Humans might be the ultimate ecosystem engineers in the sense that we constantly modify ecosystems and change the processes which drive them. In some cases, this can harm biodiversity by displacing native ecosystem engineers which deliver important benefits for other species and bolster both habitat and species diversity (Romero et al. 2015). Humans also can leverage their ecosystem engineering to benefit biodiversity, such as through mimicking ecosystem engineering structures as part of restoration. Our recent paper (Goss et al. 2025) reviews how mimicked ecosystem engineer structures might help meet restoration goals, and potential risks with the use of these human-engineered structures.
