J, K, L

Justification (Population Occurrence Viability Criteria): Basis for the criteria used as a basis for designating occurrence viability as excellent, good, fair, or poor, including citations if available.

Kingdom: Taxonomic Kingdom

Known Pests: Scientific names of other species (especially non-natives) where a clear detrimental impact on this species is documented.

KS: Abbreviation for the state of Kansas (United States).
KY: Abbreviation for the state of Kentucky (United States).
LA: Abbreviation for the state of Lousiana (United States).

Lacustrine Habitat(s): Value(s) that indicate(s) the lacustrine habitat(s) that contribute significantly to the survival or reproduction of the Element. Values include: deep water, shallow water, aerial.

Lagoon: Open (unvegetated), shallow, estuarine waters isolated at low tide or separated from deeper waters by a natural barrier such as a spit or barrier island.

Large Patch:Ecological Systems that form large areas of interrupted cover and typically have narrower ranges of ecological tolerances than matrix types. Individual disturbance events tend to occupy patches that can encompass a large proportion of the overall occurrence (e.g. >20%). Given common disturbance dynamics, these types may tend to shift somewhat in location within large landscapes over time spans of several hundred years. In undisturbed conditions, typical occurrences range from 50-2,000 ha.
LB: Abbreviation for Labrador, which makes up part of the province of Newfoundland and Labrador (Canada).
Length: For animals only: Approximate typical total length of an adult, in centimeters. Carapace length used for turtles and snout to vent length for anurans (frogs and toads).
Linear:Ecological systems that occur as linear strips and are often ecotonal between terrestrial and aquatic ecosystems. In undisturbed conditions, typical occurrences range in linear distance from 0.5 to 100 km.

Locally Migrant: Data provided in species reports. Indicates this species makes local extended movements (generally less than 200 km) at particular times of the year (e.g., to breeding or wintering grounds, to hibernation sites).

Long Distance Migrant: Data provided in species reports. Indicates populations make annual migrations of over 200 km.

Long Term Trend: A code that best describes the degree of past directional change in population size (for species only), extent of occurrence, area of occupancy, number of occurrences, and/or viability or ecological integrity of occurrences over the long term (ca. 200 years). For more information see NatureServe Conservation Status.

Long Term Trend Comments: Comments on long-term trends of a species or ecological community.

Low Gradient: Streams with a fall less than 0.2 meters per kilometer; there may be sand bars, but the sediments are mostly silt.
