Crynodeb

To identify the extent and true underlying driving forces is essential to understand processes behind biological invasions and generate policy initiatives contrasting invasion threats to biodiversity. Woody invasion by Acacia dealbata is a major process occurring and forecasted in Portuguese mountain landscape (Fernandes et al. 2014). This study tried to improve comprehension on woody invasion by Acacia dealbata using WorldView2 very high resolution (VHR) data. Three main questions were addressed: 1) Can we identify accurately dominant woody invasion processes from space with VHR data under object-oriented paradigm? 2) What spatial distribution models (SDMs) tell us about woody invasion? Observed vs Predicted 3) Which are predominant bio-physical patterns of woody invaded areas?
