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.
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,...
• 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.
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...
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.
The grading, and therefore the ultimate value of construction timber is governed by the mechanical properties of strength, density and stiffness.
The majority of British spruce timber is graded as C16 but has density and strength characteristics which are usually high enough to achieve greater grades. The factor limiting a greater...
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 […]
A collaboration between Forest Research, Oxford University and Roslin Institute (University of Edinburgh) which will use DNA-marker technology to identify at a very early age those Sitka spruce trees which will have outstanding growth rate and timber quality when felled 30-years later
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 […]
