Beautiful, isn’t it, looking south into the valley from the Larapinta trail, just east of Simpson’s Gap, in the late afternoon light.
Trouble is, under these shrubs and trees lurks thick, dense buffel grass, square kilometers of it, healthy and in seed, a tinderbox in the making.
Territory authorities are not losing any sleep about this – in sharp contrast to our southern neighbour which has a “state-wide strategic approach to minimising the impacts of buffel grass”.
As it dries out in the approaching summer, buffel will ignite, as it has done countless times before, from lightning or arsonists. Its ferocious blaze will destroy native grasses as well as tree and shrub seedlings, continuing to colonise the best parts of the West MacDonnell National Park, the backbone of Alice Springs’ tourism industry.
Instead of the splendid native flora, visitors will come to see a monoculture of an introduced species brought in decades ago by CSIRO – then unaware of its impacts – to control dust and as cattle fodder.
While the NT Government, like all its predecessors, is doing absolutely zero about this, South Australia is stepping up its containment effort. A team is currently surveying the spread in the APY Lands south of the border.
In the Strategic Plan 2012-2017, SA Minister for Sustainability, Environment and Conservation, Paul Caica, doesn’t mince his words: “The task to reduce the threat of buffel grass across the State is considerable, requiring a collaborative approach to manage infestations and contain its spread,” he says.
“This will rely on cooperation between land managers, Traditional Owners, and all members of the broader community involved in this important environmental management issue.”
The strategy report says: “Buffel grass (Cenchrus ciliaris) has been listed among species of ‘extensive continental distribution’ that are ‘capable of destroying’ Australian ecosystems (Humphries et al. 1991).
“Buffel grass is arguably the single greatest invasive species threat to biodiversity across the entire Australian arid zone, and without active management it will continue to invade a wide range of native habitats to the extent that it would replace many native species in those habitats.
“Buffel grass is noted for its impact on threatened species in the APY Threatened Species Recovery Plan, and in the Rare and Threatened Flora Management Plan for the APY Lands.
“Buffel grass is rated as ‘very high’ on the weed control list for rangelands in the Weed Management Plan for the northern and Western Region of the Department for Planning, Transport and Infrastructure.”
The Alice Springs News Online is seeking comment from NT Parks Minister Bess Price and will report further on the SA survey in the “Pit Lands”.
