ALERT member James Watson tells us about important new research on the world's last surviving primary forests.
Primary forests -- those largely free from industrial-scale land uses, and where natural processes still dominate -- provide maximum ecosystem benefits to humans and nature.
Primary forests are essential for biodiversity conservation, and in the face of a rapidly changing climate they will provide critical refugia for many vulnerable species and sustain the maximum natural adaptive capacity.
However, new research by my colleagues and I -- which you can download free here -- has shown how threatened the world's primary forests are. Just one-quarter of all primary forests still survive on Earth, with a mere 5 percent of these found in protected areas.
Despite increasing global awareness, annual rates of primary-forest loss remain as high as 2 percent in some countries.
Importantly, our study found that half of the world's primary forests occur in five developed nations -- the USA, Canada, Russia, Australia, and New Zealand -- and the time is ripe for these nations to show leadership and promote the conservation of remaining primary forests as an urgent matter of global concern.
This is critically important in international negotiations -- such as the Convention on Biological Diversity, and United Nations Framework Convention on Climate Change -- as all fail to distinguish primary forests from industrial production forests, degraded forests, or even plantations.
Now is the time to underscore the vital importance of vanishing primary forests and their crucial benefits for nature and human welfare.
