There is clear difference in seed dispersion and tree density in woodlot and Oldfield, the key difference relies on the type of habitat it nurtures and the kind of growth it allows. Some of the observed differences in Oldfield, that it’s an open place with constant sun which causes higher temperature, there are no trees but more flowers, the ground is not wet, there was not many animals inhabiting it, and it is less diverse compared to woodlot. According to this study, Animal species abundance, are thought to be correlated with size of natural environment and resource availability3. Furthermore, it was confirmed that species distributions are influenced by elements like soils and habitat factors3. On the other hand, woodlot had more shade which led to cooler temperature but higher humidity, it was more damp and wet. Furthermore, it is established by this research, that the difference between the average (daily) temperature of two habitats; a denser habitat and an open-field one was generally found to be highly significant value (p < 0.0001), and the average of the Relative Humidity was found higher in the forest /woodland habitat than an open-field1 …show more content…
There have been solid connections between tree distributions, and its abundance to the soil nutrient that it inhabits4. Other factors such as Accessible light, water supply and temperature also influences the success and growth of tree species1. One difference why Oldfield showed more percentage of species covering the ground is because Oldfield is abundant in grass fine leaved and flat leaved while that is not common in
Shortleaf pine tends to grow rather slowly in the early stages of its life when compared to its closest competitor, loblolly pine. Therefore it cannot compete for the best sites under natural regeneration, but, because of it's tolerance of a wide range of site conditions, shortleaf pine is found naturally in areas where loblolly pine will not grow effectively. It is for this reason that shortleaf pine was chosen for this site instead of loblolly. When planted artificially, it was found that after the first few years of development, shortleaf pine will match loblolly in height growth on the better sites and will surpass loblolly on the poorer sites (Harrington, 1987). Because of this, shortleaf pine is the most commonly regenerated pine in the northern and western parts of its range where the site conditions are not as ideal as in the southern part of its range.

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.
I am going to identify the plants in each area and count them. I will
Depending on the biomes, rainfall and soil can vary. However, the rainfall is typically ranges from 30 cm to 200 cm. In mountainous regions and forest biomes, there would be plenty of rainfall. While in the grasslands, there’s little rainfall. In the temperate zone, there are two main types of trees, coniferous and deciduous. The deciduous trees, in the South, drop their leaves in the winter. Generally, the trees are usually small in height unless in the forest areas. The forests tend to have wide leaves and tall, large trees. The soil in deciduous forests is found to be very fertile. The different amount of rainfall in the forest areas and the grasslands cause the difference between the trees and plant height. The rainfall in forest regions can lead them to be very common with the rainforests. Furthermore, the changes and variation of weather could be the reason as to why the forests shed or don’t shed their leaves. The leaves show a correlation between the fair amount of sunlight during the summer causing the leaves
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
A population of Plantago lanceolata (ribwort plantain) on the path was found to have higher trampling tolerance than populations away from the path; this reflected the sharp differences in the conditions of the plant at these sites. Ribwort Plant had generally a higher tolerance to trampling than any other plants as more were found on the path, but there were less compared with other plants as distance increased from the path. These results suggest that the competition level found on the path was sufficient enough to impose a selection pressure for the evolution of tolerance in a sensitive species, but in some areas the distribution of Ribwort Plantain were the same. This provides that other conditions affect the tolerance of trampling for Ribwort Plantain.
The ecozone's forests are composed of 12.8% mixedwood, 2.1% deciduous, and 0.2% coniferous trees. The forest cover spans from 3 to 16%, and 40% of Ontario's rare plants are exclusive to the Carolinian forests. The Wood Poppy, Small-whorled Pogonia, Prickly Pear Cactus, and Cucumber Tree are species listed as Endangered. Wild Raspberry, Black-eyed Susans, Clover, Goldenrod, and Trilliums are widespread in forest ecosystems. Thickets and abandoned fields are h...
Sugar pines are found in a variety of places including moist, steep, north, east and south facing slopes. They tend to like deep, well drained soils that have a slight to neutral acidic level. While these trees can and do grow on steep and rugged land, the best growth occurs on gentle terrain at middle elevations in sandy to clay-like soils. These sugar pines grow from sea level up to a maximum of about 10,000 feet. The ele...
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 celebrate the use of black grama (a decreaser) and prickly pear (an increaser) as range condition indicators and applaud the committee’s use of flora in addition to fauna. However, distribution of black grama is limited throughout the sub-geography selected. If this geography included the short-grass steppe the distribution of black grama would suggest it as a much better landscape representative.
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...
Paul Celan composed his feelings for his mother regarding both her life and her passing in his poem “Aspen Tree.” The entire work is a vessel for his emotions toward her early departure and comparisons of the life she lived with various objects in nature. However, one emblem in particular perfectly represents Celan’s idealization of his mother. It can be argued that Celan uses the dandelion to epitomize his mother’s life because it highlights his themes of transiency, the light of life within darkness, and the cheating nature of death. Comparison between the dandelion, other wonders in nature, and his mother’s life support this claim as well as contextual hints from the piece itself.
One of the reasons for loss in biodiversity is alteration of habitats. A habitat is the natural environment in which a species of living organism lives. If the habitat of a species is changed, it will cause the species to die or migrate to other places where it can find its natural habitat. There are many ways in which the habitat of plants and animals can be altered. One of them is land use changes. Since the beginning of human life, human beings have been changing land use for farming. Large areas of forests have been cleared by humans to increase the area of farming to satisfy their growing needs. Many biodiversity-rich landscape characteristics have been lost due to intensive farming (Young, Richards, Fischer, Halada, Kull, Kuzniar, Tartes, Uzunov & Watt, 2007). For example, traditional farming was replaced by private farms in Europe after the First World War causing an immense change in land use patterns. Another major proble...
The biosphere is sufficiently larger than anyone could ever imagine. It could possibly have up to thirty million different types animals, plants, fungi, and all other organisms. Considering the ocean covers seventy percent of Earth and all of it’s matter, scientists and oceanographers have only explored and mapped five percent of it. This amazing fact shows us, humans, how little we all know about the biosphere. The life forms of the biosphere of Earth vary from animals, plants, fungi, and various others. Out of the possible thirty million different species of life forms, scientists have only discovered a small portion of over one million of them. Every single one of these species need trees...
