Human activities often result in areas of bare land and open water that can become colonised by plants and animals.
This wasteland is unmanaged and organisms that live there are often those associated with early succession.
Wasteland sites can provide unusual habitats so can be home to many rare or exotic organisms - so often become protected areas.
Corridor habitats = strips of land such as embankments by railroad tracks and motorways to allow plants and animals to move between habitats
Sites previously developed for human use.
Offer a variety of habitats, some of which may be rare due to urbanisation or agriculture.
Intensive agriculture has led to the loss of flower-rich grasslands
Many flora (plants) and fauna (animals) have found homes in brown-field sites.
