OLIVEIRA-COSTA, Jorge; FIGUEIREDO, Albano; ALMEIDA, António  y  NUNES, Adélia. Characterizing the Acacia invasions in Arouce River (Lousã, Portugal) since 1960 using species distribution, land cover change and environment physical characters: implications for invisibility. GOT [online]. 2016, n.10, pp.241-265. ISSN 2182-1267.  https://doi.org/10.17127/got/2016.10.012.

The results about invasiveness in the Arouce Watershed (Oliveira-Costa & Souza, 2015), have suggested that the colonization of the region by the Acacia occur in a possible way: coming from the central area and disseminating to lower stream of the Arouce River. According the local invasiveness, the environmental conditions for Acacias in the study area are favorable (invasibility). This study is approached by analyzing the environmental conditions, through informations about species distributions and physical elements. The applied methods include analysis of orbital images and land cover maps. In the last 50 years, the two Acacias in the study area (A. dealbata and A. melanoxylon) have been improving their local range, under patterns promoted by local conditions.
