“…No conifer invasions were reported in Australia before the 20th century, and a comprehensive list of complaints by conservationists and others about conifer plantations in 1979 did not include invasions (Carron 1979). The earliest documented invasions by conifers were in the 1950s .…”

The history of conifers introduced earlier elsewhere in the southern hemisphere suggests that recent invasions in Argentina, Brazil, Chile and Uruguay are likely to increase in number and size. In South Africa, New Zealand and Australia, early ornamental introductions and small forestry plantations did not lead to large-scale invasions, while subsequent large plantations were followed with a lag of about 20-30 years by troublesome invasions. Large-scale conifer plantation forestry in South America began about 50-80 years later than in South Africa, Australia and New Zealand, while reports of invasions in South America lagged behind those in the latter nations by a century. Impacts of invading non-native conifers outside South America are varied and include replacement of grassland and shrubland by conifer forest, alteration of fire and hydrological regimes, modification of soil nutrients, and changes in aboveground and belowground biotic communities. Several of these effects have already been detected in various parts of South America undergoing conifer invasion. The sheer amount of area planted in conifers is already very large in Chile and growing rapidly in Argentina and Brazil. This mass of reproductive trees, in turn, produces an enormous propagule pressure that may accelerate ongoing invasions and spark new ones at an increasing rate. Regulations to control conifer invasions, including measures to mitigate spread, were belatedly implemented in New Zealand and South Africa, as well as in certain Australian states, inspired by observations on invasions in those nations. Regulations in South America are weaker and piecemeal, but the existing research base on conifer invasions elsewhere could be useful in fashioning effective regulations in South America. Pressure from foreign customers in South Africa has led most companies there to seek certification through the Forestry Stewardship Council; a similar programme operates in Australia. Such an approach may be promising in South America.a ec_2058 489..504

“…This creates a problem if elements of the paradigm need to be incorporated into the professional ethos and formal education. Carron (1979) observed that a scientific paradigm developed in Australia during the 1930s and 1940s when foresters had a mission to establish a market for their services. Carron and Bachelard (1993) and Squire ( 1993) noted that problems arose when the authority implicit within this work ethic was seriously questioned by the environmental groups.…”

“…A colonial view was that forests were perceived as an impediment to settlement (Carron 1979(Carron , 1980(Carron , 1985 but by the late nineteenth century these views had changed to concerns for conservatimi and afforestation. The value of forests as a resource was identified as more than an economic resource.…”

“…These concerns may have arisen because of the attacks, in Australia, on forest management policies and practices (Routley and Routley 1975;Carron and Bachelard 1993;Squire 1993;Mercer 1995). Carron ( 1979) claimed that the environmental movement's opposition to forestry operation in the 1960s and 1970s was due to a general social restlessness and 'disenchantment with government'.
