Question:
I am a Silviculturist for West Fraser Mills in British Columbia, and we are looking at using more natural regeneration or direct seeding for our Lodgepole Pine(Pinus contorta latifolia) managed stands. My question is this, is there any research on the degree days or heat sum requirements for seed germination of this species? Our hopes are to monitor weather patterns so that we can say with some confidence that the weather incurred over the growing season was or was not conducive to good seed germination. If the weather did meet the desired temperatures and moisture than we will wait and monitor the regeneration, if we have a number of years that are cool and wet, then we had better look at establishing planted stock on the sites.
