Understanding public risk concerns: social perception, interpretation and communication of tree health risks TREE SPECIES SOCIAL & ECONOMIC FACTORS Tree species Extended phenotype Organisms associated with tree Phenotype All measurable traits of a tree Genotype Genetics of an individual tree varies with genotype, environment varies with genotype, environment Rationale Want to protect species, but: • • • Many different known pests / diseases Unknown threats Changing conditions Rationale Want to protect species, but: • • • Many different known pests / diseases Unknown threats Changing conditions So, increase resilience: • Reduce susceptibility: • Increase number of resistant genotypes allow adaptation • Reduce tree stress Match tree to environment • Find ways to manage this PROTREE Objectives Using Scots pine as a case study 1. Identify variation in 3 key threat species: • • • Present, widespread Present, localised Not present, potential 2. Measure variation in host tree species. 3. Find management options for increasing resilience.
