They also secrete toxins capable of killing just about any animal they come in contact with (humans have died after ingesting their eggs), meaning that they tend to be seriously lacking in the natural predator department.

MIKE CHUK: The declaration is important because without declaration, you don't have that degree of effort and emphasis by the community to do something about it and you don't have the pressure on politicians to perhaps fund efforts to reduce the spread of buffel grass. ROD CRAMER: We've got this super weed which is not as palatable as the desirable ones and eventually that's all we're going to have.KERRY STAIGHT: Back in the early days when native grasses weren't highly rated, the CSIRO brought in different strains of buffel from all over the world and planted them in trials at Alice Springs

Dog and Cat Vaccinations in Australia: How Much? How Often?
Spaniels in particular are prone to autoimmune diseases and breeders say that yearly vaccinations can increase their chances of getting an autoimmune disease. Vaccinations for the above diseases last for three years according to the experts, but here in Australia vets still recommend this vaccine on an annual basis
Unfortunately, as we have disturbed traditional wetland areas, either through spreading urbanisation or agricultural use, we have destroyed the habitat of this graceful bird. Unfortunately, releases of Rufous Hare Wallabies into the park were unsuccessful because they were wiped out by feral cats, which were then still a problem
Fifty Orwell Essays
The immediately striking thing about all these papers is their generally negative, querulous attitude, their complete lack at all times of any constructive suggestion. (Actually it is a few miles from Bray, but perhaps at that time the two livings were one.) In the churchyard there stands a magnificent yew tree which, according to a notice at its foot, was planted by no less a person than the Vicar of Bray himself
80 Facts to Mark 80 Years of Cane Toads
Queensland Museum arachnid expert Dr Rob Raven says there are several native spiders, including Queensland's native tarantula, that are known to kill and at least partially eat cane toads. Dr Greg Brown, part of a University of Sydney research team called Team Bufo based at Fogg Dam in the NT, has used radio-tracking to follow individual toads in the vanguard of the invasion front
Cane toads turn out to be their own worst enemy
See, scientific research is terrific! Commenter Kate Date and time Wed Jun 13 02:45:20 UTC 2012 sounds good,lets hope it works! Commenter iany Date and time Wed Jun 13 02:59:29 UTC 2012 As bad to the ecosystem as they are, if we actually managed to get rid of the little bastards I think I'd actually miss them (a little). Commenter Cynical Observer Location Sydney Date and time Wed Jun 13 03:17:03 UTC 2012 Thankfully some really good news on the invasive species front, particularly as the cane toad has done massive damage to our native biodiversity

Some other animals, such as feral camels, are also the subject of national plans for management as Existing Pest Animal of National Significance, (under the Australian Pest Animal Strategy) Threat abatement plans Competition and land degradation by unmanaged goats Competition and land degradation by feral rabbits Predation by feral cats Predation by the European red fox (Vulpes vulpes) Predation, competition and lethal toxic ingestion caused by cane toads (Bufo marinus) as a key threatening process under the EPBC Act (public comments on draft TAP closed) Predation, habitat degradation, competition and disease transmission by feral pigs Reduce the impacts of exotic rodents on biodiversity on Australian offshore islands of less than 100 000 hectares National action plan National Feral Camel Action Plan Impacts Australia's native plants and animals adapted to life on an isolated continent over millions of years. Fencing for wildlife management has a long history in Australia with the introduction of netting fences for rabbit and dingo exclusion over 100 years ago
Best way to kill cane toads is in the freezer, says Australian study - Telegraph
"So if you don't want an unpleasant surprise when you pull out your bag of frozen toads, leave them in there a bit longer." Australia has long grappled with the problem of controlling its fast-growing cane toad population, which is believed to exceed 200 million and poses a significant environmental threat. The discovery was made by researchers who implanted pain-sensing electrodes in the brains of toads and then put the creatures into a refrigerator for several hours before transferring them to a household freezer
It turns out that most of these toads have hitched a ride with building and landscaping materials - and that the numbers of adult toads reaching Sydney are very high. How can they do it? Sam McCann showed that toads in high cold sites select open areas where they can stay warm by basking, and that their physiology shifts rapidly when they are exposed to cold
The biological effects, including lethal toxic ingestion, caused by Cane Toads (Bufo marinus)
The lethal dose of toad toxins was assessed for ten of these species with 7 of the 10 being identified as easily capable of ingesting a fatal dose of toxin in a single meal. Cane Toad tadpoles appear to significantly affect tadpoles of the ornate burrowing frog, Limnodynastes ornatus, probably as a result of the superior competitive ability of Cane Toad tadpoles, rather than predation of early life stages of the species (Crossland 1997)
Evolutionary And Ecological Processes Of The Invasive Cane Toad Biology Essay
While it is presumed that the difference in dispersal rates will be dependent on the surrounding vegetation of these roads, there is no empirical evidence to support such claims. More empirical tests are needed in this area of study, not just on cane toads but on other species that have advancing populations, to help us better understand the potential importance of the spatial selection process
Cane Toads - National Geographic Education
Human beings are the most powerful and effective predator of cane toads in Australia! In the cane toad's native habitat of Central and South America, it has many natural predators.
