The biannual ECSA conference organised under the theme Citizen Science for Planetary Health got off to a great start in Berlin on 5 October with a welcome reception in the Museum of Natural History. The surroundings, dominated by dinosaurs and other fossils was a fine reminder of the importance of protecting the environment, the theme that runs through so many Citizen Science projects. The agenda over the following two days was intense with presentation and discussion sessions involving the almost 500 participants in debate about the best ways to organise Citizen Science activities to have the most impact. The CS Track project was very much in evidence and the team provided three different presentation inputs – all of which were really well attended. We also contributed 5 poster inputs to the surprisingly well-attended and engaging poster sessions on Friday. Then on Saturday 8 October we organised the CS Track Symposium in the Museum of Natural History as part of the ECSA conference programme. Over 70 people took part in this half-day symposium made up of talks, workshops and discussions providing valuable input and feedback to so many of the project’s outputs which are now coming to fruition.
