Improving the agent selection, release and evaluation process: the role of bioclimatic modelling.
Lawson, B. E.; Klinken, R. D. van; Day, M. D.; Heard, T. A.; Zalucki, M. P.; Queensland Weed Society, Queensland, Australia, Proceedings of the 16th Australian Weeds Conference, Cairns Convention Centre, North Queensland, Australia, 18-22 May, 2008, 2008, pp 510-512, 2 ref. Climate models are frequently used to evaluate the potential distribution of introduced species. However, despite their potential value, their use in biological control remains limited. Using a number of weed biocontrol programs as case studies, we assess...

The utility of molecular marker approaches to understanding plant invasions.
Hardesty, B. D.; Westcott, D.; Queensland Weed Society, Queensland, Australia, Proceedings of the 16th Australian Weeds Conference, Cairns Convention Centre, North Queensland, Australia, 18-22 May, 2008, 2008, pp 460, 1 ref. It is known that alien or weedy species impact the composition, function, and structure of native plant populations in numerous ways including disruption of mutualisms, alteration of microsite conditions and shifts in species compositions. By combining da...

Is eradication of the invasive tree miconia feasible? Lessons from 15 years of active management in French Polynesia (Pacific Islands).
Meyer, J. Y.; Queensland Weed Society, Queensland, Australia, Proceedings of the 16th Australian Weeds Conference, Cairns Convention Centre, North Queensland, Australia, 18-22 May, 2008, 2008, pp 433, 3 ref. A small tree 4-12 m tall, native to Central and South America, miconia (Miconia calvescens) was first introduced to the island of Tahiti as a garden ornamental in 1937. It now forms dense monospecific stands from near sea-level to 1400 m elevation, displa...

The National Four Tropical Weeds Eradication Program: a case study for future weed eradication projects in the wet tropics.
Erbacher, K.; Sydes, T. A.; Galway, K. E.; Brooks, S. J.; Queensland Weed Society, Queensland, Australia, Proceedings of the 16th Australian Weeds Conference, Cairns Convention Centre, North Queensland, Australia, 18-22 May, 2008, 2008, pp 430-432, 9 ref. The national cost shared Four Tropical Weeds Eradication Program has been operating since 2001. This program targets Clidemia hirta, Limnocharis flava, Mikania micrantha and Miconia spp. This paper presents an overview of the procedures and challenges ass...

Eradication versus long-term surveillance and removal: contrasting approaches to Chrysanthemoides monilifera (L.) Norlindh management in Australia.
Cherry, H.; Queensland Weed Society, Queensland, Australia, Proceedings of the 16th Australian Weeds Conference, Cairns Convention Centre, North Queensland, Australia, 18-22 May, 2008, 2008, pp 427-429, 7 ref. Outlier infestations of widespread weeds are likely candidates for eradication or long-term surveillance and removal. Eradication programs may take years to complete, but should have projected end dates. In contrast, surveillance and removal programs must...

Processes leading to the detection of tropical weed infestations during an eradication program.
Brooks, S. J.; Galway, K. E.; Queensland Weed Society, Queensland, Australia, Proceedings of the 16th Australian Weeds Conference, Cairns Convention Centre, North Queensland, Australia, 18-22 May, 2008, 2008, pp 424-426, 8 ref. We identify and track processes that have resulted in the detection of six tropical weeds targeted for eradication. The habitats and distributions of these species make detection by field officers and members of the public more likely than targeted search...

Optimal frequency for woody weed management for North Queensland grazing properties: an economic perspective.
Zull, A. F.; Lawes, R. A.; Cacho, O. J.; Queensland Weed Society, Queensland, Australia, Proceedings of the 16th Australian Weeds Conference, Cairns Convention Centre, North Queensland, Australia, 18-22 May, 2008, 2008, pp 415-417, 5 ref. Once invasive species have colonised a landscape, they require frequent management to preserve the lands' productive capacity. However, weed management is costly, and tradeoffs exist between the frequency of weed management and the productive capacity of ...

Reducing the risk of new weed introductions through strategic engagement.
Farrer, M.; Young, S.; Queensland Weed Society, Queensland, Australia, Proceedings of the 16th Australian Weeds Conference, Cairns Convention Centre, North Queensland, Australia, 18-22 May, 2008, 2008, pp 411-413, 7 ref. Research into the spread of weeds has found ordinary gardens are a major source of new weed introductions. As part of the Victorian Government's 'Moving Forward: Making Provincial Victoria the Best Place to Live, Work and Invest' initiative, the Departmen...

Prioritising weed management for biodiversity conservation at the NRM level.
Williams, M. C.; Auld, B.; O'Brien, C. M.; Rendell, N.; Downey, P. O.; Queensland Weed Society, Queensland, Australia, Proceedings of the 16th Australian Weeds Conference, Cairns Convention Centre, North Queensland, Australia, 18-22 May, 2008, 2008, pp 408-410, 12 ref. At a regional or Natural Resource Management (NRM) region level, weed management for biodiversity conservation has often lacked strategic direction and expertise. This has led to: programs that do not necessarily deliver biodiversity outcomes; ineffective...
