As a human inhabitant of the Wet Tropics World Heritage Area (WTWHA), I am flabbergasted by the Centre for Invasive Species Solution’s 2014 case-study entitled Feral pig management in tropical rainforests of Queensland, which contends that feral pigs do not degrade rainforest dynamics!
The Daintree – Cape Tribulation Section of the WTWHA is the most irreplaceable portion of the second-most irreplaceable WH property in the world and the Southern Cassowary (Casuarius casuarius johnsonii) is the most irreplaceable animal inhabitant. Feral-pigs are federally-declared as a Key Threatening Process. They are invasive and number in tens-of-thousands within the WTWHA and as many as 24-million nationally. For the ecological importance of the Southern Cassowary, tens-of-thousands of invasive feral-pigs have competitively decimated the cassowary carrying capacity. Feral pigs push nesting male cassowaries off their nests and devour their eggs. They also attract pig-hunters, who illegally release pig-dogs (usually four at a time) into WTWHA rainforest. On my 160-acre WTWHA property alone, we have lost over 60 cassowary chicks in the past 6-years and whilst some will have perished through native predation by dingoes & goshawks, the majority would have been killed by pig-dogs and pigs. Feral-pigs also prevent Fan Palms (Licuala ramsayii) from succeeding, robbing the ancient rainforests of the most important contributor to the conversion of tropical cyclones from catastrophic liabilities into tremendous assets. Each pig dredges 12-hours of every day in their relentless search for earthworms and other soil inhabitants. The degradation of the root structure that gives structural integrity to the oldest rainforest in the world is undermined, but all of the disturbed soils are then flushed onto the Great Barrier Reef and between the tip of Cape York and Bundaberg, by an estimated 6-million pigs that reside within the coastal strip off the eastern flank of the Great Dividing Range.
