Client: MNR

The enhanced Forest Resources Inventory (eFRI) is a strategic survey of Ontario’s forests. The program is tasked with surveying 555,000 square kilometres of forest land and wetlands across much of Ontario.

It gathers a range of ecological information, tree species composition, range, age etc and, land use conditions. It is used to meet provincial, federal and international reporting requirements and, support resource management decisions.
