How does forest fragmentation pose risks to wildlife?

Forest fragmentation presents significant risks to wildlife primarily by isolating animal populations. When forests are fragmented, they can be divided into smaller, more isolated patches. This fragmentation can limit the movement of animals between different habitat areas, making it difficult for populations to access resources such as food and mates.

Isolated populations are more vulnerable to genetic problems due to inbreeding, which can lead to decreased genetic diversity and resilience over time. Animals might also face increased predation and competition as they are pushed into smaller areas, and they might not be able to migrate or adapt to environmental changes effectively.

In this context, the fragmentation reduces the overall effectiveness of ecosystems as functioning habitats by making it possible only for certain species to survive in smaller patches. This can lead to declines in biodiversity and the potential local extinction of species that require larger territories for their survival.
