Acetamiprid used to prevent Hylobius abietis damaging young trees poses a very low risk of causing water contamination provided good forestry practices are followed

Lead Author: Huw Thomas
A study of chemical runoff following the use of acetamiprid as a pre-treatment and top-up spray to prevent damage from the large pine weevil (Hylobius abietis L.) to young trees was undertaken at a restock site in mid-Wales. The site was specifically selected to pose a high risk of chemical runoff, being a high elevation, […]

An analysis of conifer experiments in Britain to identify productive alternatives to Sitka spruce

Lead Author: Victoria Stokes
An analysis of relevant species trials was carried out to assess the productivity of potential alternative conifer species to Sitka spruce on upland site types in Britain. Data from 87 forest experiments planted between 1929 and 1995 were analysed to compare long-term performance of 52 species with that of Sitka spruce under the same conditions and site type.

Intimate mixtures of Scots pine and Sitka spruce do not increase resilience to spring drought

Lead Author: Tom Ovenden
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 […]

The potential of the selective graminicides cycloxydim and propyzamide as habitat improvement tools for the pearl-bordered fritillary butterfly

Lead Author: Matt Parratt
The pearl-bordered fritillary (Boloria euphrosyne) is a resident UK butterfly which is in decline, partly because grasses can outcompete its preferred food plant, common dog-violet (Viola riviniana). We therefore investigated whether using graminicides could help to enhance the habitat quality of a violet-rich butterfly ride. Applications of 1.5 kg a.i. ha-1 propyzamide or 0.45 kg a.i. ha-1 cycloxydim both reduced grass cover and were associated with an increase in violet plants. Our work suggests that enhancing pearl-bordered fritillary habitat may not always be possible through herbicide use alone, but cycloxydim may have a useful role in helping to reduce competition from grasses.

Threshold Response to Extreme Drought Shifts Inter-Tree Growth Dominance in Pinus sylvestris

Lead Author: Tom Ovenden
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 […]

Life after recovery: Increased resolution of forest resilience assessment sheds new light on post-drought compensatory growth and recovery dynamics

Lead Author: Tom Ovenden
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 […]

Comparison of the carbon, water, and energy balances of mature stand and clear-fell stages in a British Sitka spruce forest and the impact of the 2018 drought

Lead Author: Georgios Xenakis
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 […]

The devil is in the detail: Metabarcoding of arthropods provides a sensitive measure of biodiversity response to forest stand composition compared with surrogate measures of biodiversity

Lead Author: Nadia Barsoum
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.

Using genome resequencing to investigate racial structure, genetic diversity, sexual reproduction and hybridisation in the pine pathogen Dothistroma septosporum
Genome sequencing is used to determine the origins and genetic diversity of Dothistroma populations throughout the UK, and confirms the findings of our earlier paper discerning population structure with microsatellite analysis.

Are there viable chemical and non-chemical alternatives to the use of conventional insecticides for the protection of young trees from damage by the large pine weevil Hylobius abietis L. in UK forestry?

Lead Author: Ian Willoughby
In UK forestry, the synthetic pyrethroid insecticides alpha-cypermethrin and cypermethrin have been used for many years to provide protection for young trees planted on restock sites from damage by the large pine weevil, Hylobius abietis L. However, concerns over the toxicity of these insecticides to aquatic life if misused has led to a search for alternative forms of protection. This paper describes a detailed programme of efficacy experiments undertaken between 2009 and 2014 to find replacements for these products. Over 50 combinations of chemical and non-chemical approaches were tested on 16 different sites.
