f <br />Table lA. Definition of Natural Heritage Global Rarity Ranks <br />1 These ranks should not be interpreted as le;al designations. <br />j Global hank (G): Based on the range-wide status of a species. <br />1 G 1 Critically imperiled globally because of exveme rarity (5 or fewer <br />occurences, or very few remaining individuals), or because of some factor of <br />iu biology making it especially vulnerable to extinction. <br />G2 Imperiled globally beca~~se of rarity (6 to 20 occurrences), or because <br />of other factors demonsvably making it very vulnerable to extinction <br />throughout iu range. <br />G3 Vulnerable throughout iu range or found locally in a resvicted range <br />(21 to 100 occurrences). <br />G4 Apparently secure globally, though it might be quite rare in pare of <br />iu range, especially at the periphery. <br />G5 Demonstrably secure globally, thou;h it may be quite rare in parts of <br />iu range, especially at the periphery. <br />GX Presumed extinct. <br />G~? Indicates uncertainty about an assigned global rank. <br />GU Unable to assign rank due to lack of available information. <br />GQ Indicates uncertainty about taxonomic status. <br />G#T# Trinomial rank (T) is used for subspecies or varieties. These taxa are <br />ranked on the same criteria as G1-G5. <br />7 <br />
