We held our first ever DarkDivNet conference on 20-23 November with ~70 participants from all over the world. Two days were filled with interesting plenary and ordinary talks as well as poster presentations covering the dark and hidden diversity of plants and fungi. Several current or previous members of our workgroup also presented their recent findings. On the last day of the conference we explored some of our DarkDivNet sites in southern Estonia and visited the Tartu observatory.
