Invasive alien species assessment |
extinction |
A population, species or more inclusive taxonomic group has gone extinct when all its individuals have died. A species may go extinct locally (population extinction), regionally ( extinction of all populations in a country, continent or ocean) or globally. Populations or species reduced to such low numbers that they are no longer of economic or functional importance may be said to have gone economically or functionally extinct, respectively. Species extinctions are typically not documented immediately: for example, the IUCN Red List categories and criteria require there to be no reasonable doubt that all individuals have died, before a species is formally listed as Extinct (see IUCN Red List).
|
Sustainable use assessment |
extinction debt |
The future extinction of species due to events in the past, owing to a time lag between an effect such as habitat destruction or climate change, and the subsequent disappearance of species.

extractive practice |
Extractive practices are defined as the temporary or permanent removal of organisms, part of them or materials derived from them, and may result in mortality of the individual to be used (hunting or whole plant harvest), but does not necessarily do so (e.g. limited collection of plant propagules or shearing and releasing of vicuna).

habitat fragmentation |
A general term describing the set of processes by which habitat loss results in the division of continuous habitats into a greater number of smaller patches of lesser total and isolated from each other by a matrix of dissimilar habitats. Habitat fragmentation may occur through natural processes (e.g. forest and grassland fires, flooding) and through human activities (forestry, agriculture, urbanization).

hazard |
A process, phenomenon or human activity that may cause loss of life, injury or other health impacts, property damage, social and economic disruption or environmental degradation. Hazards that this assessment discusses are mostly environmental hazards (chemical, natural and biological hazards), while cognizant that many hazards are socio- natural, in that they are associated with a combination of natural and anthropogenic factors. Natural hazards are predominantly associated with natural processes and phenomena, including geological or geophysical hazards that originate from internal earth processes (earthquakes, volcanic activities, landslides, tsunamis), and hydrometeorological hazards, which are of atmospheric, hydrological or oceanographic origin (tropical cyclones, floods, drought; heatwaves, and storm surges). Biological hazards are of organic origin or conveyed by biological vectors, including pathogenic microorganisms, toxins and bioactive substances. Examples are bacteria, viruses or parasites, as well as venomous wildlife and insects, poisonous plants and mosquitoes carrying disease-causing agents.
