This document describes and reports on the first year of activities undertaken for the Welsh Plant Health Surveillance Network (WPHSN), a ground-breaking Welsh Government funded project to monitor native and invasive pests and pathogens that may pose a threat to health of plants and trees across Wales.
In this project we explored what hinders and enables researchers, policy makers and practitioners in their work protecting native trees and forests in New Zealand/Aotearoa and Wales/Cymru. This is an international collaborative project between the two countries called Post-colonial biosecurity possibilities.

First evidence of breeding by Ips typographus in the United Kingdom and expansion of Ips amitinus in Scandinavia, Ips duplicatus in central Europe and Ips cembrae in Great Britain and western/northern Europe suggest that factors that previously limited or moderated range expansion may be changing. This project will assess the...

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 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.
Milder and wetter winters, followed by increased spring rainfall, are likely to enhance the survival and infection potential of many tree pathogens. Hotter, drier summers leading to drought stress in trees will also increase their susceptibility to disease and expand the distribution range of some pathogens. The increased incidence and severity of diseases caused by Phytophthora species reduces the benefits that trees provide, including climate change mitigation.
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,...
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.

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.
