Global <strong>and</strong> local plant community descriptions<br />
C.1 Introduction<br />
The plant community descriptions present information on each association, alliance, <strong>and</strong><br />
park special as it occurs in Petrified Forest NP (local) <strong>and</strong> as it has been found elsewhere<br />
(global) (NatureServe 2007). The plant communities are organized by life form–woodl<strong>and</strong>,<br />
shrubl<strong>and</strong>, herbaceous, <strong>and</strong> finally sparse.<br />
Following is a summary of the information provided by each description, in the order in<br />
which it occurs within each description:<br />
1. Scientific name for plant community<br />
o. Translated name for plant community assigned by NatureServe<br />
o. NatureServe Code: Community Element Global code (CEGL) assigned by<br />
NatureServe<br />
2. Summary: Global concept of plant community<br />
3. <strong>Classification</strong><br />
o. <strong>Classification</strong> Confidence: The level of confidence in the classification, based<br />
on the quality <strong>and</strong> type of data used in the analysis, as well as the extent to<br />
which the entire (or potential) range of the element was considered. Values<br />
include: 1 = Strong, 2 = Moderate, <strong>and</strong> 3 = Weak.<br />
o. <strong>Classification</strong> Comments: Globally <strong>and</strong> locally<br />
o. <strong>Vegetation</strong> Hierarchy<br />
- Physiognomic Class: NVCS version 1 class<br />
- Physiognomic Subclass: NVCS version 1 subclass<br />
- Physiognomic Group: NVSC version 1 group<br />
- Physiognomic Subgroup: NVCS version 1 subgroup<br />
- Formation Name: NVCS version 1 formation name<br />
- Alliance Name: NVCS version 1 alliance name<br />
4. Ecological Systems Placement: Nature Serve-assigned ecological system<br />
5. NatureServe Conservation Status: NatureServe-assigned conservation status rank<br />
(G5 Secure/G4 Apparently secure/G3 Vulnerable/G2 Imperiled/GNR Not yet<br />
ranked)<br />
6. Distribution: Global <strong>and</strong> local distribution<br />
7. Environmental Setting<br />
o. USFWS Wetl<strong>and</strong> System (Cowardin et al. 1979)<br />
o. Global <strong>and</strong> local environments of occurrence<br />
8. <strong>Vegetation</strong><br />
o. Global <strong>and</strong> local descriptions<br />
o. Most Abundant Species: Global <strong>and</strong> local<br />
o. Other Noteworthy Species: Global <strong>and</strong> local<br />
9. Element Sources<br />
o. Authors of global <strong>and</strong> local descriptions<br />
o. References<br />
