Red Maple And Red Oak Tree Lab Report

Urbanization alters the biochemical processes of the environment through the addition of excess foreign pollutants. The purpose of this experiment was to determine whether or not Red Maple and Red Oak tree species’ growth rates are negatively affected by being grown in an urbanized environment versus a rural one. The results of the ANOVA test of this experiment ANOVA test did reveal that there was correlation between the sampled habitat and the percent growth rate of tree species.
Introduction:
Urbanization is a factor that should be taken into consideration when examining the growth rates of various species. Plants that are grown in urbanized environments are typically more exposed to the pollutants that accompany them. These pollutants include CO2, NO2¬, and higher temperatures versus plants in rural areas1. Furthermore; urbanized environments have been known to affect the net primary production of plant species in a negative fashion2. The basis of the experiment revolves around the fact that urbanized environments have

Next, the tree cores were extracted and placed into a PVC pipe tube. Six Red Maple cores and three Red Oak cores were collected from Paint Creek State Park. Four Red Maple and six Red Oak cores were collected from the Greene Valley Development Center. One Red Maple core and six Red Oak cores were collected from Round Knob State park. The core samples were dried out for five days. Next the cores were placed underneath of a dissection microscope and the distance between each ring (mm) on each core was measured. The growth rates of each sample were then recorded for each sample. The summation of each consecutive measurement was recorded to construct graphs displaying the mean average growth rates for each species at each site. The following equation was used to determine growth
