833 Words4 Pages

Trees rings are rings within the trunk of the tree. A method that scientist use to analysis the pattern of the growth of a tree is known as Dendrochronology. The way that tree rings are produced, is during growth season the trunk grows thicker that produces a new layer of wood (United States Environmental Protection Agency). Paleoclimatologist use tree-rings to analysis the climate changes and the health of the forest or the environment around it. Each of the rings is consist with a year of growth and tell scientist how long the tree has been around. Scientist determines if the tree had a good growth rate by looking at the thickness of the rings. If the ring is thin then there that most likely means that there wasn’t a lot of growth, which means that it could be a number of things that prevent the growth of the tree such as not a lot of precipitation, or just simply a period of droughts. Trees have many basic patterns of growth such as in conifers reproductive cambium cells form large, thin-walled earlywood tracheid during primarily serve …show more content…

It is known as the segment length curse, which makes it hard to use the tree-ring to determine age (McCarroll and Loader). Using tree-rings to look at the history of the climate is pretty difficult because there could be many misinterpretations with tree-rings. One thing that has to be taken into consideration when observing tree-rings is the impact that carbon dioxide might have on the growth of the tree. The second thing scientist have to take into consideration when interpreting is the method of tree-ring standardization. It is a statistical procedure that may inadvertently bias the resulting temperature interpretations, either positively or negatively, if done incorrectly

tall. The circumference determines the size and can be used to determine the diameter which can be used to determine the age of the tree through secondary growth. These measurements can be used to compare the correlation between age and size of a tree since the oldest tree should have a larger diameter in comparison with a smaller tree, therefore if the age of a tree is higher than the diameter of a tree should be larger and vice versa. The result collected is only a portion of the large forest therefore the data pool is not large enough to support the hypothesis. The experiment will help answer if the upslope and downslope forest are off different

To test the hypothesis that mistletoe abundance effects tree health and diameter, we quantified the number of trees that did and did not possessed the Big Leaf Mistletoe along a 50m plot from the perennial river edge. We did this by evaluating each tree we saw by eye, looking for signs of mistletoe on the tree. We them recorded the diameter of the trees and a quantified scale of health for the trees between one and three; three being good health and one being low health. We also recorded the number of different growths of Big Leaf Mistletoe on the trees that possessed mistletoe. We did this for the first 50 trees we came into contact with, within our 50 m perimeter from the river.

The Black Walnut Tree Analysis

641 Words | 3 Pages

The Black Walnut Tree In Mary Oliver’s “The Black Walnut Tree,” Oliver employs personification, split section, and conflict between literal and figurative to establish the tree’s role in the family as a symbol of both the adversities and the rewards that arise from their endeavor to preserve their family history. The personification of “black walnut tree swing through another year of sun” is used to convey the fresh and renewed spirit of the family once they decide to keep their family together. The idea of the tree “swinging” represents a cheerful spirit. Since the author chooses to embody this cheerful spirit in her writing, it demonstrates the idea of family and home; money tends to draw people apart, but happiness and favor comes with the idea of an object like the walnut tree that forges the relationship in a family.

This water replenishes clouds and maintains rainfall.
