Impacts on Coastal Ecosystems

Coastal ecosystems - mangroves, coral reefs, seacheps meadows, salt marshes, anddune systems - vary dramatically in their responses to cyclone comburance. The scale of damage depends on storm intensity, duration of exposure, the biological criteria of thee ecosystem, ande the historical comburance regime. Comburantly, many of these ecosystems have evolved with cyclone activity and rely on peridic commance to maintain diversity and function.
