Biodiversité

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. Our fifth report in the State of the World’s series lays out the current condition of the world’s plants and fungi globally, and is titled 'Tackling the Nature Emergency: Evidence, gaps and priorities'

Growing evidence suggests that forest management practices are threatening the long-term conservation of a number of animal, fungi, and plant species worldwide. Although unmanaged forests are considered important for biodiversity, forest management continues to affect these vital habitats. We systematically reviewed the scientific literature to gain insight into the effects of forest management abandonment on biodiversity. We calculated log response ratio effect sizes to perform a meta-analysis on species richness between still managed (MAN) and no longer managed (NLM) forests, throughout the world's boreal and temperate forest ecosystems.
