As this chapter has shown, humans are responsible for most of the dangers, disorders and disasters affecting the wombat. Unlike rabbits, sheep, goats and the other introduced animals, which can overgraze the areas in which they live, causing erosion and other problems, wombats tend to live in balance with their environment. When conditions are good, breeding rates increase; but because of their social organisation, wombats do not overcrowd the area they live in - there is still dispersal of surplus animals. Although there may be an increase in the density of wombats in a particular area in a good season, during bad years breeding rates decline and mortality increases. Thus, for tens of thousands of years, wombats have regulated their population. In spite of all that European people have thrown at them, wombats still maintain a dynamic balance with their environment.
