Vulpia species (Vulpia bromoides, Vulpia myuros) are annual grass weeds prevalent in southern Australian, dryland pastures. Vulpia provides poor quality forage and its seeds damage hides, carcasses and skins. Knowledge on how shading affects Vulpia growth and survival can be used to develop grazing ...

A common approach for improving the efficacy of weed management has focused on better understanding demography in order to identify vital rates or life history stages that result in the greatest reduction in population growth rate. For Scotch broom (Cytisus scoparius L.), the traditional...

Acaciella angustissima (syn. Acacia angustissima) (white ball acacia) and Aeschynomene paniculata Willd. ex Vogel (pannicle joint vetch), were rejected for release after their identification as potential weeds in pasture evaluation trials. These plants are now targeted for control and, where...

Lantana camara is a recognised weed of national and world-wide significance due to its extensive distribution and its impact on primary industries, conservation and biodiversity. However, no attempt to date has been made to carry out any population viability analysis (PVA) studies on the weed,...

Koster's Curse (Clidemia hirta (L.) D. Don) is a highly invasive shrub which has the potential to become a major weed in many parts of Queensland and elsewhere in Australia. C. hirta is perennial, can grow to 5 m in height and mature plants are capable of producing in excess of 500 berries annually ...

This paper pinpoints the South African source population(s) of fireweed and reveal if admixture has occurred. This is achieved by genotyping plants sampled from across the Australian and putative South African ranges for a combination of nuclear and chloroplast microsatellite markers. Additionally, ...

Early results (to 6.5 y) of a provenance trial of Chukrasia planted in 1999 at Berry Springs, some 50 km S of Darwin in the Northern Territory (NT) with a mean annual rainfall (MAR) of ca. 1900 mm (mostly during November to March), show great variation among provenances in growth, bark, crown...

Many herbaceous legumes are important economic plants that have also become a common component of the naturalised flora of temperate Australia. They have successfully infiltrated natural ecosystems, but species differ in their ability not only to naturalise but also in their weed impact. The level...

Lord Howe Island (LHI) is a World Heritage listed area with 240 species of indigenous vascular plants, high levels of endemism and many unique habitats. In 1984, 173 exotic plant species were listed on LHI and today there are at least 218. One of these species, Formosa lily (Lilium formosanum...
