A project was commissioned to estimate and compare the potential for carbon sequestration (net CO2 uptake) and GHG emissions mitigation that could be realised by creating different types of woodlands.
The analysis assesses the influence of different tree species, site and management factors, including the eventual use of harvested wood, on...
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...
Forest Research have been engaged in efforts to improve tolerance of ash trees to ash dieback caused by Hymenoscyphus fraxineus (previously known as ‘Chalara‘) since the disease was first recognised in Great Britain in 2012.
Progress has been made under three main projects:
Living Ash Project
Ash dieback mass screening trials
Testing a range of ash species for tolerance to ash dieback
Across these three projects,...
This is a collaboration with tree health scientists to explore new and emerging pest threats to priority tree species and new woodlands. We aim to assess the risks posed by established pests under current and future climates, and the most likely invasion pathways for key invasive pests.
This research aims to determine the practicality, durability, and efficacy of non-plastic biodegradable treeshelters and other tree protection methods, as alternatives to using treeshelters made from conventional plastics.
LAP2 commenced in 2019 as an extention of the earlier Living Ash Project phase I.
The objectives of LAP2 are to:
Establish a National Archive of Tolerant Ash based on selections made in the Living Ash Project phase I and from Forest Research's mass screening trials (Future Trees Trust)
Intensively screen selected trees using...
Forest Research, Forestry & Land Scotland and Forestry England have co-developed an evidence based, repeatable approach for assessing the biodiversity potential of the National Forest Estate. Several extent, condition, connectivity and diversity metrics are measured and aggregated into a Combined Biodiversity Index. An online, interactive tool allows users to explore mapped scores.
How do we manage insect pests in forestry? This PhD project aims to evaluate current science and practise and develop and test new and improved methods in order to enhance integrated pest management in the industry.
How do contemporary Great British attitudes to urban trees vary between locality, individuals and communities with different socio-demographic backgrounds? Forest Research aims to investigate this through a rapid evidence review, a national questionnaire and a series of focus groups.
Managing woodland stands in a way that retains productivity targets, but that also fosters biodiversity and stand resilience are key sustainable forest management goals. Current forestry policy advocates a diversification of woodland stands to achieve these goals, favouring mixed age structures, trees of mixed provenance and polycultures over...
Forest Research has recently examined some long-term experiments to examine provenance variation of emerging species. Individual reports for the species covered so far can be found here. The table at the bottom of this page is a summary of how the results compare with Forestry Commission Bulletin 66, which only...
Using tree ring measurements (dendrochronology) and stable isotope analysis, the research aims to examine the stem growth and tree health histories of Acute Oak Decline (AOD)-affected trees, to look for evidence of predisposition to AOD, the impact of AOD on recent growth, and correlation with A. biguttatus attack.

Forest soils contain large amounts of carbon, which can be lost through forest operations or changing environmental conditions. As forests are perennial with infrequent disturbance, soil organic carbon (SOC) accumulation differs from highly disturbed land uses, with significant accumulation occurring in deeper soil horizons...

This study investigated selected root traits such fine root length, belowground fine mass (biomass and necromass) distribution across different root diameter classes and soil depths, and patterns of temporal dynamics in root biomass and necromass.

Northern temperate forests have been identified as major contributors to the terrestrial C sink. Among the different land uses, afforestation and reforestation have been recommended as practices to mitigate climate change by promoting C storage in both soils and biomass but the main factors...

Forests are crucial for biodiversity and also provide numerous ecosystem services that enhance human welfare. However, when studying forests, often the complexity of life belowground either goes unnoticed or it is studied in isolation from its aboveground component. Compartmentalising the above and belowground...
A multi-partner Europe wide transdisciplinary project to understand the large-scale diversity and distribution of ectomycorrhizal fungi across Europe, taking into account long-term monitoring of environment, climate, soil and geographical variables.
Management of oak processionary moth (OPM) is becoming an increasing challenge to land managers of trees and woodlands in urban and rural areas as the pest continues to spread outwards from original infestation sites in London. This work looks at how landowners and other managers of trees are responding to...
