The value of recreational fisheries - which provide both cultural and a provisioning services - depends upon many factors, including water quality, geography, human management (e.g. stocking), and the value that beneficiaries place on fishing. We developed a model that predicts the likelihood that trout and other game fish are present in Adirondack ponds based on pH and stocking, and which calculates the expected value of the fishery based on this likelihood. The two interactive visualizations below implement this model and allow the user to explore how the value of recreational fisheries may change over Time and Space under multiple scenarios of recovery from acid deposition (from 0-100% recovery). Recovery scenarios were calculated using PnET-BGC. Default values for recreational fishing services were derived from Boyle (1999) and translated to 2015 dollars using the U.S. Department of Labor Bureau of Labor Statistics inflation calculator.
The plot (below) shows the simulated average expected value (GAM smoother + 95% confidence intervals) of the recreational fishery at 21 lakes measured by the ALSC from 2000 to 2200.
