We investigated whether biodiversity information obtained from DNA metabarcoding of mass-trapped arthropods and from a range of taxa-based surrogate measures of biodiversity (e.g. carabid beetles, vascular plants) provide: 1) similar estimates of alpha and beta diversity and 2) provide similar forest management related conclusions. We also explored how well habitat-based surrogate measures of biodiversity (e.g. stand structure, volume of deadwood) predict observed biodiversity patterns.
• Novel dendrochronological modelling was developed to explore oak stem growth trends.
• Trees with long-term AOD symptoms may have been predisposed many decades earlier.
• Diseased trees struggle to take advantage of favourable growing conditions.
• Historic episodes of stress may impact the future resilience of oaks to disturbance.
More biodiverse woodlands are better able to resist or adapt to threats, such as climate change. This enhanced resilience supports the continuity of woodlands and the ecosystem services they provide. Biodiversity is the variation at different levels of biological organisation - the genes within a species; the species within a community; and the diversity between communities and ecosystems.
This paper stresses that future use of ‘alternative’ species for diversification should be contingent on rigorous biological risk assessment, results from forestry scale trials, and the establishment of sustainable British seed sources.
This Research Report provides a review of published results from provenance tests of relevance to English native trees to identify factors which may influence the risk, suitability and desirability of the use of local versus non-local seed under climate change.
Exposure to a contrasting novel environment such as waterlogging under common garden conditions can trigger release of otherwise unobservable (cryptic) genetic variation. Under a flooding treatment, there was a greater increase in variability in Scots pine populations originating from drier sites in Scotland which likely reflects a relative absence of past selection. Under climate change this cryptic genetic variation may provide considerable potential to adapt.
Black poplar is Great Britain’s rarest native hardwood and there is considerable interest in conserving the genetic diversity present in the remaining population. However, multiplication by vegetative propagation has led to issues in identifying and selecting genetically diverse native planting material. The ability to use DNA markers to identify poplars at the level of the […]
Growing threats to biodiversity from pressure of land use, climate change, and invasive pests and diseases highlight the importance of obtaining accurate baseline measurements of current forest biodiversity, as well as improved monitoring to detect early signals of change. Developments in molecular techniques have advanced to the stage that there are now practical methods available […]
Paper explores challenges faced by the nursery sector in Great Britain in an era of environmental uncertainty In recent years, there have been many studies exploring the management strategies that might be used to enable our forests to better cope with climate change. However, these seldom take into account the practical and economic implications of […]
Study finds twinflower in Scotland exhibits genetic effects of chronic population fragmentation Habitat fragmentation is widely thought to contribute to the decline of plant species. In part, this is due to the restriction it places on the flow of genes (which occurs through pollen and seed dispersal) within a plant population, creating sub-populations within which […]
Conserving the genetic diversity within our tree species and the processes that determine it are important for sustainable forest management and increasing the resilience of Britain’s forests and woodlands. The genetic diversity within a tree species at any one time is the result of many dynamic processes, and it provides the source for future adapted […]
As part of a UK–India collaboration on forestry, this summary report shows how Forest Landscape Restoration can safeguard biodiversity by taking a landscape approach using appropriate technologies and practical applications and produce real benefi ts for communities by working in partnership with them. Edited by Mike Smith (Forest Research) and Sandeep Tripathi (India Forest Research […]

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.
A range of biotechnological tools has been used by Forest Research to enhance the efficiencies of research and development programmes associated with tree breeding and genetic conservation. This Information Note presents some examples where such tools have been applied. These include enhancement of flowering in conifers, assessment of the efficiency of seed orchards, characterisation of […]
