Belize's Wetlands: A Natural Paradise

Wetlands in Belize are primarily coastal wetlands, often extending from lagoons where freshwater meets saltwater from the sea. These wetlands are found in low-lying areas and are saturated with water for extended periods, acting as giant sponges that absorb and retain large amounts of water, which is crucial for preventing floods during heavy rainfall. Belize is home to the Sarstoon Temash National Park, a complex ecosystem recognised under the Ramsar Convention, featuring flooded forests, saline swamps, and the country's largest undisturbed stand of red mangroves. Wetlands in Belize also include areas like Ambergris Caye, where mangroves, seagrass, and lagoons provide essential habitats for marine life and birds, while also offering recreational opportunities for nature enthusiasts. While wetlands in Belize are facing threats, conservation efforts in protected areas have led to successful forest regrowth, showcasing the country's commitment to safeguarding these vital ecosystems.

Wetlands in Belize are disappearing

The loss of wetlands in Belize has significant implications for the environment and local communities. Wetlands are crucial for preventing flooding during heavy rainfall and the rainy season. They also help to trap sediments and toxins from terrestrial runoff, maintaining the health of the island's ecosystem and coral reef. Additionally, wetlands provide important habitat for many animal species, including fish, birds, and invertebrates, and offer recreational areas for activities such as fishing, kayaking, and birdwatching.

The mangroves in Belize's coastal wetlands play a crucial role in stabilizing shorelines and buffering coastal areas from the full impact of storms and flooding. They also contribute to mitigating climate change by removing carbon from the atmosphere and storing it in their soils. When mangrove ecosystems are removed for development, the soils are exposed to oxygen, causing rapid decomposition and the release of carbon dioxide into the atmosphere, exacerbating climate change.

To address the disappearance of wetlands, Belize has committed to protecting and restoring mangrove and seagrass ecosystems as part of its nationally determined contribution (NDC) to the Paris Agreement. This decision was informed by a research project led by the Smithsonian Institution in partnership with local organizations, which estimated the amount of carbon stored in the country's mangroves. Local communities in Belize also play an active role in reporting illicit activities and helping with restoration efforts.

Belize's wetlands are critical for climate change mitigation

Belize's wetlands are critical in the fight against climate change. These wetlands, often found in low-lying areas with shallow layers of water, act as giant sponges, absorbing and retaining large volumes of water, which is crucial for preventing floods during heavy rainfall. They also play a vital role in maintaining water quality by trapping sediments, toxins, and nutrients from terrestrial runoff, which benefits the surrounding ecosystems, including the coral reef.

Belize's coastal wetlands, such as those on Ambergris Caye, are formed when freshwater from the land mixes with saltwater from the sea, creating brackish water. This brackish water supports a diverse range of life, including phytoplankton, benthic microflora (algae), and macroflora (seagrass and mangroves). These ecosystems provide essential habitats for numerous species, including fish, crocodiles, and migratory and resident birds, some of which are threatened, such as the Roseate Spoonbill and Reddish Egret.

The Sarstoon Temash National Park, located in the Toledo district, is another vital wetland area in Belize. This complex ecosystem, recognised under the Ramsar Convention, encompasses a variety of terrestrial ecosystems, including flooded forests, sphagnum moss bogs, saline swamps, and mangrove stands. The park provides a haven for several vulnerable and threatened species, including the Black Howler Monkey, Hickatee Turtle, tapir, West Indian Manatee, and Morelett's Crocodile.

The importance of these wetland ecosystems extends beyond their ecological value. Wetlands are effective carbon sinks, trapping and storing carbon over centuries or even millennia. Belize has recognised the significance of this by including nature-based solutions in its commitments to the Paris Agreement. By safeguarding coastal wetlands and restoring mangrove and seagrass ecosystems, Belize aims to mitigate climate change, protect its coastlines, and preserve critical habitats for wildlife.

However, the wetlands of Belize face significant threats. Research by the University of Texas at Austin, using NASA satellite imagery, has revealed alarming losses of wetlands in the country, particularly outside protected areas. Between 2014 and 2016, the shift to industrial agriculture resulted in a 28.2% loss of wetlands in the Orange Walk District. Population growth and changing farming practices have contributed to the conversion of wetland areas for agricultural use.

Wetlands are found in Ambergris Caye

The wetlands of Ambergris Caye are coastal wetlands, often extending from lagoons where freshwater meets saltwater, creating brackish water with a diverse mix of phytoplankton, benthic microflora (algae), and macroflora (seagrass and mangroves). This productive ecosystem attracts a variety of animals, including crocodiles, fish, and migratory and resident birds, such as the threatened Roseate Spoonbills and Reddish Egrets.

