Biodiversity, nature crisis, and natural forests

One of the significant challenges in Norway and worldwide is the loss of nature and biodiversity. Norway has signed the Kunming–Montreal Agreement (2024). This agreement requires us to protect at least 30% of all land area.

About the topic

In Norway, there are many protected alpine areas, but little forest protection, and almost no virgin forests remain. The state has recently mapped relatively large areas of potential natural forests that have not been exploited for the past two generations (>60 years). These forests have old trees and a natural regeneration with few introduced species. Measures for the conservation of forests and their species require good knowledge of the ecology and biogeography of the species. Data on distribution and environmental and climate requirements are essential for conserving endangered species. Understanding the biogeography of species is also crucial in managing introduced species, as some can pose a serious threat to native species diversity. The group focuses specifically on urban natural forests and how studies on the spread of introduced species impact them.
