Every hairy, knuckle-dragging Neanderthal pi$$ing and moaning about "The Feds trying to protect a dumb fish or a dumb owl" which was threatened because of logging and deforestation and the silting up of the watersheds because treeless slopes lose their soil which covers the gravel which most breeds of fish need to spawn, particularly Pacific Salmon. And Pacific Salmon feed on what exactly when they reach fresh water?? Think it might be the Snail Darter on their way up the rivers to breed and lay their eggs and die?? Duh.
(Please note, that "Duh" is not directed at you, Bob, but at some who might have skipped the lesson in high-school about Pacific Coast ecology and the inter-connected web of the West Coast.)
If you lose the salmon you lose the forests. For 15 thousand years or more, the salmon have been caught by Grizzlies and Brown Bears as they go upstream to spawn. Grizzlies and Brownies are messy eaters, they may eat only about half of the fish they catch, but the fish rot down to replenish the soil with nutrients. They do it so well that you get some of the biggest trees in the world from that interaction. Now California has its endangered Redwoods (Sequoia) but no healthy salmon population or healthy Grizzly population to cause the replenishment of the soil, and the fragile giants, once they've lost the surrounding trees which protected and supported the largest at their centre, have a tendency to be damaged by high winds. The tops snap off.
They have done some great DNA studies which prove the interaction of the Salmon, the Grizzlies, and the trees. They can trace salmon DNA both in bear scat and in the cells of the trees apparently.
As I understand it, the US Salmon fishery is pretty much dead, except for the boats that come up the coast to fish in Canadian Waters. The Canadian fishery is, I hope, stable but usually the first warning sign of a crash in fish stocks, is ... a crash in fish stocks. There's not a lot of warning, or at least not a warning people whose livelihood and much costly equipment is bound up in the fisheries are willing to recognize. The Atlantic Cod Fishery is dead as a doornail, cod stocks are not rebounding.
Canada has a remarkably strong environmental record. The Black-Footed Ferret was rescued from extremely low numbers and has been re-introduced to the prairies. The Burrowing Owl, also on the brink of extinction has been reintroduced to the prairies to continue keeping the gopher population in check (that's not why it was reintroduced but it's the effect of reintroducing both the Ferret and the Owl.) The Black-Footed Ferret was down to 122 individuals, or so my old National Geographic used to tell me on the back page. I don't know how low the Burrowing Owl got but I'm reasonably certain it was about 50 individuals. Once people figured out that having the Whooping Crane around was kind of nice they too were brought back from the verge of extinction. There were just 27 individuals of that species at one point.
There is still a programme here since Canada is the breeding ground which pinches Whooping Crane eggs, and sticks them under the vastly more common Sandhill Cranes to be raised, forcing the Whoopers to lay new eggs which they do when the first lot is taken. Double the number of young reared each year. There has been a major programme as long as I've been here to re-introduce the Swift Fox to the Prairies, spear headed by an English woman who has devoted her life to saving the species. The young of both the ferrets and the foxes were particularly vulnerable in their first year to predation by large Hawks and Golden Eagles. Their first few months are lived under a wire canopy which keeps the hawks at bay until they bulk up and get some smarts, after that, they're moved to various sites to re-inhabit all across the Prairies which is 3 large Provinces.
