The Belize Barrier Reef is a series of coral reefs straddling the coast of Belize, roughly 300 meters (980 ft) offshore in the north and 40 kilometers (25 mi) in the south within the country limits. The Belize Barrier Reef is a 300 kilometers (190 mi) long section of the 900 kilometers (560 mi) long Mesoamerican Barrier Reef System, which is continuous from Cancún on the northeast tip of the Yucatán Peninsula through the Riviera Maya up to Honduras making it one of the largest coral reef systems in the world after the Great Barrier Reef in Australia and the New Caledonia Barrier Reef. It is Belize's top tourist destination, popular for scuba diving and snorkeling and attracting almost half of its 260,000 visitors, and is vital to its fishing industry.[1]

Charles Darwin described it as "the most remarkable reef in the West Indies" in 1842.

Species[edit]

The Belize Barrier Reef is home to a large diversity of plants and animals, and is one of the most diverse ecosystems of the world:

With 90% of the reef still needing to be researched, it is estimated that only 10% of all species have been discovered.[2]

Environmental protection[edit]

Belize also became the first country in the world to completely ban bottom trawling in December of 2010.[3][4] A large portion of the reef is protected by the Belize Barrier Reef Reserve System, which includes seven marine reserves, 450 cays, and three atolls. It totals 960 square kilometres (370 sq mi) in area, including:

In 1996 the Reserve System was designated a World Heritage Site due to its vulnerability and the fact that it contains the most important and significant natural habitats for in-situ conservation of biological diversity (according to criteria VII, IX, and X).

Despite these protective measures, the reef is under threat from oceanic pollution as well as uncontrolled tourism, shipping, and fishing. The main threats are considered to be hurricanes along with global warming and the resulting increase in ocean temperatures,[5] which cause coral bleaching. It is claimed by scientists that over 40% of Belize's coral reef has been damaged since 1998.[1]

The Belize Barrier Reef has been affected by two mass-bleaching events. The first mass bleaching occurred in 1995, with an estimated mortality of 10 percent of coral colonies, according to a report by the Coastal Zone Management Institute in Belize. A second mass-bleaching event occurred, when Hurricane Mitch struck in 1998. Biologists observed a 48 percent reduction in live coral cover across the Belize reef system.

Usually, it is hard to distinguish whether the reason for coral bleaching is human activities or natural reasons such as storms or bacterial fluctuations. But in the case of the Belize Barrier Reef, many factors which make the distinction difficult do not apply. Human population in this area is much more sparse than the corresponding areas near other coral reefs, so the human activity and pollution are much lower compared to other coral reefs and the Belize reef system is in a much more enclosed area.

When coral bleaching occurs, a large part of the coral dies, and the remaining part of the ecosystem begins the process of repairing the damage. But the chances of recovery is low, as corals that are bleached become much more vulnerable to disease. Disease often kills more corals than the bleaching event itself. With continuous bleaching, the coral reef will have little to no chance of recovery.[6]
