1st International Bat Research Online Symposium (IBROS):
Towards solving the wind energy-bat conflict

The global expansion of wind energy production represents an, as yet, unsolved green-green dilemma due to habitat degradation caused by the erection of turbines and the risk for bats of colliding with the rotating blades. Effective compensation and mitigation schemes are central for making so-called green energy production by wind turbines ecologically sustainable. We have invited a number of keynote speakers who will report on the wind energy-bat conflict from their country or continent, and present new scientific evidence on how to protect bats efficiently at wind turbines.

The online symposium is aimed at scientists, representatives of authorities, experts and representatives of wind energy companies. The event will be conducted in English.


Tuesday, 2nd November 2021
08:45 - 17:30 (CET)

Event format & technical details

The online symposum will be delivered remotely with live lectures in Central European Time.

We will be using the video conferencing tool 'Webex meetings'. Technical requirement for participation is a stable internet connection.

We highly suggest using a laptop/PC instead of a smart device to best follow along.  During the symposium, you will have the opportunity to ask questions and participate in the live discussion. For good audio transmission, we recommend the use of a headset to avoid background noise. If you do not have a microphone/headset, you may as well ask questions via the chat option.

Registered participants will receive the access link to the symposium a few days prior to the event.

In addition, the lectures will be recorded and will be available for all attendees for three days afterwards.


If you would like to participate in the symposium, please register at:

Regular registration fee: 60 Euro
Reduced registration fee: 40 Euro*

*The reduced rate applies to participants resident in and affiliated with organisations of non-high-income countries (see World Bank classification) and for students and NGO employees of any country. For verification, please send us an appropriate proof by email to batsymposium@izw-berlin.de.

Registration is open until 31st October 2021 midnight CET.
