Technical Summary
The project will take advantage of existing experimental resources that the consortium has been building for the past few years. These include living experiments (a reciprocal transplant experiment on 3 contrasting sites including 21 native provenances; a glasshouse provenance-progeny trial; field provenance-progeny and provenance trials) and genetic and genomic resources (a large database of mutations across the Scots pine genome and capability for high-throughput genotyping; reference genome for Dothistroma; genetic markers for Dothistroma and pine tree Lappet moth). These existing resources will be made available to the project at no cost.
We will assess distribution and variation in the threat organisms using surveys and genotyping, and study pathogen evolution by characterising genetic changes in samples from different populations. We will assess variation in the host using population genomics (high-density genotyping of samples from multiple populations in trials) and quantitative genetics (analysis of variation in phenotypic traits and extended phenotype - resistance, phenology, morphology, needle chemistry, needle endophyte community). Data from the biological studies will be unified in a spatially-structured database and used, with data on distribution, density and regeneration rates to model the introduction and spread of threat organisms and their interaction with a variable pine population. The models will be used to test scenarios for management change that emerge from stakeholder interactions.
We will use workshops, semi-structured interviews and focus groups with stakeholders (identified through stakeholder analysis) to identify, test and refine options for building resilient pine populations. This will be a dynamic process, with ongoing interaction between natural and social scientists in the consortium, and with stakeholders. Finally, we will create a template for extending the analysis to other tree species.

Description | We have discovered that the population of Dothistroma infecting pines in Scotland is composed of three races . There is an endemic, asexual and genetically uniform race (NPR) on native Scots pine populations that is of low virulence The large scale planting of two exotic pine species, Corsican and lodgepole pine, has introduced two more virulent races of Dothistroma. The Southern race (SR) from continental Europe is sexually reproducing and genetically variable and has caused huge damage, particularly on Corsican pine.The lodgepole pine race (LPR) has been introduced as a single fruit body from North America and has spread asexually causing significant losses in lodgepole pine plantations. Hybridisation has taken place between the introduced SR and endemic NPR races, greatly enhancing the threat posed by Dothistroma to native Scots pine populations. |
Exploitation Route | The outcomes of this funding have led to the removal of lodgepole pine plantations from the vicinity of native pine populations, and heightened awareness among policy makers of the biosecurity implications of introducing exotic tree species that are related to our native trees. |

Description | Implications of the presence of three different races of Dothistroma in Scotland, one of which may be endemic, are being incorporated into the current Dothistroma action plan. As a consequence of the research large scale programmes to remove exotic pine species from the vicinity of native pinewoods have been implemented by Scottish Forestry. The research has also provided a classic example of the biosecurity risks posed to native trees by the introduction of novel exotic species, and strengthened the arguments for thorough risk assessment before any new exotic tree species are planted on a large scale in the UK. |
