Realized niche width is a phrase relating to ecology, is defined by the actual space that an organism inhabits and the resources it can access as a result of limiting pressures from other species (e.g. superior competitors).

The parameters of a realized niche are described by the realized niche width of that species. [26] Some plants and animals, called specialists , need specific habitats and surroundings to survive, such as the spotted owl , which lives specifically in old growth forests.
Species distribution modelling (SDM), also known as environmental (or ecological) niche modelling (ENM), habitat modelling, predictive habitat distribution modelling, and range mapping [1] uses ecological models to predict the distribution of a species across geographic space and time using environmental data. The environmental data are most ...
The effect on realized niches could be incredibly strong, especially when there is an absence of more traditional interference or exploitative competition. A real-world example was studied in the late 1960s, when the introduction of snowshoe hares (Lepus americanus) to Newfoundland reduced the habitat range of native arctic hares (Lepus arcticus).
The realized niche is the set of environmental plus ecological conditions under which a species persists. [ 30 ] [ 32 ] [ 33 ] The Hutchinsonian niche is defined more technically as a " Euclidean hyperspace whose dimensions are defined as environmental variables and whose size is a function of the number of values that the environmental values ...
