You will be surprised to know, that there have been many reports of koalas being given birth control for the sole purpose of fighting their overpopulation. This is taking place in most parts of Australia, this practice of Koalas’ sterilization has taken everyone by the storm. The fact that it is actually working has come as a relief for the scientists and zoologists. A famous expert in the field, David Ramsey who belongs to the Arthur Rylah Institute for Environmental Research situated in Melbourne Australia, along with his many colleagues, have gotten the chance to run a successful analysis of the effect of fertility control programmes on the population of koalas in different areas, where the animals have been able to breed very successfully, further leading to the risk of starvation. The researcher also played a key role in studying a programme which was invented during 2004 to 2015 in the Budj Bim National Park, located in Victoria, as per this study the female koalas were not just captured but also treated with an implant of levonorgestrel.
