New signs have been erected along roadsides in the SA Murray-Darling Basin (SAMDB) region to mark infestations of buffel grass, an introduced, invasive perennial grass.
Project coordinator, Natural Resources SAMDB District Officer Dwayne Godfrey, said the signs are an important initiative to encourage people to avoid driving through buffel grass infestations, which encourages the weed to spread.
“Natural Resources SAMDB district officers have been working to mark all 51 known sites where the weed occurs,” Mr Godfrey said.
“The signs have been erected to help increase awareness of known infestations so that contractors, council workers and those who drive along roadsides avoid slashing, mowing or driving through buffel grass.
“The signs will also increase visibility of the sites so we can do control works and monitor them annually.
”Buffel grass forms dense monocultures that cause habitat loss and displace native vegetation by competing for water and nutrients, and the weed is present from the Riverland through to Tailem Bend.
“It forms a continuous, flammable ground layer that can carry hot fires, affecting native flora and fauna and threatening infrastructure and public safety.
“Neighbouring landholders and councils have been informed about where these patches are so they can help us keep an eye on them too.”
Mr Godfrey said if people think they have seen buffel grass they should photograph it or take a sample of leaves, stems and grass heads, take note of the exact location and inform their local Natural Resources SAMDB District Officer.
“Working together is how we will successfully contain the spread and destroy buffel grass infestations in the SAMDB region,” Mr Godfrey said.
