Justification for EICAT assessment


Acacia dealbata caused a decline in native species diversity, richness and plant cover, as well as changed soil composition (Lazzaro et al., 2014; Kamutando et al., 2019; Lorenzo et al., 2012; Vundla, 2018; da Silva et al., 2019; Souza-Alonso et al., 2015; Fuentes-Ramírez et al., 2010; Ahmad et al., 2003). Allelochemicals released led to reduction in bacterial richness and diversity (Lorenzo et al., 2013), and fungal richness and diversity was reduced (Lorenzo et al., 2010). Insect abundance and species richness declined in invaded areas (Rodríguez et al., 2020; Coetzee et al., 2007), as well as bird diversity (da Silva et al., 2019).

Countries of most severe impact
Chile; Italy; NW Iberian Peninsula; Portugal; Spain; South Africa
Description of impacts
Impact categories ranged from minimal concern to major. A. dealbata often changed chemical properties of soil or had poisoning/toxic impact on invaded environment. A. dealbata also had indirect impacts impacts on groups such as pollinators, plants and herbivores. A. dealbata changed physical and structural properties of the environments it invaded. Competition also common as A. dealbata competes for resources with native species.
