Australia has become the biological control that is most infamous for having been a complete failure as well as becoming an environmental nightmare. Walter Froggatt, an economic entomologist, warned of this likelihood at the time. It has also led to much public concern and caution when considering the introduction of new biological controls. Another example of a poorly researched introduced biological control is the sap sucking lantana bug (Aconophora compressa) also from South America that was introduced into Australia in the 1995 to eat the lantana. Unfortunately, the lantana bug also attacks other trees including fiddlewood trees which has caused distress to some gardeners. The lantana bug had been tested for six years on 62 different plants. Aconophora compressa was the 28th insect introduced to control lantana in about 80 years. More successfully, the Australian Dung Beetle Project (1965–1985), led by Dr. George Bornemissza of CSIRO's Division of Entomology, introduced 23 species of dung beetle to Australia in order to biologically control the pestilent population of bush flies. These flies, along with other species of fly and parasitic worm, use the dung as a breeding and feeding ground. The rolling and burying activity of the dung beetles means that the dung is removed from the pasture land, which had the effect of reducing the bush fly population by 90%, as well increasing soil fertility and quality by recycling the dung back into the soil. Cooperative Research Centres for weed management and pest animal control, have been established by the federal government. They coordinate research and funding between a number of university and government labs for research into control of invasive species. Non government organisations have also been established to fight invasive species, for example, the Invasive Species Council (ISC). The ISC are a policy, advocacy, lobbying, research, and outreach group on matters related invasive species. Volunteer groups, such as SPRATS, have also made very significant contributions to fighting invasive species, in their case removing sea spurge from large areas of Tasmanian coastline. Claimed ecological benefits While negative impacts by introduced flora and fauna are often featured, some researchers argue that there could be positive aspects of introduced species to provide ecological benefits to native ecosystem in Australia. Herbivores in general may benefit local biodiversity by creating mosaics of vegetation and helping native plants to expand their ranges, and may contribute to decline wildfires; mega-herbivores most notably the camels may fill
