Systematic mapping of the evidence on the impacts of invasive plant species

In this project, we aim to systematically compile and map evidence on the individual and cumulative impacts of invasive plant species. We first developed a reproducible protocol to compile the available evidence systematically, which we are now applying to a set of plant species invasive to foreshore and riparian ecosystems in British Columbia.

The front page of our protocol Invasive species are one of the main threats to biodiversity. However, the impacts of invasive species are often investigated in isolation, even though one invasive species might increase or mitigate the impacts of others (i.e. cumulative impacts). Although cumulative impacts have long been studied within other environmental contexts, research on the cumulative impacts of invasive species is comparatively scarce.

Goals

(1) Develop a reproducible protocol to systematically compiling the evidence on the individual and cumulative impacts of plant invasive species.



(2) Apply and test this protocol to systematically map the individual and cumulative impacts of 9 plant species invasive to foreshore and riparian ecosystems in British Columbia.
