Timber Harvesting Methods That Encourage Forest Regeneration

Timber Harvesting Methods That Encourage Forest Regeneration A major portion of the practice of forestry silvicultural systems is timber harvesting methods designed to ensure successful and succeeding forest stands for the future. Without the application of these methods of reforestation, there would only be random tree stocking of both preferred and non-preferred species leading to major shortages of wood and trees demanded by the consumer. Nature, when left alone, uses its time-consuming natural process of reforestation and is appropriate in many situations. On the other hand, foresters may need to manage for a forests best use when forest owners and managers need reliable income and other necessities in an appropriate time frame. Many of the accepted forest regeneration concepts were first introduced to North America by German forestry professors during the late 19th Century. Germany had practiced these forest reproduction schemes for centuries and one of the earliest books on the subject was written by German forestry pioneer Heinrich Cotta during the late 17th century. These western European educated foresters were first to define the profession of forestry and became overseers of the training of foresters who managed large forest tracts owned by kings, aristocrats, and the ruling classes. These imported tree reproduction systems have continually evolved and developed into what are now used today. They are separated into classifications and used throughout the world where the practice of forestry and forest management is necessary to encourage sustainable forests. These classifications are conducted in logical sequence and the steps lead to healthy, well-stocked forests for future generations. The Classification of Tree Reproduction Methods Although there are innumerable combinations, for simplification we will list the six general reproduction methods listed by silviculturist D.M. Smith in his book, The Practice of Silviculture. Smiths book has been studied by foresters for decades and used as a proven, practical and widely accepted guide at the point where a timber harvest is necessary and where natural or artificial regeneration is the desired replacement. These methods have traditionally been called high-forest methods which produce stands originating from a remaining natural (using a high or aerial) seed source. The clear-cutting method is one exception where artificial planting, vegetative regeneration or seeding is necessary when the cut area limits complete reproductive tree seeding. Methods to Use When Even-Aged Management Is Preferred The Clearcutting Method - When cutting all trees and removing the entire stand that lays bare the ground, you have a clearcut. A clearing of all trees should be considered when residual trees are starting to lose economic value, when biologic over maturity leads to decadent stands, when the purity of a stand is compromised by cull and lower value trees, when the coppice method of regeneration is used (see below) or when disease and insect invasions threaten the loss of a stand. Clearcuts can be regenerated either by natural or by artificial means. To use a natural regeneration method means you must have an available seed source of a desired species in the area and a site/soil condition advantageous to seed germination. If and when these natural conditions are not available, artificial regeneration via nursery seedling plantings or prepared seed dispersal must be used. The Seed-tree Method - This method is simply what it suggests. Upon removing most of the mature timber, a small number of seed trees are left singly or in small groups to establish the next even-aged forest. In effect, you are not dependent on trees outside the cutting area but must be concerned about the trees you do leave as the seed source. The leave trees should be healthy and able to survive high winds, produce viable seeds prolifically and enough trees should be left to do the job. The Shelterwood Method - A shelterwood condition is left when a stand has had a series of cuttings over the period between establishment and harvest, often called the rotation period. These harvests and thinnings occur over a relatively short portion of the rotation by which the establishment of even-aged reproduction is encouraged under a partial shelter of seed trees. There are two objectives of a shelterwood cut - making ground space available by cutting trees of lowering value and using trees increasing in value as a seed source and for seedling protection as these trees continue to financially mature. You are maintaining the best trees to grow while cutting trees with a lower value for new understory seedling space. Obviously, this is not a good method where there will be only intolerant (light-loving tree species) tree seeds available to regenerate. The sequence of this particular method should be ordered by first making a preparatory cutting which prepares and stimulates seed trees for reproduction, then a seed tree cutting to further open vacant growing space for seeding; then a removal cutting which frees the established seedlings. Methods to Use When Uneven-Aged Management Is Preferred The Selection Method - The selection harvest method is the removal of mature timber, usually the oldest or largest trees, either as single scattered individuals or in small groups. Under this concept, the removal of these trees should never allow a stand to revert back to an even-age. Theoretically, this style of cutting can be repeated indefinitely with adequate wood harvest volumes. This selection method has the widest variety of interpretations of any cutting method. Many conflicting objectives (timber management, watershed and wildlife enhancement, recreation) must be considered and managed differently under this scheme. Foresters know they are getting it right when at least three well-defined age classes are maintained. Age classes are groups of similar aged trees ranging from sapling-sized trees to intermediate sized trees to trees approaching harvest. The Coppice-forest or Sprout Method -Â  The coppice method produces tree stands that originate mostly from vegetative regeneration. It can also be described as low forest regeneration in the form of sprouts or layered branches as opposed to the above examples of high forest seed regeneration. Many hardwood tree species and only a very few coniferous trees have the ability to sprout from roots and stumps. This method is limited to these woody plant types. Sprouting tree species respond immediately when cut and sprout with exceptional vigor and growth. They outpace seedling growth by far, especially when cutting is made during the dormant period but may suffer from frost damage if cut during the late growing season. A clear-cut is often the best cutting method.

