Abstract

We develop a modelling approach for the optimal spatiotemporal control of invasive species in naturalprotected areas of high conservation value. The proposed approach, based on diusion equations, isspatially explicit, and includes a functional response (Holling type II) which models the control rateas a function of the invasive species density. We apply a budget constraint to the control programand search for the optimal eort allocation for the minimization of the invasive species density. Boththe initial density map and the land cover map used to estimate the habitat suitability to the speciesdiusion, have been generated by using very high resolution satellite images and validated by means ofground truth data. The approach has been applied to the Alta Murgia National Park, one of the studysite of the on-going H2020 project ECOPOTENTIAL: Improving Future Ecosystem Benets ThroughEarth Observations' (http://www.ecopotential-project.eu) which has received funding from the EuropeanUnion's Horizon 2020 research and innovation programme under grant agreement No 641762. All theground data regarding Ailanthus altissima (Mill.) Swingle presence and distribution are from the EULIFE Alta Murgia Project (LIFE12 BIO/IT/000213) titled Eradication of the invasive exotic plant speciesAilanthus altissima from the Alta Murgia National Park funded by the LIFE+ nancial instrument ofthe European Commission.
