  • Invasive species have caused major disruptions to ecosystems worldwide. The European green crab invaded North America in the 1800s and is considered one of the world’s 100 worst invaders by the IUCN. Observations of spatiotemporal green crab population dynamics are essential for predicting and managing the ecological and economic impacts of this harmful invasive species. These data come from a standardized method for assessing green crab population dynamics in the rocky intertidal zone of New England and Atlantic Canada. Data was collected from 10 survey sites located along the coast of Maine from Yarmouth, ME (furthest point south), to Walpole, ME (furthest site north) from January, 2018 to November, 2023. Data was collected following the survey design described in McMahan (2020), using a 1m^2 quadrat to sample rocky intertidal habitat. The resulting data collected using this protocol has a wide range of uses, including to inform ecological research, conservation efforts, mitigation strategies, and fishery development, as well as for educational outreach purposes.
