Cooperation and Conflict in Conservation

By Michael Bode

Different groups are all “fighting” for the environment, but each group does it in its own way and with its own specific priorities – sometimes leading to negative conservation outcomes.

Systematic conservation planning is the absolute best-practice approach to conserving biodiversity in a large landscape. We create maps that highlight the distribution of our favourite conservation features – be they threatened species, vulnerable habitats, ecosystem services, or all of the above – and then we use these data to decide which locations are the most valuable. The result is a priority map: a chart of where our limited resources will do the most good for conservation.
