As Director of Programs at ReForest London, Amber Cantell is responsible for helping set strategic direction for the organization and developing new programs to increase tree planting in London. She talks about some of the fundamental implications of climate change and what our rapidly changing climate will mean for London's trees. Will trees be able to keep up with the increase in heat and extreme weather? What will our forests look like in the future? How might assisted migration strategies be used to help our forests adapt, and what can we as caring citizens do to help?
