Highlighting the devastation due to invasive species and the imperative of investment in their control remains as relevant as ever according to several recent articles – especially given the impact of alien species on native species, ecosystem services, human health, and food production. A study published in ‘Frontiers in Ecology and the Environment’ found that […]
A tiny Alaskan island faces a threat as deadly as an oil spill – rats. However, ‘biological spills’ can be much worse than oil spills, because they don’t necessarily diminish over time. Biological pollution can adapt, self-propagate and spread, says Professor Anthony Ricciardi from McGill University, Montreal. Interesting to think of invasive species, like wild […]
The national Bilby Recovery Plan is under review, and new research may help re-introductions in southern Australia. The Bilby was adopted as a mascot by RFA to highlight the impact of rabbits on native wildlife and vegetation. According to the draft Recovery Plan for the Greater Bilby; ‘Bilby distribution is associated with an absence or […]
Victoria’s Rabbit Action Network has gained international acclaim with a United Nations Public Service award, for ‘delivering more inclusive and equitable services’. The program, delivered by Agriculture Victoria, brings together whole communities – land managers, farmers, scientists, government officials and the wider community – to manage one of their most invasive species, the European wild […]
A mix of recent stories from New Zealand highlight the importance of controlling invasive species for the benefit of native plants and animals – and the importance of public engagement as part of the solution. An article in the NZ Herald begins by asking if there is any solution to the devastating problem of rabbits. […]
Several recent news stories highlight the importance of controlling feral animals, like rabbits, cats and foxes, in order to restore native ecosystems. Scientists have shown that invasive species are responsible for hundreds of species becoming extinct, and have concluded that removing invasive species from islands would benefit nearly 10% of the most endangered species on […]
‘If overabundant wildlife populations are not reduced by some means, the result must be death by starvation or disease coupled with extensive damage to other species in these ecosystems,’ say ecologists Charley Krebs and Judy Myers. The killing of animals is abhorrent to many people, but alternative controls (e.g. capture and relocation or sterilisation) or […]
Successive biological controls for rabbits have been the most important factor in the recovery of sand dunes along the Coorong in South Australia. Researchers from Flinders University have recorded peaks in vegetation regrowth and dune stabilisation coinciding with various biological controls, ranging from myxomatosis (1952) and the rabbit flea (1968), to RHDV (in 1995 and […]
Rabbits negatively impact more threatened species in Australia than does any other invasive species, according to the Threatened Species Recovery Hub. Over 300 threatened native species are at increased risk due to rabbits – more than from any other invasive species. For more information, see the report by Kearney et.al (2018) in Pacific Conservation Biology […]
Calls for ‘compassionate conservation’ (the protection of individual wild animals, regardless of whether they are native or an introduced invasive species) may be rebuffed by ecologists, citing any number of examples of the environmental harm caused by invasive species and the environmental benefits that come from their control or eradication. However, several social issues are […]
