For this reason, biological warfare against rabbits in Australia is a serious concern for conservation activities in other parts of the world. Their ability to breed enables them to rapidly build up numbers after a drought or the release of a new bio-control. What happened several years after the rabbit was introduced into Australia? Frank Tidswell, who was his chief Australian collaborator, continued Danysz's trials after he left in 1907, and also began trials of the Yalgogrin, Gundagai, and Picton microbes (named for the stations where infected rabbits were found), but financial support was lacking from the Federal government, or the collaboration of affected states, that would be necessary to prove that the measure safe and effective.
