The wetland status of 7,000 plants is determined upon information contained in a list compiled in the National Wetland Inventory undertaken by the U.S. Fish and Wildlife Service and developed in cooperation with a federal inter-agency review panel (Reed, 1988). The National List was compiled in 1988 with subsequent revisions in 1996 and 1998.
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.

A biological indicator is also the name given to a process for assessing the sterility of an environment through the use of resistant microorganism strains (e.g. Bacillus or Geobacillus). [5] Biological indicators can be described as the introduction of a highly resistant microorganisms to a given environment before sterilization , tests are ...
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 ...

When compiled, local indicators may be too diverse to provide a national result. Indicators also face other limitations and challenges, such as: Lack of reference levels, therefore it is unknown if trends in environmental change are strong or weak. Indicator measures can overlap, causing over estimation of single parameters.
It does this in line with the CBD 2010 indicator for species abundance. [10] The Biodiversity Intactness Index (BII) measures biodiversity change using abundance data on plants, fungi and animals worldwide. The BII shows how local terrestrial biodiversity responds to human pressures such as land use change and intensification. [11]
