Habitat fragmentation occurs when large, continuous habitats are divided into smaller, isolated patches. This can happen due to human activities like urban development, agriculture, and road construction. As a result, wildlife populations may become separated, making it difficult for animals to find mates, food, and shelter. Fragmented habitats can lead to a decline in biodiversity, as some species may struggle to survive in smaller areas. Additionally, the edges of these patches are often more vulnerable to environmental changes, such as climate change and invasive species, which can further threaten the health of ecosystems.
