For the third time, ABOL was able to participate at the Day of Biodiversity in the Biosphere Reserve Wienerwald with a BioBlitz action. Around 70 biodiversity experts explored the Eichgraben municipal area on June 18th and 19th, 2021 in order to record as much fauna, flora and funga species as possible. Although the conditions were not ideal for some groups of animals and plants – many meadows had been mowed shortly before and there was high temperature and drought – more than 1,300 species could be detected this year. DNA barcodes will be generated from some of them after they have been identified and processed by the experts in the course of the ABOL BioBlitz campaign.

The first nature enthusiasts arrived on Friday morning in search of species – the last ones set up their light traps on Friday night to attract and detect various nocturnal insects. On Saturday morning, experts poured out into the municipality again and tried to compile a list of species as comprehensive as possible by early afternoon. The old nursery in the village of Eichgraben served as a base, where the Biosphere Reserve team took care of the well-being of the participants and provided lunch packages and cold drinks. Unfortunately, due to the Corona-regulations, no public event like in the years before the pandemic could take place this year. For those interested, however, there was the opportunity to take part in various nature excursions.

We would like to thank the Biosphere Reserve team for the excellent organization and all those who participated in the ABOL BioBlitz!

Dear ABOL Community

We would like to continue the tradition of annual ABOL conferences. The 8th ABOL meeting will take place on Tuesday, November 30th, 2021 following the Forum on Biodiversity and Ecosystem Services at the Danube University Krems. The two events will again be organized together as Days of Biodiversity. We hope that face-to-face events are possible, but if necessary we will hold them ONLINE.

We will keep you informed and ask you to save the date!

*** It is planned to hold the Days of Biodiversity 2021 as a Green Meeting. ***

Best regards,

the ABOL coordination team

 

The first ABOL BioBlitz 2021 took place on June 11th and 12th, at the Danube Island (Donauinsel) during the 20th Vienna Day of Biodiversity organized by the departments of the municipality of Vienna for environmental protection and water. Numerous biodiversity experts swarmed out to record the fauna, flora and funga of the Donauinsel, especially in the area of ​​Wehr 1 and Tritonwasser, whereby samples were also collected for the creation of DNA barcodes.

Experts met on Friday evening to attract moths and other nocturnal insects with numerous light traps. On Saturday, when the weather was mostly fine, the well-developed, species-rich meadows around the basecamp were investigated. Not only the honey bee was strongly represented on the numerous flowering Knautia individuals but also the solitary bee Andrena hattorfiana, which is an oligolectic species feeding on Knautia pollen and a few other Dipsacaceae. Even the parasite of A. hattorfiana, Nomada armata, could be detected. Numerous other insect species were found in the meadows. The nearby Triton water with beautiful silting zones in which water frogs could be found in large numbers was particularly interesting for the amphibia experts. It is particularly gratifying that – although the data reporting has not yet been completed – with Trigoniophthalmus alternatus, a representative of the large group of bristletails, a new record for Vienna has already been booked.
Unfortunately, due to the corona pandemic, no public event could take place this year, but it should be rescheduled at the same place next year.
We would like to thank the organizers and the participants of the ABOL BioBlitz!
