About the Grant
The Jack Kimmel International Grant Program is a significant initiative managed by TREE Fund in collaboration with the Canadian TREE Fund. Established in memory of Jack Kimmel, a renowned arboriculture leader and former Director of Parks for the City of Toronto, this grant commemorates his 46 years of service to the International Society of Arboriculture and its Ontario chapter. The program aims to support international researchers working on impactful projects in arboriculture and urban forestry. Open to researchers based outside the United States, the grant offers critical financial assistance for innovative studies that benefit the broader tree care community. Each project funded under this program is expected to contribute meaningful insights into urban forestry practices or arboricultural research. The evaluation process involves representatives from both TREE Fund and the Canadian TREE Fund to ensure a high standard of selection. Projects must be completed within one to two years, with funding determined by the assessed value and relevance of the proposed work to global arboriculture challenges.
