In the most southern regions of Sweden, deciduous trees are dominating and among these for instance oak, beech, ash and elm are more common in the south. Uppsala is situated in one of Sweden's agricultural regions, and the area around Lake M laren has a relatively mild climate allowing many southern species to thrive there. In the middle and northern parts of the country, bears, lynx, some wolverines and a few wolves are living in the forests and in the mountains, though they are shy and only few people ever get a chance to see them. An unpleasant animal that is common in Sweden is the tick, a small, spider-like creature that attaches itself to mammals, including humans, to suck blood. It does not hurt to be sucked, but the tick may transfer some unpleasant diseases.
Ticks are especially common in tall grass and other dense vegetation.
When you find a tick on your clothes or moving on your skin, just take it away. If it has attached itself, it is important to remove it in the right way so that not parts of it remains. To transfer disease, the tick needs to be attached for more than 24 hours, so there is no reason to panic, but it is wise to check your skin carefully every evening after being out in the field, and if some tick has attached itself, ask for help to remove it. Compared to most countries in the world, Sweden has a long history of peace and democracy. Sweden has not been in war since 1815.
