Parallel to the Day of Biodiversity (Tag der Artenvielfalt) in the National Park Hohe Tauern, the 5th GEO Nature Day was held in the Biosphere Reserve Nockberge on 17th & 18th June. Similar to the previous year, ABOL participated with the BioBlitz campaign to demonstrate the opportunities of DNA-barcoding to the taxonomic experts, and also to actively participate in collecting. Over 60 experts tried to find as many species as possible around the Grundalm within 24 hours. Some of the experts were also accompanied by their children, which not only increased the family atmosphere of the event, but also raised the number of collecting people.
Due to the sensational number of participants, the targeted species number was quickly set – more participants than last year should result in more species detected, therefore the goal was more than 2,000 species! It was clear to everyone that this not entirely serious goal would be difficult to achieve, due to the high altitude of the study area (1600 and 2300 m above sea level). The rainy weather also dampened theses overly ambitious expectations. In the end, not a single dragonfly could be found, despite the intensive search by several odonatologists. Light traps set up at night also failed to meet expectations due to the weather. Under normal conditions, dozens of insect species with hundreds of individuals would be recorded. This year, only a handful of arthropods were detected with the light traps. Nevertheless, with about 850 species a sensational result was achieved and the number will even increase due to re-determinations and the analysis of e.g. sediment samples. It is especially nice that many species typical for these altitudes could be found, such as the brown discus snail (Discus ruderatus), the Alpine marmot (Marmota marmota) or the Alpine salamander (Salamandra atra). Fortunately, several species relevant for the BioBlitz campaign were collected too, for which DNA barcodes will soon be created and made available on BOLD.
The excellent organization of the event should also be mentioned. From accommodation to the offer of a shuttle service to the study area, to a great catering including an excellent cake buffet from local farmers and the distribution of Biosphere Reserve Nockberge tube scarves, everything was perfect. The latter were in times of Corona very useful as mouth and nose protection, but also as headgear at temperatures below 10°C. The final commitment of the organizers for further GEO Biodiversity Days can only be topped with the appropriate hours of sunshine…
