Sweden : Opener

Update from our Sweden bear volunteer project

It’s time for our 2025 edition of our Sweden bear expedition, working in collaboration with Björn & Vildmark (bear & wilderness). I am Matthias Hammer and I will be your expedition leader this year.

This is our fifth citizen science research expedition in Dalarna province, Sweden, gathering field data on brown bears (Ursus arctos), contributing to the conservation of this iconic Scandinavian mammal. The data collected is used by the trans-national Scandinavian Brown Bear Research Project (SBBRP). Expedition scientist Dr Andrea Friebe has worked in the SBBRP since 1998 and wrote her master thesis and dissertation about brown bear hibernation and ecology in Sweden.

The main focus of the Biosphere Expeditions brown bear research expeditions is locating and surveying winter dens used by bears that have previously been fitted with tracking devices. Once the bears have left in spring, each winter den is then carefully measured by the citizen scientists and a wide range of data are collected relating to the type of den, the surrounding habitat and any evidence of cubs and/or bear scats at the den site. The data gathered by the expeditions are used by the SBBRP as part of their long-term research programme following the lives of specific bears from birth to death, to gain insights into bear diet, weight development, patterns of movement, colonisation of new areas, choice of den, social behaviour, mortality and reproduction. Inter-species interaction with moose and domestic livestock have also been investigated, as well as the sensitivity of bears to human disturbance and human-bear conflict. The purpose of this all this is to provide managers in Norway and Sweden with solid, fact-based knowledge to meet present and future challenges by managing the population of brown bears, which is both an important hunted species and a source of conflict, and whose management has been changing rapidly in recent years.

So, here we are. I hope you have read the latest expedition reports, your preparations are going well and you are all excited. I will be a few days ahead of you and my next diary entry will be from Sweden with updates from the ground.
