Diversity in forests is essential to conserve biodiversity and expand habitats, and to contribute towards enhancing landscape quality and recreation opportunities. In addition, introducing species and age diversity throughout a forest can increase their resilience to pests, diseases and fire, and extend economic opportunities.
This Practice Guide offers advice and ideas from which a forest manager […]
