title: Distribution and Abudance of trees in woodlot - lab 2

description: The purpose of this experiment was to quantitatively determine tree species distribution and abundance in an environment using random sampling as well as look at physical characteristics. My partner Phaeba and I compared distances, conditions and diameter of 10 adult trees in the woodlot of York University. The first adult tree encountered on the left side when walking straight into the woodlot was used to collect data. The second tree used to collect data was the one directly in front of the first and was also used as a reference point to collect data for the remainder of the trees. All data collected for the remainder of the trees were the first ones encountered when walking straight in front of tree 2 and into the middle of the woodlot. Consistency and reliability were accounted for because of this. The experiment was carried out on September 25, 2015 at approximately 4:07PM with weather being around 20 degrees Celsius. The experiment was done at approximately 4:50PM. Transect measuring tape was used to collect data. For the first two pairs of trees, there were a lot of garbage and dead leaves on the ground. The sky was clear and there were a small amount of vegetation on the ground. Going further into the middle of the wood lot to collect the remainder of data, it was chillier and it was less sunny. There were less garbage on the ground, acorns and more vegetation on the ground.

title: Field training with plants ( quadrat, transect, trait)

description: The purpose for this experiment was to count the plant populations and communities at a certain location using sampling techniques.50 individual plants of different species were surveyed for this emperiment. The first dataset included transect which was placed randomly on the grassland and walked along with it. The Golden rod flower species was selected to count at every step the flower was available. Flowers that were only one meter away from the transect were counted and others were excluded from the data. Distance from the transect to the flowers and their heights were measured by using another transect in meters. The number of leaves and the flowers were counted manually.The place where the flowers were counted was mostly crowded thats why it was ranked as 3 (very crowded bunch of plants within 50cm) and 2 ( quite a few plants). This transect experiment was done on the grassland behind the Osgood Law School and the temperature was around 25 degrees. Only two lab partners were doing the transect counting and others were involved in the quadrat measurement.

title: A Study on the Abundance and Distribution of the Plant Rhamnus Cathartica at York University

description: The objective of this study is to examine the abundance of the plant Rhamnus cathartica (European Buckthorn). The abundance of the plant was measured through the following variables: diameter at breast height (DBH) of adult tree, canopy coverage of adult tree, distance of adult tree to nearest sapling and the DBH of the sapling. The instrumentation required for this study is transect measuring tape. The study took place in a woodlot at York University on the 21st of September 2015 at 3:00 pm. A parameter of 30 feet was set from chosen starting point inside the woodlot. The soil condition was damp and little sunlight can be accessed from the ground. The field site was littered with various trash, fallen branches and trunks of multiple trees. The study took place at approximately 18° with clear skies and sunny condition. The study was conducted by Aziza, Paula, Sahar and Shahana. The data showed that the average DBH of adult trees is 3.6 inches and average canopy coverage is 81%. The average of the distance of the adult trees to the nearest saplig is 2.63 ft while the average DBH of the sapling 0.37 inches.

title: Lab 2 - Sampling Plant Populations and Communities Using a Quadrat in the Grasslands

description: This Experiment was conducted on September 22, 2015 from, 3:40pm to 4:18pm, at Danby Woods, York University grassland area with my partner, Mohammed. The weather consisted of sunny skies and a steady temperature of 20°C. The grassland terrain mostly consisted of low leveled vegetation which was found in clusters abundant in the area. Using Random.org, a number was randomly generated from 1-20 to determine how many steps were needed to take in between each quadrat in order to eliminate the potential for bias. This was repeated 25 times, the first 13 replicates were taken West in direction, and the last 12 replicates were taken towards the East in direction. Each time the quadrat was placed on the ground a few observations were noted; i) the total abundance of plants which were manually counted one at a time, ii) total number of plant species-classified and counted manually iii) the total coverage of vegeation as well as total coverage of grasses which was approximated by the eye and relativity.

title: York University Grasslands- Dandelion Study

description: The York University grassland was used to collect data on the abundance, height, leaf and flower count of dandelions. Transect tape was randomly placed and was used to measure the location of the plants. Distance was measured by locating the target plant species and recording the value on the transect. Once the target plant species was located the total number of leaves and flowers was also recorded by counting the leaves and flowers. All of the 50 samples found did not have any flowers as they have reached the end of their growth season. The height of the plant was measured using a ruler and recording the distance between the stem of the plant and the start of the leaves. Cover was estimated by observing the immediate nearby area of the sample plant and was recorded as a value between 0 and 3, with 0 representing no plants, 1 indicating few plants nearby, 2 representing quite a few plants, and 3 indicating that the sample plant was crowded by other plants.

title: Staghorn Sumac tree canopy cover, DBH, distance between adult and sapling

description: Data was collected at the Dan Ianuzzi Park at York University on September 21 2015. A transact was used to mark the boundaries in which individual Staghorn Sumac trees, both adult and sapling, were examined. The diameter at the breast (DBH) of both the adults and the nearest saplings of Staghorn Sumac was measured in centimeters (cm) using a 50 meter measuring tape. Following that, the distance between the adult Staghorn Sumac and the nearest sapling of that adult Staghorn Sumac was measured in cm. The canopy coverage of the adult Staghorn Sumac was measured holding both the hands of the researcher in a square and estimated the percentage of the foliage of the Staghorn Sumac that covered the square. Adult sizes were any Staghorn Sumac 6 feet or higher, any Staghorn lower than 6 feet was considered to be a sapling.

title: Diameter and Distance between Saplings and Adult Trees at Osgoode Woodlot

description: Experiment was conducted in Osgoode Woodlot at York University's Keele campus on September 23rd, 2015. A transect was placed from the edge of the woodlot towards the middle of it. Adult trees 3m or taller within 15m of the transect were surveyed, noting their canopy coverage and diameter at breast height (dbh) in mm. Nearby saplings of the same species were also surveyed, and both their distance from the "parent" tree and dbh were also recorded. The height of the trees was estimated by roughly comparing them with our height - anything at least 1.5x our height was sufficient. Canopy coverage was also estimated by making a square between our fingers and looking skywards. The dbh for each tree was measured using the transect tape, while being careful not to wrap the tape around the tree.

title: Quadrat sampling of vegetation types in Yorku Grassland situated near Stong Pond

description: The purpose of this lab is to determine the variety and composition of vegetation found within the grassland situated within York university grounds. The experiment was conducted in the grassland on the east side of campus near Stong Pond. The necessary and required equipments were one 1metre x 1metre quadrat. The data was collected on September 21st, 2015 at approximately 3pm. The temperature at the time was around 19 degrees celsius as well as it was sunny and partly cloudy with a little wind. There were several types of vegetation in the area. The most common ones noticed and was recorded in the data were the small yellow flowers that bloomed in clumps. There were small purple flowers that grew tall and as singles, white small flowers similar to the purple flowers. There were tall flowers that looked like a bulb at the top, it grew as a single flower. There was also another type of grass that grew all over the grassland, it was similar by shape to parsley leaves. There were weed like plants (leaves) similar to those from dandelion plants.The approach to sampling was random sampling. Once arrived upon the grassland sampling began at the edge where the grassland began. An object was thrown (anything thats solid like a ball) at random into the grassland, where the ball fell is where the quadrat was placed. Once the quadrat was placed the different types of plants were counted (richness) and how many plants in total in the quadrat was counted (abundance). Then one person estimated the percentage covered by grass and the percentage covered by other types of vegetation. Only one person did this job so that the estimations were based on one persons perspective avoiding biased data. The process of throwing the object at random and sampling the quadrat was done 25 times and observations were recorded in a table.
