The sentence that best explains why the native Australian dung beetles were not doing the job is "Cow dung is not part of any native Australian species niche." The beetles in Australia had formed alongside the kangaroos and wombats. When the cattle were brought to Australia in the 1880's by European settlers, the beetles were not used to the texture of the dung. It was much different and the dung was not decomposing. Native beetles were not using this dung as a feeding source. This left the cattle not feeding in the pasture because they won't eat near the dung. This reduced the cattle grazing land.
