Ortolan bunting
This species have been surveyed at irregular intervals since 1968. Nowadays, they’re almost extinct in southern Sweden as a breeder and there are only 10 or so singing males in Kvismaren. In the beginning of 2010 we started a project to determine how they are to be preserved as a breeding species. In Kvismaren work is ongoing to verifying the nesting outcome when active measures are taken by land owners and land left fallow by the edges of fields. In the spring these areas are not planted and therefore presumably protecting the breeding habitat of the Ortolan’s.

Started in 1968 rather tentatively, a study of the moulting adult birds caught in Kvismaren began; this is when birds are replacing feathers completely after nesting. As of 1973, almost all the specimens caught in this category are investigated according to their moult. This take place on a special form; a schematic diagram of the wing and tail.
To date, over 10 000 moult cards have been completed.
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.
