New paper: Cultural integration of invasive species

Modes of cultural integration of invasive species (IS), relative to native species

Really pleased to be part of a new (open access) conceptual paper in npj Biodiversity, Cultural integration of native species. Led by Ivan Jaric and Jonathan Jeschke with a fascinating international team, this paper describes and problematizes the implications of cultures accepting invasive species into their landscapes and livelihoods. The range of disciplines in the writing team prompted rich debates about the issues, which are only more relevant with species ‘on the move’ due to climate change. A few case studies flesh out the paper, showing for instance the impact of the cultural integration of Black locust trees in Hungary, and of prickly pear cactus in a range of different settings. Such cultural integration can limit conservation management options, especially for species not only widely recognized and accepted but that become essential to livelihoods or lifestyles (e.g., food or sport fishing) or culturally iconic (e.g. the Sable Island Horse). We hope that this review helps provide some structure for those dealing with similar issues. Thanks to all the co-authors.

Coastal Zone Canada 2025

 

Alex Legault presents his work on the Acadian diaspora and dykeland stakeholdership to CZC2025.

Athena Iraji talks about her early findings with Nancy Anningson from TransCoastal.

Four members of my team went to Coastal Zone Canada in PEI last week, and reported an excellent event. Colleagues from TranSECT and TransCoastal also participated in many sessions there. I certainly wish I could have attended, especially after I heard that A. R. Siders was the keynote. Alex Legault (above) presented his work on the Acadian diaspora, including the new plan to put the survey back in the field to try to acquire wider perspectives. Athena Iraji presented a poster on her very first results as she explores whether the timeline of the Coastal Protection Act actually expedited coastal development in the year of its passing. We’re so grateful to CZC for the support they gave Athena to attend this event. Keahna Margeson presented the results of her second PhD paper, which uses survey results around causeway sites in NB and NS to understand what drives support for river restoration. Finally Robin Willcocks Musselman presented the results of her recent paper on place and managed retreat, and introduced her empirical research plan. I hope CZC stops scheduling for the same week as IASNR, so I can attend the next one.

Saltmarsh Breakthrough

I was a minor contributor to the State of the World’s Saltmarshes 2025 report led by WWF that was launched this week at the UN Oceans Conference in France. The report aims to launch a ‘saltmarsh breakthrough’ similar to the one sparked for mangroves, drawing attention to the importance of saltmarshes in our climate future. My work with TransCoastal Adaptations and NSERC ResNet in the Bay of Fundy has in part explored the human dimensions of these important landscapes in a place where they’ve been largely converted to agricultural use through dyking and draining.

The UN Oceans Conference is just one of the conferences I’m not attending this week.  I had already been torn between the Coastal Zone Canada conference in PEI (where four members of my team are presenting) and the International Association for Society and Natural Resources in Vancouver (which I did register for and plan to attend). However, roots in my sewer line and the inevitable nasty backup mean that I’m here keeping company with members of my insurance company’s remediation team. I’m getting lovely notes from people at both events. I wish I was there, too!
