A Field Guide to the Special Status Plants of Grand Canyon National Park

Brian, Nancy

This guide includes 63 plant species that have Federal listing, candidate status, or are considered rare, endemic, or new to science. It is arranged in a 3-ring binder to make it easy to add or subtract pages as new information warrants changes. Single sheets can be removed for field use. If you know ahead of time that you will encounter a specific habitat, soil type, or feature described by a place name, those species listed alphabetically by these characteristics can be removed and taken into the field. The plants covered in this guide are arranged alphabetically by genus. A code written in the upper right hand corner of each sheet identifies whether the plants are Federally Protected Plants (Endangered Species and Species of Special Concern), Category 3b and 3c, or rare. Some plants have no illustration or photographs available at this time. When these items become available, replacement sheets can be inserted. At present, no threatened, Category I, or Category 3a plants are known to occur in Grand Canyon National Park. Definitions of these codes are given in "Codes, Definitions, and Abbreviations."
