Discuss the relative importance of physical and human factors in accounting for changes to vegetation over time within ecosystems in the British Isles (40 marks) The British Isles can be found in the Northern Hemisphere where deciduous forest is the main biome. Here physical and human factors have accounted for changes to the vegetation for many years. Human factors can include tourism‚ agriculture‚ urbanisation‚ interception and deforestation. Physical factors can be such things as natural disasters

Forest Management and why studying it is important? Forest Management is basically providing the forest proper care so it stays healthy and vigorous and provides the products and values the landowner desires. I believe that the reason why studying forest management is important for the students of today is because the children of today are the future so they SHOULD know the techniques and methods applied in order to manage forest because there are many aspects of our life that are interconnected

There are many factors that account for the changes to the vegetation over time within ecosystems in the British Isles‚ such as human activity‚ climate‚ soil‚ light availability and intensity and natural disasters. The characteristics of the vegetation that are influenced by these factors are height‚ distribution‚ variety of species‚ adaptations and density of the vegetation. Some of these factors have relatively little influence on the succession development‚ whereas others have a dramatic influence

Temperate Broadleaf Deciduous Forest The Temperate Broad-leaf Deciduous Forest are found mostly in the Eastern part of North America. This is where most of the forests have survived. The leaves of these trees change colors through the seasons. The colors that the trees may change are reds‚ oranges‚ and golds in the autumns. The leaves change colors‚ then when winter rolls around most of these trees lose their leaves and the plants around this area become dormant. The climate in this area is very

The Forest Tent Caterpillars latin name is Malacosoma disstria Hubner and is native to North America. They can be found through forests that contain hardwoods and are most prolific in the eastern parts. Trees that the Forest Tent Caterpillar attacks in New York are basswood‚ ash‚ sugar maple‚ alder‚ cherry‚ elm‚ apple‚ aspen‚ birch‚ and oaks. Trees that are not hosts for this pest are conifers‚ red maple‚ and sycamore. The New York State of Department of Environmental Conservation also says that

Tropical evergreen forest Tropical forests are characterized by the greatest diversity of species. They occur near the equator‚ within the area bounded by latitudes 23.5 degrees N and 23.5 degrees S. One of the major characteristics of tropical forests is their distinct seasonality: winter is absent‚ and only two seasons are present (rainy and dry). An evergreen forest is a forest consisting entirely or mainly of evergreen trees that retain green foliage all year round. Such forests reign the tropics

Writing Assignment Resource Management Policy The National Forest Management Act (NFMA) of 1976 is a federal law that reorganized‚ expanded and amended the Forest and Rangeland Renewable Resources Planning Act of 1974‚ which called for the management of renewable resources on national forest lands. The National Forest Management Act requires the Secretary of Agriculture to assess forest lands‚ develop a management program based on multiple-use‚ sustained-yield principles‚ and implement a resource

The article „ Fish in Offshore Kelp Forests Affect Recruitment to Intertidal Barnacle Populationa“ written by S.D. Gaines and J. Roughgarden is about the influence that the composition of kelp forestes has on the recruitment of barnackle. The giant kalp lives in the pacific ocean of America and its composition depends on currents‚ predators‚ herbivores and weather. To study the inshore recruitment of barnackles they took probes of the klep beds inshore and offshore and analyzed the density of plankton
