Wolves should be reintroduced in U.S. national parks to help restore damaged ecosystems, according to a new report.
Researchers proposed reintroducing small, managed populations in an effort to improve the biodiversity of many natural areas in North America. These areas have been environmentally impacted by population growth of hoofed mammals, such as elks and deer, which have prospered in the absence of "top-level" natural predators.
More wolves, they argue, would result in fewer hoofed mammals which in turn would lead to greater plant biomass and diversity. A number of recent studies were cited to back up the report's proposal.
