“…Although various pathogens of trees widely utilized for plantation forestry, such as species of Pinus and Eucalyptus , are commonly seed‐borne and have likely entered into new environments with such germplasm (Ioos et al., 2009; Jimu et al., 2015), rust pathogens would be unlikely to move in this way. The emergence of rust caused by E. violae‐faustiae in plantations of A. crassicarpa emphasizes the need for adequate quarantine measures to prevent the accidental introduction of new pathogens into areas where non‐native trees are being propagated for plantation forestry (Burgess & Wingfield, 2002, 2016; Healy et al., 2022).…”

“…as it is for other trees widely planted in the tropics and Southern Hemisphere such as Eucalyptus , Pinus and Populus (Burgess & Wingfield, 2016; Hurley et al., 2023; Roux & Wingfield, 2009; Wingfield et al., 2011). Broadly, the situation in all cases is that diseases as well as insect pests are some of the most economically important factors threatening the long‐term sustainability of plantation forestry utilizing non‐native tree species internationally (Healy et al., 2022; Payn et al., 2015; Wingfield et al., 2015).…”

Acacia crassicarpa is a tropical tree species native to Australia, West Papua and Papua New Guinea, which has been widely used to establish plantations in the lowland humid tropics of Sumatra and Kalimantan. These trees, able to grow on sites having relatively poor nutrition, have been relatively free of serious disease problems. A rust disease infecting the phyllodes of A. crassicarpa has recently been encountered in plantations in various areas of Indonesia and Malaysia where they are not native. In this study, the rust was collected and identified as Endoraecium violae‐faustiae using DNA sequence analysis based on the internal transcribed spacer (ITS) region of the rDNA. This is the first record of the rust outside its native range. Damage at present appears to be relatively mild but the pathogen could become important in the future.

Vietnam is the country with the largest area of plantations of Australasian Acacia species ('wattles') in South-East Asia. Between 6 and 9% of the national land area is cultivated with tropical wattles (A. auriculiformis, A. mangium and its hybrid). From the perspective of its promoters, the wattle plantation industry in Vietnam may be seen as a success beyond expectations. We review the origins of this boom and ask what it has done to and for the country's landscape and people. The chapter combines fndings and insights from an interdisciplinary research project in Thừa Thiên Huế province, north-central Vietnam. Research took place across upland and lowland wattle-growing regions, with ethnic minorities as well as the Kinh majority, and with long-term wattle growers as well as new entrants. It drew on questionnaires, interviews and observations, as well as information from remote sensing, ecological surveys and hydrological assessments. We frst describe how substantial areas of 'new forest' (short-rotation wattle plantations) were created, initially in degraded bushland, but now sometimes through clearing of highly biodiverse natural forest stands. These wattle plantations alter local hydrology, soils and biodiversity, and are exposed to risks including soil erosion and plant pathogens. The plantations provide wood chips and timber, supporting revenue, employment and a strong forestry industry. Incomes have risen appreciably for many, although unequally, and a class of successful entrepreneurs has emerged. These plantations alter the livelihoods and identities of upland 'forest people', historically shifting cultivators, contributing to what might be called 'new forest people'. Ethnic minority villagers are building new identities around the wattle economy and around their contracts with state forest agencies, seeing themselves increasingly as forest growers and protectors. We conclude by raising some questions regarding the social changes and issues of environmental sustainability linked to this wattle boom.
