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, […]
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.
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 […]
Background Forests are recognised to reduce flood flows, although the issue is complex and continues to be explored. While the processes of how trees affect the generation and conveyance of flood waters are understood, there remains a lack of monitoring data to quantify effects at the catchment scale (click here to visit the WWNP evidence base webpage). […]
Floodplains are important natural capital assets which
deliver a wide range of benefits to people. The interface
between terrestrial and freshwater ecosystems in
floodplains fosters both a wealth and a complexity of
resources that are challenging to measure and compare.
The 'Runoff Curve Number' rainfall-runoff model, developed by the USDA Soil Conservation Service, was applied to the catchments draining to Omagh, to assess the potential effect of woodland creation on flood flows. The 'Runoff Curve Number' method provides a potentially powerful tool for evaluating the impact of land use change and management on surface runoff, […]
The report provide results, methods and details of the source data used in a mapping project to provide GIS spatial datasets which identify priority areas for woodland creation to benefit flood risk management in Northern Ireland. Maps are also avaliable in an addtional document. The results provide a strong basis for developing and refining catchment […]
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 […]
This report assesses the distribution of the Welsh peatlands, gives an overview of the likely impacts of peat forming factors and afforested peatland restoration, develops national and field based assessment schemes for the assessment of afforested peatland in Wales viable for restoration, carries out a national GIS assessment identifying potential restoration areas in Wales, tests […]
By Bill Rayner and Bruce Nicoll This assessment was instigated by Forestry Commission Scotland, with the aim of appraising the suitability of the hill watershed directly above the A83 at the ‘Rest and Be Thankful’ in Glen Croe for tree planting and the potential for the trees and shrubs to reduce the incidence of debris […]
