During quarrying operation, overburden materials are removed and dumped on site. Heaps of these materials are left uncovered. The uncovered materials, suitable for land reclamation, tends to get dry, erode, loss most of its nutrients, making it insufficient for biodiversity promotion. In most cases, habitats of organisms are destroyed.
The above undesirable effects can be reduced if a soil covering mechanism is adopted. One solution, is the use of cover crops. Cover crops are widely known for their ability to adapt to conditions, retain soil moisture and promote biodiversity.
At quarry sites and in communities are pieces of bare land and heaps of uncovered overburden materials, left to erode and loss their ability to sustain biodiversity. The research team seeks to investigate the moisture retention and biodiversity sustaining ability of Mimosa pudica, after which, the concept will be applied to sustain biodiversity at the quarry site and in communities. At the quarry site, the concept will be used to sustain biodiversity in the overburden materials. For the communities, the concept will be applied to retain moisture and keep pollinators on the farmlands. It is expected that, the floral part of Mimosa pudica will attract and keep on site the pollinators which will ensure ecological succession through the pollination.
This project will involve planting of Mimosa pudica on a bare land, monitoring soil moisture with time and recording the progress of biodiversity promotion.
