This is the assessment by trackers and wildlife experts in a new report produced by Sweden's regional authorities.
Their conclusion goes against a report compiled by scientists for the World Wide Fund for Nature (WWF) which states the illegal hunt has become noticeably less frequent since 2005.
Since 2006, WWF puts the official count of killed wolves between three to seven animals. Critics disagree.
"In the last six years about 50 wolves have disappeared only in Gävleborg and Dalarna districts. The poaching hasn't decreased, it's the opposite," says Mats Rapp, wolf tracker at the regional authority in Dalarna to the newspaper Expressen.
The authors of the contradictory reports are now set to meet to go through their findings, reports the news agency TT.
