This booklet is an attempt to redress the lack of general knowledge on target_idal flats and create awareness about their importance and the current threats facing these little-known ecosystems.
Coastal lagoons and estuaries, lying at the boundary between ocean and land, house a unique mosaic of habitats, giving rise to high species diversity and the creation of ecotones. They are also ecologically and economically important ecosystems that provide many ecosystem services. Yet, these coastal ecosystems are facing a gamut of human-induced threats.
Seagrass meadows and sand dunes are lesser known coastal ecosystems that are located landward from coral reefs and sometimes seaward from mangroves. (At other times mangroves lie between seagrasses and sand dunes.) These ecosystems are also important for coastal communities because of the services they provide and are critical components of a vital, interdependent and interconnected series of coastal ecosystems.
Corals are a vital component of marine ecosystems. They provide food and protection for a huge variety of fish and marine life; are crucial to sustaining livelihoods among coastal populations; and a key mechanism for ensuring the protection of low-lying coastal areas. Despite their importance, the worlds coral reefs are being destroyed and disappearing at an alarming rate.
Mangroves are among the most important ecosystems on the planet. They provide food and protection for a huge variety of marine and land-based species, sustain livelihoods of coastal populations, and provide protection from ocean swell and extreme weather events. Today, however, the worlds mangroves are under threat from several sources including coastal development and the impacts of climate change.
