Habitat fragmentation is significant in biodiversity because it leads to the division of ecosystems into smaller, isolated patches, affecting species survival. This process can disrupt species migration and reduce genetic diversity, making populations more vulnerable to extinction. Fragmented habitats often result in edge effects, altering environmental conditions and increasing exposure to predators and invasive species. Understanding habitat fragmentation allows for informed conservation strategies, including the creation of wildlife corridors and restoration of natural habitats to support diverse and resilient ecosystems.
