Table A-2 — Key to the Vegetation Element of the Land Classification Framework- 

 Class: Woodland 1 



Class: Woodland 



Subclass 



Group 



Formation 



Open forest (trees over 5 m 

 tall forming 26 to 60 per- 

 cent canopy cover 



Mainly evergreen woodland 

 (canopy never without 

 green foliage although 

 some trees may shed their 

 leaves.) 



Mainly deciduous woodland 

 (majority of trees shed fo- 

 liage as result of drought 

 or cold) 



Evergreen broad-leaved 

 woodland 



2. Evergreen needle-leaved 

 woodland 



1. Tropical and subtropical 

 drought-deciduous wood- 

 land (frost and freeze gen- 

 erally absent or moderate) 



2. Cold-deciduous woodland, 

 with evergreen trees (winter 

 frost and freeze) 



(No formations defined; in- 

 cludes evergreen oak wood- 

 lands) 



a. Evergreen needle-leaved 



woodland with rounded 

 crowns (e.g., pine and 

 juniper) 



b. Evergreen needle-leaved 



woodland with conical 

 crowns (e.g., spruce in the 

 west) 



c. Evergreen needle-leaved 



woodland with very narrow 

 cylindro-conical crowns 

 (e.g., some spruce in 

 Alaska) 



a. Drought-deciduous broad- 



leaved lowland and sub- 

 montane woodland 



b. Drought-deciduous montane 



(and cloud) woodland 



a. Evergreen broad-leaved 



woodland 



b. Evergreen needle-leaved 



woodland 



Cold-deciduous woodland, 

 without evergreen trees 

 (winter frost and freeze) 



C. Extremely xeromorphic 1. Sclerophyllous woodland 



woodland (dry woodlands) 



a. Broad-leaved deciduous 



woodland 



b. Needle-leaved deciduous 



woodland 



c. Mixed deciduous woodland 



(broad-leaved and needle- 

 leaved) 



a. Evergreen sclerophyllous- 

 dominated xeromorphic 

 woodland 



2. Thorn-woodland (may not be 

 represented in U.S.) 



a. Mixed deciduous-evergreen 



thorn woodland 



b. Purely deciduous thorn 



woodland 



3. Mainly succulent woodland 



1 The key to the vegetation element is patterned after UNESCO 1973. The key contains a few examples of known communities in the 

 United States.
