“…This grass is a valuable species at high stocking rates in Western Australia (Humphries, 1959;Rogers et al, 1979) and also can be cultivated under saline conditions (Rogers and Bailey, 1963), which may be useful to control the watertable and reduce soil salinity. Due to the fast growth rates and drought resistant condition requirements, Coolatai grass is potentially a target forage and energy crop species as it has potential to supplement the nutritional feed for animals during dry season or it can be used as biomass feedstock for energy production.…”

“…It can survive periods of drought in the summer (McWilliam et al. , 1970) and can grow on a range of soil types from light textured granitic soils to heavy black earths, and it is moderately salt tolerant (Rogers & Bailey, 1963; McCormick et al. , 1992).…”

Chejara VK, Kriticos DJ, Kristiansen P, Sindel BM, Whalley RDB & Nadolny C (2010). The current and future potential geographical distribution of Hyparrhenia hirta. Weed Research50, 174–184. Summary Hyparrhenia hirta is a pasture grass that has become highly invasive in several parts of the world, including Australia where it has become a serious environmental weed in recent decades. Knowledge of the likely potential distribution and relative abundance of this invasive species, under current and future climate scenarios, will help biosecurity and weed control authorities to plan better strategies to manage the invasion. The CLIMEX modelling package was used to investigate the impacts of climate change on the potential global distribution of H. hirta, based on eco‐physiological data. The worldwide potential distribution of H. hirta under current climatic conditions is vast and far greater than the current distribution, with suitable climate conditions extending over much of the tropics and subtropics. Under future climate scenarios, the range of H. hirta is likely to expand into areas currently too cold for its survival and contract from areas that are projected to become hotter and drier under climate change. The effects of likely climatic scenarios on the global potential distribution of H. hirta are sufficiently great that they should be considered routinely in strategic control plans for biotic invasions. Changes in the potential range of an invasive species such as H. hirta, under global warming scenarios, will mean that it could invade new jurisdictions. Knowledge of this emerging threat could help to formulate effective prevention, surveillance and response measures in these presently marginally unsuitable regions.

“…A variety of plant species, particularly exotic grasses and chenopods, have been evaluated for performance on saline sites (e.g. Rogers and Bailey 1963, Hamilton 1972, FitzGerald and Fogarty 1992, Greig 1994, Barrett-Lennard and Malcolm 1995. However, with the notable exception of some chenopods, old man saltbush (Atriplex nummularia) in particular, most of the promising species have been exotics -largely due to the lack of native material in evaluation trials.…”

Two scalded saline sites on the inland slopes of NSW were selected for an evaluation of ten accessions of warm-season stoloniferous/rhizomatous grass species: common couch (Cynodon dactylon), marine couch (Sporobolus virginicus), rats-tail couch (S. mitchellii), salt-water couch (Paspalum vaginatum), water couch (P. distichum) and one exotic, kikuyu (Pennisetum clandestinum). Most species performed well at Wagga Wagga but only common couch, marine couch and salt-water couch did at Manildra, where they consistently outperformed the other native species in terms of survival, groundcover and vigour. Salt-water couch had the highest mean vegetative cover at both sites. Differences in salinity, pH (acid cf. alkaline) and particularly topsoil moisture probably accounted for differing plant performances at the two sites. In a follow-up production study of the most successful accessions under relatively dry conditions at Manildra, the 'Yamba' accession of marine couch consistently produced more leaf/seedhead dry matter (1057 ± 172 kg/ha) during the growing season than the others. However, salt-water couch consistently produced more ex-plot stolon/rhizome dry matter (974 ± 127 kg/ha) than the other two species. This probably explained its ability, unlike marine couch, to maintain groundcover during a regime of regular cutting. Further evaluation under grazing and recreational uses is recommended. The genetic material evaluated was only a small sample of salt-tolerant native grasses. The variable performance of the four accessions of rats-tail couch, for example, suggested that more salt-tolerant types are likely to be found.
