Lab 2 Plant Observation.

Transects measuring tape was used to record the diameter of 10 randomly selected trees of the same species in the wood at York university. The weather was clear and the sun was shiny and a perfect day to go out and study the environment. The study started approximately at 3:00 pm on Monday. The woods were covered with different types of trees so only one species was picked (probably the most common one) and 10 random trees of that species were. Diameter of the trees were measured and recorded. The species of the tree studied is either Elm or willow. Once the diameter of the randomly selected adult tree was measured, I looked for a sapling of the same species nearby, the distance between the adult tree and the sapling was measured (which should be near the adult tree) and the observations were recorded. After measuring the distance between the sapling and the adult tree , the diameter of the sapling was taken using the measuring tape (usually it is tiny compared to that of the adult tree). All observations were recorded. For the coverage of the adult tree, I used a camera to take a still image of the tree (is was the equivalent of making a square with the fingers. Then I looked at the picture and estimated how much sky I saw. Its was decided that too much of the sky means the leaves coverage. After writing down all the observations percentages were estimated. Branches of the trees were shook whenever I faced a problem locating its leaves since most of the trees are entangled to each other. It was made sure that all description of study site and recordable environment condions and the time of the day were written down.
