This article presents five challenges facing citizen science use for detecting early tree health issues.
The early detection of tree health pests and disease is an important component of biosecurity to protect the aesthetic, recreational and economic importance of trees, woodlands and forestry. Citizen science is valuable in supporting the early detection of tree pests and diseases.
Different stakeholders (government, business, society and individual) will vary in their opinion of the balance between costs and benefits of early detection and consequent management, partly because many costs are local whereas benefits are felt at larger scales. This can create clashes in motivations of those involved in citizen science, thus leading to ethical dilemmas about what is good and responsible conduct for the use of citizen science.
This study draws on the authors’ experience of tree health citizen science to exemplify five dilemmas. These dilemmas arise because:
Effective engagement and dialogue across stakeholders, including public stakeholders, is important to properly address these issues. This is vital to ensure the public’s long-term support for and trust in the use of citizen science for the early detection of tree pests and diseases.
