Research project Developing a cost-efficient control program for the invasive plant Lupinus polyphyllus

To reach this aim, we will use a two-fold approach. First, we will examine in what geographic regions and under what environmental conditions that Lupinus constitute a potential problem, and thus identify in what situations actions to control the species are at all needed. Second, we will assess how cost-efficient different management practices are to reduce long-term population growth rates in areas where the species constitute a potential problem. We will both explore the situation under current conditions, and future scenarios under different assumptions about climate change. Taken together, these results provide a solid basis for a cost-efficient control program, that is not only possible to implement episodically and at small spatial scales, but that is feasible to maintain over large areas and long time periods.
