Erich Oberdorfer (born 26 March 1905 in Freiburg; died 23 September 2002) was a German biologist specializing in phytosociology and phytogeography. His official botanical author abbreviation is “Oberd."

Life and work[]

Education[]

Oberdorfer studied natural sciences at the University of Freiburg and University of Tübingen after graduating from high school, which he passed in Freiburg in 1923. In Freiburg he heard lectures from Hans Spemann and Friedrich Oltmann, among others . In addition to Felix Rawitscher, Walter Zimmermann, who was assistant to Friedrich Oltmanns at the time, was one of his teachers. He completed his studies in Freiburg in 1928 with a state examination and doctorate. His dissertation, which he wrote under the direction of Friedrich Oltmanns and the ecophysiologist Bruno Huber, dealt with the relationship between the places where different algae grew on the rock faces of the Überlinger See and the light conditions at different depths.

Research[]

Since Oberdorfer initially did not get a job as a teacher because of the economic upheaval, he was entrusted with a research project on the late and post-Ice Age deposits in the Feldmoos on Schluchsee. This work, which was supported by the Notgemeinschaft der Deutschen Wissenschaft, a forerunner organization of the German Research Foundation, was undertaken, among other things, because the Schluchsee was to be dammed up to generate electricity. The field moss should be carefully examined again before it disappears. In this research project, Oberdorfer mainly examined the large remains, which he took from depths of up to seven meters using soil auger, among other things, and established pollen profiles of the different layers. Among other things, he was able to prove in these investigations that in the late glacial of the Black Forest the white silver arum Dryas octopetala and the dwarf birch Betula nana as well as several willow species (Salix herbacea, Salix reticulata or Salix myrtilloides) occurred. With Oberdorfer's research results, evidence for the climatic fluctuations of the Late Ice Age was available for the Black Forest for the first time. With this work, which he continued in addition to his later position as a teacher until 1939, Oberdorfer became one of the pioneers in the field of pollen analysis in Central Europe.

In connection with the investigations at Schluchsee, Oberdorfer dealt with various, then new methods of descriptive vegetation science. He got to know the plant-sociological method according to Josias Braun-Blanquet through Hermann Otto Sleumer and soon had contact with various representatives of this school, such as Braun-Blanquet himself, Reinhold Tüxen and Walo Koch.

Teacher[]

In 1931 Oberdorfer got his first job as a teacher and taught first in Weinheim, then in Bruchsal and Karlsruhe at the grammar school biology and geography. In addition to his work as a teacher, he also mapped the area around Bruchsal using the Braun-Blanquet method. The result was the Bruchsal vegetation map on a scale of 1: 25,000 in 1936. With this, Oberdorfer had created the second vegetation map with this scale. In 1938 the sheet Bühlertal - Hornisgrinde was to appear, as early as 1937 he published a vegetation map of Baden 1: 1,000,000.

Karlsruhe[]

In 1937 Oberdorfer was transferred to Karlsruhe, where he initially got half a deputation as a teacher and a position at the Baden Nature Conservation Agency in Karlsruhe under its director Hermann Schurhammer. In 1938 he left the school teaching service entirely and got a full-time position as a conservator. In doing so, he had to write reports and descriptions of the nature reserves between Lake Constance and the Tauber area, and his trips made him a profound expert on the vegetation of what was then Baden. Work on the plant communities of the Rhine plain, the Black Forest and the Kraichgau later flowed alongside explorations in the Allgäuand in the Alps in his overview of the southern German plant communities, published in the first edition in 1957, in which he also summarized the vegetation recordings of numerous other plant sociologists. The work appeared in a new edition between 1977 and 1992. With this book, Oberdorfer also significantly shaped the plant-sociological nomenclature not only of southern Germany, but of all of Central Europe.

World War II[]

Oberdorfer had experience with the vegetation of Southeastern Europe during the Second World War. He was a botanist at the "Research Season zbV" where the Lieutenant Schulz-Kampfhenkel used and mapped including in Thessaly, Macedonia, Albania, and Thrace, where he made with colleagues phytosociological recordings and auswertete soil profiles.^[1] With studies of the vegetation of northern Spain and a research trip to Chile from 1957 to 1958, he rounded off his knowledge of vegetation outside of Central Europe.

After the war[]

After Oberdorfer was initially only given occasional jobs after the end of the war due to his membership of the SA and the NSDAP, for example as a research assistant to Heinrich Walter at the University of Hohenheim. Starting 1947, Oberdorfer was employed as a curator at the newly established state agency for nature conservation in North Baden (since 1952 District Office for Nature Conservation and Landscape Management, North Baden) and was its director until 1958. In addition to this activity, in 1947 he was also head of the regional collections for natural history in Karlsruhetransfer. However, an official director's position was not created until 1958 and Oberdorfer held this position until his retirement in 1970.

While Oberdorfer's work South German Plant Societies is only known to experts in plant sociology, his plant sociological excursion flora became famous among field botanists. It is the only standard flora in Central Europe that gives detailed ecological information on the species. “Der Oberdorfer” was first published in 1949. In 2001 Oberdorfer published the 8th edition of Flora together with Theo Müller and Angelika Schwabe . With this work, Oberdorfer has made a significant contribution to the shift in field botany from pure floristry to a site-ecological consideration of the vegetation.

From 1950 Oberdorfer held a teaching position for plant-sociological site studies at the Forestry Faculty of the University of Freiburg and was appointed honorary professor there in 1962 .