Business environment - Essay Example International trade is a significant representative of Gross Domestic Product in many countries. International trade has social, economic and political benefits and these have been realized in most industrialized countries in the recent times. Other factors that have contributed enormously to the development of the international trade are globalization, advanced transport systems around the world, emergence of multinational corporations and practice of outsourcing by many countries. In general, international trade is globalization and it is a branch of economics. When economics is incorporated into international trade, a larger branch called international economics is formed. Foreign Direct Investment has contributed greatly to international trade. This type of trade occurs when an investor acquires an asset from a country other than their own with intentions of managing the property. FDI has been categorized into three classes namely: Equity capital - this refers to the value which a multinational corporation has invested in shares of an enterprise in a foreign country. It includes both mergers and acquisitions and Greenfield investments made by the multinational company in a foreign country. Reinvested earnings- This represents the value of shares that Multinational corporations have invested in affiliate earnings as dividends. The retained profits by the affiliates are assumed by the multinational company to be reinvestment in the affiliate. This can represent up to 60 per cent of outward FDI in the United Kingdom. It is imperative for countries around the world to engage in bilateral FDI arrangements due to enormous growth in institutional, economic and legal interlinkages between countries. FDI has boosted economy all over the world. There is increment in the annual global flow of around $250 billion as experienced between 1985 and 1995. United

It is a broad observation that modern day buildings are more susceptible to maintenance as compared to older counterparts. This research investigates of the impact of design defects on maintenance through their barriers and limitations of the interaction between them in an attempt to improve building design to reduce maintenance costs, especially in hospital buildings. In addition to literature studies, the interviewee questions and a case study have been analyzed to identify design and maintenance defects, their impacts on the maintenance and management of hospital buildings in Saudi Arabia. Furthermore, it explores the concerning roles, responsibilities, obligations, and liabilities of the agents who are involved in the design and maintenance performance and feasible solutions. The King Fahad Hospital was chosen for the stud y and the five interviewees were interviewed on telephone. Qualitative methodology was selected to collect data for this study; it has been found out that the majority of maintenance dilemmas in the hospital building are attributed to design defects. The defects affecting the maintenance of hospital in the budget were led to depletion of maintenance budget besides an increase in maintenance costs. Some recommendations were provided. Conclusion The first topic the chapter reviewed was maintenance. Common problems were identified and approaches to reduce the burden of maintenance through Total Quality Management of design were described. The effect poor design has on society was explored in terms of political, economic, social, technological, environmental, and legal aspects. The chapter discussed design defects in terms of the professional obligations that each agent in the design team holds. The chapter emphasized the roles, which the civil engineers, the architects, the interior de signers, the commissioning agents, and the structural engineers have in the designing process. It also talked about the increasing role of legal action in poor design. Then the chapter discussed the inherent limitations of the building design and maintenance and its limitation in their relation. It lists the scope of the projects as well as the objectives and concludes with the significance of an investigation of the impact of design on the maintenance of hospital buildings in Saudi Arabia. This presents an opportunity for investigations of the impact of design imperfections on maintenance. In prior knowledge of most results and the factors that influenced the maintenance of negligence in design, circles many aspects such as specification of materials, thermal movement, wet areas, ventilation, inefficient detailing, improper material selection and poor design for accessing maintenance measures. The chapter also argued that the design process must also be considered from legal standp oint and the obligations of the design agents. There is mention in the literature of maintenance issues in Saudi Arabia. Ikhwan and Burney (1999) pointed out the importance of maintenance in the Kingdom, and discussed the need for maintenance education. They also highlighted research activities on maintenance performed at King Abdulaziz University in Jeddah. They recommended an extensive assessment of the current states of maintenance management and

