I'm really bad at managing the salmon populations too.

and the spruce tree population and the grouse population and the vole population and the squirrel population The list goes on.

Some need more attention than others.

Having as few species at record highs does not make a fur market, be it ranch or wild. It is good for those that have those species and for the most part those species are not harvested in huge numbers.
There are 10s of millions fewer ranch pelts and wild fur pelts bought and used today compared to even a decade or two ago, so to me that shows that the amount of resources committed to fur of any type is a fraction of what it was in the past couple generations. Will we have a fur market that goes down to the middle classes of the world in the future? We probably will but it sure is not here now. One of the reasons we see some upward movement in some of our more staple furs like rats, coons, red foxes etc. is that the prices of some of the luxury furs are so high that a bit trickles down to the utilitarian furs, but that too is extremely selective at this time.
