Some Problems in Maintaining an Adequate Seed Supply for a Provincial Reforestation Problem
Every nurseryman and tree planter is constantly haunted by a horrible picutre - the vision of an empty seed store. In British Columbia we have been faced with this prospect perhaps oftener than most organizations represented here today. Although operating near the northern extremity of the range of coastal Douglas-fir, we found good cone crops at low elevations occurred frequently enough. However, as the planters followed the stump line up the hills to the top elevation range of this species we found that cone crops here were a rare occurrence. Time and time again a good cone crop would fade out at eleven to thirteen hundred feet and we would be left with the stopgap alternative of using seed collected farther north. (We try as much as possible to follow Leo Isaac's suggested rules (2) for Douglas-fir seed but will stretch the elevation limit of planting stock to 1,000 feet above seed source if necessary).
