Urban Forestry and Biochar

March 31, 2021 – 12:00 – 1:30 pm ET (US)

More and more cities are adopting the use of biochar in urban forestry practices since the Stockholm Biochar Project first pioneered the practice many several years ago. The benefits have long since gone beyond extending the life of urban trees to improving stormwater management. This webinar will present new perspectives on the benefits of biochar use in urban environments.

Henry Kuppen, an arboricultural consultant, and Managing Director of Terra Nostra, has been conducting research related to tree growth with biochar for the past three years. He will discuss various case studies outlining the use of biochar in planting new trees, transplanting of a nearly 100 year old trees and improving the growing environment of mature trees in Dutch metropolitan areas.

Minneapolis, MN has become a leader in urban uses of biochar thanks to the efforts of Jim Doten. Under Jim’s guidance biochar has been used to restore trees stressed from road salt, and to filter E.coli and PFAS contaminants.  He has worked in collaboration with researchers at the Natural Resource Research Institute to understand biochar variability for different end uses. Jim will discuss the experiences to date as well as Minneapolis’ future plans for local biochar production.
