Goose-GMSE is an interface for a population- and management model for Greenland Barnacle Geese, as described in detail in SNH Research Report 1039 - Development of a population model tool to predict shooting levels of Greenland barnacle geese on Islay.
The functions contained in gile goose_predict_gui.R are a direct implementation of the model described in the above.
The app.R file is a Shiny GUI interface which allows repeated (simulated) runs of population trajectories, given selected management inputs.
