In my work with Wild Asia I recently helped produce a guide to migratory birds in oil palm plantations. The aim of this guide (three others will follow this one) is to inform plantation managers of the value of the wild spaces in their plantations for migratory birds, and what can be done to enhance these.
If you want to download a pdf version of the guide and posters, you can do so at this link. If you'd like hard copies, please contact Wild Asia (not me!).
