Bivariate Relationships
Problem:
I am going to investigate if there is a relationship between the (explanatory variable) sampling height (cm) and the (response variable) height of the crown of the saplings (cm) that is measured from the base of the crown. Based from the data from study plots of either 1.5 hectares or 2.25 hectares in the Waitutu forest. Trees were randomly selected within the plots and measured during the summer. The plots were selected to be a representative sample of the vegetation growing in the alluvial and terraces sites. Saplings that I am investigating come from the Waitutu Forest, New Zealand around 2001-2008.
I believe that as the height increases the height of the crown will get taller also. I believe this because since I 'm measuring height in both of my variables you would hope there would be a relationship.
Information:
‘A tree sapling is an immature tree with a slender trunk. Depending on the species of tree, a sapling can be between three and 15 years old, and range in height from 2 to 10 feet (about 0.61 to 3.05 m). Saplings differ from seedlings, which are trees that are less than three years old. The principal attributes of a tree sapling, aside from its age, are trunk flexibility and smooth bark; mature trees generally have thicker, darker outer bark. Ordinarily, saplings do not produce fruit or flowers’ .
The height of the saplings crown is taken from the crown base which is ‘an imaginary horizontal line drawn across the trunk from the bottom of the lowest live foliage’ to the ‘crown top which is the highest point of a standing tree’. This is shown on figure 1
‘The large Waitutu State Forest, of nearly 45000 ha, lies in a rather remote setting. The heart of the rarest is 100 km nort...

...aller also. Waitutu Forest has a mixed range of trees, as i only sampled saplings from study plots of either 1.5 hectares or 2.25 hectares i could expect my findings would be similar and could apply my findings throughout Waitutu forest. To make this investigation more specific and more accurate I could take my data of specific species in the Waitutu forest. Another thing that would need to be taken into account is the weather situation. The saplings would grow differently in other weather conditions. Because of this if you took data from a forest in the North Island of New Zealand you would expect different results due to the difference in whether. The saplings would probably grow faster in the North Island because it would be warmer.
Overall I can see the correlation between the two variables sampling height (cm) and the height of the crown of the saplings (cm).
Two members of the group were instructed to visit the laboratory each day of the experiment to water and measure the plants (Handout 1). The measurements that were preformed were to be precise and accurate by the group by organizing a standardized way to measure the plants. The plants were measured from the level of the soil, which was flat throughout all the cups, to the tip of the apical meristems. The leaves were not considered. The watering of the plants took place nearly everyday, except for the times the lab was closed. Respective of cup label, the appropriate drop of solution was added to the plant, at the very tip of the apical meristems.
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
how strong and wise the tree is by all the patterns and age marks on the tree. Rings are features that can tell
The tennis ball is the constant variable factor (the variable that is kept the same, to make the investigation valid). The ball will dropped from increasing heights (cm-25, 50, 75,100,125,150,175,200) and the bounce of the ball will be measured. A sample size of 3 results will be taken from each height the ball is dropped. The same investigation will then be repeated, but one of the independent variables will be changed.
a) The Daintree rainforest at Cape Tribulation, in far north Queensland is diverse in many ways. It holds 12 of the 19 primitive plant families in the world (Cairns Today, 2007). The forest covers an area of 1100 square kilometres and is approximately eighty kilometres wide. This dense and luxuriant rainforest has the greatest diversity than any other in Australia and many in the world. The Daintree is also the home of rare and threatened of being extinct plant and animal species. The importance of this ecosystem is the very high. This ecosystem contributes to the overall health of this plant in many ways. The diversity contributes in the breakdown of pollution and helps to control the climate to name a few. This rainforest also is a great ‘carbon sink’. It has many photosynthesising plants and this allows the control of carbon dioxide (CO2). The plants take in the CO2 from the atmosphere and return oxygen (O2)
Redwoods were named for the color of their bark and heartwood. These trees have a high resistance to fungus and diseases due to the high tanin content in the wood. The dense, fibrous bark has an even higher content, and acts as an insulator from periodic fires which have plagued the countryside for centuries. Though these trees are immense, they have delicate foliage. The needles are narrow and sharp-pointed, and combine to form feathery sprays. The cones are an inch long and typically contain fourteen to twenty-four seeds. The older trees offspring sprout form their parents' roots in order to take advantage of the established root system.
