We bid farewell to a devoted environmentalist and friend, Yiannis Roussopoulos.
Yiannis Roussopoulos
Our supporter and friend of ARCHELON, Yiannis Roussopoulos, has passed away. A devoted environmentalist, he was involved in many aspects of Greek nature, focusing mainly on birds. He developed extensive expertise in the identification and assessment of habitat types and, more broadly, in landscape ecology. At the same time, he passionately photographed birds and habitats and authored several books on these subjects. His photographs and articles were featured in newspapers such as Eleftherotypia, Kathimerini, and in the magazine Gaiorama. He also worked with sea turtles in several of our projects, mainly in Mesolongi and the Amvrakikos Gulf, areas he knew very well.
His loss leaves a void in the environmental community and brings deep sorrow to all who knew and worked with him.
