An analysis of relevant species trials was carried out to assess the productivity of potential alternative conifer species to Sitka spruce on upland site types in Britain. Data from 87 forest experiments planted between 1929 and 1995 were analysed to compare long-term performance of 52 species with that of Sitka spruce under the same conditions and site type.
Understanding how we can increase the resilience of forest systems to future extreme drought events is increasingly important as these events become more frequent and intense. Diversifying production forests using intimate mixtures of trees with complementary functional traits is considered as one promising silvicultural approach that may increase drought resilience. However, the direction and magnitude […]
The changing climate is affecting our trees, forests and woodlands, how they grow and survive and the important ecosystem services they provide. For our forests and woodlands to thrive, adaptation measures must be considered carefully, and action taken. Ten measures to reduce climate risks and improve resilience are presented.
Milder and wetter winters, followed by increased spring rainfall, are likely to enhance the survival and infection potential of many tree pathogens. Hotter, drier summers leading to drought stress in trees will also increase their susceptibility to disease and expand the distribution range of some pathogens. The increased incidence and severity of diseases caused by Phytophthora species reduces the benefits that trees provide, including climate change mitigation.
Many studies quantify short-term drought impact on tree growth relative to pre-drought growth averages. However, fewer studies examine the extent to which droughts of differing severity differentially impact tree growth or shape stand dynamics. Focusing on three droughts in high and low density stands of Pinus sylvestris in Scotland, we calculated pre-drought growth averages using […]
Understanding the impacts of extreme drought on forest productivity requires a comprehensive assessment of tree and forest resilience. However, current approaches to quantifying resilience limit our understanding of forest response dynamics, recovery trajectories and drought legacies by constraining the temporal scale and resolution of assessment. We compared individual tree growth histories with growth forecasted using […]
Genome sequencing is used to determine the origins and genetic diversity of Dothistroma populations throughout the UK, and confirms the findings of our earlier paper discerning population structure with microsatellite analysis.

Protecting our forests from pollutant deposition is and has been a topical issue for some time. Nitrogen, as well as being an essential nutrient for trees, is one of the most important of these pollutants. This article discusses the extent and severity of the issues associated with nitrogen pollution in our forests. By Fiona Kennedy. […]
