Ruth is a plant/soil research scientist at the James Hutton Institute with 20 years’ experience of working on a wide range of applied ecological research projects.  Her research focuses the impact of pressures such as grazing, pollution, land management and plant diseases on above and below ground biodiversity. Over the last five years Ruth and her team have developed expertise in assessing the wider ecological impacts of declines in plant health (notably ash dieback and oak decline) on biodiversity and ecosystem functioning.  In particular the team identify which other species only or primarily use the plant species impacted by the disease and if the plant species which may replace the diseased species provide suitable ecological niches for the same suite of biodiversity.  Ultimately the aim has been to provide practical advice to mitigate, as far as possible, the adverse impacts of plant diseases on the wider environment.


Project Lead: Katherine Hayden
Pests and diseases represent a major emerging threat to biodiversity, in part due to increased global trade, climate change, and wider habitat degradation. The potential impacts include direct threats based on pest/pathogen impacts on focal species, as well as wider secondary effects for other interacting species and communities.
Compared to threats such as climate change and habitat fragmentation, plant health issues are poorly represented in international and national biodiversity strategies such as the Aichi Targets of the Convention on Biological Diversity, the Global Strategy for Plant Conservation, and the Scottish Biodiversity Strategy. Work is thus required to provide strategic guidance on the inclusion of plant health threats into the next iteration of the biodiversity strategies.

Impact: Direct guidance and input for plant health issues into the new Scottish Biodiversity Strategy; best-practice example of plant health integration into national biodiversity planning (model for other countries).
