Following is an extract from a website update written by Barb Murray at http://bearmatters.com.
History was ‘officially’ made on Weds, May 16, 2007! A North American bear rehabilitor, Leona Green, has successfully raised 4 orphaned grizzly cubs (2 female), taking them from 15-20lbs in July ‘06 to their release weight of well in excess of 100lbs. The bigger size for their age class will give the cub’s a fighting chance with preditory carnivores. The cub’s diet consisted of high protein from donated venison and salmon, grains, veggies and fruit ( including natural berries previously picked and frozen). Leona Green has raised and released two female grizzlies in 1996 but they were not officially counted by the authorities at that time.
Grizzly bear rehabilitation is done in other parts of the world like Russia and Romania but North American authorities have been shy to embrace it for ‘liablity’ reasons ( I believe?). Thanks to some progressive and compassionate Conservation Officers in Northern BC Leona Green was able to help give these four cubs plus two black bears a second chance this year. She has now rehabbed over 100 bears successfully over 30years (not one of the bears have shown up and caused problems).
