Agricultural Production with Change and Uncertainty: A Temporal Case Study Simulation of Colorado Potato Beetle AgEcon
Heikkila, Jaakko; Peltola, Jukka.
Changes in climatic and policy environments combined with uncertainty related to stochastic environmental fluctuations make design of invasive pest policy challenging. These external changes are often exacerbated by changes in the species characteristics. We discuss facing local change and uncertainty when deciding ex ante on a specific policy strategy. Our empirical case deals with an invasive agricultural pest, Colorado potato beetle, and agricultural production in Finland. Invasions are modelled as temporally random events and stochasticity in key variables is built into the analysis. The viability of two specific policy options is evaluated given uncertainty and local change.

Assessment and Management of Invasive Alien Predators Ecology and Society
Park, Kirsty; University of Stirling; k.j.park@stir.ac.uk.
Although invasive alien species have been identified as the second greatest threat to biodiversity after habitat loss, characterizing and quantifying their impacts on native species and habitats remains a fundamental problem in conservation biology. Here, I review the techniques that are currently used to assess the impact of invasive alien species on biodiversity, highlighting both their uses in invasive species ecology and their limitations in establishing a causal relationship. Adopting a hypothesis-driven experimental approach to impact assessment, and to eradication efforts through adaptive management, would benefit our ecological understanding of invasive species without delaying critical management action that could reduce the spread of invasive...

Ecology of naturalized invasive species Lindernia dubia (L.) Pennell in the Netherlands Naturalis
Simons, E.L.A.N.; Jansen, M.G.M..
Lindernia dubia (L.) Pennell, a North American species, is still a rare and ephemerical neophyte in the Netherlands, but is invading the country rapidly now. We expect it to become a threat to plant biodiversity in Dutch wetlands. To describe its ecological and phytosociological position and assess its possible risk status we investigated known sites in the Netherlands. Being a pioneer species on open, muddy soil, more or less rich in nutrients, more or less acid, it occurs in different phytosociological classes: Littorelletea uniflorae, Phragmitetea, Isoeto-Nanojuncetea and Bidentetea tripartitae. We consider the species as possibly harmfull to vegetations belonging to the Littorelletea uniflorae and some associations of the Isoeto-Nanojuncetea, as those...

Effect of pines removal and soil litter treatments in the restoration of natural grasslands invaded by Pinus halepensis Boletín de la Sociedad
Cuevas,Yannina Andrea; Zalba,Sergio Martín.
Effect of pines removal and soil litter treatments in the restoration of natural grasslands invaded by Pinus halepensis. Ernesto Tornquist Provincial Park (Sierra de la Ventana, Buenos Aires, Argentina) protects a remnant of pampean grasslands and is seriously threatened by the spread of alien woody plants, among them by Pinus halepensis. The effect that this species has on the structure and functioning of the ecosystem lead to the implementation of control actions aimed to reduce invasion. This work presents the results of monitoring the recovery of native grasslands after two control strategies: complete and partial removal of invasive trees, with and without complementary restoration actions (removal of needles, soil disturbance, addition of top-soil...

Predicting the Benefits of Banana Bunchy Top Virus Eradication in Australia AgEcon
Cook, David C.; Liu, Shuang; Edwards, Jacky; Villalta, Oscar; Aurambout, Jean-Philippe; Kriticos, Darren J.; Drenth, Andre; De Barro, Paul J..
Benefit cost analysis is a tried and tested analytical framework that can clearly communicate likely net changes in social welfare from investment decisions to diverse stakeholder audiences. However, in a plant biosecurity context, it is often difficult to predict policy benefits over time due to complex biophysical interaction between invasive species and their hosts. In this paper, we demonstrate how benefit cost analysis remains highly relevant to biosecurity decision-makers using the example of a plant pathogen targeted for eradication from banana growing regions of Australia, banana bunchy top virus. We develop a partial budgeting approach using a stratified diffusion spread model to simulate the likely benefits of eradication to the banana...
