VA: Abbreviation for the state of Virginia (United States).

Vegetation Summary: Summary description of the characteristic leaf type and phenology, species composition, structure and variability of vegetation.

Vegetation Variability
Range of variability in structure and species composition among occurrences of this community.

Vertebrate: For more information see Classification of Vertebrates and Invertebrates.

Viability/Integrity Comments: Specific details on the number of occurrences with good viability or ecological integrity or additional information on those with fair or poor viability or ecological integrity.

VT: Abbreviation for the state of Vermont (United States).
WA: Abbreviation for the state of Washington (United States).

Watershed Code: The 8-digit code (HUC-8) from the US Geological Survey Hydrologic Unit Map for each watershed where the species is located. For more information on US Geological Survey Hydrologic Unit Maps see http://water.usgs.gov/GIS/huc.html

Watershed Name: The name corresponding to the US Geological Survey Hydrologic Unit for each watershed where the species is located. For more information on US Geological Survey Hydrologic Unit Maps see http://water.usgs.gov/GIS/huc.html

Watershed Region: The 2-digit code (HUC-2) from the US Geological Survey Hydrologic Unit Map for each region where the species is located. Regions are the first level of classification of US Geological Survey Hydrologic Units which divides the Nation into 21 major geographic areas, or regions. The first two digits of the watershed code (HUC-8 code) specify the region. For more information on US Geological Survey Hydrologic Unit Maps including a map of the watershed regions see http://water.usgs.gov/GIS/huc.html

Weight: Data provided in species reports. Approximate weight of an adult in grams.
Wetland: Wetland ecological systems were defined following a non-regulatory definition for wetlands, emphasizing three important attributes: (1) the hydrology is such that there is some degree of flooding or soil saturation; (2) the vegetation is composed of plants adapted to grow in water or in a soil or substrate that is occasionally oxygen deficient due to saturation (hydrophytes); and (3) the soils are those saturated long enough during the growing season to produce oxygen-deficient conditions in the upper part of the soil, which commonly includes the major part of the root zone of plants (hydric soils).

Wetland Indicator: Defines whether or not this is a wetland or an upland Level 5 unit (Formation).

WI: Abbreviation for the state of Wisconsin (United States).
WV: Abbreviation for the state of West Virginia (United States).
WY: Abbreviation for the state of Wyoming (United States).
YT: Abbreviation for the Yukon Territory (Canada).
