'I'd like to report a suspicious looking tree': Public concern, public attention and the nature of reporting about ash dieback in the United Kingdom.

'Public concern', a ubiquitous notion used in descriptive and explanatory modes by policy makers, academics and the media, is often presented as axiomatic. However, the variability with which it is deployed in different contexts, for example, as justification for policy attention or having equivalence with what is considered 'newsworthy', belies this status. This article presents an empirical analysis of emails and phone calls from the UK public to UK government agencies, reporting suspected cases of ash dieback disease - a tree health issue which attracted intense media and policy attention in the United Kingdom in 2012.

Expert risk perceptions and the social amplification of risk: A case study in invasive tree pests and diseases.

The Social Amplification of Risk Framework (SARF) is often used as a conceptual tool for studying diverse risk perceptions associated with environmental hazards. While widely applied, it has been criticised for implying that it is possible to define a benchmark 'real' risk that is determined by experts and around which public risk perceptions can subsequently become amplified. It has been argued that this objectification of risk is particularly problematic when there are high levels of scientific uncertainty and a lack of expert consensus about the nature of a risk and its impacts.

Awareness, concern and willingness to adopt biosecure behaviours: public perceptions of invasive tree pests and pathogens in the UK.

The growing incidence of invasive tree pest and disease outbreaks is recognised as an increasing threat to ecosystem services and human wellbeing. Linked to global trade, human movement and climate change, a number of outbreaks have attracted high public and media attention. However, there is surprisingly little evidence characterising the nature of public attentiveness to these events, nor how publics might respond to evolving outbreaks and the management actions taken.
