Nature reserves in Hong Kong are protected areas established to conserve the region's unique biodiversity and natural habitats. These reserves provide a sanctuary for various species of flora and fauna, many of which are endemic to the area. They also serve as important sites for research and education about the environment. Some notable nature reserves include the Mai Po Nature Reserve, known for its wetlands and migratory birds, and the Tai Po Kau Nature Reserve, which features lush forests and diverse wildlife. These areas offer opportunities for eco-tourism and recreational activities while promoting conservation efforts.
