Potential Impacts of Climate Change on Habitats and Their Effects on Invasive Plant Species in Danube Delta Biosphere Reserve, Romania

Abstract

In climate change context, in Danube Delta Biosphere Reserve (DDBR) changes have occurred in habitats and species distribution. Invasive species were identified in the Natura 2000 habitat types 1210, 1310, 1410, 1530* (Priority habitat according to annex 1 of the European Habitats Directive (92/43/EEC)), 2110, 2130*, 2160, 3130, 3150 and 91E0*. Moreover, 21 plant communities mainly consisting of alien plants were recognised in the field. The spreading potential of invasive species is greater in the fluvial delta in the western part of DDBR. Taking into account the climate change pressures and species features, a map of invasive species spreading potential was produced in order to be used for new management and control measures. The biggest challenge is the uncertainty of long-term effects on the measures taken under current climate change conditions.
