Proposed pesticide use in Miramachi Watershed causes conflict between government and indigenous groups

August 24, 2021

Sometimes, a given area is the setting for disputes over the environment. Such is the case with the Miramachi watersheds in New Brunswick. The Miramachi has recently been a setting for disputes between the government and indigenous groups.


The point at issue between the government and indigenous groups is the introduction of the pesticide rotenone into certain parts of the watersheds. The department of Fisheries and Oceans justifies use of the pesticide to control small-mouth bass, an invasive species. However, recent efforts to introduce the pesticide have been blocked by groups representing the indigenous community, who oppose the use of pesticides for environmental reasons.
