A STUOV OF WINDFALL IX TIIF, ADIRONDACKS fio7 



as on the wet lowland sites where the trees would develop shallower 

 root systems. ]\Ioreover, there seemed to be a larger proportion of 

 trees broken on the drier sites while on the wetter sites the greater 

 proportion seemed to have been uprooted. 



As the hardwoods are confined to the well-drained sites and because 

 so few of them were thrown by the wind, the effect of site on the 

 damage could hardly be determined but it appeared that the damage 

 was quite uniform on all sites. 



From this study it is evident that a thinning of the character being 

 made on this tract and briefly described above does not materially 

 increase the liability to windfall. Under ordinary conditions only 

 slight damage will result and when an unusually heavy v^ind storm 

 occurs the damage is shown to be practically as much in unthinned 

 stands as in those recently thinned. Where a very heavy opening is 

 made in the stand, however, as shown in the case of the hardwood 

 type, the damage will be increased to a much greater extent. Such 

 openings either should be avoided or else the adjacent softwoods 

 should be cut much more heavily.
