title: Utilizing Line Transect Methods for Sampling Common Milkweed Plants in Grassland near the Danby Woodlot at York University

description: The purpose of this observational study was to utilize the line transect method, i.e., a distance method, for sampling purposes, to meausre characteristics of the Common Milkweed plant (Asclepias syriaca), i.e., plant height, number of leaves, number of flowers, and level of crowding, and to use the distance on the transect measures from the plants as a means to estimate the population abundance of this plant species in the Grassland situated near the Danby Woodlot at York University, which is the location where this study was conducted. This study was conducted by group members Gajamugan Rajavarothayan, Gopaul Parbatie, Albert Lin, and Hannan Fayyaz from 3:25 pm to 4:00 pm EDT. A transect tape was randomly placed in a straight line stretching 20 meters in the Grassland situated near the Danby Woodlot at York University, specifically in an area that had the presence of the target plant species, i.e. the Common Milkweed plants. As we walked along the transect line, we recorded the distance on the transect whenever a Common Milkweed plant was visible near the transect tape, i.e. within 2 meters from the transect tape, to estimate the population abundance of this plant species in this Grassland area near Danby Woodlot at York University. We also measured the plant height using a second transect tape from the ground up to the tip of the largest leaf in the Common Milkweed plant, i.e.. the largest leaf in the plant was actually lifted to as high as possible and this height was recorded as the plant height. Gajamugan was the one who read all the measurements from the transect tape to ensure errors are minimized as the measurements for both the distance on the transect and plant height were recorded consistently by the same person. The number of leaves and number of flowers was recorded for each individual plant, and the level of crowding for each individual plant was scored from 0-3, whereby 0 = open, 1 = some plants nearby, 2 = quite a few plants nearby, and 3 = very crowded bunch of plants nearby within 50 cm. In total, our sample size, n, was 20 individual Common Milkweed plants. The conditions at this site at York University had an atmosphere temperature of 23 degrees Celsius, the weather was partly cloud, wind speed was 16 km/h blowing from the East, and the humidity level was 63% and the soils were not dry but rather they contained some moisture. The height of the grassland vegetation in area we used to sample the Common Milkweed plants was below 0.5 m, I.e., below knee level. However, in neighbouring grassland areas from our site that contained other plant species, the height of the grassland vegetation increased and was around 1-1.5 m, i.e., above knee level. Insects like lady bugs, bees, and flies flew around our site as well. Hence, overall these factors provided adequate conditions for viewing the plants and recording measurements from it.

title: Woodlot Dataset 3: Sampling Adult Trees

description: This experiment was conducted on September 22, 2015 in the Danby Woodlots on the York University Keele campus between 4:40pm-5:10pm in collaboration with Naduni, Bryson and Stanley. The experiment was conducted on a bright, sunny day with clear skies with an external temperature of 22°C, however due to the canopy size of the trees in the Danby Woodlot, very little light got through and the actual site of the experiment was dimly lit. The purpose of this study is to get field training with plants and to familiarize myself with using sampling tools, such as transects, to collect data. This study was conducted by starting on the edge of the Danby Woodlot and using transect tape, we walked in a straight line towards the center of the Danby Woodlot. Every time we encountered an adult tree along our path (an adult tree is defined as a tree 2 times the observers height; at least 355.6 cm) we measured the diameter of the tree trunk at the observers breast height (137 cm) using transect tape. We also gave the observed adult trees a classification between 0-2 to represent the current state of condition of the tree (0 means the tree is dead, 1 means the tree is alive and 2 means the tree has a huge green canopy). Lastly, we also measured the distance between the current observed adult tree and the previously observed adult tree using the transect tape. After the 10th adult tree we observed, we ran out of transect tape so we used a random number generator and set the parameters to between 1 and 20 and got the random number 11. We decided to walk 11 steps North of where the 10th adult tree was and then set out the transect tape and walked in a straight line until we observed a total of 20 adult trees. The specimen of trees that were observed are Sugar Maples, or also known as Acer saccharum. This specimen was identified by observing the leaves of the studied trees and comparing then to the pictures provided in the Leaf Guide within our BIOL 2050 lab manual. The variables observed in this study were continuous and ordinal.

title: Biol 2050, Week3 Lab

description: The data collected is from Saywell Woodlot located at York University, Toronto. Conducted on September 21, 2015.<br>The data was collected my initially laying a transect at the edge of the woodlot and walking in a straight path further into the woods, once a adult tree (no specific species were used) was found (which was decided as atleast 5 meters tall), it would stand for our initial tree. Measurments based on the tree's diameter, follage level, as well as closest living adult tree were documented. The diameter was measured with a measuring tape at breast level, to ensure we measure each tree at the same spot. The follage level was determined by making a square with our hands and roughly estimating the percentage coverage, level 0 would be anywhere under 25% coverage of tree to sky ratio, level 1 would be anywhere between 25%-75%, and level 2 would be 75%-100%. a measure to the next closest tree was measured using a measuring tape. The tree cloest to the first tree would also be recorded for their height and follage to sky level.

