In the UK, National Tree Week (26 November – 4 December) celebrates tree planting within local communities. The latest BES cross-journal Virtual Issue contains recent papers that highlight the global importance of trees and forests as habitat – for species from insects to primates – and in meeting human needs for fuel and agriculture. The selected papers also demonstrate novel methods scientists are using to study trees and forests.
National Tree Week is the UK’s largest tree celebration. It was started in 1975 by the Tree Council and has grown into an event that brings hundreds of organisations together to mark the beginning of Britain’s winter tree planting season.
Landscape connectivity is important for the ecology and genetics of populations threatened by climate change and habitat fragmentation. To begin our Virtual Issue Rayfield et al. present a method for identifying a multipurpose network of forest patches that promotes both short- and long-range connectivity. Their approach can be tailored to local, regional and continental conservation initiatives to protect essential species movements that will allow biodiversity to persist in a changing climate. The authors illustrate their method in the agroecosystem bordered by the Laurentian and Appalachian mountain ranges, that surrounds Montreal.
