The Victorian bush fire hit most of Victoria's bushland, but it is the environment that was hit the hardest. As one of the worst burn-offs that Australia has seen, it has obviously had a great affect on the wildlife. The Royal Society for the Prevention of Cruelty to Animals has estimated that wildlife injury and death would tally more than a million. Many of the surviving wildlife suffered burns and other injuries. A species of possum, the Leadbeater's Possum, had its only known habitat burned, putting it under extreme threat of extinction. Of course, the plants in the bush were most affected, and this has had, and will have, impact on the prospects of the many animals who need the vegetation for survival (like koalas and possums), who have all lost vast areas of habitat. Also, regrowth in the burned areas will affect run-off rates, availability of water, and infrastructure, such as dams, and dam maintenance for decades. The greater environment has not gone unscathed either with evidence of smoke from the fires, found high over Antarctica.
