Tree Measurement and Identification

Trevor Clark and Gavin Markwart, forestry technicians, explain how to estimate board feet in standing timber. They discuss measuring tree height and diameter using tools like calipers and diameter tape. The Ontario Log R is introduced for estimating board feet based on tree dimensions. A conversion from cubic meters to board feet is provided. A practical demonstration on measuring tree volume is conducted at Fleming College, highlighting the use of resources like the Ontario tree marking guide.
