Isn’t the reason for the lack of studies on Beaver dams because there is not a problem to study?
No. Beaver dams are recognised as a problem for salmonids by many sources and specifically by The North Atlantic Salmon Conservation Organisation (NASCO). As said above, Beaver dams, from a fisheries management point of view, are simply a class of instream structure, like weirs, fords, dams, etc. and need to be assessed in the same, quantitative, way (see 11 above) good fisheries management cannot therefore dismiss them without investigation.
