Which of the following describes natural corridors?

Natural corridors are essential features in landscape ecology that help maintain wildlife populations and biodiversity. They refer to paths or strips of habitat that connect various patches of natural environments, allowing animals to move between these areas safely. This connectivity is crucial for wildlife, as it enables them to find food, mates, and suitable habitats, reducing isolation of populations and enhancing genetic diversity.

By providing a safe route for animals to travel, natural corridors help mitigate the effects of habitat fragmentation caused by urban development and agriculture. This connectivity is vital for species that require large territories or specific habitats to thrive.

The other options do not capture the essence of what natural corridors represent in ecological terms. Areas devoid of vegetation do not support wildlife movement, paved roads facilitate human transit but hinder wildlife connection, and underground tunnels for pest control serve a specific function unrelated to the ecological connectivity that natural corridors provide.
