The role played by exotic plants in urban ecosystems: comments on Spennemann, 2019

Abstract

The article written by Dirk HR Spennemann, and published in the European Journal of Ecology, addresses the role played by a palm tree species native to the Canary Islands as food source for several frugivore species found in Australian cities. This palm tree bears fruit throughout the year; therefore, it is a reliable food source in winter and helps increasing wildlife support. Spennemann avoids the native versus exotic dogmatic simplism; instead, he assesses the palm tree species based on its positive environmental impact.
