The general conclusions outlined above may be summarized as follows: 



1. White pine grows typically in even-aged stands in which all the trees, 

 both large and small, are of approximately the same age. 



2. Trees of small size may be the result not only of lack of age, but of poor 

 growing conditions or of crowding by other trees. A small average scale may 

 be caused by an excessive amount of rot in logs even though the logs come from 

 fairly large trees. 



3. For the purpose of preventing the cutting of timber that is too young or 

 too small, a general regulation limiting either the age or the size of the timber 

 that may be cut will not give satisfactory results. An inspection of each ques- 

 tionable area by a trained official is desirable in order that a decision may be 

 made in each case on the basis of the actual conditions, 



4. Many very extensive areas of young growth, including much valuable 

 young pine, ranging in age from twenty-five to eighty years of age, are to be found 

 in the timbered portion of the Province. This young growth came up after fires 

 that burned through virgin timber. 



5. The conditions following the fires of the past twenty-five years will not 

 be as favourable as on the areas burned over at earlier times since these later fires 

 burned over more young growth and logged-off areas. 



6. The second-growth stands contain a large proportion of poplar which 

 investigation shows to die out at a comparatively early age, leaving the pine to 

 form the mature stand. These stands, therefore, will produce more pine timber 

 than their present condition would indicate superficially. 



7. Detailed studies must be made of the growth of pine and poplar in mixture 

 as well as of pine in pure stands, to make it possible to properly appraise the 

 present and future value of young second-growth stands.
