We used number of hectares of vegetation in poor condition (>5% cover of introduced plant species) due to the presence of introduced plant species as a measure of candidate-action performance toward this management objective because workshop participants considered this level of cover likely to cause negative impacts and trigger a management response. Introduced plant species management in the Australian Alps We applied the decision framework to identify optimal strategies for managing multiple introduced plant species in two areas in the Australian Alps: alpine and subalpine areas of the Victorian Bogong High Plains (BHP) (36.9333° S, 147.3000° E) and New South Wales' Kosciuszko National Park's main range alpine area (KNP) (36.4492° S, 148.2672° E). Effectiveness is expressed as the proportion of impact remaining after management compared with the do-nothing case that results in the maximum impact and has no cost gl Species and actions identified for management changed with budget (Figure 3).
