In Alaska, the Alaska Natural Heritage Program, University of Alaska Anchorage (AKNHP), maintains a tracking list and rankings for the rare biota of Alaska. G#: global rank, throughout the entire range of the species S#: state rank, rarity as observed at the state level 1: species is critically imperiled due to extreme rarity (five or fewer occurrences) or due to some factor of its biology making it especially vulnerable to extinction 2: species is imperiled due to rarity (6 to 20 occurrences) or due to other factors making it very vulnerable to extinction 3: species is either very rare and local in distribution (21 to 100 occurrences) or found within a restricted range 4: species is widespread and apparently secure 5: species is clearly secure ?: a qualifier noting that the ranking is inexact; more information is needed to be certain if the rank shown is supportable Q: questionable taxonomy, the taxonomy supporting this name is questioned by some botanists S#S#: indicates rank is uncertain and best described as a range between two rankings T: indicates ranking is for the listed subspecies or variety Parker, 2006, ARCN Vascular Plant Inventory Page iii TABLE OF CONTENTS Recommended Citation ............................................... ii Keywords.......................................................... ii Abbreviations ....................................................... ii Rare Plant Ranking Abbreviations . ....................................... iii List of Figures ....................................................... .vi List of Tables ........................................................vii Abstract........................................................... .ix Executive Summary . .................................................. .xi Chapter 1: Introduction . ............................................... 1 Chapter 2: History of Early Botanical Investigations in the Arctic Network Region . 3 Chapter 3: Methods . .................................................. 5 Chapter 4: Description of ARCN Parklands and Results of I&M Vascular Plant Inventory . ............................... 7 Bering Land Bridge National Preserve. 8 Cape Krusenstern National Monument . 15 Gates of the Arctic National Park and Preserve. 25 Kobuk Valley National Park. 37 Noatak National Preserve. 44 Chapter 5: Discussion of Rare and Noteworthy Species ...................... 56 Chapter 6: Range Extensions . ......................................... 104 Chapter 7: Summary Discussion and Recommendations. 108 Acknowledgements . ................................................ 111 Literature Cited . ................................................... 112 Appendix: List of Vascular Plant Species Documented for ARCN Parklands . ..... 119 Parker, 2006, ARCN Vascular Plant Inventory Page v LIST OF FIGURES Figure 1.1.
