World Heritage: A unique contribution to biodiversity conservation

The 1,157 UNESCO World Heritage sites not only represent the most outstanding places on the planet in terms of human history and culture, but also protect some of the richest areas in terms of biological diversity. The first comprehensive UNESCO and IUCN’s assessment of species that live within these areas, reveals just how critical they are to preserving the diversity of life on Earth.

These extraordinary places, encompassing both natural and cultural treasures, play a vital role in preserving ecosystem integrity and biodiversity. Despite covering less than 1% of the Earth's surface, they harbor over 1/5 of mapped global species richness, making them a haven for an astonishing array of plant and animal life.

Explore the delicate balance between human pressures and conservation efforts, shedding light on the challenges posed by agricultural expansion, infrastructure development, poaching and climate change.
