All ecosystems have the ability to withstand stress. They are able to resist being disturbed or altered and will restore themselves to their original condition if not disturbed too drastically. There are both natural and human induced stresses. An ecosystem is the dynamic complex interaction of plant‚ animal and microorganism communities and their non-living environment as a functional unit. Ecosystems include the biotic (living) and abiotic (non-living) elements of the environment and the relationships

In any case‚ we do not know enough about interspecies relationships and ecosystem balance and its stability to allow any gene pool to get eroded or obliterated. Large gene pools are also important to agriculturists. All domestic crops and livestock have originated from native plants and animals. All those native species are still

They normally grow above mean (average) sea level in intertidal zones of marine coastal environments as well as estuarine margins. A mangrove also refers to the tidal habitat comprising of such trees and shrubs. Australian mangrove systems are highly effecting by human presence

For a long time invertebrates have been used as indicators to assess water quality. Bottom-dwelling organisms
