Pinus contorta latifolia
Name: D'Arcy H.
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.
