Supports the forest hydrology and soil sustainability programme with responsibilities including GIS and data management.
Samantha Broadmeadow obtained a first degree in Biology at Durham University in 1989 followed by an MSc in Landscape Ecology Design and Management at Wye College, University of London in 1994. She joined Forest Research in 1995, and has specialised in forest hydrology since 1999.
Use of GIS to identify potential areas for woodland creation to alleviate flooding, reduce diffuse pollution, control soil erosion and improve freshwater ecology in various regions across the UK
Application of GIS in the assessment of site environmental predisposition factors to disease
Application of GIS to assess the extent of woodland cover in catchments at risk from acidification
Application of GIS to critically assess forest management in catchments known to support vulnerable species such as freshwater pearl mussel.

Rationale, approach and students of the Forest Hydrology Research Programme
Brief introduction to the targeting of Countryside Stewardship woodland capital grants in England
Opportunity mapping has been developed to help identify these locations and promote more integrated catchment management.
Results from an ongoing study in lowland streams in the New Forest
The impact of forestry on the ecological functioning of the freshwater environment
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 driven by objections to afforesting the sensitive peaty […]
Analysis of 22 years of water chemistry data from afforested Welsh catchments revealed trends indicative of recovery from acidification
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). This […]
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 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 available in an additional document. The results provide a strong basis for developing and refining catchment strategies, initiatives […]
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 […]

The principal roles of Forest Research in this Defra programme were to provide expert advice and to deliver a range of site specific environmental, soil and vegetation-related parameters and data-sets required for the evaluation of the Critical Loads calculation methodology. This evaluation includes the testing and calibration of process-based dynamic models of soil chemistry. By Mark […]
This guide describes the catchment approach that is being developed by a partnership of organisations in Cumbria in northwest England to control sediment inputs to Bassenthwaite Lake. It sets out the steps taken to identify the main sources of sediment and explores how woodland could help to alleviate the problem. By: By Tom Nisbet, Samantha Broadmeadow […]
