11.4 In situ conservation and protected areas

In situ conservation focuses on protecting species and ecosystems in their natural habitats. This approach preserves genetic diversity, maintains ecosystem functions, and allows species to adapt to changing environments over time. It's a crucial strategy for long-term biodiversity preservation.

Protected areas are designated regions managed to conserve biodiversity and natural resources. They vary in size and protection levels, from strict nature reserves to sustainable use areas. These spaces provide habitats for threatened species, maintain ecological processes, and offer educational opportunities.