Theories of How Individuals Interact in Groups in HSC

Theories of How Individuals Interact in Groups in HSC 2.1 Write an assay explaining theories of how individuals interact in groups, particularly applying them to teams that work in your Health and Social Care setting. The relationship between classical Grounded Theory (Glaser, 1978; Glaser Strauss, 1967) and the interpretive tradition of Symbolic Interactionism is strong and historical. Although this relationship has been discussed in previous publications as a given limited literature has explained the connections between their silent assumptions and concepts precisely and thoroughly (Chenitz Swanson, 1986; Crotty, 1998; Speziale Carpenter, 2007). Bruce Tuckman (1965) developed a 4-stage model of group development, this is his theory on how Health and Social Care professionals should be working effectively in managing human resources. The four stages of his theories are; Forming, Storming, Norming and Performing and also added a fifth stage of model to group development after 10 years which is Adjourning. The fifth model is when a professional breaks the knot and leaves the group without informing anyone. Forming: The group comes together and gets to initially know one other and form as a group. Forming is when a new set of Health and Social Care professionals are introducing one another by communicating and interacting in a group. They exchange information and set a target to be met as successful team work. The manager will need to set a clear guild to the Health and Social Care workers and it must be followed effectively so the colleagues avoid any misbehaviours and prevent from problems arising between each other in a team work. Forming is where a big group of Health and Social Care professionals are depending on one particular individual whom is a team leader or their role model, this person will have a huge responsibility in guiding the group of Health and Social Care professional to the right path in their carer to pass their activities. An agreement on team aims other than received from team leader. In this team individuals are not certain of their own role or responsibilities as they are all depending on one person who is the team leader. The team leader has skills and knowledge and must be willing to answer all the questions about the team purpose, activities and external relationships. Individuals test tolerance of system and leader directs to telling mode as he is in charge of the team and tells everyone to do what he wishes. Storming: A chaotic vying for leadership trialling of group processes. Storming is when a group of members dont agree with each others decisions, team members attempt to establish themselves in relation to another member in the team or team leader, who might receive challenging behaviour from a team member in disagreeing with decisions made. At this stage issues are developed over members having their own views rather than a whole team agreeing to one point of view. A team will only have conflict rising when they are not working effectively and the team leader is managing the group following the guild lines.   The improvement guide: a practical approach to enhancing organizational performance (GJ Langley, RD Moen, KM Nolan, TW Nolanà ¢Ã¢â€š ¬Ã‚ ¦ 2009 books.google.com). Norming: Eventually an agreement is reached on how the group operates (norming) The third step, norming, is where the team members fall into agreement over the solutions for their team. In this step, the team members are able to talk openly about their opinions and have the ability to adjust their behaviour to avoid conflict. The team members agree on the teams values, rules, professional behaviour and methods of work (Armstrong, 2006). Performing: The group practices its craft and becomes effective in meeting its objectives. The final step, performing, is where the team fully understands, co-operates and supports one another, thereby working as a single unit rather than individuals. Teams that have reached this step display high levels of motivation, knowledge, competence and autonomy (Armstrong, 2006) Adjourning: The process of without informing the group, that is, letting go of the group structure and moving on. This is the fifth and last step Bruce Tuckman (1965) developed which breaks the team apart without any signals showing. References Aldiabat, Khaldoun M; Le Navenec, Carole-Lynne.

Ethical Principle Essay

Ethical principles have a huge portion in the impact of intentional or assisted euthanasia. Beneficence according to Beauchamp states, â€Å"compassion; taking positive action to help others; desire to do good; are core principle of our patient advocacy† (Beauchamp,2009,p38). The value of beneficence simply states to do good to achieve the best possible outcome. For example, medical research is expanding and exploring numerous cures for diseases that are causing harm to people. Doctors that are approving euthanasia are because of empathy and kindness for the patient. The doctors and physicians are trying to do good for the patient by performing euthanasia because they know the prognoses is poor and the medical treatment won’t cure the disease. Utilitarianism theory can also be applied to the situation, â€Å"this theory supports what is best for most people. The value of the act is determined by its usefulness, with the main emphasis on the outcome or consequences†(American Nursing Association). In other words, the greatest value for all, is the selection that is morally accurate. For example, some patients support active euthanasia because it ends the suffering of the person. The choice to end life in return brings the great happiness for large amount of people. The autonomy theory states, â€Å"Agreements to respect right to self determine is a course of action and support of independent decision making†. (Beauchamp,2009 p.38). People should have their own choice to make decision for themselves when it involves their life’s. If the member is unable to make his or her needs known, an inform consent or power of attorney should be made before hand of the patient wishes. The ethical theory such as deontology mentions, people should abide to their task and obligations when review an ethical dilemma. Reference Beauchamp, T. L., & Childress, J. F. (2009).

Analysis Of Aldous Huxley s Brave New World - 1591 Words

Independance and self-awareness is an important part of our society, without it, people lose sight of who they genuinely are. Today’s society relies on people doing their duty to work together, like another cog in a machine. It is easy to find oneself feeling insignificant in terms of an independent person, and because of this, people have to actively find ways to keep ourselves occupied. Aldous Huxley was born July 26, 1984. His father was a scientist that helped to develop the theory of evolution. Science was obviously a large part of his life and was most likely a key source of inspiration for his book. In Aldous Huxley’s Brave New World, Individualism is a rarity and society is structured to serve a higher class of people. Society is†¦show more content†¦However, when people are developed on an assembly line, it removes the uniqueness of being a human. Every embryo is developed to fit a certain criteria and perform specific tasks for the higher classes. Sin ce World State is developing everyone through a test tube it removes mothers and natural birth out of the equations. There is a distinct bond between a parent and their child, not only does this help the child grow into a mature adult but it also helps them develop the necessary skills required to work and interact with other people. Furthermore, World State separates each person into a class, Alpha through Epsilon. This segregation prevents people from developing attachments and the attachments themselves are thoroughly discouraged, as Beckham mentioned: â€Å"A world in which the traditional family -in fact, any family at all- has been vilified and rendered taboo† (Beckham 68). World States has taken the human development process even further by conditioning each class to act in a specific manner. By doing so, they are removing the family and free will aspects out of people. Starting from an early age, people are taught to like certain aspects of life and to dislike others . This prevents people from getting curious about the other classes and being content with their own lives, as Mr. Foster says â€Å"We also predestine and condition. We decant our babies as socialized human beings, as Alphas or Epsilons, as
