“…These studies were used to drive policy and change in the region as scientific and governance challenges have been explored. Many physical science studies attempt to understand the ecological history of the lakes by studying benthos (Burlakova et al, 2021), sedimentary records (Sgro & Reavie, 2018), species studies (Stacy-Duffy et al, 2021;O'Shaughnessey et al, 2021), and phytoplankton data (Allinger & Reavie, 2013;Estepp & Reavie, 2015). However, many scientific studies do not acknowledge or include Traditional Knowledge (TK) or important ecosystem, social, and cultural dimensions.…”

<p>This paper explores differences in opinions in the 2021 International Joint Commission (IJC) Great Lakes survey. Indigenous responses are compared with the full survey responses. Lake-wide comparisons are made between Indigenous respondents residing within different basins.</p> <p>Responses from the Province of Ontario are also analyzed at the postal-code level where a regression kriging model is built to predict responses and evaluate relevant variables for questions related to drinking water access and trust in wastewater treatment. This paper finds there are differences pertaining to concerns, opinions on severity of impacts, potential participation for protecting the health of the lakes and demographic variables that were seen between Indigenous respondents and the full survey averages. There was also differences Lake-wide in how Indigenous respondents felt about the ways in which they engage with the Lakes being threatened, as well as species of cultural importance being threatened due to the state of the Lakes. Huron and Superior respondents reported less concern, whereas Michigan, Erie and Ontario respondents reported higher concern. In Ontario, there was a contrast in the North and South pertaining to drinking water access for both the respondent and the respondent’s community, as well as perceptions in effective wastewater treatment. The North reported more disagreement with fair access to clean drinking water for both the respondents and the community, and less trust in the community’s wastewater treatment despite low response rates compared to the South.</p>

“…The rusty crayfish is native to the Ohio River drainage in the north central USA but has been introduced to at least 18 states and two provinces, likely through live bait-related introductions (Lodge et al 2000), and although the invasive status and native range of this species is contentious in many regions (Guiaşu and Labib 2021), it has certainly expanded its range since the 1960s (Olden et al 2006;Phillips et al 2009b;Smith et al 2019). Rusty crayfish are established in all of the Great Lakes and many smaller lakes within the ecoregion (Peters et al 2014;O'Shaughnessey et al 2021;iNaturalist contributors, iNaturalist 2022).…”

“…The red swamp crayfish is considered a warm water species (Zhang et al 2020), but has been shown to survive for months at low temperatures (Veselý et al 2015;Haubrock et al 2019), and has established populations in colder climates than its native range (e.g., Poland; Maciaszek et al 2019). Red swamp crayfish is present in the ecoregion in US waters but has yet to be found in the Canadian portion of the Great Lakes (Peters et al 2014;Smith 2018;O'Shaughnessey et al 2021), although nearshore warm areas of the Canadian Great Lakes do provide suitable habitat (Egly et al 2019).…”

Invasive species have long been recognized as a serious threat to freshwater ecosystems. This is especially true for invasive species in keystone positions in food webs that can cause major disruption and can lead to unexpected outcomes. Crayfish occupy a central trophic position and non-indigenous crayfish have been shown to substantially disrupt ecosystems they invade. Here, we assess eight non-indigenous crayfish to 21 freshwater ecoregions in Canada using a screening-level risk assessment. We found that ecoregions in Canada that were warmer and contained high native freshwater diversity were most at risk from crayfish invasions, particularly: the Laurentian Great Lakes, St. Lawrence, English-Winnipeg Lakes and Coastal British Columbia ecoregions. Four crayfish species consistently had higher scores: rusty (Faxonius rusticus), virile (Faxonius virilis), signal (Pacifastacus leniusculus), and red swamp (Procambarus clarkii). Of these high-risk crayfish, only the red swamp crayfish is not yet established in Canada but is present in US waters of the transboundary Great Lakes ecoregion. Our study is the first to evaluate the relative risks that non-indigenous crayfish pose to freshwater ecosystems in Canada.
