 Revegetation is often used to join up patches of natural habitat that have been lost and can be a very important tool in places where much of the natural vegetation has been cleared.It is therefore particularly important in urban environments, and research in Brisbane has shown that revegetation projects can significantly improve urban bird populations The Brisbane study showed that connecting a revegetation patch with existing habitat improved bird species richness, while simply concentrating on making large patches of habitat was the best way to increase bird abundance.Revegetation plans, therefore, need to consider how the revegetated sites are connected with existing habitat patches.
