In 2021, researchers began placing concrete-block oyster reefs in bare eelgrass patches on Prince Edward Island; within two years biomass was about 45 times higher and 45 taxa had colonised the structures

Representative Image (AI-generated) What started as piles of concrete blocks on the seafloor off Prince Edward Island soon became a magnet for marine life. Researchers began installing the artificial oyster reefs in 2021 to test whether they could provide some of the ecological functions lost from areas where eelgrass no longer grew. Within two years, … Read more

In 2020, Ohio removed a dam from the once-polluted Cuyahoga River; it reopened 39 km of habitat, and scientists later detected 15 additional fish taxa

In 2020, Ohio removed a dam from the once-polluted Cuyahoga River; it reopened 39 km of habitat, and scientists later detected 15 additional fish taxa

An 18-metre concrete dam on Ohio’s Cuyahoga River once stopped migrating fish from reaching important spawning areas for more than a century. Today, aquatic life is quickly returning to the river. Researchers from the US Geological Survey, working with state biological agencies, have released new long-term monitoring data showing a major ecological recovery. After the … Read more
