The primary purpose of protected areas in biodiversity conservation is to preserve natural habitats and the species that inhabit them. These designated regions serve as refuges from human activities, allowing ecosystems to function unimpeded. Protected areas are vital for maintaining biodiversity, preventing habitat loss, and supporting ecosystems that provide essential services such as clean air and water. They also facilitate research and educate the public about conservation. By safeguarding critical habitats, protected areas contribute significantly to global efforts aimed at mitigating the impacts of climate change and enhancing overall ecological resilience.
