State of the World's Plants and Fungi

We publish annual reports to give our assessment of the current knowledge on the world's plants and fungi.

Kew’s State of the World’s Plants and Fungi project provides assessments of our current knowledge of the diversity of plants and fungi on Earth, the global threats that they face, and the policies to safeguard them.

Launched in conjunction with a new website and an international scientific symposium, Kew’s State of the World’s Plants and Fungi sets an important international standard from which we can annually track trends in their global status.

State of the World's Fungi Symposium 2018

In conjunction with the publication of a cutting-edge annual report, scientists and policymakers gathered at Kew for the first international State of the World's Fungi Symposium on 13–14 September 2018. 

Building on the success of our State of the World’s Plants reports and website, the State of the World’s Fungi report provides a review of our current state of knowledge and the major issues affecting fungal diversity and abundance. Also featured are plant–fungal interactions, conservation and uses of fungi, and the fungal tree of life. 

This two-day symposium brought together fungal and plant scientists, ecologists, conservationists and industry and policy experts from around the world, to discuss issues raised in the report.

State of the World's Fungi Report 2018

The 2018 State of the World’s Fungi report aims to provide an overview of the current knowledge of the world's fungi. The report highlights the importance of fungi to all life on Earth, examining their diversity and distribution, their uses in everyday life, the global impact of positive plant–fungal interactions and the challenges associated with fungi including plant diseases and climate change.

Over 100 scientists from 18 countries have worked in collaboration with Kew Science to scrutinise databases, published literature, policy documents and reports to synthesise the latest discoveries and knowledge into this horizon-scanning report.
