Herbivory Damage and Harvest Maps
In 1998, the first coastwide nutria harvest survey was flown, as part of the Nutria Harvest and Wetland Demonstration Program.  A total of 23,960 acres of damaged wetlands were located at 170 sites along the survey transects.  In 1999, the damage increased to 27,356 acres located at 150 sites.  A slight decrease was shown in 2000 with 25,939 acres located at 132 sites.  In 2001 the damage decreased to 22,139 acres located at 124 sites.  Again, in 2002 the number of damaged acres decreased, but only slightly to 21,185 acres located at 94 sites.  In May 2004, the survey showed 69 damage sites covering 14,260 acres.  Continuing the same pattern, the 2006 survey reported 31 nutria damage sites covering 12,315 acres.  In April 2007, there were 23 documented nutria damage sites totaling 9,244 acres.  The 2009 survey reported 19 damage sites, totaling 5,422 acres.  In May 2010, the survey showed 11 damage sites covering 2,260 acres.  The 2011 survey reported 10 damage sites, totaling 1,679 acres. The 2012 survey reported 11 damage sites, totaling 1,129 acres.  The April 2013 damage survey reported 12 damage sites, totaling 1,233 acres. The 2014 survey reported 11 damage sites, totaling 1,115 acres. When extrapolated to a coastwide estimate, the acres impacted over these years ranges from 102,585 to 4,181 acres (damaged acres X 3.75).  The 3.75 multiplication factor comes form the area actually surveyed along transect lines (0.5 miles) and the distance between transect lines (1.87 miles).
