Article Synopsis
- Insect and disease outbreaks in forests are increasingly problematic due to climate change, which disrupts ecosystem services like carbon storage and biodiversity conservation.
- The Database of European Forest Insect and Disease Disturbances (DEFID2) compiles over 650,000 records of such disturbances from 1963 to 2021 across eight European countries, utilizing methods like ground surveys and remote sensing.
- DEFID2 provides detailed qualitative and quantitative data on forest disturbances, enabling researchers to study ecological processes and assess the impacts of these biotic disturbances more effectively.
Non-native pests, climate change, and their interactions are likely to alter relationships between trees and tree-associated organisms with consequences for forest health. To understand and predict such changes, factors structuring tree-associated communities need to be determined. Here, we analysed the data consisting of records of insects and fungi collected from dormant twigs from 155 tree species at 51 botanical gardens or arboreta in 32 countries.

Seedling protection by chemicals is gradually being restricted or banned for environmental reasons, and non-chemical alternatives are therefore needed. In this 3-year study, we compared the following five treatments for protecting Norway spruce seedlings against H.
