Reiseberichte Live lectures Science

On Friday, 26 September 2025, herpetologist Dr Arthur Tiutenko from Friedrich-Alexander University Erlangen-Nuremberg will give a lecture accompanied by numerous images about a very special forest in Ethiopia.

The Harenna Forest, which stretches along the southern slopes of the Bale Mountains in southern Ethiopia, is one of the last remaining forest areas in the Horn of Africa and the largest remaining rainforest on the African mainland. It is not only home to Arabica coffee, but also to numerous other endemic plant and animal species, many of which have not yet been scientifically discovered and described. The herpetofauna of the Harenna Forest includes more than 40 species, including the two large Ethiopian vipers – Bitis harenna and Bitis parviocula. The habitats of these animals and the entire ecosystem are being destroyed by overpopulation and increasing economic exploitation. Even the future of the officially protected parts of the forest looks bleak. This makes it all the more important to gain knowledge about the species that still live in the forest before it is too late. Arthur Tiutenko has explored the Harenna Forest in ten expeditions, the results of which he reports on in this lecture.

Verbreitung Science

Over the last hundred years, humans have reduced Ethiopia’s forest cover from around 40% to just 2.36%. Despite this, little is still known about the country’s herpetological fauna in some places. Scientists from Egypt, the USA and Ethiopia recently carried out a survey study in a national park.

Necisar National Park is located in south-west Ethiopia on the line of the Great Rift Valley, more than 500 kilometres south of the capital Addis Ababa. Necisar covers an area of 514 square kilometres, bordered to the north and south by two lakes, to the east by the Amarao Mountains and to the west by the town of Arbaminch. Nechisar is very hot all year round with very little rainfall.

A total of two expeditions were carried out during the rainy season and two during the dry season. Transects with a total length of 290 km and a width of nine metres were covered, 230 km of which were in grassland and stony terrain, 60 km in the forest and along the lakeshore. In addition to manual searches with the naked eye, small pitfall traps and cover plates were used.

A total of 34 species of reptiles were found, including Chamaeleo gracilis. The species was discovered twice. Both chameleons were found near different rivers, one in the scrubland and one in the forest.
