Ancient woodland refers to forests that have existed for at least 400 years, characterized by a rich biodiversity and complex ecosystems. These woodlands often contain a variety of native trees, plants, and wildlife, making them important for conservation efforts. They are typically home to species that rely on stable habitats, which have developed over centuries. In many countries, ancient woodlands are protected due to their ecological significance and historical value. They provide essential services, such as carbon storage and water regulation, and are often linked to cultural heritage. Preserving these areas is crucial for maintaining biodiversity and combating climate change.
