When it comes to conservation, fungi are often overlooked. This module provides an introduction to fungi, explains their importance, and takes a look at their conservation. Fungi are a highly diverse group of organisms, though still not well understood. The various types of fungi have value for many reasons including as goods, for services and for essential ecological interactions. Like other organisms, fungi face common threats, e.g., climate change and habitat fragmentation, but face different conservation challenges due to scientific, informational and public concern hurdles.
