Purple Marsh Crabs Impacting Marsh Decline
October 6, 2017
Providence Journal: The small stature of the purple marsh crab belies its impact on New England’s salt marshes.
It measures only about an inch across, but through a chain of effects caused by humans, the voracious little crustacean is munching its way through the region’s vital marshes, leaving in its wake barren mud flats dotted with burrows.
“They’re fairly formidable creatures,” Brown University ecologist Mark Bertness says.
