International Day for Biosphere Reserves

Nov. 3, 2025

A Biosphere Reserve is a territory recognised by UNESCO in which a balance is promoted among nature conservation, sustainable development and the well-being of local communities.

To mark this occasion, here are some interesting facts:

Did you know that...

...globally, there are 785 Biosphere Reserves in 142 countries, forming a living network that promotes sustainability, biological and cultural diversity, and the exchange of knowledge between communities.

...in the Flores Island Biosphere Reserve, known as ‘the westernmost territory of Europe’, there are some of the largest waterfalls and lakes in the Azores, making this territory a true natural sanctuary of water and biodiversity.

...the Corvo Island Biosphere Reserve was a pioneer in launching the SOS Cagarro Campaign (although it was recognised and made official in 1995, brigades had already been formed in 1991 to rescue these birds on Corvo), and since 2020, all public lighting on the island has been turned off during the most critical period of the campaign?

...around 25% of the Cory’s Shearwater rescues carried out during the SOS Cagarro Campaign take place in the Fajãs de São Jorge Biosphere Reserve, where nature and the local community work together to preserve marine life.

...the 6th edition of the newsletter ‘Graciosa - Biosphere Reserve’ is being launched today? Access the full newsletter at https://bit.ly/3LqsGT7 and stay up to date with the latest news.
