Prioritising weed management activities in a data deficient environment: the Pilbara islands, Western Australia.

摘要: Along the Pilbara coast of Western Australia (WA) there are approximately 598 islands with a total area around 500 km2. Budget limitations and logistical complexities mean management these tends to be opportunistic. Until now has been no review establishment impacts weeds on or any attempt prioritise island weed management. In many instances only occurrence documented, creating data deficient environment for decision making. The purpose this research was develop database occurrences WA create prioritisation process that will generate ranked list island-weed combinations using currently available data. Here, we describe model pairwise comparison formulae in Analytical Hierarchy Process (AHP), four metrics describing difficulty working each (island size, ruggedness, travel time, tenure), two well established measures conservation value an (maximum representation effective maximum rarity eight features). We present sensitivity rankings changes weights applied criteria Kendall's tau statistics. also top 20 modelling scenarios. Many tools exist. However, require extrapolation fill gaps specific objectives dedicated budgets. To our knowledge, study is one few attempts actions where may opportunistic spasmodic due budgetary restrictions.
