Herbicide Alternatives Program

A drive to 0 use of herbicides on sustainable forest Licenses.


The sharing of Indigenous knowledge to develop new approaches from Forest Management through to free-to-grow.

The Herbicide Alternatives Program (HAP) was established in 2010 by
Indigenous representatives and Tembec (Rayonier Advanced Materials- RYAM until 2021 now GreenFirst Forest Products) to identify and apply alternatives to the use of herbicides on company Sustainable Forest Licenses (SFLs) in northeastern Ontario.


With a priority focus on the Chapleau Crown Game Preserve and the Gordon Cosens, Romeo Malette and Martel Forests, significant reductions in herbicide use were targeted. The evolution of HAP includes the sharing of indigenous knowledge, modification of existing silvicultural techniques and application of LIDAR as examples of new approaches from Forest Management Plan development through to free-to-grow. In 2019, Natural Resources Canada joined Wahkohtowin and Green First to expand the reach and capacity of the initiative.


We've compiled useful resources for consideration and learning about HAP, our ongoing efforts, and how to get involved as a supporter.
