Using strategically applied grazing to manage invasive alien plants in novel grasslands
TL;DR: It is found that grazing stock can be used to manipulate species composition in favour of the desirable components in pastures, but whether grazing is rested or strategically applied depends on the management goal, sizes of populations of the IAP and more desirable species, and climatic and edaphic conditions.
Journal ArticleDOI
The current and future potential geographical distribution of Hyparrhenia hirta
V. K. Chejara,Darren J. Kriticos,Paul Kristiansen,Brian M. Sindel,Ralph D Whalley,Christopher Nadolny +5 more
TL;DR: Chejara et al. as discussed by the authors investigated the impacts of climate change on the potential global distribution of Hyparrhenia hirta, based on eco-physiological data and found that 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.
Journal ArticleDOI
Disturbance governs dominance of an invasive forb in a temporary wetland
TL;DR: Competition and disturbance are evaluated as mechanisms governing dominance of Phyla canescens (hereafter lippia), an invasive perennial forb from South America, in Paspalum distichum (perennial grass, hereafter water couch) meadows in floodplain wetlands of eastern Australia.
Journal ArticleDOI
Factors Affecting Germination of Coolatai Grass (Hyparrhenia hirta)
TL;DR: Results indicate that Coolatai grass seeds can germinate over a wide range of diurnal temperatures, light regimes, pH levels, and under marginal water stress, and provide evidence that this species is capable of establishing in many parts of Australia.