The presence of seagrass and water hyacinths in these wetlands helps trap sediments and toxins from terrestrial runoff, benefiting the coral reef and the overall health of the island's ecosystem. Together with mangroves, they also contribute to stabilising the island structure, providing protection from strong winds and waves during storms.

Wetlands in Ambergris Caye offer aesthetic and recreational value, attracting nature enthusiasts, kayakers, and birdwatchers. They are recognised as vital for the island's resilience and the conservation of the diverse flora and fauna that depend on them. However, like other wetlands in Belize, they face threats from agricultural needs and development pressures, highlighting the importance of conservation efforts to protect these fragile ecosystems.

Overall, the wetlands of Ambergris Caye play a critical role in maintaining the ecological balance, providing habitat for numerous species, and offering recreational opportunities for visitors and locals alike. Their preservation is essential for the long-term health and resilience of Belize's natural environment.

Sarstoon Temash National Park is a wetland site

Wetlands are areas where the soil is saturated with water for extended periods and are usually located in low-lying areas with a shallow layer of water. They are often referred to as "giant sponges" due to their ability to absorb and retain large amounts of water, making them crucial in preventing flooding during heavy rainfall. Belize is known for its mangrove wetlands, which play a vital role in stabilising shorelines, mitigating climate change, and providing habitat for numerous species.

Sarstoon Temash National Park, designated in 1994, is a protected wetland site in southern Belize, covering 165.92 square kilometres. The park is jointly managed by the Sarstoon Temash Institute for Indigenous Management (SATIIM) and the Belize Forest Department. It is bounded by the Sarstoon River to the south, forming the border with Guatemala, and the Caribbean Sea to the east.

The park boasts a diverse range of habitat types, including seasonally and permanently flooded tropical forests. The wetland habitats within the park are particularly notable. They include 1,100 hectares of freshwater sphagnum moss bog, a unique feature in the region, and the only stands of comfra palm (Manicaria saccifera) in Belize. The park also features a transition zone from brackish to saline water, with an inland lagoon connecting the freshwater wetlands to 9,600 hectares of saline mangrove swamps. These mangrove swamps are the largest and least disturbed in Belize, providing critical habitat for numerous species.

The Sarstoon Temash National Park is recognised for its ecological significance, having been designated a wetland of international importance under the Ramsar Convention in 2005. This recognition underscores the importance of safeguarding this precious wetland ecosystem and the vital role it plays in conservation, climate mitigation, and providing a habitat for numerous species, including some that are threatened or vulnerable.

Wetlands in Belize are crucial for wildlife

Belize's wetlands include coastal areas, such as those found on Ambergris Caye, as well as freshwater and brackish marshes, swamps, and lagoons that occur throughout the country. These wetlands play a vital role in maintaining the country's biodiversity and providing habitat for numerous species.

One of the key ways in which wetlands are crucial for wildlife is by providing a spawning and nursery ground for many species of fish. The lagoons and mangroves of Ambergris Caye, for example, are used as spawning and nursery grounds by fish such as mutton snapper, cubera, and tarpon. These habitats also attract migratory and resident birds, such as Roseate Spoonbills and Reddish Egrets, which depend on the wetlands for food.

In addition to their importance for fish and birds, wetlands in Belize are also crucial for invertebrates and mammals. For example, the mangroves and seagrass ecosystems provide important habitat and food sources for conch, a type of invertebrate that is an important food source for local communities. Belize's wetlands also provide habitat for endangered black howler monkeys, as well as Morelet's crocodiles, armadillos, and anteaters.

Furthermore, wetlands play a crucial role in maintaining water quality and promoting healthy coral reef systems. The presence of seagrass and water hyacinths in wetland habitats helps trap sediments and toxins from terrestrial runoff, which would otherwise degrade the island's ecosystem and coral reefs. By filtering nutrients and sediments out of tidal waters, wetlands help to increase water clarity and promote the growth of healthy coral reefs.

Belize has recognized the importance of its wetland ecosystems and has committed to protecting and restoring them. In September 2022, the country included nature-based solutions, such as safeguarding coastal wetlands, in its updated nationally determined contribution (NDC) to the Paris Agreement on climate change. This decision underscores the crucial role that wetlands play in both wildlife conservation and climate change mitigation in Belize.
