Röbäcksdalen research station is a bit different from the other SITES stations. It is a managed ecosystem that produces biomass, which feeds the animals on the station’s farm. The farm has a crop rotation that is typical for northern Sweden, with leys of grass and clover, barley, pasture, and some additional pea/oat mixtures and fallow fields. The annual output from this ecosystem varies with many things including; winter survival of perennial crops, temperature and rainfall during the vegetation season, and much more.

On a global scale, forests currently act as a sink for atmospheric CO2. Forest management plays a large role in determining the CO2 uptake and long-term carbon storage in forests. Managed forests usually have lower ecosystem carbon stocks compared to pristine or old-growth forests, hence there is great potential to increase active terrestrial carbon sequestration if forests are managed appropriately. There is an ongoing debate over which forest management system provides the greatest long-term climate benefits.

In midwinter, when fewer field surveys are running, SITES´ data collection continues indoors. One project is to go through tick (Ixodes) material from last summer and the physical samples from marked animals.After collection in the field, samples are stored in Cryo freezers (-80°C), until they can be analyzed. Tick occurrence and frequency in different habitats are estimated using a specific survey method (“flagging”), but ticks are also collected from wild animals that are handled, e.g. voles (Microtus spp.) and roe deer (Capreolus capreolus). 

The SITES Secretariat wishes our community, friends and associates a good start in the New Year. We hope that despite the ongoing pandemic a way back to a normal life with regular activities like in-person meetings, workshops and travel will be possible this year. There are many exciting things to look forward to in 2022, not least the transition into a new funding phase.
We wish you endurance for the probably still tough weeks ahead and stay healthy!

As we near the end of the year, we wanted to thank you for your continued commitment and perseverance through 2021! There are many things to be thankful for this year including reconnecting in person with the SITES community and continued funding for years to come. We look forward to keeping the monument and continued journey with you in 2022! God Jul! Enjoy the holidays and best wishes for 2022 from the SITES Secretariat! 

At Svartberget Research Station, an ongoing soil project, investigating soil organic carbon and nitrogen, uses plastic balls added to the soil pit to estimate pit volume.  

The onset of ice at Lake Erken occurred on Dec 6th this year, which is a record in recent years, but put in the historical context not so unusual.

A project focusing on intercropping of faba beans and peas has been initiated at SITES Lönnstorp Research Station. This year was the first of the three-year project period.

In late autumn, work at SITES station Grimsö mainly comprises of digitalization and compilation of data from the earlier peak season, and lab work to specify ticks sampled from voles etc. However, outdoor activities still run in autumn, one of which is the hazel grouse survey.

As part of the work to prevent and monitor forest damage, the government has invested money in a National Center for Forest Damage. The Center is a collaboration program, where SLU’s Skogsskadecentrum (Forest Damage Center) has participated in several projects in collaboration with other actors.
