A glossary of definitions for terms relating to biodiversity, ecosystems services and conservation.
All definitions are referenced, where possible preference has been given to internationally recognised definitions (for example those defined by international conventions or agreements). The terms have been chosen to support understanding of biodiversity and conservation issues, and terms relating to biodiversity loss are complemented by those relating to conservation responses supported by international conservation organisations, governments, scientists and business sectors.
More detailed explanations are provided for a number of key terms, to provide further background information.
The terms can be filtered by category to aid in the navigation of the many definitions.
“The restoration of natural processes and genetic, demographic, or ecological parameters of a population or species, with regard to its state at the initiation of the recovery activities. It also refers to its past local abundance, structure and dynamics, to resume its ecological and evolutionary role, and the consequent improvement regarding habitat quality.
The Green Status assesses species against three essential facets of recovery:
A species is fully recovered if it is present in all parts of its range, even those that are no longer occupied but were occupied prior to major human impacts/disruption;
It is viable (i.e., not threatened with extinction) in all parts of the range;
It is performing its ecological functions in all parts of the range”.
