“conserve the composition, structure, function and
evolutionary potential of biodiversity”
Dudley et al. 2008

For protected areas to conserve biodiversity, they must..
1) Be located in the right places
2) Be effectively managed for biodiversity

“17% of terrestrial areas are conserved through
effectively managed and ecologically
representative PAs by 2020”
“ensure ecological integrity and the protection of
species, habitats and ecosystem processes”

We know PAs can work
BUT
By focusing on area we
aren’t telling the full story

What is needed?
• Reporting on actual
coverage of biodiversity and
measures of human
pressure in protected areas
• Identify and address
shortfalls in PA estates– this
needs to be biodiversity
based and needs based
