WebSim: simulation software to assist in trapping web design

There are many applied and theoretical reasons why estimates of population density or abundance are needed (e.g., endangered species management, effects of habitat manipulation). The trapping web is a field sampling and associated analysis method that is useful in a wide variety of biological applications. In designing a study, it is useful to have a tool to guide the sampling design. WebSim provides simulation and response surface methods to evaluate bias and precision of density estimates in a trapping web study as a function of several design variables. The software is freely available on the Internet and runs on 32-bit Windows systems.
