Resumo
Since the 19th century, several Australian Acacia species (‘wattles’) have been introduced to the Iberian Peninsula as ornamentals, for sand and slope stabilization, for timber, or for other uses. Many species now display invasive behaviour, causing negative impacts and being the focus of management actions. Wattles are most widespread across mainland Portugal and in the north-west and south-east of Spain, particularly in coastal areas. This chapter aims to review what has been done to manage wattles in the Iberian Peninsula. We start by reviewing the literature on this subject. However, as much of the management carried out on wattles has not been published, we also present: (i) the results of a survey distributed to land managers; and (ii) five case studies that illustrate different contexts. Management of wattles (mostly A. dealbata, A. longifolia and A. melanoxylon, but also several others) began in the late 1970s. Yet, only after 2000, and notably after 2015, did control interventions become more frequent, strategic and better planned, by considering species’ characteristics and the importance of follow-up control and biological control. Wattles are now managed in conservation areas, commercial forest plantations, close to roads and railways, on communal land, and other areas. Prioritization is given to conservation goals but also to preventing fire hazard, recovering recreational value and margins of linear infrastructure, and improving forest and agriculture productivity, among others. There has been an increase in research efforts on several aspects of wattle management (mostly in control, restoration, modelling, remote sensing and use of control wastes) in the Iberian Peninsula. However, the number of studies is still low (54). Although an assessment of total management cost is yet to be made, a preliminary survey shows that cumulative costs since 2000 are well above €30 million in Portugal. Management costs, including mostly control, but also those associated with public awareness, surveillance, habitat restoration and other aspects, are supported by private and local, national and European Union public funds. Much remains to be done, but wattle management in the Iberian Peninsula has certainly taken substantial strides forward over the last few decades.
