Mangroves are some of the only coastal plants that can live in saltwater, and when conditions are favorable, they cover the coastline in dense patches known as mangrove forests or swamps. As the primary species involved in forming mangrove forests prefer very warm, wet conditions, they are restricted to tropical and warm temperate latitudes around the world. Indonesia, Thailand, and Mexico are some places with particularly large areas of mangrove forest. Like reef-building corals, mangroves are ecosystem engineers — they form their own ecosystem and provide habitat for several other species. Importantly, networks of these sediment-trapping forests buffer the coastline against wave-induced erosion and provide coastal ecosystems and coastal communities a vital line of defense against strong, tropical storms.
Mangrove forests also provide important nursery habitat for many species of fishes and invertebrates, including those that are commercially important fisheries species, which later move to coral reefs and other ecosystems as they mature. Without the protection that mangrove forests provide the juveniles of these species, their adult populations and the fishers who rely on their capture suffer. Furthermore, mangrove forests are a primary habitat for mature individuals of many species of seabirds and waterfowl and some terrestrial animals as well. The dual services of coastal protection and habitat for commercially important species make mangrove forests one of the most valuable ecosystems in the world.
Unfortunately, like many coastal and marine ecosystems, they are being lost at an extremely rapid rate. Clear cutting for coastal development projects including construction of shrimp farms, hotels, and other structures , harvesting for wood, and pollution all threaten mangrove forests throughout their range. Scientists estimate that at least one third of all mangrove forests have been lost during the last few decades. Without active policies that aim to reverse the negative trend and preserve this system, mangrove forests and the valuable services that they provide may disappear in some areas. Over 11 years, that has resulted in sightings of more than 13, individual organisms ranging from small scavenging invertebrates such as whelks, starfish and hermit crabs to large, highly mobile predatory vertebrates such as sharks and rays.
Bede Davies, who is currently completing his Ph. He said: "This research is the culmination of years of hard work and collaboration between researchers from the University and the fishers of Lyme Bay. It shows how the compromise between conservation and fisheries management can affect whole ecosystems, local habitats and those who rely on them. It also highlights the need for long term monitoring of MPAs and that, when managed appropriately, they can provide significant benefits to fisheries and conservation. The Lyme Bay MPA was the UK's first and largest example of an ambitious, whole-site approach to marine protection, which was designed to manage, recover and protect reef biodiversity by considering the whole ecosystem.
It has excluded bottom-towed fishing across km 2 of waters off the southern coast of England, protecting a mosaic of habitats from regular damage, while still allowing less destructive fishing methods, such as static gear, rod and line, and diving. The University's work in Lyme Bay, which has been funded at various stages by Defra, Natural England, the European Maritime and Fisheries Fund and the Blue Marine Foundation, has been carried out in conjunction with local fishers and other community groups along the Dorset and Devon coastline. She added: "Globally, the implementation of MPAs has increased rapidly over the last 25 years. They are a key element of international plans to protect and preserve the ocean however, as things stand, only 7. Our ongoing work in Lyme Bay has shown the positive effects of addressing that, and in the face of the global climate and biodiversity crises the need to do so has never been more pressing.
