The document discusses interfacing the Forest Vegetation Simulator (FVS), a model for forest growth and mortality developed by the US Forest Service, with the statistical programming language R. The author's goal was to use FVS for "Monte Carlo style" stochastic simulations of fire and drought events from within R. This was made possible by the Open-FVS project, which provides an application programming interface linking FVS to R. The author describes using the linked R and FVS system to batch modify FVS input files, add stochastic fire and drought events, and run parallel simulations from R.
