The environmental concern isn't "bottle necks", its extinction.
Extinction is alot more likely when a population is decreasing rapidly and its numbers are close to where normal mortality has a good chance to result in extinction.
Maybe the small numbers of spotted owls will result in the entire species undergoing rapid genetic drift and changing their traits, like nesting somewhere besides old growth snags. Thats or extinction is what the advocates of clear cutting are hoping for.
I'd say that Humboldt's population has been prety small and isolated and the locally born here show the effects of genetic drift in a reduced ability to reasona and think.
