Trees are essential for functioning ecosystems, from the vital roles they play in carbon capture, air purification, and water storage to providing food and shelter for wildlife, as well as shading and cooling for humankind. Chelsea Physic Garden has 192 trees, of which 158 are different species, contributing to the biodiversity and beauty of London’s oldest botanic garden.

In 2022 we declared a microclimate emergency. Our ecosystem is at risk due to climate change. As the engines of ecosystems, we must first look to future proof our tree collection. Trees grow slowly so we must act fast to plan and plant trees that will adapt and survive in our changing climate.

The Garden is seeking funding to secure expert arboriculture and ecological advice to map our tree collection, generate climate science data, and create a future proof planting programme, which together will form a Tree Succession Plan.
