Back in 1975, the American Grizzly bear was declared endangered. With only minor differences, the American Grizzly bear is the same species as the European bear, that lives from Western Spain, through Europe to the Kamchatka bear of far Eastern Russia.
In 1975 the USA lower 48 states grizzly bear population numbered somewhere between 136 animals and 312, so it was essential that it was protected. Nowerdays the same 48 states have a population of around 1500, but given that this number would have been as high as 50,000 when people started migrating to the USA in large number, this recovery is only just getting going.
If you follow this blog regularly, you will have read yesterday and the day before on the reasoning for reintroducing Lynx and Wolves.
As I wrote, Lynx should be a simple choice. I believe that Wolves follow a similar logical route, that suggests that the reintroduction would either save or make far more money that any negatives might cost.
Bears are also locally extinct in the UK, how does the arguments about reintroducing them go? Well, I would argue that actually the cost of bear reintroduction would be significantly lower.
Back around the 1900 there were around 1000 bears roaming the mountains of the Iberian peninsular. Unfortunately by 1950 this population had been reduced to two small populations consisting of 50-60 in one and perhaps as low as 14 individuals in the other.