title: Sampling Tree Populations via Transects - Woodlot, Dataset 3

description: The following data set was collected in the Danby Woodlot area at York University on September 22nd, 2015 from 3:30 to 4:30 PM. The temperature of the area during the time of data collection was 21˚C with sunny and clear overall conditions. My group members, Amanda, Phenil, Tonia, and I were assigned four different sets of data to obtain by our instructor. Each group member was then assigned one set of data to obtain individually; I was assigned dataset three. The group was then split into pairs of two so that each person had a partner to help them obtain their required data for their data set; I was assigned Tonia. Tonia and I then headed to Danby Woodlot area to begin our data collection. A transect measuring tape was unwound and extended from the edge of the Woodlot area to the center of the Woodlot area. The transect was then placed on the floor and used as a straight line to follow during data collection. Starting from the edge of the Woodlot area, the straight line was walked towards the center of the Woodlot area. While walking the straight line, Tonia and I had encountered an adult tree in our path. An adult tree is one that is twice the height of myself, approximately greater than 134 inches. The distance between the encountered tree and the next tree found along the path was measured at breast height in inches and the two trees were classified as a pair. The diameter of each of the two trees was then calculated at breast height in inches. All measurements were done with a second transect so that our path was not disturbed and results remained consistent. Each of the two trees was then given an overall health rating. Each tree was given a rating of either 0, a dead tree, 1, a living tree with some leaves, or 2, a living tree with full canopy of leaves. This process was repeated with 9 other pairs of trees found further along the straight line. All raw data was first recorded by hand in a notebook and then transferred to a Microsoft Excel document. In the field, this lab allowed BIOL2050 students to increase their knowledge on different sampling techniques as well as better their ability to obtain data. Outside of the field, this lab allowed students to better describe their metadata and increase their ability to share their findings with the greater scientific world.

title: Sampling Plants using Quadrats in Grasslands

description: The data was collected at York University campus in the Danby Woods, on Tuesday, September 22, 2015 around 2:45-5:15pm. It was collected to determine the sample populations of grassland plants in that area. This dataset collected data using quadrats that are one meter by one meter in length. The quadrat was placed randomly on the ground 25 times in order to get a sample of the plant population of the entire grassland area. In order to get random areas of the entire grassland, a random number was chosen and the quadrat was placed down after that many steps were taken. The data that was recorded from each quadrat was the total abundances of plants, the total number of different species, the total cover of all vegetation, and total cover of grass. The total abundance and total number of species was determined by counting the individual plants. The total cover of vegetation and grass was determined by estimating the amount of area it covered relative to the area of the whole quadrat. The entire process of this dataset took around a 1 and ½ hour or so. The temperature was around 21-22°C. Group members include Katie, Katherine, Adam, Ava and I.

title: Ecology Field Study - Grassland, Dataset #2

description: The group divided in half (between working on transects and quadrads). This was the first field assignment we conducted. This occured at the grassland area on York University's Keele Campus. Using transects, we ventured into the grassy terrain, laid out the transect, and measured from the starting point of a particular plant species. Along the transect, we stopped to record measurements of flowers leaves, and how crowded the target plants were (on a scale of 0-3). Measurements were taken using a second transect, and were recorded in chart form. The study site was a relatively dense grassland containing varied grass and flower species.

title: Goldenrod Transect Dataset

description: In this experiment, a dataset was collected for 25 goldenrods in the grasslands in York University. To begin, a transect was laid down randomly within the grasslands at Pond Rd. in York University. I walked along the transect and recorded the distance of goldenrods, plants with bright yellow visible flowers, on both sides of the transect in meters. After recording the distance, the height of each goldenrod was measured with a spare transect. To measure the height, I held the transect vertically, starting from the highest point of the plant, the flower, to base of the stem. The height was also measured in meters. Then I counted the number of alive leaves for each goldenrod for which I had already measured the distance and the height. I defined alive leaves as all the leaves that had not dried up. After counting the leaves, I checked the goldenrod to see if it had any flowers. I recorded the each goldenrod. Some goldenrods had a bundle of flowers at the top of the plant. These bundles consisted of small flowers in close proximity to one another, which were separated by small branches bearing no leaves. As a result, I defined each bundle as 1 flower. Lastly, I examined the surrounding of each goldenrod for other plants. Using a scale of 0-3 in terms of crowdedness, each goldenrod was either assigned a 0 if it was in an open area, 1 if there were some plants near the goldenrod, 2 if there were quite a few plants surrounding the goldenrod and 3 if the goldenrod was surrounded by a very crowded bunch of plants within 50cm.
