Alien conifers have been widely planted in the Southern Hemisphere. Australia, New Zealand and South Africa, all with long histories of alien conifer planting, have major problems with invasive conifers (“wildings”). Widespread planting of alien conifers has a much shorter history in South America, and invasions are a recent phenomenon. A workshop was convened in Argentina in May 2007 to discuss the rapid emergence of problems with invasive conifers in South America. Workshop delegates agreed that: the problem is likely to increase substantially and rapidly in many parts of the continent; the problem is not widely recognized; lessons from elsewhere can be transferred; and collaboration can bring benefits. The need was expressed: for an accurate assessment of the dimensions of the problem; to raise awareness of the problem; for a common research agenda; to initiate management interventions. This paper summarizes the key aims, deliberations, and planned outcomes of the workshop.

Risk assessment, eradication, and biological control: global efforts to limit Australian acacia invasions (2011, background): “Similarly, although invasions are context dependent, valuable insights into management have been gained from different parts of the world (Richardson et al., 2008; Simberloff et al., 2010).”
Conflicting values: ecosystem services and invasive tree management (2013, background): “This may reflect the relatively early stage of South American tree invasions relative to other countries (Richardson et al. 2008; Simberloff et al. Government-funded planting of Pseudotsuga for carbon credits in land adjacent to conservation grassland On-going controversy with threats of vigilante…”
Invasion of glossy privet (Ligustrum lucidum) and native forest loss in the Sierras Chicas of Córdoba, Argentina (2010, background): “As elsewhere, non-native trees cause major ecological and economic problems in Argentina, where they have invaded protected areas in the northwest of the country, as well as remnants of natural Neotropical forests (Grau and Aragón 2000; Zalba and Villamil 2002; Richardson et al. 2008).”
Human‐mediated introductions of Australian acacias – a global experiment in biogeography (2011, background): “The ways in which different sectors of human societies perceive non-native species are becoming increasingly complex and change over time (e.g. Warren, 2007, 2008; Richardson et al., 2008a,b).”
Ecology and management of invasive Pinaceae around the world: progress and challenges (2017, background): “…and management of their invasions provides a robust framework for assessing the risk of invasions in areas where new forestry operations are planned or where afforestation is fairly recent, and where invasions may not have had time to manifest (Richardson et al. 2008; Simberloff et al. 2010).”
Biological invasions in developing and developed countries: does one model fit all? (2010, background): “However, many developing countries also rely heavily on industrial agricultural, aquaculture, and forestry cultivars based on exotics and sometimes invasive species (e.g., Matthews and Brand 2004, 2005; Richardson et al. 2008 ).”
Introduced deer reduce native plant cover and facilitate invasion of non-native tree species: evidence for invasional meltdown (2010, unknown): “This is the case for exotic conifers, many of which are highly invasive worldwide and threaten native communities in the southern hemisphere, especially in South America (Richardson et al. 2008).”
Pinus contorta invasion in the Chilean Patagonia: local patterns in a global context (2010, background): “Although alien conifer invasions in South America have not been as widespread as in some other parts of the Southern Hemisphere, their extent is increasing rapidly due to the intensification of commercial forestry and increase in human disturbances (Richardson et al. 2008).”
