Certain animals, known as “ecosystem engineers,” actively shape their environments, creating habitats for other species. Beavers, for example, build dams that transform streams into ponds, benefiting fish, birds, and amphibians. Elephants clear paths through dense vegetation, which creates open areas that support plant diversity and allow smaller animals to access resources. These actions help maintain biodiversity by ensuring that ecosystems remain complex and varied.

These ecosystem engineers contribute to habitat stability and resilience. Protecting such species is essential, as their activities have far-reaching effects on their ecosystems. Conservationists recognize the importance of these animals and often prioritize their protection, knowing that the survival of other species depends on them. By preserving ecosystem engineers, we support biodiversity and the health of entire ecosystems.
