1. Since 1997 the Bat Night is organised under the auspices of the Agreement on the Conservation of Populations of European Bats (EUROBATS). The Bat Night has taken place every year in more than 30 countries on the last full weekend of August. Nature conservation agencies and NGOs from across Europe pass on information to the public about the way bats live and their needs with presentations, exhibitions and bat walks, often offering the opportunity to listen to bat sounds with the support of ultrasound technology.

  2. The first International Day for the Conservation of the Mangrove Ecosystem was celebrated on 26 July 2016, to mark the critical importance of mangroves for food security, coastal protection, and mitigation of the impacts of climate change. The proclamation of the International Day for the Conservation of the Mangrove Ecosystem – which was adopted in November 2015 by the General Conference of UNESCO – underlined the importance of the mangrove ecosystem as a “a unique, special and vulnerable ecosystem, providing by virtue of their existence, biomass and productivity substantial benefits to human beings, providing forestry, fishery goods and services as well as contributing to the protection of the coastline and being particularly relevant in terms of mitigation of the effects of climate change and food security for local communities.”

  3. The World Fish Migration Day (WFMD) is a one day global celebration to create awareness on the importance of open rivers and migratory fish. On World Fish Migration Day organizations from around the world organize their own event around the common theme of: CONNECTING FISH, RIVERS AND PEOPLE. WFMD is celebrated every second year on the 3rd Saturday in May.
