International Day of Forests seeks to raise awareness about the vital role of forests in preserving our planet's biodiversity and combating climate change. Forests are a main element in global sustainability, sequestering carbon, cleaning our air and water, and providing habitat for countless species. The observance underlines the importance of sustainable forest management, conservation, and the sustainable use of woodland resources.
The UN General Assembly proclaimed the International Day of Forests in 2012. In the UK context, forests hold a pivotal role in the country’s ecological, socio-economic, and cultural aspects. Ancient woodland, a significant element of UK's heritage, makes up only 2% of land area now. The observance emphasizes the need to protect these woods and the biodiversity they support. Woodlands also provide leisure opportunities, enhance mental well-being, and contribute to the economy through timber production and tourism.
In the UK, the International Day of Forests encourages activities including tree planting, educational exhibitions, and forest and woodland walks. Many NGOs, government bodies and communities engage in activities that promote public awareness about the importance and benefits of forests. Schools organise educational activities to instil value for trees and woodland in younger generations. The UK marks the International Day of Forests annually on March 21, aligning with other nations to highlight the world's concern for global forest health.
