Treefarmer is a free web-based computer tool to assist landowners with woodlot planting and harvesting decisions.

Woodlot Planning

Multiple woodlots can be mapped on your property and the planting of five forestry species simulated. Choose from three tending regimes to give costs and yields (wood and carbon) for selected harvest age.

Tree Harvest

Multiple woodlots can be mapped, and the harvest planning simulated by drawing woodlot boundaries, skid locations and road scenarios.
Access to the tool is available from Forest Growers Research ».
