GIS analysis of spatial distribution of invasive tree species in the protected natural area of Mt. Avala (Serbia)

Abstract

In this paper we present the results of studies of distribution of seven invasive tree species (Robinia pseudoacacia, Acer negundo, Fraxinus pennsylvanica s.l., Ailanthus altissima, Gleditsia triacanthos, Rhus typhina, Amorpha fruticosa) in the protected area "Avala" in Serbia. Field studies were conducted between May and July 2012. Distribution data for invasive species were collected using the GPS positioning with a GPS receiver eTrex Vista C (Garmin). Software Manifold System 5.50 Professional Edition was used for spatial data analysis and for creation of vector maps of the MGRS network with 100 × 100 m squares. We registered a total of 1019 individual occurrence data, which were distributed to 245 MGRS squares of 100 × 100 m. A detailed distribution map, resulting from the analysis of distribution in relation to the zones of protection and habitat types, is presented for each invasive species. © 2014 Institute of Botany and Botanical Garden Jevremovac, Belgrade.
