white pine
It was difficult to determine what type of pine tree this is, but it seems to fit the Eastern White Pine description fairly well, so that is what species I am treating this tree as. The Eastern White Pine is found in climates that are cool and humid and grow best in moist sandy soils. The white pine is found in mainly in Eastern North America. This tree species is monoecious and so has both male and female reproductive parts (male strobili and female flowers). From my research I found that white pines have the best seed production when the trees are 20 to 30 years old. Most white pines of this age can produce up to 75 good seeds per cone. Grey squirrels are known to aid in reproduction and dispersion by taking cones off the trees and burying them. An interesting fact about the white pine is that they are very long-lived if they are undisturbed. Some white pines have been estimated to living over 450 years.
From my observations this seems to be a single population of white pines. There are three main groups of about 4 trees of this species in my area, but they are not separated by that much space so I believe it is still one population. The nearest mating members are the other white pines that are growing near it. This species is in a clumped distribution. Two groups of the trees are located at the bottom of the hill where the water seemed to collect during our watershed activity and the other group is at the top of the hill. I believe these trees are located where they are because it seems to have the best nutrient availability at the bottom and the top of the hill. The offspring of these trees will go wherever the squirrels or other organisms take the seeds.
According to the geometric population growth equation after 5 years the population would be 50,000. After 20 years the population would be 1.52587891 × 1015. I do not think that the population is growing this way. This would be far beyond the carrying capacity for the white pine in this area. There is not enough space or nutrients for the trees to grow at this rate.
