Trees for the Future

John Grimshaw - Director, The Yorkshire Arboretum 

6.00pm Tuesday 29 September 2020 by Zoom webinar 

John will explore the need to plant a diversity of trees to help bring resilience to our treescapes in the face of climate change and the threats posed by pests and diseases. Facing these challenges, which have in-built uncertainties, while also responding to governmental calls for massive tree planting across the country,  foresters and other tree planters need to embrace diversity, rethink silvicultural practices, and use a scientific approach to the selection of trees for their areas with regard to both species and provenance. With over 3000 tree species in cultivation in the British Isles, there should be plenty to choose from.
