Ecological community is defined broadly here, but includes both ecological interactions (inherited from parent term community) and spatial co-existence. It may be used to describe every organisms living in an area, but is often used to refer only to organisms of a particular taxon or guild (e.g., the plant community, the insect community, the herbivore community). The word community, as it often used to describe a group of humans living together, is a type of single-species collection of organisms, not an ecological community.

multispecies community

A community of at least two different species, living in a particular area. Must have at least two populations of different species as members.
