This project aims to establish a network of genetic conservation units (GCUs) across the natural range of European tree species to conserve the genetic diversity of forest genetic resources (FGR).

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.
Booklet describing the contribution of woodlands to promote sustainable development within the regional Structure Plan.
By Duncan Ray and Darren Moseley.
• 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.
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...
