Protect Habitat to Save Wildlife from Extermination
Australia urgently needs more research on protecting the habitat of
our unique wildlife “if we are not to be mute witnesses to their rapid
extermination in the next 20–50 years,” according to an expert on how
Australian animals adapt physiologically to their particular
Emeritus Professor Don Bradshaw, who held the Chair in Zoology at the
University of Western Australia for 28 years, issued his call in the
November/December edition of Australasian Science, published today.
Among the animals Prof Bradshaw has studied is the spectacled hare
wallaby, one of the many rare and threatened species found on Barrow
Island, the site of the recently announced Gorgon gas project.
Prof Bradshaw says that while “the need to protect and preserve
Australia’s unique and diverse flora was recognised early by
legislation passed in the various states… the case was not so simple
with fauna, many species of which were regarded as vermin and others
hunted for their skins.”
Prof Bradshaw point out: “Animals also move and, while it is easy to
protect the place where a plant grows, defining an animal’s habitat is
more difficult and depends on detailed research”.
Prof Bradshaw says that the Wildlife Conservation Act in Western
Australia “does not bind the Crown” to protect the habitat of
threatened fauna. While a move was made in 1991 to address this, there
is still no legislation in place 18 years later. This means that
“while it is an offence to take or kill a rare animal it is not an
automatic offence under Western Australian law to destroy its unique
Nationally, the Environmental Protection and Biodiversity Conservation
Act 1999 lists a number of threatened and endangered species and
offers protection to these and their habitat. But, this only applies
to those species listed in the Act, and only 91 of the 250-odd species
of mammals in Australia are listed.
Prof Bradshaw identifies many threatening processes that lead to
habitat destruction and the eventual loss of biodiversity, including
“clearing for development, introducing exotic competitors like sheep,
rabbits and weeds, salinity, plant pathogens like Phytophthora
cinnamomi and fire. The effects of fire on habitat are perhaps the
least well-understood, and debate rages over the benefits and perils
of prescribed burning, especially following the devastation of this
year’s Victorian bushfires.”
