geography

The nature reserve is located on Schönberg above Ehaben in the Breisgau-Hochschwarzwald district .

Characteristics

The area was designated as a nature reserve on November 9, 1937 and is managed by the Freiburg Regional Council under the protection area number 3.003. It has an area of ​​22.6 hectares. The purpose of protection is "the preservation of a rough meadow complex and dry forests with a large number of rare and sometimes endangered animal and plant species in various endangered communities."

history

In 1931 Sumser bought seven contiguous plots of land above Ehaben, which mainly consisted of meadows and trees, discontinued agricultural use on the 7,100 m 2 area and preserved the existing structure with trees, stone walls, dry stone walls and open meadow areas. The following year he had the area entered on the list of official natural monuments. In November 1937 the entry as a nature reserve followed on the basis of the 1935 Reich Nature Conservation Act . From 1948 the care was taken over by volunteers. In 1960 Sumser sold the area to the state of Baden-Württemberg. From 1962 to 1991 the area was completely closed because plants were dug up again and again and the visitors had disrupted the landscape considerably. The site was made accessible again in 1991 and expanded to 22.8 hectares in 1996.

Since 1991 the Sumsergarten has been opened to the public by volunteer nature conservationists during the heyday. However, access for visitors is only possible on weekends and public holidays.

geology

The subsoil comes from the Tertiary . The overlying rocks from the Jura were baked and formed a hard rock called the tertiary conglomerate. Sand-lime brick is added in the Jennetal. The rock weather only poorly, so the soils are shallow and rich in carbonate, which results in the rapid runoff of precipitation and thus the basis for the rough meadows and dry forests.

Flora and fauna

In an expert opinion from 1936 on the establishment of a “Jennetal” nature reserve, Hermann Schurhammer , the then head of the Baden Nature Conservation Office in Karlsruhe, counted 21 orchid species and wrote: “The great scientific value of the properties and the importance they have as a nature reserve lies in their extraordinary wealth of orchids, especially warmth-loving species. ... The area is surpassed in orchid wealth, at least in species wealth, only by the Kaiserstuhl, since Orchis simia and Limodorum are missing. ... The abundance of orchids is the prominent feature of the area and gives it the special value that makes permanent protection necessary but also justifiable. "In a recording from the spring of 1982 Werner Kästle, head of a primary and secondary school in Freiburg, counted 19 species, For example, 480 copies of the Ohnhorn , 64 copies of the Bocks strap tongue and 3 copies of the yellow lady's slipper . The latter has since expired. Approximately 30 species of orchids have currently been identified, and the orchids are now spreading again in the area.

Among the orchids other rare plants like coming Daphne Mezereum , Dioscorea communis , Common Haselwurz , mountain aster and peucedanum cervaria , trees like sessile oak and Speierling , bushes as flour and wild service tree and insects such as the European mantis and at least 33 species of birds.

"In spring, a colorful sea of ​​flowers covers the meadow slopes rich in hedges."

In addition to the many orchid species in the core area, there are many grasslands and bushes in the entire protected area due to the abandoned vineyards. The existing dry stone walls and stone bars of the vineyards offer a good residential area for many rare animal and plant species. For some of the species found here, the area is the northernmost known point of distribution.
