Reviews the silvicultural requirements of Pinus resinosa and P. strobus, and reports the results of a study to evaluate the extent to which optimum conditions for regeneration of these species (1) occurred naturally in undisturbed natural stands in the past and (2) occur after logging or destruction by fire today. A comparison is made between the occurrence of optimum conditions for regeneration of P. resinosa and P. strobus and those for P. banksiana, Populus tremuloides, Betula papyrifera and Spruce (Picea mariana and P. glauca). It is concluded that the widespread increase in distribution and frequency of Populus tremuloides, the incidence of blister rust (Cronartium ribicola) and the lack of abundant seed-trees prevent re-creation of the natural conditions formerly favourable to the establishment of Pinus resinosa and P. strobus. Data from seven areas (two burned, two logged and three undisturbed) are given in support of this conclusion.
