What does "habitat fragmentation" refer to in wildlife management?

Habitat fragmentation refers specifically to the disruption of habitats into smaller, isolated patches. This phenomenon typically occurs due to human activities such as urban development, agriculture, and transportation infrastructure, which divide once continuous ecosystems into smaller fragments.

The significant consequence of habitat fragmentation is that it often leads to a decrease in biodiversity. Isolated patches may not support the same variety of species as larger, connected habitats, as they can limit the movement of wildlife, hinder access to resources, and reduce gene flow between populations.

In contrast, the other options describe different ecological concepts and practices, such as the creation of new habitats, ecosystem restoration, and the increase of biodiversity—all of which do not align with the definition of habitat fragmentation. Thus, the correct understanding of habitat fragmentation is crucial in wildlife management and conservation efforts to ensure the preservation of species and ecosystems.
