An assessment is presented of three computer packages, ALEX, RAMAS/space and VORTEX, that have been developed for analyses of metapopulation viability. Their usefulness was assessed in the context of the need to understand the assumptions and limitations of the programs. The study examined many attributes of these programs, ranging from availability and "user-friendliness" to the mathematical structure and procedures underpinning the sub-models. Key features and strengths of, and differences between, the various programs were highlighted. They are structured differently and vary in the way processes such as environmental and demographic variation are modelled. Many of these differences refle..
