International Day for the Conservation of the Mangrove Ecosystem 2026

The International Day for the Conservation of the Mangrove Ecosystem is observed on July 26, 2026. It was proclaimed by the United Nations Educational, Scientific and Cultural Organization (UNESCO) in 2015 and has been marked annually since then. The date does not commemorate a specific historical event.

Mangroves are coastal trees and shrubs that grow in saline or brackish water, forming dense forests along tropical and subtropical shorelines. Their complex root systems stabilize coastlines, reduce erosion and provide critical habitat for fish, birds and other wildlife. The purpose of the day is to raise awareness of the ecological importance of mangrove ecosystems, which provide coastal protection, support biodiversity and serve as carbon sinks.

The International Day for the Conservation of the Mangrove Ecosystem promotes conservation, restoration and sustainable management. UNESCO encourages research, education and international cooperation to protect mangrove habitats from degradation and loss.
