Biological control of weeds: an analysis of introductions, rates of establishment and estimates of success, worldwide (2018, background): “Numerous studies have demonstrated the effectiveness of CBC of weeds, both in terms of biocontrol agent impact on the target weed as well as economic returns from the reduction in weed populations (Clewley et al. 2012; De Groote et al. 2003; Page and Lacey 2006; van Wilgen et al. 2004).”
Changes in forest structure and species composition following invasion by a non-indigenous shrub, Amur honeysuckle (Lonicera maackii) (2008, background): “…commerce, and human health (Sumner 2003), and they are also profoundly detrimental to natural areas, which have innate ecological value and provide free ecosystem services such as regulation of climate, regeneration of soil fertility, and decomposition of wastes (van Wilgen et al. 2004).”
An economic assessment of the contribution of biological control to the management of invasive alien plants and to the protection of ecosystem services in South Africa (2010, background): “…2005; Culliney 2005; De Wit et al. 2001; Jarvis et al. 2006; Law 2007; McConnachie et al. 2003; Pimentel et al. 2005; Pringle and Heunis 2006; van Wilgen et al. 2000, 2001, 2004; van Wyk and van Wilgen 2002) have discussed or assessed the economic returns on investments in biological control,…”
The biological control of aquatic weeds in South Africa: Current status and future challenges (2017, background): “Where the benefits of a biological control programme have been measured, it has focussed on economic benefits (e.g. Van Wilgen et al. 2004).”
Seed banks of invasive Australian Acacia species in South Africa: Role in invasiveness and options for management (2008, background): “The estimated cost to clear the alien plant invasions in South Africa is around US$ 1.2 billion, or US$ 60 million per year for 20 years (Van Wilgen et al., 2001).”
Benefits of Classical Biological Control for Managing Invasive Plants (2005, background): “…have concentrated their efforts on other, operational tasks, such as identification, testing, release, and establishment of agents, and have tended to neglect post-establishment monitoring of agents and evaluation of program effectiveness (McEvoy and Coombs, 1999; van Wilgen et al., 2004).”
Economic evaluation of the successful biological control of Azolla filiculoides in South Africa (2003, unknown): “When both on-site and off-site (market and nonmarket) values, most often external to the land-owner, are included, benefit–cost ratios can be much higher (e.g., De Wit et al., 2001; Van Wilgen et al., 2003 ).”
