- Mown meadows with scattered trees were a characteristic of the old Swedish landscape. It has been an established truth that the botanists, particularly R. Sernander and H. Hesselman, did not understand that the meadows would turn into forests when abandoned, whereas the human geographer M. Sjöbeck in several publications from 1927 onwards made this clear. This view was supported by, i.a,. L.-G. Romell. We have scrutinized the literature and the minutes of the Plant Biology Seminar in Uppsala from 1892 to 1944, in order to understand Sernander’s views. Hesselman considered the matter uncertain. Sernander probably understood the dynamics also before 1927, but his standpoint was influenced by a wish to restore the postglacial broadleaved forests of which he saw the meadows as degraded relicts. This could be done by leaving meadows for free development. Gradually he saw the need also to maintain meadows and the cultural landscape as such. Several other botanists, e.g. G. Samuelsson and G. Einar Du Rietz, already early on understood the dependence of meadows on human management.

Var Sellingaffären kulmen på en sekellång botanisk konflikt?

Tidskriftsartikel (refereegranskat)abstract
- The 1950s saw a series of miscarriages of justice against public persons in Sweden. In one of these, the Royal Swedish Academy of Sciences tried to force Olof Selling from his professorship in paleobotany at the Swedish Museum of Natural History, on the basis of mental illness, but this failed after a long and public calamity. In his book Naturen inför rätta [Nature facing trial], Keith Wijkander (2017) claims that Selling was the victimof a century-long conflict between botanists in Uppsala and Stockholm,and places Selling in the Uppsala camp. We try to give a more balanced picture of the relationships between plant ecology in Uppsala and Stockholm during the early 20th century. R. Sernander, L.-G. Romell and G. E. Du Rietz are among the main actors. The fierce debates between the two camps make this an interesting period in Swedish botany.

- Transects covering 90 km inan area south of Linköping in the province of Östergötland, SE Sweden, were relocated and reinventoried in 2013 using the same methodology as in the first national forest inventory of 1927. Data for land-use, forest type and species-specific tree sizes were obtained and compared with values from 1927. The results show that arable fields and pastures have decreased, while forests and areas covered by roads etc. have increased considerably. Picea abies has increased more than Pinus sylvestris. The reasons for the changes are discussed.

- Stinging nettles are not always appreciated, but have been used for spinningyarn and weaving since the Bronze Age, and have also been much used in folk medicine. They are used as food for caterpillars of several of our most beloved butterflies, but area lso victims of an interesting parasitic plant, the dodder.And they can be used to make a delicate soup!
