Feedbacks underlie the resilience of salt marshes and rapid reversal of consumerâdriven dieâoff
Understanding ecosystem resilience to human impacts is critical for conservation and restoration. The largeâscale dieâoff of New England salt marshes was triggered by overfishing and resulted from decades of runaway crab grazing. In 2009, however, cordgrass began to recover, decreasing dieâoff â¼40% by 2010.
