The most common indicator species are animals. [2]
A plant's indicator status is applied to the species as a whole however individual variations may exist within the species, referred to as "ecotypes"; individual plants which may have adapted to specific environments as may occur in a microhabitat, which isn't indicative of the species as a whole. The morphological differences between these ...
Indicator value is a term that is used in the ecology of plants for two different indices. The older usage of the term refers to Ellenberg's indicator values from 1974, which are based on a simple ordinal classification of plants according to the position of their realized ecological niche along an environmental gradient.

Geobotanical prospecting refers to prospecting based on the composition and health of surrounding botanical life to identify potential resource deposits. [1] Using a variety of techniques, including indicator plant identification, [2] remote sensing [3] and determining the physical and chemical condition of the botanical life in the area, [4] [5] geobotanical prospecting can be used to ...

A few lichen species are eaten by insects [16] or larger animals, such as reindeer. [60] Lichens are widely used as environmental indicators or bio-indicators. When air is very badly polluted with sulphur dioxide, there may be no lichens present; only some green algae can tolerate those conditions.

The salt marsh harvest mouse (Reithrodontomys raviventris) is also included, which is the most populated endemic mammal species in U.S. and Canadian habitats. Some hundred species of birds occur here. Indicator species are scrub jays, acorn woodpeckers, and wrentits. [5]
