Question: what's the difference between wetland and coral reef

title: Wetland
text: Prescribed Natural Regeneration There are no biophysical manipulation and the ecosystem is left to recover based on the process of succession alone . The focus of this method is to eliminate and prevent further disturbance from occurring . In order for this type of restoration to be effective and successful there must be prior research done to understand the probability that the wetland will recover with this method . Otherwise , some biophysical manipulation may be required to enhance the rate of succession to an acceptable level determined by the project managers and ecologists . This is likely to be the first method of approach for the lowest level of disturbance being that it is the least intrusive and least costly . Assisted Natural Regeneration There are some biophysical manipulations however they are non-intrusive . Example methods that are not limited to wetlands include prescribed burns to small areas , promotion of site specific soil microbiota and plant growth using nucleation planting whereby plants radiate from an initial planting site , and promotion of niche diversity or increasing the range of niches to promote use by a variety of different species . These methods can make it easier for the natural species to flourish by removing competition from their environment and can speed up the process of succession . Partial Reconstruction Here there is a mix between natural regeneration and manipulated environmental control . These manipulations may require some engineering and more invasive biophysical manipulation including ripping of subsoil , agrichemical applications such as herbicides and insecticides , laying of mulch , mechanical seed dispersal , and tree planting on a large scale . In these circumstances the wetland is impaired and without human assistance it would not recover within an acceptable period of time determine by ecologists . Again these methods of restoration will have to be considered on a site by site basis as each site will require a different approach based on levels of disturbance and ecosystem dynamics . Complete Reconstruction The most expensive and intrusive method of reconstruction requiring engineering and ground up reconstruction . Because there is a redesign of the entire ecosystem it is important that the natural trajectory of the ecosystem be considered and that the plant species will eventually return the ecosystem towards its natural trajectory .
