Community scientists take on an invasive species
Rural communities, like Fogo Island, often lack information that is specific to their place. Scientific research is conducted by experts in their field who are not embedded in the intricacies or exceptions of a specific location.
The truth is that nobody knows a place like the people who live there. This is the simple idea that lies at the root of community science, which fosters a more grassroots approach to scientific research. By connecting community members to relevant research projects, it leverages local knowledge, skills, and experiences to reach community-centred solutions.
Through our community science initiatives, we aim to enrich the information available on Fogo Island’s environment. We provide community members the training and tools needed to collect and share data that can make a real difference in preserving our natural world.
One of these initiatives is the green crab monitoring program, launched in 2024 with the help of Kiley Best of the Marine Institute, the Department of Fisheries and Oceans Canada (DFO), and dedicated community members.

The Invasive Green Crab: Why Does it Matter?
Green crab is an invasive species that is native to Europe and North Africa. It started appearing around the Atlantic shores of Canada in the 1950s, making its way to Newfoundland in 2007.
Its negative impact on our ecosystem is both ecological and socio-economic — ecological, because it damages marine habitats and feeds on native animals, and socio-economic, because it can potentially disrupt our fishing industry through aggressive behaviour towards species essential to the fishery, like lobsters and juvenile finfish.
Considering this impact, it’s essential to limit their spread in order to protect the future of Fogo Island’s environment and economy.

From Awareness to Active Removal on Fogo Island
Our monitoring program on Fogo Island began almost as a fluke. In early 2024, Fisheries Biologist Kiley Best of the Marine Institute led a presentation on green crab on the island for community members, fishers, and representatives of the Fogo Island Co-op. The purpose of the presentation was to raise awareness and share knowledge on the invasive species. While green crab had been identified in other parts of Newfoundland, it had never been spotted in the waters around Fogo Island.
After that presentation, Kiley suggested green crab monitoring as a community science program to our Environmental Stewardship team. The expectation was far from finding green crab, but rather to engage and educate community members on the practices and tools required to trap invasive species. The program’s main goal would be awareness.
In summer of 2024, our team launched the program with a handful of volunteers in different communities. We provided each volunteer with Fukui traps (multi-species traps from Japan), rope, bait, a log book, and an experimental license issued by DFO. No green crabs were found, but the program proved a successful way to engage Fogo Islanders in community science.
Everything changed in the fall of that year when fisher Kevin Ford trapped around 27 green crabs in the community of Island Harbour. Around the same time, green crab was also detected near Twillingate and around Change Islands. The teenager from Change Islands who found the crab, Brody King, was even named Newfoundland and Labrador’s first Ocean Hero of the Year by the World Oceans Day committee.
This changed the purpose of our program from awareness to prevention and active removal. It also led DFO to declare Fogo Island, and the wider Notre Dame Bay area, as an area of interest for green crab. In 2025, we maintained a small pool of volunteers throughout different communities. While the team remained small, their activities grew exponentially with hundreds of green crabs being trapped over the summer. Some of the volunteers are children from the community who are excited to check their traps every day, eager to share their learnings with their classmates and neighbours.

One of the island’s most prolific volunteers is Janet Facey, a teacher at Fogo Island Central Academy. Janet joined the program as a fun summer activity for her to do with her kids (aged 7 and 11).
“I’m the green crab lady,” she laughs while pulling out green crabs from a trap set near the canal in the community of Fogo, where she lives, “I’m a little bit obsessed. It’s exciting to track how many you get.”
Janet has trapped almost 900 green crabs, mostly from the same spot in Fogo. “Once we started catching them, we tried being strategic about it and trying different areas to find hotspots,” she says.
Beyond being an immersive way of teaching her kids about the ocean, Janet explains that it has allowed her to engage with many community members who are curious about what she’s trapping. She always explains to them what green crab is and why it matters, adding that it’s helped raise awareness and interest in green crab monitoring. Since she traps near a vacation rental, it’s also drawn the curiosity of tourists and visitors to the island.

An Ongoing Initiative
Shorefast’s green crab monitoring program is a testament to the power of community science. The dedication of our volunteers shows the love and care Fogo Islanders bear for their environment. The program places them at the forefront of our preservation initiatives and relies on their time, skills, and knowledge to protect our ecosystem from this invasive species, which would never have been discovered if it wasn’t for our community members.
As the program evolves, we’re working with DFO to explore its potential expansion. We hosted the Indian Bay Ecosystem Corporation (IBEC) for a workshop to deepen our knowledge of green crab monitoring. IBEC is conducting research on the green crab in various parts of Notre Dame Bay. Their project is fully funded by DFO as a response to an increase in green crab found in eastern and north-eastern Newfoundland. Currently, our removal plans for the green crabs include turning the trapped species into compost that community members can use for their gardens.
We’re grateful to our volunteers, the Marine Institute, and the DFO for our ongoing partnerships.
