Great work!

And their ecological impacts are much more widespread and diverse than is often communicated. Here, I try to put the record straight. I do so while describing a recent paper of ours that introduces a new categorisation of 19 impacts types that invasive species have across ecological hierarchies.

Our take-home message from this detection is this:
6/6
It took EAB less than 30 years to successfully invade Canada. The first infestations in Windsor, Ontario likely established in the late 1990s and we hypothesise that EAB invaded Vancouver prior to 2020. Our finding suggest that other, undetected populations of emerald ash borer may exist in other jurisdictions between those in western North America and the wellestablished populations in eastern North America. The quick identification of initial adult in Vancouver 2023 and subsequent delimitation efforts that we document here shows that the collaborative efforts of Canada’s National Plant Protection Organization (i.e., the CFIA), researchers and municipalities to manage EAB can have positive outcomes in the remaining areas of Canada where the insect has not yet been detected. The reporting of the initial adult by Mr. Short also highlights the role of public involvement in invasive species detection (Price-Jones et al. 2022; Roe et al. 2024). That EAB has been in Vancouver for some time suggests efforts in Canada to mitigate the spread of EAB had low effectiveness (Hope et al. 2021). The obvious success of a population in Vancouver, and the continued existence of a population in Winnipeg, Manitoba and other communities in Canada, also suggests that recent development models (Barker et al. 2023) for EAB may be inadequate for making predictions about the potential range of EAB in Canada.
