It is very important to work closely with companies working on your trapping area. The companies will cooperate, and working together gets good results, reducing expensive conflicts and hard feelings.
When conflicts occur and can’t be resolved, provide all details to the Fish and Wildlife Office and have a claim prepared. The claim will then be forwarded for review to the ATCB. If the ATCB finds the company responsible, they will advise them to settle the claim with the trapper.
Due to extensive forest harvests and oil and gas activity (seismic/drilling, etc.) long-term loss of income claims are being reviewed by the ATCB. They require a very comprehensive review, and trappers need to provide a great deal of information (i.e. maps, photographs, fur harvest records, etc.). Consult with your Fish and Wildlife Officer, who will prepare the claim on your behalf.
