Emergency translocation success as Mala return to NewhavenRead more...
Newhaven has relatively few weeds. However, two of central Australia’s most significant weeds occur on the property: Buffel Grass (Cenchrus ciliaris) and Couch Grass (Cynodon dactylon).
Buffel Grass (Cenchrus ciliaris) can withstand long periods of drought and frequent fires. It inhibits germination of native species, reducing biodiversity, and “infills” between Spinifex clumps, thus encouraging the spread of fire and increasing its intensity. AWC’s management aim is to control and reduce the spread of Buffel Grass by focusing control measures, including treatment with glycophosphate, on high activity areas such as the campground surrounds and road edges.
Couch Grass (Cynodon dactylon) is moisture dependant and is established around bores. Its total area of occupancy on Newhaven is currently only 2.5 hectares. If not controlled, Couch Grass has the potential to spread to the fringes of claypan and saltlake areas where it will displace important natives such as Yalka (Cyperus bulbosus), which produces small underground bulbs that are an important food source for mammals such as the Spinifex Hopping-mouse (Notomys alexis). AWC control measures are designed to reduce and eradicate Couch Grass.
