"The misinformation promulgated by wolf advocacy groups ranges from minor technical errors to major deception and fraud. Technical biological misinformation, though bothersome to professionals working with wolves, is not as serious as deception about such issues as the status and trends in wolf populations. This latter type of misinformation tends to motivate well-meaning wolf advocates to press their causes through letter-writing campaigns, public meetings, lobbying, and lawsuits. For example, animal welfare and wolf advocacy groups have been advertising for funds in major national newspapers for years, claiming that wolves were threatened in Denali National Park and other parts of Alaska, despite documentation to the contrary. These misrepresentations have even made it into conference proceedings. In the non-peer-reviewed proceedings of a nonprofit citizen organization, "Defenders of Wildlife's Restoring the Wolf Conference," undocumented claims were made the wolf has been eliminated from "95% of its former range" and "95% of its historic range in North America". The actual figures are closer to 30% of its global range and 40% of its North American range."
