Glossary for Salmo dentex
- Conservation status
- Data deficient
- A taxon is Data Deficient when there is inadequate information to make a direct, or indirect, assessment of its risk of extinction based on its distribution and/or population status. A taxon in this category may be well studied, and its biology well known, but appropriate data on abundance and/or distribution are lacking. Data Deficient is therefore not a category of threat. Listing of taxa in this category indicates that more information is required and acknowledges the possibility that future research will show that threatened classification is appropriate. It is important to make positive use of whatever data are available. In many cases great care should be exercised in choosing between DD and a threatened status. If the range of a taxon is suspected to be relatively circumscribed, and a considerable period of time has elapsed since the last record of the taxon, threatened status may well be justified.
- Drainage basin
- A regions or area bounded by drainage divides and occupied by a drainage system; specifically the tract of country that gathers water originating as precipitation and contributes it to a particular stream channel or system of channels, or to a lake, reservoir, or other body of water.
- A semi-enclosed coastal body of water with one or more rivers or streams flowing into it, and with a free connection to the open sea.
- This taxon is still in existence, as opposed to extinct.
- Extinction status
- Indicates whether a taxon is extant (living today) or extinct.
- Fresh water
- Freshwater habitat
- A habitat that is in or on a body of water containing low concentrations of dissolved salts and other total dissolved solids (<0.5 grams dissolved salts per litre).
- Gravel is an environmental material which is composed of pieces of rock that are at least two millimeters (2mm) in its largest dimension and no more than 75 millimeters.
- A category or description of the habitat in which the Event occurred.
- A body of water or other liquid of considerable size contained on a body of land.
- Large river biome
- Population trend
- Natural freshwater surface streams of considerable volume and a permanent or seasonal flow, moving in a definite channel toward a sea, lake, or another river; any large streams, or ones larger than brooks or creeks, such as the trunk stream and larger branches of a drainage system.
- A stream or river which flows into another river (a parent river) or body of water but which may not flow directly into the sea.
- An area that is inundated or saturated by surface or ground water at a frequency and duration sufficient to support, and that under normal circumstances do support, a prevalence of vegetation typically adapted for life in saturated soil conditions.
