Plants sustain nearly all life on Earth: protecting plants is thus protecting life itself. 2020 has been designated the International Year of Plant Health, and as part of this, Sibbaldia, RBGE’s peer-reviewed journal about the horticulture and related activities of botanic gardens and other heritage and conservation gardens and landscapes, has published its first ever Special Issue.

Number 18 is out now. All papers are connected with the subject of plant health and management of pests including pathogens. Climate change, the biodiversity crisis and a rise in the impacts of pests on landscape and livelihoods are interconnected. This volume is an opportunity to share research activity and solutions to these issues.
