From 1998-2002, surveys flown by the Nutria Harvest and Wetland Demonstration Program observed up to 170 damage sites and estimated as much as 102,585 acres of damaged wetlands.

Since implementation of the Coastwide Nutria Control Program in 2002-2003, the number of damage sites has been as few as 10 sites and coastwide estimated damage as low as 4,181 ac. Nutria damage is heavily correlated with the number of nutria harvested in previous seasons and low harvest since the 2016-2017 season has resulted in 25 damage sites and estimated 14,652 ac of damage coastwide.
