A study of chemical runoff following the use of acetamiprid as a pre-treatment and top-up spray to prevent damage from the large pine weevil (Hylobius abietis L.) to young trees was undertaken at a restock site in mid-Wales. The site was specifically selected to pose a high risk of chemical runoff, being a high elevation, […]
Research and Guidance
The large pine weevil (Hylobius abietis) is the most serious pest of newly planted or naturally regenerating woodland trees on restocking sites in the UK and Ireland. On affected sites, in the absence of protective measures, losses of replanted trees will average around 50%, but in the worst...
This project investigates the potential to use green infrastructure (including woodland planting) to deliver a sustainable approach to managing flood risk. The strategic road network in England faces a significant increase to disruption and risk of injury due to flooding. Predicted changes in rainfall linked to climate change will require improved...
This research aims to find out how to expand woodland cover in a way that maximises ecological and social benefits. The programme complements the other six programmes and follows collaborative principles to produce tools which support land managers, stakeholders and policy makers to increase engagement with woodland creation activities
Report assessing the long term role of forestry in relation to the acidification and recovery of soil and surface water. It targets some of the most acid impacted head waters in the Galloway region of southwest Scotland, including three sub-catchments in the Black Water of Dee (Dargall Lane, Green Burn and Cuttie Shallow); Cardoon Burn […]
Highlights Good forest practice was effective at protecting water quality. Streamwater acidity and ecology unaffected by conifer afforestation. Hurricanes caused marked changes in streamwater acidity and water colour. Total P increased after fertiliser applications but no impact on ecological status. Findings will inform future woodland expansion within sensitive water catchments. Abstract Our study was […]

Many parts of the UK are periodically affected by flooding and the frequency of floods is expected to increase due to climate change. Tree planting and forest management can alter flood flows, although the extent of this depends on many factors. Here we describe the latest understanding of how forestry can help.
It is difficult to generalise about the effects of forestry on water resources, however some important distinctions can be drawn between the impact of conifers and broadleaves in the uplands and lowlands.
Forests have long been associated with an ability to reduce flood flows, however valuing the contribution that forest cover makes to downstream flood alleviation is very difficult given the multiple factors and associated uncertainties involved.
Despite a strong understanding of the processes by which woods and trees affect the generation and...
Timber structures placed in watercourses and on their floodplains are effective NFM measures, restricting the flow and potentially holding large volumes of water during flood events, helping to reduce downstream flood risk. In an environment where constant wetting and drying occurs, timbers used for NFM measures have a high susceptibility...
Summary of a workshop for researchers, policy makers and practitioners to discuss the progress and practicalities of developing a National Ecological Network in Scotland. Embedded in this approach to more sustainable land use is the need to take stock of progress towards regional and national ecological networks to increase resilience into the future.
The Forest Design Plan for Whinlatter is currently under review and a new aspirations map has been produced. This includes measures such as habitat creation and proposed extensions to the mountain bike trail network. In addition to these proposals, measures to reduce the community flood risk have been considered; such as soft engineering features (leaky […]
Forest Research was commissioned by Forestry England to carry out a desk-based GIS exercise to determine the potential opportunities of implementing NFM measures in 4 forest areas in the Derwent Catchment. The study focused on the Parkwood Isel, Howgill and Messengemire, Setmurthy and Matterdale forest areas. A desk-based GIS exercise was carried out by Forest […]
