Landscape Models
Landscape models are useful for evaluating the impact of changes to features (e.g., fragmentation, edge-area ratios> of large areas on habitat and populations of species or communities of concern.
Metapopulation Models
Species that occur in disconnected patches having independent dynamics within each patch but connected by dispersal, may behave as a metapopulation.
Population Models
Population demographic models provide a means of determining the viability of populations at a single installation and of evaluating impacts of changes in habitat on those populations.
Habitat Models
GIS-based habitat models utilize existing spatial data layers (e.g., land cover, soils, geology, topography) to predict the location and extent of habitat for species and communities of concern.
