Mike co-leads the £2.2M ‘Sustainable Forest Management in Light of Environmental Change’ (SFM) Programme for the Forest Research Science & Innovation Strategy. He also leads the climate impacts group at Northern Research Station, focussed on forestry for climate mitigation, including measurement and analysis of stand-scale carbon and GHG balance and drought response of forests. The group undertakes underpinning research on forest management impacts, including at the Conifer Forest Carbon & GHG research platform.
Mike leads the Forest Research contribution to major NERC funded research programmes PRAFOR [landscape scale drought impact estimates, led by CEH] and FORESIGHT [Beech response to drought in UK and Europe, led by Stirling University].
Mike joined Forest Research in 2001. He has worked for over 25 years on tree response to climate and environment. Previously Mike studied for a PhD in ‘Conifer Water Relations in Response to Drought’ at the University of Edinburgh (1994-1998), and postdoctoral research utilising ecophysiological approaches (particularly chlorophyll fluorescence) at University College Dublin (1998-2001). Mike has a Applied Ecology BSc from John Moores University (1992), and an MSc (by Research) from University of Edinburgh (1994)
Mike is an Honorary Fellow, School of GeoSciences, Edinburgh University.
PhD supervision: Bertin, Beauchamp, Swain, Mackintosh, Leslie, Nair, Lonsdale, Davies, Mazzola (completed); Creber, Ovenden, Fletcher, Shield (in progress).

This research examines the potential of agroforestry to contribute to meeting greenhouse gas emissions reductions targets outlined in Scotland’s Climate Change Plan, and the economic viability of adopting agroforestry practices. It finds agroforestry has potential to sequester carbon and is generally financially viable, but benefits vary according to different factors.
Probabilistic drought risk analysis
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 […]
As our climate warms, the pressures on global forest ecosystems from extreme climate events are expected to increase across much of the world (Anderegg et al., 2020; Brodribb et al., 2020). Of particular concern is the increasing threat to tree health and productivity posed by drought. Despite a predominantly cool maritime climate, forest ecosystems in […]
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 […]
Sitka spruce is the major conifer species in British upland forests and is predominantly managed as even-aged, single-species plantations with rotation lengths of less than 50 years using a “patch clear-felling” system. Evidence on the impact of clear-felling on the carbon, water and energy balances of plantation forestry is sparse and extreme weather events, such […]

This Information Note summarises the results of a series of experiments, including a synthesis of data from previous Forest Research publications, to provide information regarding recent advances in propagation of hybrid larch using cutting production systems.
This report details a series of five experiments which were initiated to investigate the development of multiple leaders following simulated browsing/weevil damage to three size classes of Sitka spruce and Japanese larch immediately after planting.
NERC GREENHOUSE Project (2013-2017) FR were partners in the NERC GHG Emissions and Feedback programme where we contributed to measurements of the effect of forest management on GHG emissions and uptake. The project title (Generating Regional Emissions Estimates with a Novel Hierarchy of Observations and Upscaled Simulation Experiments) looked at the emissions and uncertainties in their estimates as we scale up from point measurements on the ground to the UK scale and the atmosphere above it.
Mike chairs the Climate & Carbon Working Group of the Sustainable Forestry SCIO (previously the Scottish Forest Alliance). The Sustainable Forestry SCIO is a £10m BP led partnership, has undertaken to monitor forest uptake of carbon on its sites for 200 years. Mike leads the development of the Alliance climate science in understanding the role of these new native woodlands in carbon sequestration.
Mike leads for Forest Research on afforestation carbon and climate mitigation benefits for Climate eXchange Centre and has input to expert reviews on Scottish Soils and Carbon.
Mike was the Forest Research lead in a recent NERC Knowledge Exchange ‘Forest-Finance Risk Network’. The project developed a network aimed at providing a stable investment environment for forestry, through the assessment of risk to forest assets.
Mike led the Forest Research contribution to the recent update of the Scottish Government guidance for “Calculating Carbon Savings from Wind Farms on Scottish Peatlands – A New Approach” and improvements to the assessment tool Carbon Implications Of Windfarms Located On Peatlands – Update Of The Scottish Government Carbon Calculator Tool. The project was led by Dr Jo Smith (University of Aberdeen) and Forest Research contributed expertise on forest management, forest carbon and wind flow aspects.
For the Climate eXchange Centre, Mike is leading work on assessment of net deforestation due to windfarms.
Mike led the Forest Research contribution to The Ecosystem Land Use Modelling and Soil Carbon GHG Flux Trial (ELUM) project, a £3.28m study commissioned by the Energy Technologies Institute (ETI), to produce a framework for predicting the sustainability of bioenergy deployment across the UK.
