Appendix A: 



Keys to the Upper Four Levels 



of the Vegetation Element 



The tables in this appendix identify and define the upper 

 four levels of the vegetation element of the national land 

 classification framework — classes, subclasses, groups, 

 and formations. To provide field users quick access to 

 information they need to classify land, the five classes — 

 forest, woodland, shrubland, dwarf-shrubland, and her- 

 baceous vegetation — are treated on five separate tables. 

 No national key for the lower categories — series and 



associations — has yet been developed. Some of this infor- 

 mation, however, is available locally in many areas of the 

 country from the agencies that cooperated on this report. 

 The information presented in the tables relies heavily 

 on The United Nations Educational, Scientific and Cul- 

 tural Organization's International Classification and 

 Mapping of Vegetation, Series 6, Ecology and Conserva- 

 tion published in 1973.
