Everglades Vulnerability Analysis

The Everglades Vulnerability Analysis (EVA) is a series of connected Bayesian networks that models the landscape-scale response of indicators of Everglades ecosystem health to changes in hydrology and salinity on the landscape. Using the uncertainty built into each network, it produces surfaces of vulnerability in relation to user-defined ‘ideal’ outcomes. Currently, the EVA can model Everglades vegetation dynamics, sawgrass peat accretion and subsidence, American alligator (Alligator mississippiensis) nesting, and wading bird colony sizes. Additional indicators may be available in the future.
