Introduction:
The Quercus alba, commonly called the White Oak is one of importance in Eastern United States for its timber. It ranges from (60 to 150 feet) tall. The bark is cracked and scaly with a pale-gray color. The leaves are bright green, shaped long and narrow with a glossy layer. We proposed that at what rate (Early, Middle, Late) do the leaves fall on East Carolina’s Campus for the White Oak Tree? Does the rate change in the regions of California and New York? The White Oak has a broad tolerance for thermal and moisture conditions. Depending on the climate is what factors the rate of the leaves falling.
Methods and Materials:
For this project the group wants to find out around what time of year do all the leaves on a white oak tree

Then the group agreed upon was a white oak tree which is very common on the East Carolina University campus. Then the group found five different white oaks on campus to observe and continue to collect data over time. The materials the group will need are the five trees, paper and writing utensils, and a device to tell us the temperate and the date for that day. First, the group will go out to and start observing at the observing spot. Then, the group will observe how much the tree and surrounding area had changed from day to day. Then after, for a couple of minutes the group will record all the things that the group observed and noticed. Since, the group has begun to observe the trees in early autumn the group unfortuately have not seen too many changes. Then, the group will record how many leaves had fallen off the tree and observe the ground to see the approximate amount leaves …show more content…
There are multiple factors that can affect the amount of leaves fall during a certain period of time. In the “Impact of plant architecture versus leaf quality on attack by leaf-tying caterpillars on five oak species” article, the group found out that in White Oak there is natural leaf tie, which correlates with nitrogen availability in White Oak. Also, White Oka has the capacity to grow in areas such as, ridges, valleys, wet or dry climates, and even in moderately acid and alkaline soils. Because White Oka has the capacity to grow in different climate regions, White Oka would still maintain the color range of White Oak will transition from green to red and to brown color, during October till winter season. Based on this information, the group predicted that the color range and the average amount of leaf fall would correlate moderately positively. Based on the regions (California and New York) should also correlate with the data found from East Carolina University. Another thing is that the group would predict is that the data from New York’s White Oak and the data from East Carolina University White Oak should be more closely related compared with California’s White Oak tree. The reason the group says this is because New York and North Carolina are on the same coast, therefore, they share similar characteristic. However, New York and North Carolina have different

These are very difficult questions for me personally to answer because I live in the Pacific Northwest, and I have seen the beauty of the old growth forests first-hand.
To improve my procedure, there are plenty of different ways to do so now that I have an increased experience with working with a large selection of trees. A major flaw with my research is by having to record the different types of trees in the zone, mainly height. Therefore, having to examine trees that vary greatly from each other. By having trees that represented the whole zone, instead of part of a zone, it would give more accurate information. To achieve even more accurate information, looking at the largest leaf for each tree would give a better
As one looks and studies the old tree and its annual rebirth, one might notice that it is like a form
I will now describe characteristics of various sugar maple growth stages, beginning with the seed stage.
Pinus lambertiana, commonly known as the sugar pine, is found on the west coast in the mountains of Nevada, California, Oregon and Mexico. The sugar pine is the tallest of all pines and has the longest cones of any conifer. It is very important in these regions for both economical purposes and the environment. (Habeck)
The life cycle of a pecan tree has four main components: germination, rooting, sprouting and lifespan and reproduction. The many different elements of the pecan tree life cycle contribute to the growth and development of the pecan trees we see today. The life cycle of a pecan tree has many different elements. The cycle begins with the spreading and germination of seeds. Mature pecan trees produce and drop thousands of seeds to the ground during the fall season. Dispersal of these seeds may be through the water, wind or animals but wind will end up pollinating the seeds. Pecan tree seeds lay dormant throughout the winter and will begin the growth process in the spring. The seeds require an adequate amount of warmth and rain throughout the winter and early spring months. Once the germination process has finished, the seed...
Many old-growth forests across the landscape of northern Lower Peninsula of Michigan contain a mixture of tree species rather than a monoculture. Many researchers have put forward ideas to explain the competition and co-existence of tree species in such communities. A theory explaining competition and co-existence between two species is gap regeneration. Gap regeneration is when a gap is created upon death of a plant individual and a new individual, sometimes of the same species as died and sometimes not dependent on environmental heterogeneity, takes its place (Kenneth Lertzman). Canopy gaps during gap regeneration can be explained by either reciprocal replacement or habitat preference . In a reciprocal replacement, seedlings of one species would be found predominately under large trees ...
I prepared myself for the upcoming adventurous day. I set out along a less-traveled path through the woods leading to the shore. I could hear every rustle of the newly fallen leaves covering the ground. The brown ground signaled the changing of seasons and nature's way of preparing for the long winter ahead. Soon these leaves would be covered with a thick layer of snow. The leaves still clinging to the trees above displayed a brilliant array of color, simultaneously showing the differences of each and the beauty of the entire forest.
...his experiment is to let the groups take home the plants on the weekends so they can record the details of what happens in those few days.

Every student in a lab section planted eight seeds, two in each cell in a quad, to make sure that we had at least one plant for each week for 4 weeks. After planting the seeds we put the plants on a water mat tray to make

In early March I wait for the wintry snow-covered land to melt and the days very slowly warm with the spring weather. Each day that passes I see the light peaks of green fingers slowly making their way up through the dead foliage left over from the cruel and cold winter. The trees too are showing signs of spring with their buds covering the trees and bushes, in just a few long weeks the buds will start to pop and show the initial sign of spring.
