The decline of the white pine area is evident. This corresponds 

 with the situation in other countries (Beversluis, 1938; MacDonald et al. 3 

 1957; Misson, 1962). In opposition to this are announcements of increased 

 plantings in the Netherlands and Czechoslovakia (Gremmen, 1966; Holubcik, 

 1968a), plus my personal observations in Hesse, and other information 

 from research workers of several European countries, for which I am 

 indebted. 



Considering these facts, my estimate is that the present (or at 

 least recent) area of P. strobus in Europe may in fact be as great as 

 shown in Table 2.
