Danish biologists have come up with an unusal way of maintaining a local nature reserve - instead of machines they're using elephants.
Three elephants from a local circus - Laksme, Teach and Kenya - joined the gardeners at Vesterlyng nature reserve as part of an experiment to try to find out whether elephants could partly substitute machinery and tend the area in an environmentally friendly way. Unlike machinery, elephants can tear out small trees and bushes without leaving big gaping holes, not to mention the pollution the machines cause.
