If and when they do that we will find a way to adapt and detect. The beauty of a real-time system is that you can make changes/improvements remotely without having to go out in the forest again and swap devices out.
In fact, the forest is a very loud place and yet we are still able to detect the sound signature of a chainsaw.
I was thinking and wondering how reasonable as a "next step" in protecting forests to potentially require GPS tracking on all or certain types of chainsaws - it feels like an absurd thought on its own, though it potentially helps solve the problem.
This could then extend tracking to imagery via satellite - via geographic and density changes being detected, knowing where the GPS-tracked and legal work was being done, being able to then eliminate those areas from as high of scrutiny. Perhaps the GPS tracking is then not necessary if you can accurately compare before/after imagery, though could be a useful tool anyway for management to know how efficiently equipment is being used, if it's at where it should be and such.
This reminded me of a story my father once told me. I assume he heard it because his father was part of the Ministry of Forest in Canada a long time ago: I believe it was during a world war (not sure which one) when I could imagine lumber would have been in constant demand. There was a bit of a trick and literal loop-hole that truckers would use. Before being discovered there apparently was a long route where truckers would go through without actually dropping off their lumber - after having gone to the weigh-in point to get paid. They'd continue to drive through the back to return another day with the same load to get paid again; a long drive apparently but still was a money maker..
