Glossary for Equus przewalskii
- An arid condition is an environmental condition in which annual precipitation is less than half of annual potential evapotranspiration.
- Buffer zone
- A geographical region that serves the purpose of keeping two or more other areas (often, but not necessarily, countries) distant from one another, for whatever reason.
- Naturally formed, subterranean open area or chamber.
- Conservation status
- A region rendered barren or partially barren by environmental extremes, especially by low rainfall.
- A taxon is Endangered when the best available evidence indicates that it meets any of the criteria A to E for Endangered, and it is therefore considered to be facing a very high risk of extinction in the wild.
- This taxon is still in existence, as opposed to extinct.
- Extinction status
- Indicates whether a taxon is extant (living today) or extinct.
- First Appearance (Older Bound)
- The older bound for the first appearance of this taxon in the fossil record, in Ma.
- First Appearance (Younger Bound)
- The younger bound for the first appearance of this taxon in the fossil record, in Ma.
- The natural environment in which an organism lives, or the physical environment that surrounds (influences and is utilized by) a species population.
- Habitat. (2013, August 9). In Wikipedia, The Free Encyclopedia. Retrieved 19:01, August 14, 2013, from http://en.wikipedia.org/w/index.php?title=Habitat&oldid=567783959

- Last Appearance (Older Bound)
- The older bound for the last appearance of this taxon in the fossil record, in Ma.
- Last Appearance (Younger Bound)
- The younger bound for the last appearance of this taxon in the fossil record, in Ma.
- Million years ago
- 1 megaannum in the past. Megaannum, Ma. is a unit of time equal to one million (10^6) years.
- A wetland found in upland areas, characterised by acidic soils.
- National park
- A reserve of land, usually, but not always declared and owned by a national government, protected from most human development and pollution. National parks are a protected area of IUCN category II.
- Nature reserve
- A protected area of importance for wildlife, flora, fauna or features of geological or other special interest, which is reserved and managed for conservation and to provide special opportunities for study or research. Nature reserves may be designated by government institutions in some countries, such as the United Kingdom, or by private landowners, such as charities and research institutions, regardless of nationality.
- A region of general uniform slope, comparatively level, and of considerable extent.
- Population trend
- A grassland of the tropics or subtropics with scattered trees.
- Area covered with low-growing or stunted perennial vegetation and usually not mixed with trees.
- Shrubland biome
- A shrubland biome is a terrestrial biome which includes, across its entire spatial extent, dense groups of shrubs.
- A plain without trees (apart from those near rivers and lakes); it is similar to a prairie, although a prairie is generally considered as being dominated by tall grasses, while short grasses are said to be normal in the steppe. It may be semi-desert, or covered with grass or shrubs or both, depending on the season and latitude.
- Terrestrial habitat
- A habitat that is on or at the boundary of the surface of the Earth.
- A pond, often temporary or seasonal, used as a drinking place by mammals and birds.
- Zoological garden
