From Fatal Car to Moose Collisions:
In Sweden, the number of moose vehicle collisions (MVCs) were 5874 in 2016 (Nationella Viltolycksrådet 2015). During the last 10 years in average 5 [human] fatalities occur annually due to MVCs in Sweden.
To put this in proportion, see Sweden Sverige (emphasis added):
There are approximately 350,000 moose (Alces alces) in Sweden.
- If a moose feels cornered, it sometimes lowers its head and rushes towards people.
- Every year there are approximately 6,000 road accidents involving moose.
- Each year about 100,000 moose are killed during hunting season in Sweden.
- If you just want to watch moose, not hunt them, you can go on a "moose safari"
The actual numbers of reported collisions vary from year to year and source to source. According to research done at The Sivis Lab, which focuses on sustainability and conservation,
In Sweden, moose are a national symbol, a major game species, and a hazard for car travel, with some 4,500 accidents per year. [year not given] (emphasis added)
Only 285 people were killed in road fatalities from all causes in 2012, according to The Local SE. The only data I have been able to find so far on moose mortality from MVCs dates from 1980 (from The toll of the automobile:
Wildlife and roads in Sweden by Andreas Seiler:
For example, approximately 92% of all moose and 98% of all roe deer
involved in police-reported vehicle collisions in Sweden ultimately
died as a consequence of an accident (Almkvist et al. 1980).
Swedish traffic became much more dangerous for moose in the 1970s: a report from 1986 Collisions with Passenger Cars and Moose, Sweden stated:
In Sweden, the number of reported road accidents involving large wildlife and motor vehicles has increased five-fold during the 1970s and now constitute about one third of the accidents on the state road net (i.e., excluding rural roads). It can be calculated that about one driver out of 10 with an annual driving distance over 20,000 km will collide with a moose once during his lifetime.
But this trend may be reversed. According to Wired new technology debuted in 2017 "to help save the Swedes meatballs":
[Volvo's] new Large Animal Detection system can spot and identify outsized carbon-based hazards and stop the car before colliding with moose.....
Sustainability of the Moose Population
Source: Hunting for Sustainability: A Summary of Research Findings from Sweden. This source summarizes the management of the moose population in in Sweden and is part of a larger project funded by the European Union’s 7th Framework Research Programme. Hunting appears to be conscientiously regulated in Sweden with due regard for the management of game populations. However, I am not knowledgeable enough to critique this report. Of the ungulate populations in Europe (not just Sweden) the report says:
Some countries, where the total ungulate population has increased to its highest level since the Ice Age have raised a general concern for negative ecosystem impacts due to overgrazing.
Contribution of Moose to the Swedes' Diet
The majority of moose hunted are hunted for food. Hunting for Sustainability says:
The support for hunting among the public in Sweden is strong. There is
thus a wide acceptance for hunting, in terms of wildlife management
but also as a way of providing food. The support for ‘pure‘
recreational hunting is however lower.
This is only a qualitative comparison, but let's assume that all hunted moose wind up contributing to the diet of the Swedes.
One can expect to get 312 pounds of meat from a moose. Source: Pourvoiries du Québec. That is 31.2 million pounds of moose meat per year from hunting, for 9.9 million Swedes, or 3 pounds per Swede or 12 Moose-Quarter-Pounders per year per Swede.
