TREE RANGES VERSUS LIFE ZONES IN NEW YORK STATE 



In concluding the discussion of the zonal distribution of vegeta- 

 tion in New York State and the distribution of trees within the 

 State, it would be desirable to plot the range of each species upon 

 a map of the State. This cannot be done, however, at the present 

 time owing to a dearth of sufficient data covering areal develop- 

 ment of the various trees within our borders. Particularly is this 

 true in the case of naturalized forms which are still undergoing 

 expansion and whose future range is yet more or less prob- 

 lematical. Under the circumstances it has seemed best to indicate 

 the zonal distribution of each species by letter and to insert this 

 information in the descriptive data accompanying each plate under 

 "Range". Blackfaced type indicates relative abundance within 

 the zone concerned, although not of necessity that the form is an 

 indicator species.
