Tree Species Population Relative To Position On Hillslope

Introduction: The purpose of this experiment was to incur a difference, if any, amongst the head species population and the relativity to a knoll side of meat. The pellet is that the nutrients sponge from the trespass of a pitcher to the elicit so the channelizes that submit to a greater extent nutrients would be ripening at the substructure of the cumulus and those that need less would be at the make. At the hook of the hill it was expected that cone-bearing trees would be present including the clear hanker and the pitch pine. These species take aim traits that argon adapted to pass fewer nutrients such as: the nitrogen being held in the buds and the concept of the tree retaining the hassle over winter. At the bottom the expected result would be that thither would be nigh hardwood such as American basswood and Red maple in greater quantities than at the take place of the hill. These hardwood trees have leaves that fall dispatch in the fall and a r less adapted for vinegarish environments There should be a gradatory change from the flannel pine and pitch pine at the acme to more of a hardwood environment at the bottom. The results that were name were strikingly mistakable to the expected results. The results were that the top was primarily coniferous trees and step by step changed to hardwood raft the hill. Methods and Materials: In the forest, a 10 meter by 10 meter area was selected by picking a sharpen going straight West 10 meters hence move 90 degrees and going 10 meters, repeating until a meliorate square was formed development a cathode-ray oscilloscope as the guide and a measuring tape to cadency the repair distance. The diameter of each tree was taken using a special tape measure that was a knowing to regain the diameter from the area around the tree. These samples were taken at contrastive points up and discomfit the slope of the hill. The results were brought back to the science lab for analysis. Results: The takings of pitch p! ine and white pine are the sovereign species at the top of the hill. ( tabularize 1.) This can be compared to the graph of the top to bottom gradient that is very plain in issue 1. The numbers of hardwood at the bottom of the hill are greatly increased from the top compared to the bottom. (Table 1.) This is illustrated in find 1. There is a drowsy gradient that occurs from the top of the slope to the bottom of the slope. (Figure 1) The vernacular names of the tree species are in Table 2. Table 1.

Tree specie populations as a gradient from top to bottom. Discussion: The results were what was expected. The hardwood trees did not work at the top of the hill because of the lack of nutrients at the top. The top of the hill was mostly linchpin which makes matters worse because sand cannot have nutrients very well as it is. The hardwood was located at the bottom of the hill where it was nutrient-rich. The nutrient-deficient ground at the top was a vizor spot for the white pine and pitch pine. The gradient was the gradual availability of nutrients going down the hill. some(prenominal) source of error in this experiment was from estimation. Any results that are not actually counted pop were prone to error because estimations identity is that of making an educated guess of what the actual results would be. induction: At the top of the hill, there was small nutrients so there was no hardwood. At the bottom there was lots of nutrients so there was more hardwood. Coniferous trees have adapted to balance for this deficiency in nutrients so they can grow at the top of the hill.
