New research shows that the loss of large animals has had strong effects on ecosystem functions [sciencedaily.com], and that reintroducing large animal faunas may restore biodiverse ecosystems.

Rewilding is gaining a lot of interest as an alternative conservation and land management approach in recent years, but remains controversial. It is increasingly clear that Earth harbored rich faunas of large animals -- such as elephants, wild horses and big cats -- pretty much everywhere, but that these have starkly declined with the spread of humans across the world -- a decline that continues in many areas.

A range of studies now show that these losses have had strong effects on ecosystem functions, and a prominent strain of rewilding, trophic rewilding, focuses on restoring large animal faunas and their top-down food-web effects to promote self-regulating biodiverse ecosystems.
