Changes in the Occurrence of Five Invasive Plant Species in Different Ecosystem Types between 2009–2018 in Hungary

Modelling and analysis of spatiotemporal characteristics plant invasion can help in mapping predicting the spread invasive plants. The aim our research was to investigate variability five common species (Ailanthus altissima, Asclepias syriaca, Elaeagnus angustifolia, Robinia pseudoacacia, Solidago spp.) within different land cover (ecosystem)-type categories. basis study National Geospatial Database Invasive Plants (NGDIP) Hungary, ecosystem types Ecosystem Map Hungary (EMH). GIS-based detailed occurrence database thematic land-cover maps (EMH) examined allow us answer question which habitat distribution given has stagnated, decreased, or increased between 2006 2018. We developed a methodology with relevant data sources demonstrated variation, be used for future management planning biology research. Our results show that syriaca pseudoacacia are increasingly threatening grasslands also spreading more intensively complex cultivated areas. occurrences Ailanthus altissima declining built-up areas due extreme environmental conditions cities modified urban planning. spp. is wetlands, biodiversity floodplain (riparian) vegetation.
