Field Excursion
3 September;
One day in Finnskogen -the forest of the Finns
Finnskogen is the westernmost part of the continuous taiga reaching through Sweden and Finland all the way through Russia to Vladivostok. Finnskogen got its name due to Finnish immigration starting in the 17th century. The forest is now an ocean of commercial managed forest with islands of protected areas with low human population density and varying populations of capercaillie, black grouse, hazel grouse and willow ptarmigan. We plan for good populations this autumn but can give no guarantee.
Thursday September 3 we will leave Hamar by busses, pass Elverum and stop at 3 locations in Finnskogen (see map), before we go back to Elverum where we will have a wildlife lunch and a self-guided visit at The Forest Museum https://skogmus.no/en before the great banquet at the hotel.
When arriving Finnskogen, there will be a brief historical overview of Forest Finnish immigration and ways of life in the area, followed by stops with talks/demonstrations at three locations:
Location 1 Bråtedammen
-
Captures of wild black grouse and capercaillie for research in Finnskogen (Adina Sitje)
-
The hunting management of Statskog (the Norwegian National Forest).
-
From the perspective of the responsible manager (Dr. Jo Inge Breisjøberget/Jonas Hagen)
Location 2 Soppberget capercaillie lek and forestry
-
Capercaillie leks and forestry (Dr. Jørund Rolstad)
-
Norwegian forestry (Dr. Endre Hofstad Hansen)
Location 3 Wind turbine #4 in Kjølberget WPF
-
Scale in research, management and conservation (Dr. Torfinn Jahren)
-
Black grouse and willow ptarmigan populations in the taiga (Prof. Tomas Willebrand)
After the round trip at location 1-3, the buses will leave on a rolling basis, and we will meet for the Forest museum to enjoy a taste of whole-roasted reindeer and capercaillie snacks prepared by our chef and Marius Kjønsberg.
Important infomration
👕 Clothing
Hiking trouser Boots that can handle 3-400 meters in forest terrain (including bog) Weather is unpredictable in September so bring waterproof jakcet/pants
🍽 Meals
The hotel will prepare a luchpack for everyone that we will bring on the buses. You eat this whenever you want. At 14:25 we will also serve grilled reindeer and capercaillie.
⚠ Important to Know
🌦 Program changes may occur due to weather or other unforeseen circumstances
📵 Mobile coverage limited
🌱 Leave no trace: We will follow the Norwegian right to roam principles — respecting nature and leaving no waste behind.
