The truth: gardens are healthy

Environment

The great Australian backyard is under threat - and that could spell disaster for our children and our health.

University of Adelaide biodiversity expert Professor Chris Daniels says the lack of gardens in new housing developments is a worrying urban trend.

"People are raising families in very sterile and antiseptic environments and our kids are at risk of growing up without environmental values," he says.

Professor Daniels, from the School of Earth & Environmental Sciences, says planners are forgetting the big picture in urban areas.

"Most new housing developments have very little garden area. This presents two problems: it limits the number of birds and plants that inhabit the environment; and it removes an incentive for families to exercise.

Professor Daniels says raising children in a concrete environment might well stunt their environmental creativity and inquisitiveness. " It is certainly not healthy."

"There are good reasons for building low maintenance communities for the elderly, but not for younger communities."

The biodiversity academic attributes the loss of large numbers of flora and fauna in Adelaide's inner city areas to extensive clearing for housing developments.

"The more we simplify our environment, the less species will be able to inhabit it."

Professor Daniels cited the parklands as an example: "If you walk through the parklands you will only see about eight or ten species of birds. Yet if you cross the roads to the garden suburbs of Parkside or Rose Park you will see about four times the number of species. That's because these suburbs have gardens, more flowers and a much more complex environment."

Sections of the parklands could be developed to suit Adelaide's climate and bring back more native plants, birds, bats and butterflies, he says.

Thicker levels of understorey would encourage more fauna, albeit some noxious animals including European wasps and snakes. "Unfortunately, there is a perception that these things are undesirable in the parklands."
