APPENDIX Q: VEGETATION IN THE PLANNING AREA AS 

OF FALL 2007 

Table Q- 1 displays the vegetation composition of the planning area by vegetation community and 

vegetation sub-group (VSG) following the 2007 wildland fire season. Vegetation composition is presented 

by Vegetation Management Area (VMA) as well as for the planning area as a whole.
