Best development in southern Al-

Mainly Northeastern United 

 States; extends farthest west 

 and northwest oi any of the 

 Eastern oaks. 



East of the Rocky Mountains 



Well drained, rich soils. 

 Shade enduring. 

 Poliaue evergreen. 



For planting on rocky banks and hillsides; never in any but 

 well drained situations. 



Requires better soil than White Oak— deep, rich loam; more 



shade-enduring 



Southeastern United States 



Best developed in Arkansas and 

 adjacent Texas. 



A Western substitute for White Oak, and especially recom- 

 mended for prairie planting. 



Well-drained gravelly uplands, clay barrens, and poor sandy 



loams. 

 Recommended for Western planting. 



Northeastern United States 



(Quercus platanaides (Lam.) 

 Sudw.) 



Height, 90 feet + ; diameter, 

 2 teet-f .

 Sudw.) 



Height, 80 feet-f ; diameter, 

 3 teet-j-. 



Best development in region south 

 of the Great Lakes. 



Chiefly in wot or submerged swamps, but grows well in well- 

 drained bottom lands and on rich, gravelly, or sandy loam 

 uplands. 



In deep moist or inundated swamps and low banks of water 

 courses. Succeeds in all loose, rich, fairly moist upland soils.

East of longitude 96°, United 



States. 



Best development in North At- 

 lantic States. 



Central, Southeastern, and South- 

 ern States. 



Best development in South At- 

 lantic and Gull States. 



Central, Southern, and Southeast 



em States. 



Greatest development in eastern 

 Gulf region. 



Thrives in all soils, except an undrained one. 



The most rapid in growth of all the oaks. Sprouts vigorously 

 trom stump ; of importance for tan-bark coppices. 



Gravelly uplands ; poorer soils than White Oak requires. 

 Next to the Red Oak in rapidity of growth. 



Dry, barren soils ; rapid grower. 



Heavy undrained soil ; exceedingly rapid grower. 

 A useful concomitant in Southern planting.
