Pathway diagram for the Great Dismal Swamp state-and-transition simulation model. The boxes represent the state types and the lines with arrows represent the possible transitions. The different colored lines signify the different transition types. The blue arrows indicate a strata change from Dry to Wet due to restoration (hydrologic re-wetting). The brown arrows indicate a strata change from Wet to Dry due to managed draining or prolonged drought. The Dry strata represent a vulnerable system at risk of catastrophic fire and hurricane events
