Metapopulation modeling system for population viability analysis and extinction risk assessment.


RAMAS Metapop is an interactive program that allows you to build models for species that live in multiple patches. It incorporates the spatial aspects of metapopulation dynamics, such as the configuration of the populations, dispersal and recolonization among patches and similarity of environmental patterns experienced by the populations. The program can be used to predict extinction risks and explore management options such as reserve design, translocations and reintroductions, and to assess human impact on fragmented populations.

Description Of System Components

RAMAS Metapop: core metapopulation model for population viability analysis and extinction risk assessmentRAMAS GIS: links Metapop to your GIS dataRAMAS Landscape: integrates the landscape model LANDIS with the habitat-based metapopulation model RAMAS GIS. With the integration of a landscape and a metapopulation model, predictions about the viability, recovery, and growth of species can be based on the predicted changes in the landscapes in which they live.RAMAS Multispecies Assessment: calculates site values based on the importance of and the magnitude of the threats facing the component species.
