MACQUARIE MARSHES, NSW, AUSTRALIA - OCTOBER 07: Ancient River Red Gum trees and small patches of dried out reeds stand dead from a lack of water October 7, 2007 in the Macquarie Marshes in New South Wales. Environmentalists and farmers have battled over the water in the marshes, with growers feeling they need the resource to produce food and the other side fighting for habitat for birds and other wildlife. Southeast Australia has been plagued with severe drought since the late 1990's and many growers and policy makers are being forced to work on implementing more efficient irrigation systems.
