New computer tools allow forecasting of populations, species, and environments through the use of simulation models, analytical models, spreadsheets, and other tools. Such models facilitate the description of situations and issues, identification of hypothesized relationships, assembly of data, the specification of assumptions, the projection of trajectories, analysis of threats, sensitivity testing of uncertainty, comparison of options, and identification of expected outcomes. This website was developed to provide information about and access to software tools that assist with species conservation assessments and planning.
