Conservation of birds in fragmented landscapes requires protected areas by Robert Timmers.

*Already in 1996 Prof. Dr Pieter A. Zuidema and Prof. Dr Jeffrey A. Sayer (Chairholder 1994-2003) had foreseen this. They wrote the paper Forest fragmentation and biodiversity: the case for intermediate-sized conservation areas.

The report ‘Forests for the Future – Restoration Success at Landscape Scale: What will it Take and What Have we Learned?’ is a contribution to the Bonn Challenge - a global target to bring 350 million hectares of degraded and deforested land into restoration by 2030. Since the Challenge was set in 2011, 74 governments, private associations and companies have pledged more than 210 million hectares.

The report showcases insights from researchers and practitioners at the coalface of forest and ecosystem restoration around the world on the greatest opportunities, as well as the most fundamental challenges, that need to be addressed in the coming years.

The report is the culmination of work under the most recent Prince Bernhard Chair, Utrecht University, Professor Jaboury Ghazoul (2015-2020).
