title: Canopy Cover and Diameter at Breast Height of Adult and Sapling Trees at York University

description: A field study was conducted examining tree trunk diameter, corresponding canopy coverage, and location of same species saplings. <br>Methods:<br>- Experimenters performed the study in woodlands at York University- Two 25m Transect tape rollers were used to mark 50m of woodland- Students proceeded along Transect tape and located mature trees, approximately 3.5m or taller. - Mature tree diameter at breast height (approximately 1.5m) was recorded; as well as canopy coverage, as a percentage. - Saplings of the same species were then located, and distance from adult along with diameter at breast height (DBH) were recorded. - The process was carried out for 50m of woodland totalling to 10 adult trees. <br>Hypothesis:<br>There will be a correlation between the distance a sapling is from an adult tree and the diameter at breast height (DBH) of the adult tree.<br>Prediction:<br>There will be a larger distance between the sapling and an adult as the DBH of the adult increases. As DBH increases so does the height of the tree, allowing for a wider distribution of seeds causing saplings to be at greater distances from the adult. <br>Metadata:<br>- Diameter at Breast Height: A numerical, quantitative measure of the diameter of a tree at approximately 1.5m above the ground, recorded in metres. - Canopy Coverage: Quantitative and numerical data. Approximate canopy coverage as a percentage was recorded using hands to estimate. - Distance of Same Species Sapling: A numerical, quantitative observation recording the distance in metres from the adult tree to the closest sapling of the same species. <br><br><br>

title: Ecology Lab 2 Grassland Dataset (Pond distance vs vegetation percentage)

description: This ecological experiment which was done at York University grasslands, Monday, September 20/2016, at 2:30 P.M, Studies the relationship between the vegetation percentage (ratio of plant individuals to grass) and the distance from the pond. The study was done using a 1meterx1meter square quadrat which was randomly thrown 25 times. <b>Methods</b> A 1meterx1meter square quadrat was used for this experiment. The quadrat was randomly thrown 25 times (n=25 trials) in the grasslands beside the pond and the total number of plant individuals, number of plant species, vegetation percentage, and grass percentage in the quadrat box were counted, calculated and recorded on a piece of paper. The data was then transformed into an excel sheet and uploaded on “FIgshare.com”. <b>Hypothesis</b> There is a correlation between the distance the individuals are from the pond and the percentage vegetation (vegetation density).<br> <b>Prediction</b> The quadrats that were randomly thrown closer to the pond will have a higher vegetation percentage than the ones thrown further away from the pond.<br> <b>Meta-data</b><b> </b> Trial number: the number of trials that the quadrat was randomly thrown to collect the data which was 25 times therefore n=25 trials. Canadian Goldenrod (yellow) Heath Ester (white), Butter and Eggs, Common Thistle (thorn), Late Purple Aster, small tree: Plants species found in York Universities grassland fields. Please refer to a plant atlas for more information about these plant species. Number of plant species: The different types of plant species that were seen in the quadrat box. Total number of plant individuals: The total number of plants in the square quadrat were counted. This included all species of plants in general and included any type of plant. i.e. how many plants in general in the box. Vegetation percentage (vegetation density): The percentage of plants compared to grass in the square quadrat. In other words, the ratio of plants to grass in the quadrat. Grass percentage (grass density): The percentage of grass compared to plants in the square quadrat. In other words, the ratio of grass to plants in the quadrat.

title: York University Woodlot Data

description: The purpose of this study is to observe abundance of the plant species of an area in relation to its canopy and girth specifically near the Osgoode woodlots.<b>Methods:</b>Transect tape was used to gather data in one area of the woodlot. The point-intercept method was used as a sampling method where the transect tape was laid across on one area of the woodlot and record what plant species in front of the tape. Along the transect line, the distance between target tree and the nearby tree was also measured. For the canopy coverage, we used our hands, form it like a square and use it as a tool to measure how much coverage the outer layer of trees covered. <b>Hypothesis: </b> There is a correlation between density of the tree population and the extent of the canopy coverage and its diameter of breast height (dbh).<b>Prediction:</b> There is a correlation between the density of trees of a particular area to its canopy coverage and its dbh. Increase density of the trees will lead to decrease in coverage and its dbh because of the competition between the trees for sustenance and sunlight, which lead to scarcity of resources. Thus, a thinner appearance of the trees and more sunlight peeking through the ground.<br><b>Metadata:</b>· <b>Distance:</b> Metres was used for measuring the distance between two nearby adult trees with the area of study. 25 metres of transect tape was covered around the area of study.· <b>Trees:</b> 10 Adult trees were selected. That adult trees were chosen based on the twice the height of the observer. The observer’s height was 5 feet 4 inches, thus the approximate height of the adult tree would be 10 feet. The trees are randomly selected and not in the same species.· <b>Dbh:</b> Diameter breast height, the measuring of the girth of the tree. It is measured by using the height of the observer’s torso as a mark to measure the circumference of the tree. It was originally measured using the transect tape, which measures in feet but was converted into metres. · <b>Canopy coverage</b>: The coverage of the leaves provided located in the upper layer of the trees. Basically, how much coverage it provides that would mask the sky. It is ranked by percentage, 0% being no coverage while 100% being the most coverage.<br>· <br>

description: The purpose of this lab was to identify and compare the coverage in percentage of grass versus plants in each quadrat of the grassland. The data of this experiment was collected from the grassland lot located at York University Keele Campus (43.7 degrees North, 75.9 degrees West), between York Blvd and Keele St. at 3:00pm. It was 26°C outdoors in the grassland lot and very sunny. The quadrat was randomly placed on the ground in the grassland lot, and the total number of plant species as well as the number of plants in total in the quadrat were counted by observation and recorded in a table. The percentage of coverage of the plants and grass were also observed in each quadrat out of 100% and were recorded in the table. The quadrat was placed in 25 different spots in the grassland lot and the data were all recorded on the same table for each quadrat, for a total of 25 trials. All the data was collected in a notebook. The duration of the experiment was 1 hour and 30 minutes. Each of the 25 quadrats used in the experiment was measured using measuring tape. Each quadrat had an area of 1m2, therefore a total of 25m2 of quadrats were used. It was hypothesized that plants would have a higher coverage percentage in the grassland while the grass had a lower percentage of coverage. <br>
