CATEGORIES OF ECOLOGICAL MODELS

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.
