Distributions also include single-taxon modeling approaches such as habitat suitability index models or essential fish habitat models; interpretations based on empirical correlations; population change models; connectivity estimates; or evaluations of migratory pathways and spawning grounds. Assessment types include spatially applicable indices for identifying and valuing regional taxa; classifications of species (for example, as harvested, protected, or invasive) as a function of location and time; evaluations of organism condition; assessments of stressor or disturbance effects on taxa, assemblages and communities; evaluations of ecological value of species (for example, keystone species, nonredundant species); taxon-based ecological services models; and place-based indices of susceptibility and vulnerability to disturbance. Predictions include evaluations of future impacts, distributions, and ecological or economic effects due to single or multiple stressors and other projected changes, as well as scenario-testing models of taxon losses\/gains under different management options, usually combined with projections of related ecological or economic effects."

Habitat also includes biotopes in accordance with CMECS. Examples include seagrass beds, deep-water corals, benthos, nekton, plankton, mussel beds. Distributions for Habitat data subject types include records of biotic associations, habitats, or biotopes obtained through direct observation, imagery, collection, or other methods; Distributions also include biotope maps, predicted maps of present-day habitats (for example, the Northwest Atlantic Marine Ecoregional Assessment, Mapping European Seabed Habitats), and other compilations or interpretations from observed data. Assessments include ecological valuation indices, presence, quantity (hectares), or percentage of identified high-value habitats; other purpose-driven, regionally-specific indicators of ecological value; classifications of areas as critical habitat; ecological services models; evaluations of habitat condition; and place-based indices of susceptibility and vulnerability to disturbance. Predictions are the results of models or projections of future distributions, values, or impacts; anticipated changes produced by natural and human processes; future projections of cumulative impacts of single or multiple stressors; and scenario-testing habitat loss\/gain models and predictions of related ecological or economic effects under different management strategies."

Distributions are detailed topographic and bathymetric maps, geolocated photographs, or sea-floor descriptions; Distributions includes maps that interpret observations to categorize areas on the basis of geoform types such as those in CMECS. Assessment types include evaluations of ecological or human use value and can include models that project environmental or economic effects of erosion, climate change, dredging, and other stressors. Predictions are the results of models or projections of future distributions, values, or ecological impacts of physical habitats, including predicted changes due to natural and human forces; they are also from scenario-based models of resource losses, gains, or impacts on ecological or economic values under different management strategies (for example, mining, removal, relocation, or the building of structures)."

Assessments include evaluations of present ecological or economic values of substrate distributions, drivers of substrate change, and functions of substrates. Predictions are the results of models or projections of future substrate distributions, values, or ecological impacts, including predicted substrate changes due to natural and human forces including erosion, accretion, sea-level change, extraction, trawling, or other factors; and they are the results of scenario-based models of substrate changes on ecological or economic values under different management strategies or other human alterations."
