In Stockholm County, about 6,500 wildlife accidents occur annually.
Most, three out of four, are deer accidents, according to the National Game Accident Council.
In total, the number of accidents with deer has increased by 50 percent in five years, according to the insurance company IF.
But the population of wild boar and fallow deer has also increased.
The County Administrative Board's explanation is that the animal populations have grown but also the growing city.
- Even if a new heavily trafficked road is built and crosses the path, the animals do not change their routines, says Tobias Hjortstråle at the County Administrative Board in Stockholm.
5,000 hunters in the public service
On behalf of the state, the Swedish Hunters' Association has organized 5,000 hunters all over Sweden who are ready to help when wild animals are injured in traffic.
76-year-old Göte Åberg is one of them.
He annually shoots between 20-30 animals that have been hit along the roads where he lives.
- The police give me the number of the person who reported the animal that was hit.
It makes it easier for me so I can find the accident site and determine how injured the animal is, says Göte Åberg.

Kenneth Kronberg is the police responsible for wildlife in Stockholm County and coordinates hunters for searching for animals that are injured in traffic.
It is a crime not to report a wildlife accident to the police
Since 1 January 2010, there has been a duty to report to the police in the event of a collision with larger wild animals.
It applies to bears, wolves, wolverines, lynx, moose, deer, roe deer, otters, wild boar, mouflon sheep and eagles.
But the dark figure for how many people ignore reporting accidents is large, according to Kenneth Kronberg, who is the county police responsible at the National Game Accident Council in Stockholm.
- If it is a larger animal, it is classified as a contagion accident if you do not call the police so that wanted hunters can search for the animal, he says.
