Taxonomic Comments: Pertinent information regarding questions or controversies concerning the validity, taxonomic distinctness, or generic placement of the plant or animal species. May also provide information about the scientific name or its spelling. May include discussion of differing taxonomic or nomenclatural usage by other conservation agencies and organizations. Note: Plants discussion may be incomplete. For more information please see Classification Sources.

Taxonomic Serial Number (TSN): The unique identifier for a taxonomic unit assigned by the Integrated Taxonomic Information System (ITIS)

Technical Description: A technical scientific description of the species similar to those found in technical botanical works.

Temporary Pool: Small depressions in which surface water is present for extended periods (especially early in the growing season) but is absent by the end of the season in most years; "seasonally flooded" (Cowardin).

Terrestrial Habitat(s): Terrestrial habitat(s) where the species is found: Values include: forest-hardwood, forest-conifer, forest-mixed, woodland-hardwood, woodland-conifer, woodland-mixed, shrubland/chaparral, savanna, grassland/herbaceous, old field, desert, alpine, tundra, ice, playa/salt flat, sand/dune, bare rock/talus/scree, cliff, cropland/hedgerow, suburban/orchard, urban/edificarian, aerial.

The Nature Conservancy's Conservation Ecoregion Code: Codes of The Nature Conservancy's Conservation Ecoregion.

The Nature Conservancy's Conservation Ecoregion Name: Name of The Nature Conservancy's Conservation Ecogregion

The Nature Conservancy's Conservation Ecoregions Occurrence Status: The degree of certainty that the Association or Ecological System occurs in a particular Conservation Ecoregion of The Nature Conservancy. Values include: C = Confident or Certain, P = Predicted or Probable, ? = Possible, X = Presumed Extirpated, [] = Data Entry Incomplete.

Threat Immediacy: : For the threat with the greatest overall impact on the species, the imminence of the threat to the species (i.e., how likely the threat to the species is and how soon it is expected to be realized) from a range-wide perspective. Values include: High = Threat is operational (happening now) or imminent (within a year), Moderate = Threat is likely to be operational within 2-5 years, Low = Threat is likely to be operational within 5-20 years, Insignificant = Threat not likely to be operational within 20 years Unknown = Unknown (how soon the threat will likely be realized is unknown).

Threat Scope: For the threat with the greatest overall impact on the species, the proportion of the species that is observed, inferred, or suspected to be directly or indirectly affected by this threat from a range-wide perspective. Values include: High = > 60% of total population, occurrences, or area affected, Moderate = 20-60% of total population, occurrences, or area affected, Low = 5-20% of total population, occurrences, or area affected, Insignificant = < 5% of total population, occurrences, or area affectedUnknown = Unknown (proportion of population, occurrences, or area affected is unknown).

Threat Severity: For the threat with the greatest overall impact on the species, how badly and irreversibly the species is observed, inferred, or suspected to be directly or indirectly affected by the threat from a range-wide perspective. Values include: High = Loss of species population (all individuals) or destruction of species habitat or ecological community in area affected, with effects essentially irreversible or requiring long-term recovery (>100 years), Moderate = Major reduction of species population or long-term degradation or reduction of species habitat or ecological community in area affected, requiring 50-100 years for recovery, Low = Low but nontrivial reduction of species population or reversible degradation or reduction of species habitat or ecological community in area affected, with recovery expected in 10-50 years, Insignificant = Essentially no reduction of species population or degradation of species habitat, ecological community or System due to threats, with ability to recover quickly (within 10 years) from minor temporary loss, Unknown = Unknown (degree of impact on population, occurrences, or area due to threat is unknown).

Threats: Description of known global threats to the species.

Tidal Flat/ Shore: Non-vegetated zone of wave or tidal action, intermittently exposed or inundated.

Translated Alliance Name: The translated name for the Alliance based on the common names of the nominal plant species. Note: Translated names may not be available for all Alliances. A standard list of common names has been developed by NatureServe Ecology for use in translated names. For more information see Classification of Ecological Communities.

Translated Name: The translated name for the Association based on the common names of the nominal plant species. A standard list of common names has been developed by NatureServe Ecology for use in translated names. For more information see Classification of Ecological Communities.

TSN: See Taxonomic Serial Number.

Tundra: Herbaceous and dwarf shrubby vegetation beyond the subpolar tree line.
