Tree improvement is a crucial strategy to enhance the quality and resilience of British timber. It is primarily achieved through traditional selective breeding whereby individuals are chosen based on desired physical traits, such as form and vigour or disease resistance, and brought together to produce seed and investigate genetics. For timber production, these superior trees are known as plus trees and are dominant, healthy individuals with straight and circular stems, good apical dominance and light branching (Figure 1). At Future Trees Trust we work with a range of native and naturalised broadleaved species commonly planted for commercial forestry: ash, birch, cherry, oak, sweet chestnut and sycamore. We partner with landowners across Britain and plant: i) orchards to produce seed, ii) field trials to assess parental performance through progeny testing, iii) provenance trials to investigate adaptation, and iv) clonal archives to conserve genetic resources.
