Floralore, bijen, zweefvliegen en zoetwatermosselen
Vroege VogelsBeschrijving van de aflevering
Het gaat slecht met bestuivende insecten in Nederland. Daarom is deze week een grootschalig landelijk onderzoek naar bijen en zweefvliegen van start gegaan. Onderzoekers proberen verdwenen zoetwatermosselen weer terug te brengen in de Nederlandse rivieren. Geertje Jansen is floralorist. Zij verzamelt oude volksgebruiken en verhalen over planten, bomen en struiken. En verder: Milieudefensie en energiecrisis, blauwe reigers in Amsterdamse bos, Usutu-virus bij merels en natuur versus landbouw. De column is van Dolf Jansen. Presentatie: Menno Bentveld.
