests provide a safe breeding and nesting environment for birds such as anhingas, neotropical cormorants, brown boobies, and white ibis, as well as habitat for about 74 species of fish, 178 bird species, 11 amphibian species, 30 reptile species, and 40 mammal species. They also play a crucial role in stabilising the soil and dissipating wave energy, acting as a natural buffer between the sea and the mainland.

Despite legislation protecting the mangroves of Belize, their overall cover is decreasing due to expanding developments, including hotels and resorts, and the rising number of tourists. As a result, large areas of mangrove wetlands have been cleared to provide land for these developments.

The rehabilitation and restoration of mangroves in Belize require accurate attention to local hydrology and the basic biology of mangrove trees and their associated fauna. Long-term success will depend on various factors, including community involvement, appropriate governance structures, and alignment of objectives with local stakeholders.

One example of a rehabilitation project in Belize is the Mangrove Challenge, which was established in 2010-2011. This contest identified individuals involved in effective mangrove conservation and restoration across Belize and fostered the creation of networks among them. The challenge included awarding small cash prizes to conservation organisations, building projects that maintained mangroves, and educational opportunities created by boardwalks through mangrove forests.

Additionally, the Belize Association of Private Protected Areas (BAPPA) and the Belizean Mangrove Conservation Network encourage landowners to work towards the conservation and restoration of mangroves and other natural areas. Another local NGO, Friends of Placencia Lagoon, has documented the impacts of nearby shrimp farm effluent disposal on water quality.

The success of mangrove rehabilitation and restoration projects in Belize will depend on addressing the underlying causes of mangrove degradation and involving local communities in conservation efforts.

Types of mangrove in Belize

Mangroves are a crucial ecosystem in Belize, covering around 3.5% of the country's land area and bordering much of its 386-kilometre coastline. Belize is home to three primary types of mangrove: red, black, and white, with an additional subspecies known as buttonwood.

The red mangrove (Rhizophora mangle) is the most common species in the Caribbean and is easily identified by its long prop roots that provide support. These mangroves typically grow closest to the water, including along the edges of cayes and waterways. Red mangroves play a crucial role in the ecosystem by providing space for a large community of invertebrates, such as algae, sponges, and sea anemones, which in turn serve as food for lobsters, shrimps, and boxfish.

The black mangrove (Avicennia germinans) is usually found farther away from the water's edge. It can be recognised by the small protrusions called pneumatophores that encircle the base of the tree. These structures help facilitate gas exchange, similar to the long prop roots of the red mangroves. Black mangroves are also known for their ability to push salt out through special pores on their leaves.

The white mangrove (Laguncularia racemosa or Laguncalaria racemosa) and buttonwood (Conocarpus erectus) species are generally located even further away from the water's edge, growing inland or in upland areas. The buttonwood tree, also known as the false mangrove or mangrove associate, is considered a subspecies or associate of the primary mangrove types.

All four types of mangroves have adapted to tolerate a wide range of water conditions, from freshwater rivers to purely saline environments. They possess the ability to filter out salt before taking up water into their tissues or extrude it through their leaves. This adaptability allows them to flourish in environments that many other plant species cannot tolerate.

Unfortunately, despite legislation protecting the mangroves of Belize, their overall cover is decreasing due to expanding developments, including hotels and resorts, and the rising demand for coastal settlements. Conservation efforts are crucial to protect these vital ecosystems and the rich biodiversity they support.

The importance of mangroves

Mangroves are trees and shrubs with intricate root systems that form a type of tropical forest near bodies of water. Covering around 3.4% to 3.5% of Belize's land area, they are a vital ecosystem for the country. 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 an associate mangrove species known as the buttonwood (Conocarpus erectus).

Mangrove forests also provide essential protection for coastal regions. Acting as a buffer between marine and terrestrial communities, mangroves shield coastlines from severe weather events, strong winds, and floods, while also helping to prevent erosion by stabilising sediments. This protective function benefits nearby communities that are vulnerable to storms and the impacts of rising sea levels. Additionally, mangroves are a valuable resource for humans, providing construction materials, firewood, and fuel. They also offer economic opportunities, particularly for local fishermen who depend on the abundant fish populations that thrive in mangrove ecosystems.

Despite legislation protecting the mangroves of Belize, their overall cover is decreasing due to expanding developments, including hotels and resorts. The rise in deforestation and the threat of sea-level rise have put the mangroves, the biodiversity they support, and local communities at risk. It is crucial to raise awareness about the importance of mangroves and to take collective action to protect and conserve these vital ecosystems.

Mangrove tourism in Belize

The mangroves in Belize cover approximately 3.4% to 3.5% of the country's land area, mostly along its 386-kilometre coastline and cayes. They are a critical ecosystem, providing nursery and feeding grounds for numerous species, including fish, birds, amphibians, reptiles, and mammals. The intricate root systems of mangroves offer shelter and protection for marine life, while their dense foliage creates ideal nesting sites for birds. Additionally, mangroves play a vital role in stabilising soil, dissipating wave energy, and filtering and cleaning the water that flows towards the delicate coral reefs.

Belize's mangroves are not just environmentally significant but also culturally and economically important. Traditional fishing communities in Belize have long relied on mangroves for building traps, marking nets, and providing construction materials and fuel. With the country's economic shift towards tourism, the impact on the mangrove ecosystem has been mixed. On the one hand, tourism brings much-needed revenue, which can help fund conservation efforts and raise awareness about the importance of mangroves. On the other hand, the rapid development fuelled by tourism has led to the clearing of mangrove wetland areas to make way for resorts and infrastructure.

Despite legislation protecting the mangroves, their overall cover in Belize is decreasing. This loss is attributed to expanding developments and the challenges in enforcing environmental protection rules. However, there are efforts to strike a balance between tourism and mangrove conservation. For example, the idea of educational tours centred around mangroves has been suggested, aiming to raise awareness about the importance of these ecosystems and generate funds for replanting initiatives.

The Garifuna people in Hopkins, Belize, provide a notable example of community-led conservation efforts. Determined to preserve their traditional lands, they employ sustainable management practices to protect the old-growth mangrove forests their community depends on. Their resilience in the face of illegal deforestation and development pressures offers hope for the future of Belize's mangroves.
