title: Adult Tree Density in Saywell Woods

description: The location in which the study was conducted was Saywell woods at York University. The temperature was around 20 degrees Celsius and sunny with a few clouds. We collected data by lying the transect measuring tape from the edge of the woodlot to the centre. Following along the transect anytime an adult tree was met, its diameter was taken and the nearest adult tree's distance was calculated in centimeters. The nearest trees were on either side of first tree and not along the transect like the first. Once the distance from the first adult tree to the second was calculated, the second trees’ diameter was taken in centimetres. The trees that were considered adult trees where the trees that were twice our height. After the distance between each tree and their respective diameters were recorded, the first tree's appearance was used to categorize it's condition. The trees’ condition was ranked on a scale from 0-2, 0= dead, 1= living, 2= huge green canopy.

title: Using a transect to sample adult and sapling Red Maple trees in a York University woodlot

description: The data was collect on September 21st, 2015 from 3:00pm to 5:30pm. The location of data collection was in the Danby Woodlot on the York University campus. The research was conducted on a sunny day in around 20 degree celsius weather conditions. The sun did not shine as strongly in the woodot as opposed to on the grassland due to canopy coverage from the large trees present. This research was conducted by myself, Taylor Kerekes. I was also assisted in the data collection by my group member Frankie. To start the data collection a transect tape of 30 meters was laid down from a designated starting point in the woodlot. I, the researcher, then walked along the transect and made observations of trees up to one meter away from the tape. Red Maple trees were chosen as the species to sample for the data. The trees were easy to spot from the transect line due to them being immobile organisms. 10 Adult Red Maples were chosen which were designated Adults by the height of them compared to the height of the researcher (trees must be double the height of researcher to be considered adult). For every adult Red Maple the closest sapling of the same species was found and the distance was measured with the transect tape in inches. The diameter at breast height was also measured for both adult Red Maple and corresponding saplings. This was recorded in inches as well.The canopy coverage of the adult trees was measured by creating a square using the fingers of the researcher and estimating the precentage of the sky the trees leaves were covering. The accuracy of this technique is questionable however it makes it easy to compare the canopy coverage of the samples in comparison to eachother. When putting down the first 30 meter transect only 4 adult Red Maples and saplings were found. A random generator was then used in order to decide how many steps would be taken before placing a second transect. 23 steps was decided, and the second transet was laid. I again walked along the transect observing the Red Maples up to one meter away. The remaining 6 adult Red Maples and saplings were collected on the second transect line. This data collection was done to exhibit how transects are used and how to collect data with them. Different methods are used when transects are involved. The random sampling technique was used and the importance of accuracy was understood when collecting this specific data.

title: Distribution of Adult Trees and Saplings of Same Species

description: Inside a woodlot, adult tree was randomly selected. Then, the diameter of the tree, at 4 feet from the ground, was measured. The diameter was measured by holding a measuring tape to the tree and recording the distance from one end to another. After, the canopy coverage was measured by forming a square using thumb and index finger of both hands, and holding it up towards the sky. The percentage of sky covered by the tree inside the square was estimated and recorded. Next, the nearest sapling tree of the same species as the adult tree was found and the distance from the adult tree to the sapling was measured and recorded. Lastly, the diameter of the sapling was measured at the thickest part of its trunk. The whole process was repeated nine more times with trees of the same species as the first replicate.

title: Woodlot Dataset 4: Lab 2

description: Lab 2 of BIO2050. Experiment occured at 3:00-4:10 PM on September 22, 2015 at York University Danby Woodlot with the assistance of group member Kathy. Group members: Kathy, Khaula, and Houra (completed datasets 2, 3 and 1). Ten random adult silver maple trees were selected in the Danby Woodlot. Using transect measuring tapes, my partner and I measured their diameter at breast height (in inches) and made an estimate of the extent of the trees canopy coverage (percentage) by forming a square frame with my fingers and viewed how much sky was visible in that selected area of the canopy. The distance of the nearest silver maple sapling from each adult tree was measured with the transect measuring tape (in feet) from the adult trunk to the saplings trunk, as well as the sapling's diameter at breast height (in inches).

