Study of Woodland
Aim
Our aim was to study two different areas of woodland that have been
cut down at different times, and to study the diversity and the
abundance in the ground plants in each of them. The two coppices are
close to each other. The two coppices are 7(young) and 30(old) years
old. Our main aim here is to check the diversity and abundance between
the 2 coppices, plus comparing the species.
Hypothesis
I think that there will be more bio-diversity in the young coppice. I
think this because the old coppice will have had more time to develop,
and there will be a developed canopy, which will let through only
enough light for the shade tolerant plants. The young coppice,
however, will have a spotted canopy, and a much larger variation of
plant life, as the light amounts from place to place will vary.
Factors affecting Abundance/Diversity
There are a many factors that that we want to monitor, as these are
the factors that will affect how the plants have grown. These will all
affect the plant's life in some way, whether it turns to be a large or
small factor.
Light
Light is possibly the most important part of plant growth and
survival; and light is measured in LUX. We use the environmental meter
to measure light. Photosynthesis is what feeds the plant, and
therefore keeps it alive. Basically, it is the source of energy that
every plant needs to grow. This reaction happens in the leaf, and this
happens because of the chlorophyll in the leaves, which give them
their green colour.
Temperature
Temperature is also an important factor. This is because it can vary
so much, and certain plants will not be used to certain temperatures,
for example a tropical plant wouldn't survive long over here unless it
was put in a greenhouse. Temperature is another factor that is
measured with the environmental meter, and it is measured in Celsius.
The reason temperature can make such a difference to plants is that it
“We’ve always known that spending time in nature is good for us, but now we have real evidence that spending time in the forest, specifically, can create measurable changes in our bodies and minds that have a significant effect on out health”.

In The Dull Knifes of Pine Ridge by Joe Starita, Starita focuses on five generations of the Dull Knife family which goes from the 1870s until the present. He starts by asking the reader to visualize the history of the Dull Knife family and how they had to adapt and were able to survive after the Northern Cheyenne were forcefully removed from the northern plains to Oklahoma Indian Territory and 3 back to the northern plains again. The story started with Guy Dull Knife Sr. living in a convalescent home in Colorado and would start to trace his ancestry back to the original Chief Dull Knife. George Dull Knife, his son, was born in 1875, most likely came north to the Pine Ridge reservation many years after and found his identity with the Lakota rather than the Northern Cheyenne. George
All species, including plants, are impacted by density. Plants, of course, cannot leave their habitat as animals can, so they tend to respond in different ways to density. As populations grow more dense, they compete for resources such as food and space and are more prone to disease. Less dense populations are more susceptible to predation pressure.
The people of the Eastern Woodlands made many tools to help them in their everyday lives. They made spears, weirs, nets, bows and arrows, lances, knives, taps, snares and deadfall for hunting. Most of those tools were made of wood or bark and other forest material. Arrowheads were made from chert, or flint, from sedimentary rocks. They were shaped like isosceles triangles, the smallest arrows were used for hunting birds, the bigger ones were to spear bears or deer. Flint knives were often oval, or teardrop shaped. For fishing they made spears, weirs, and nets. They also made canoes from hollowed-out trees to help with fishing in the lakes and streams. Some other tools they made were axes made of stone to strip bark, clear fields and removing fat from hides. Axes
Carbon dioxide is necessary for plants to carry out the process of photosynthesis, which is an important process because it allows plants to produce glucose, as well as oxygen. Based on evidence from previous experiments, the growth of the plant will reflect the amount of CO2 gas that is present in the environment (O’Leary and Knecht 1986). This means that the plant growth relies on the carbon dioxide in the atmosphere in order to be successful. Therefore, in several cases, it has been noted that when the concentration of CO2 is doubled, the plant growth will similarly increase (Carter et al. 1997). So, it can be concluded that by raising the amount of carbon dioxide in an environment, the surrounding plants will experience an increase in growth.
How does the vegetation surface type affect the amount of runoff? Speculate why this happens.
My group, fertilizer group 3, is testing the variables of plant color and number of leaves. Fertilizer can affect that drastically! Those two variables are basically what determine a healthy plant. Fertilizer can help to boost the minerals in the soil and give the plant what it needs to survive and be healthy.
Plant hormones are certain chemicals present in plants that control plant growth and development by affecting the division, differentiation, and elongation of cells. (Campbell, 2008) Each hormone has multiple effects depending on its site of action, its concentrations, and the developing stage of the plant. (Campbell, 2008) Auxin is a plant hormone that is synthesized within the apical meristems and young leaves of a growing plant. Auxin stimulates stem elongation when it is present is low concentrations. It promotes the formations of lateral and adventitious roots, regulates development of fruit, enhances apical dominance, functions in gravitropism and phototropism, promotes vascular differentiation, and retards leaf abscission. Gibberellic acid is one of several plant hormones that govern a plant’s growth. Gibberellins allow for stem elongation in plants. Plants without enough of this hormone tend to grow short or stunted. This chemical is high in the element potassium, which is one the main components of plant fertilizer and very important for plant growth on its own. The...

Plant defences are those mechanisms employed by plants in response to herbivory and parasitism. According to Hanley et al. (2007), “the tissues of virtually all terrestrial, freshwater, and marine plants have qualities that to some degree reduce herbivory, including low nitrogen concentration, low moisture content, toxins or digestibility-reducing compounds”. The type of chemical defence may be species specific (Scott 2008). The defences that plants possess may be in the form of chemical production or in the form of physical defences such as thorns or spikes and even through reinforced, rigid leaves. “The compounds that are produced in response to herbivory can either have a direct effect on the attacker itself (e.g. toxins or digestibility reducers), or serve as indirect defenses by attracting the natural enemies of the herbivores” (Bezemer & van Dam 2005). This essay will focus on chemical plant defences and in particular the effects of terpenes, phenolics, nitrogen-based defences as well as allelopathy in plants.
Each plant species has a unique pattern of resource allocation that is genetically determined but not fixed. Plants can adjust there allocation pattern when they experience different environments and the presence of other species. Phenotypic plasticity goes hand in hand with resource allocation as well. When a plant has to adjust itʻs resource allocation, sometimes it uses itʻs resources to help the plant grow different characteristic so that the plant can have a greater chance of living in the environment. For example, if a plant from an environment that does not experience wind on the regular basis enters a new environment that has a lot of wind the plant may change itʻs resource allocation and spend more of itʻs resources growing deeper
In the story The Thing in the Forest written by A. S. Byatt, the characterization of Penny and Primrose is portrayed as very similar individuals. They both start out in the story as young girls in a world of conflict. This world of conflict helps represent the main theme of the story and their lives in response to the conflict. The main idea of the scary thing in the forest, that they think they saw, symbolizes their response to their childhood experiences as something realer than themselves as the characters both relate this in the story The Thing in the Forest as not even remembering their father's presence before dying at war. They both experienced the terrible childhood and both were affected by it, even without intentions the conflict
Plants are grown under controlled and sterile conditions which reduce the risk of being exposed to pests, pathogens and diseases.
A State Forest & nbsp; Last autumn, while on a trip, I decided to walk through a State Forest. This huge forest enriches the countryside not far from town and was a place where Indians held hunting rights until recently. Little streams, ancient trees, shaded paths, and hidden places are some of the physical attributes that make the State Forest an enchanting place. & nbsp; I wandered leisurely along the shadowy paths, enjoying the peaceful surroundings. With only the songs of birds for company, I felt completely isolated from the crowds and traffic as I walked over the deep carpet of leaves. It had begun to rain a little when I first started my journey.
The effect of soil salinity in plant growth is part of botany, the study of plants.
