Flora and vegetation of Belize
Encyclopedia
The flora of Belize is highly diverse by regional standards, given the country's small geographical extent. Situated on the Caribbean coast of northern Central America the flora and vegetation have been intimately intertwined with Belize's history. The nation itself grew out of British timber extraction activities from the 17th century onwards, at first for logwood

Vegetation types

The vegetation of Belize was first systematically surveyed in the 1930s. Recent mapping projects have employed the following principal terrestrial and coastal categories of native vegetation:
  • lowland broad-leaved forest. This is a diverse forest type in Belize, now greatly reduced in extent by clearance for agricultural land. It includes such tropical tree species as Simarouba glauca
    Simarouba glauca
    Simarouba glauca is a species of flowering tree that is native to Florida in the United States, southern Mexico, Central America, and the Greater Antilles. Common names include Paradise Tree, Aceituno, and Bitterwood. Its seeds produce an edible oil. The tree is well suited for warm, humid,...

  • lowland savanna. This is an important vegetation type in northern Belize, in which scattered trees occur in "short grass" (actually mainly sedges).

In addition to the above there are numerous other important forest reserves such as:

There are numerous conservation challenges in Belize. One is the extensive recent illegal cutting of the understorey palms, xate (Chamaedorea spp). This has a severe effect on the health and reproduction of these characteristic understorey components.

 study conducted by the Water Center for the Humid Tropics of Latin America and the Caribbean (CATHALAC) and NASA, in collaboration with the Forest Department and the Land Information Centre (LIC) of the Government of Belize's Ministry of Natural Resources and the Environment (MNRE), and published in August 2010 revealed that Belize's forest cover in early 2010 was approximately 62.7%, down from 75.9% in late 1980. A similar study by Belize Tropical Forest Studies and Conservation International revealed similar trends in terms of Belize's forest cover. Both studies indicate that each year, 0.6% of Belize's forest cover is lost, translating to the clearing of an average of 24,835 acres (9,982 hectares) each year. The USAID-supported SERVIR study by CATHALAC, NASA, and the MNRE also showed that Belize's protected areas have been extremely effective in protecting the country's forests. While only some 6.4% of forests inside of legally declared protected areas were cleared between 1980 and 2010, over a quarter of forests outside of protected areas had been lost between 1980 and 2010. As a country with a relatively high forest cover and a low deforestation rate, Belize has significant potential for participation in initiatives such as REDD

Because of their importance for shoreline protection and maintenance of fisheries stocks, Belize's mangroves are legally protected under the Forests Act of the Laws of Belize. A recent study by the World Resources Institute (WRI) indicates, in fact, that Belize's mangrove ecosystems contribute US $174–249 million per year to the national economy. Clearing of mangroves for development of coastal infrastructure has nonetheless been recognized as a threat to Belize's mangroves and led to public perception that destruction of mangrove ecosystems was rampant, such as an investigative study in 2008 which indicated unauthorized clearings within the South Water Caye Marine Reserve, and which eventually led to the Belize Barrier Reef System's designation by UNESCO

 to comprehensively examine Belize's mangrove cover. That study, which spanned the thirty years from 1980–2010 and was based on the earlier work of mangrove researcher Simon Zisman, was conducted by the Water Center for the Humid Tropics of Latin America and the Caribbean (CATHALAC) and found that in 2010, mangroves covered some 184,548 acres (74,684 hectares) or 3.4% of Belize's territory. By contrast, it is estimated that in 1980 mangrove cover stood at 188,417 acres (76,250 hectares) - also 3.4% of Belize's territory. Based on Zisman, it is also estimated that Belize's mangrove cover in 1980 represented 98.7% of the pre-colonial extent of those ecosystems. Belize's mangrove cover in 2010 was thus estimated to represent 96.7% of the pre-colonial cover. Where the 2010 update of the World Mangrove Atlas also indicated that a fifth of the world's mangrove ecosystems have been lost since 1980, the case of Belize's mangroves thus stands in stark contrast to the global picture. Belize's relative mangrove cover in fact declined by a mere 2% from 1980–2010, and in that period, under 4,000 acres of mangroves had been cleared, although clearing of mangroves near Belize's main coastal settlements (e.g. Belize City
