Having considered some reasons why biodiversity might be important
we now provide some evidence as to why managed landscapes might be
so signii cant in supporting biodiversity conservation goals. Managed
landscapes that are vital economically in supporting human populations
can also make a very important contribution to biodiversity conservation.
Biodiversity can coexist alongside human activities and economically
