<Dd> 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 . </Dd> <Li> Partial Reconstruction <Dl> <Dd> 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 determined 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 . </Dd> </Dl> </Li> <Dl> <Dd> Here there is a mix between natural regeneration and manipulated environmental control .
