Census of Sörön

In 1965 a census began of a deciduous forest, called Sörön, it lasted for 40 years with the same person carrying out the census, until 2004. It has since continued, in a somewhat modified form.

Bird ringing is the most time consuming activity at the bird observatory, starting after midsummer and continuing for the remainder of the season until the end of September. When the weather is favourable, ringing takes place every morning from sunrise to noon.

The ringing is standardised which means that the same number of mist nets are used at the same sites year after year. Through this standardisation it is possible to compare different years and analyse changes in the bird populations.

Savi's warbler

In 2012 a project started in which the Savi’s Warbler, a recently established species Kvismaren be studied this has been funded by the Elis Wides fund. The aim is to find out how many individuals are present and how many nests are in the reserve. The secondary aim is to acknowledge if the population is still held up by stray birds or if we have a small yet established population.
