A lover of animals since he was a child, Treadwell decided to travel to Alaska to watch bears after a close friend persuaded him to do so. According to his book,
Among Grizzlies: Living with Wild Bears in Alaska, his mission to protect bears began in the late 1980s after he had survived a near-fatal
heroin overdose. He wrote that after his first encounter with a wild bear, he knew he had found his calling in life, and that his destiny was entwined with those of the bears. He attributed his recovery from drug and alcohol addictions entirely to his relationship with bears. Treadwell spent the early part of each season camping on the 'Big Green', an open area of
bear grass in
Hallo Bay on the Katmai Coast. He called the area the "Grizzly Sanctuary". He was known for getting extremely close to the bears he observed, sometimes even touching them and playing with bear cubs. In his book, he claimed that he was always careful with the bears and actually developed a sense of mutual trust and respect with the animals. He habitually named the bears he encountered and consistently saw many of the same bears each summer and thus claimed to be building a standing relationship with them. which describes Treadwell's adventures on the
Alaska Peninsula. Treadwell and Palovak founded Grizzly People, an organization devoted to protecting bears and preserving their wilderness habitat. Treadwell claimed to be alone with the wildlife on several occasions in his videos; however, his girlfriend, Amie, can be heard behind the camera in much of the footage he took for his documentary during his last three summers. Other women Treadwell dated, who have remained anonymous, also accompanied him on some expeditions. Naturalist
Charlie Russell, who studied bears, raised them, and lived with them for a decade in
Kamchatka, Russia, worked with Treadwell. Russell advised Treadwell to carry
pepper spray and use
electric fences. After
Werner Herzog's documentary
Grizzly Man was released, he wrote a lengthy critique of Treadwell's failure to follow basic safety precautions. In spite of his criticism of Treadwell, Russell praised him for his devotion to bears and his ability to remain alive for so long. He defended him against people who criticized his work, writing, "If Timothy had spent those 13 years killing bears and guiding others to do the same, eventually being killed by one, he would have been remembered in Alaska with great admiration." Russell was critical of
Grizzly Man, saying it was unfair to Treadwell, and if Palovak "really was a protector of bears, she should have looked for a filmmaker who would have been sympathetic towards them." == Death ==