title: Lab Techniques for finding traits of plants: Woodlot data set 4 Silver Maple mature trees and saplings

description: The data was collected on Monday September 21, 2015 from 3:00pm to 5:30pm at York University’s Danby Woodlot. It was a sunny day, very little cloud and hardly any wind. Data that was collected was diameter at breast height of mature trees and saplings, canopy coverage of trees and distance to nearest sapling. My partners Mustafa Alan and Krystal Nguyen and I collected the data. Discussion of how to proceed with the collecting the data took place in the lumbers building at York University, room 119. I chose woodlot data set 4 using the transect method and Mustafa chose grassland data set 2, we both helped each other collect data for both sets. My partners and I walked to Danby Woodlot with the rest of Lab 1, we found a clearing with minimal trees and labeled this the middle of the woodlot. From this mid-point Mustafa placed a transect down and measured out to the other end straight across till it reached the opening of the woodlot facing York University. The types of trees were observed and silver maple trees were the most abundant so this was chosen as the sample. 10 randomly selected silver maple trees found along the transect were used. Mustafa Alan took measurements and I observed and recorded the data. Starting with tree one closest to the middle of the woodlot, diameter at breast height (inches) was measured with another transect. The second step was making a square with our hands and determining the coverage (%) that the sample tree gave off (note: that the tree could have had over 100% coverage as some of the canopies of the trees overlap). We then observed where the nearest sapling was located to the mature sample tree and Mustafa measured the distance between the two (note: less than the height of two average people, determines a sapling). The last step was taking down the diameter of the sapling as well using a transect. These steps were repeated for all 10 silver maple trees selected along the transect. Data was recorded on a table in my notebook and then transferred to a Microsoft excel spreadsheet that also displayed meta-data for each variable. The data was collected for Ecology 2050 Lab 2 group 1 and the purpose of collecting this data was to gain skills in ecological experimentation and methods of collecting field data, displaying this data, and communication through descriptions and meta-data.

title: Grassland Dataset 2

description: This lab was conducted by sampling a specific plant species called <em>Cricus vulgare</em> using a transect on York University grasslands near Strong pond which took place on September 22, 2015. S. Govinda recorded the data on notebook while S. Lam identified the plant, and took measurements. The study site was very dense with vegetation all around the pond. A transect tape was randomly placed which extended 30 metres towards the pond. The plant that we selected was the Field Thistle(<em>Cricus vulgare)</em>. An individual would walk along the transect tape and everytime the target plant was visible, they would record down the distance from the transect, the height of the plant, number of leaves, number of flowers, and the crowdness level. In order to measure the distance from the transect the individual walked in a straight line from the plant towards the transect tape, making note of the distance on the tape in metres. We used a second transect to measure the height of the plant that we identified by in metres, placing the tape to the ground to a leveled surface, measuring to the highest point of the plant regardless of leaf or flower or stem. The method used to count the number of leaves and flowers involved a quick observational count of the visible flowers or leaves excluding dead flowers or leaves. Crowdness level of the identified plant was observed by the number of surrounding plants within a 50cm distance which used the scale from 0 to 3, 0 indicating that there are no plants within 50cm, and 3 indicating that there are other plants obstructing the identified plant. This process was done for a total of 50 individuals in one transect.

title: Diameter of Red oak trees and the Distance between pairs in Danby Woods

description: The data was collected on Tuesday, September 22, 2015 in Danby woods at York University Keele Campus from approximately 3:30 pm to 5:00pm. The temperature was in the low 20 degrees celcius and the skys were mostly clear. The temperature in the wood lot was a little cooler. All four members (Richer Lai, Felicia O, Dylan C, and Brandon B.) collected the data.
