R package "harvest" is a package for analyzing wildlife data and evaluating harvest-based abundance estimator performance.  The package includes three main analysis types:  Estimator Performance, Value of Information, and Decision Analysis.  In addition, any of the estimators may be used to analyze a dataset and predict the abundance of the population producing the dataset.  Estimator Performance evaluates the predictive performance of an estimator relative to the true status of a simulated population.  Value of Information compares the performance of two estimations by returning the benefit to cost rating of the two estimations.  Decision Analysis evaluates the expected performance of alternative actions providing a score for the actions relative to the objectives the actions are intended to achieve.
