A variety of objective means exist to empirically measure biodiversity. Each measure relates to a particular use of the data, and is likely to be associated with the variety of genes. Biodiversity is commonly measured in terms of taxonomic richness of a geographic area over a time interval. In order to calculate biodiversity, species evenness ...
The book introduced the Endemic Bird Area (EBA) concept and argued for its use as a means of identifying important areas for the conservation of all biodiversity worldwide. The book starts with a number of sections outlining its overall aim, scope and methods.
forest areas containing globally, regionally or nationally significant: concentrations of biodiversity values (e.g. endemism, endangered species, refugia); and/or large landscape-level forests, contained within, or containing the management unit, where viable populations of most if not all naturally occurring species exist in natural patterns ...
An OECM is defined by the Convention on Biological Diversity as: [A] geographically defined area other than a Protected Area, which is governed and managed in ways that achieve positive and sustained long-term outcomes for the in situ conservation of biodiversity, with associated ecosystem functions and services and where applicable, cultural, spiritual, socio–economic, and other locally ...
Key Biodiversity Areas (KBA) are geographical regions that have been determined to be of international importance in terms of biodiversity conservation, using globally standardized criteria published by the IUCN as part of a collaboration between scientists, conservation groups, and government bodies across the world.

Essential Biodiversity Variables (EBVs) is a putative set of parameters intended to be the minimum set of broadly agreed upon necessary and sufficient biodiversity variables for at least national to global monitoring, researching, and forecasting of biodiversity. [1]
Biodiversity banking places a monetary value on biodiversity. One example is the Australian Native Vegetation Management Framework. Gene banks are collections of specimens and genetic material. Some banks intend to reintroduce banked species to the ecosystem (e.g., via tree nurseries). [217]
The index is easy to interpret: NDVI will be a value between -1 and 1. An area with nothing growing in it will have an NDVI of zero. NDVI will increase in proportion to vegetation growth. An area with dense, healthy vegetation will have an NDVI of one. NDVI values less than 0 suggest a lack of dry land. An ocean will yield an NDVI of -1
