The influence of climate change on forest insect pests in Britain

Predicting future risks of damage by insect pests is an important aspect of forest management. Climate change has the potential to affect forest pests and their impact on trees through higher temperatures, altered precipitation patterns, and more frequent extreme weather events. Warmer temperatures are likely to have complex effects on insects, influencing, among other things, […]

Ecosystem services and forest management

The ecosystem services concept helps describe the benefits which humans receive from nature and natural processes in a way that can influence policy and management decision-making. The ability of trees, woodlands and forests to provide a wide range of ecosystem services is very much dependent on where they are located and how they are managed. […]

Forests as places of mental well-being for people with dementia

This Research Note is based on a PhD research study ‘Forests as places of mental well-being: the meaning and use of urban forests by people with early-stage dementia’. The study examines and develops ways for people with dementia (especially those in the early stages) to engage with nature, and with other people, in the context […]

Behavioural policy ‘nudges’ to encourage woodland creation for climate change mitigation

Evidence indicates that woodland creation is generally a cost-effective method of climate change mitigation, when compared with a range of alternatives. However, engaging landowners and land managers in woodland creation schemes can sometimes prove difficult, and this affects prospects for meeting national woodland planting targets and associated climate change mitigation objectives. Although reluctance to plant […]

Horse chestnut bleeding canker

Horse chestnut is an important amenity tree species which has been significantly affected over the past decade by a widespread outbreak of bleeding canker disease. Symptoms include rust-coloured or blackened bleeding cankers on the stem and branches, which can lead to tree mortality. The causal agent of this disease is the pathogenic bacterium Pseudomonas syringae […]

Forestry and surface water acidification

Forests and forest management practices can affect surface water acidification in a number of ways. The primary mechanism is the ability of tree canopies to capture more sulphur and nitrogen pollutants from the atmosphere than other types of vegetation. Pollutant scavenging is expected to have peaked in the 1970s when emissions were greatest and led […]

A framework for sharing experiences of community woodland groups

Community woodland groups are growing, and there are now over 650 groups in England, Scotland and Wales. The rise is the result of both social pressure and changes in policy. Groups are keen to learn from each other’s experiences, and policy stakeholders seek evidence of the effectiveness of past and current policy. While some experiences […]

Modelling ecological networks and dispersal in grey squirrels

Understanding the role of the landscape matrix in species dispersal is important when targeting conservation and management strategies. This Research Note shows how least-cost modelling was used to assess invasive grey squirrel Sciurus carolinensis dispersal movements within the UK, with a focus on the county of Cumbria. Two major networks were identified separated by the […]

Species preference of small mammals for direct-sown tree and shrub seeds

Direct seeding can be a useful method for creating new woodland on former agricultural sites. However, the success of the technique is variable when it is used to restore conifer plantation sites to native species. Seed predation by small mammals, particularly the wood mouse, has been identified as a factor potentially limiting success. Small mammals […]

Air temperature regulation by urban trees and green infrastructure

A well-known effect of urbanisation is the warming of the local climate relative to surrounding rural areas, creating a phenomenon known as the ‘urban heat island’ (UHI). UHI intensity varies across a city and over time, but temperature differences may reach 9 °C in the UK. Factors that contribute to a UHI include the thermal properties, […]

Natural regeneration in western hemlock plantations on ancient woodland sites

During the 20th century large areas of ancient semi-natural woodland were converted to conifer plantations, creating sites now termed PAWS (Plantations on Ancient Woodland Sites). Restoration of these sites to native woodland is a current objective of forestry policy throughout Great Britain. Natural regeneration is often regarded as the preferred method for restocking PAWS but […]

Biodiversity in fragmented landscapes

Maintaining species’ movement around landscapes is considered important if we are to conserve populations of many species and help them adapt to climate change. Particular features in the landscape have the potential to hinder or facilitate species movement. As each species interacts with the landscape differently, it can be hard to extract general patterns to […]