...le would be more than that of American beech because sugar maple produce more seeds than American beech. Furthermore, we study whether the two species co-exist via reciprocal replacement, habitat preference or merely by chance. We believe that habitat preference may be the mechanism of coexistence here and therefore we hypothesize that there will be more American beech tree neighbors as they may represent the most biomass as per our third hypothesis. Thereafter, root sprouting is effective in American beech to give them a greater horizontal growth than sugar maple. Hence, we hypothesize that sugar maple canopies will be less asymmetrical than American beech. Finally, because a nearby canopy may restrict a tree canopy growth in the same direction, we hypothesize that a tree will grow its respective canopy away from its neighboring canopy to receive maximum sunlight.
Not only maple trees have been tapped for syrup. The Birch and Elm trees have been used for syrup, but the maples produce a much sweeter sap than any other tree. "What is more peculiar is that the sap, unlike nectar, does not come from the leaves (they
In the short story, The Shivering Tree, by John McLeod, past experiences are shown to have a profound effect on the development of an individual. Nanabush learns from his past mistakes which results in the growth of his maturity. In the story, Nanabush past experiences give him the ability to learn from his previous mistakes by turning his enemies into supporting allies, which assists him in resolving his conflict with the Juggler at the end. First, Nanabush act of making peace with Owl demonstrates his maturity, which puts in the right direction for success. Secondly, the growth of his maturity is displayed with Nanabush's final confrontation with the Juggler and permanently abandons him.
To some an acorn is just an acorn, nothing more than a nut. The acorn with its tough leathery outside and rich amber color signifies nothing more than the commencement of autumn. To others it represents a great deal of potential. This tiny seed has the ability to endure many adverse effects including long periods of cold temperatures, drought, and human interference. The fragile acorn contains all the necessary elements to become the giant, majestic oak that has come to signify strength. When the conditions are favorable, the little nut will thrive and become an impressive adult tree providing oxygen and shade as nature intended. The most important factor to the budding tree is the environment. Like all other living things, the acorn needs care and ideal circumstances to develop properly. This is also true for humans and their offspring. Creating the perfect environment for an infant to flourish is quite possibly, the single most important factor to the success of a well-adjusted, adult human.
The Western forests are drastically different from what they were like before the European settlement. In pre-European time, the forests were open and park-like with only 25-35 trees per acre surrounded by areas of open grasslands. One could easily ride a horse through the spacious forest. This, however, is not possible in today's forests. Today, for example the Ponderosa pine forests, have over 500 trees per acre, creating thick dense areas of trees, brush, and bushes (President Bush, 4). The pre-European forests were subject to frequent low inte...

This is first introduced when the Maitu Seed (Mother Seed or “Our Truth”) is shown and while Asha is dreaming about a tree growing in the desert (Pumzi 0:44). This scene however, granted the Maitu Seed an important role in the movie. This theme was introduced again when Asha got to her lab and the branch of the last living tree was on display with the title “There Goes the Last Tree” (Pumzi 4:05). This was a dead giveaway that deforestation plays a major role in the development of the story. It demonstrated the importance of trees as well.
Trees are usually considered as bland, unusual objects that are usually taken for granted; however, I believe there is more to a tree that meets the eye. They supply oxygen and shade. During the holidays, trees are able to spread holiday cheer by wearing holiday decorations. Through providing, they are always beneficial to the needs of others. Rather than having striking beauty like a flower, trees have are grounded and possess a gentle beauty; they are adapted wildflowers to their environment. In fact, if I had to compare myself to an inanimate object, I would choose a tree. A tree has many characteristics in common with me. Characteristics like relying on our roots, strength and observation, and helping others and leaving behind a powerful legacy are a few of the traits we share. All of which I believe are admirable qualities to possess.
a forest is to leave it to nature. A suitable seed bed in which trees will
