5 Causes of the Death of a Tree
5 Causes of the Death of a Tree Trees have an extraordinary ability to withstand many damaging agents that are ever-present in their environment. Trees have evolved over millions of years to ward off many stressors that bite and burn and starve and rot their roots, trunk, limbs, and leaves. It is amazing how a tree compartmentalizes itself to seal off dead wood and disease, defoliates to reduce the effect of drought and bleeds to extract harmful insects. We know that all trees do eventually die. There are many hundreds of seedlings and saplings that succumb for every mature tree left in the forest. All ages of trees eventually die to the same agents and only the most adaptive (and often lucky) individuals make it to old age. There are 5 factors to which a tree eventually succumbs: death from its environment, death from harmful insects and diseases, death from a catastrophic event, death from age-related collapse (starvation) and of course, death from harvest. In most cases, death is the result of several, if not all of these conditions taking place simultaneously. Lets take a look at each of these. Adverse Environment Ground and site conditions on which a tree lives ultimately determines the environmental stressors placed on that tree. If a drought-sensitive tree lives on a dry site during drought conditions, it may indeed die from lack of water. But that same tree can also be more susceptible to every other life-threatening factor placed upon it. For example, a disease that appears to be killing the tree may in effect be only a secondary issue to the initial environmental problem. Examples of adverse environments to trees are poorly draining soils, salty soils, droughty soils, air and ground pollution, extreme sun heating or cold spots and many, many others. It is particularly important to understand a tree species genetic tolerance to environmental conditions when planting. Many trees adapt very well to poor sites, but you need to understand which species fits where. Harmful Insects and Disease Virulent diseases like Dutch elm disease and the chestnut blight have caused sudden death to entire forests in North America. However, the most common diseases are more subtle in their work, killing many more trees in total than virulent types and cost forest and yard tree owners billions of dollars in forest product and specimen tree value. These common diseases include three bad ones: Armillaria root rot, oak wilt, and anthracnose. These pathogens invade the tree through leaves, roots and bark wounds and damage a trees vascular system if not prevented or treated. In natural forests, prevention is the only economic option available and is a significant part of a foresters silvicultural management plan. Harmful insects are opportunistic and often invade trees under stress from environmental problems or disease. They not only can directly cause tree death but will spread harmful disease fungi from a host tree to surrounding trees. Insects can attack a trees cambial layer by boring for food and nesting cavities, or they can defoliate a tree to the point of death. Bad insects include pine beetles, the gypsy moth, and emerald ash borers. Catastrophic Events A catastrophic event is always possible in a vast forest as well as in an urban setting. All property, including trees, are subject to being damaged or destroyed. In many cases, trees are not killed but are damaged to the point where their vigor is lost, and insects and disease take advantage of a trees loss of resistance. Significant tree losses can occur during a forest fire or when exposed to tornado-strength winds. Trees take a terrible hit when heavy ice is deposited on species sensitive to limb weight which results in breakage. Floods that do not recede quickly can cause root oxygen levels to diminish to the point where tree damage can occur. Extraordinary drought makes quick work of moisture-loving tree species and can harm all trees when extended over a long period. Old Age For trees who beat the odds and live through maturity to old age, there is a slow dying process that may take centuries to complete (in long-lived species). The modular tree compartmentalizes around damage and infected areas and continues to grow. Still, growth starts slowing after a tree matures, the ability of the plant to support itself diminishes and incurs the loss of adequate foliage for hydration and food. New immature branches, called epicormic sprouts, try to assist in maintaining an old trees vigor but are weak and are insufficient to sustain life for very long. A mature tree slowly collapses under its weight and crumbles to become the nutrients and topsoil for future trees. Timber Harvests Well remind you that trees do die to the ax. Trees via their wood have supported humankind and civilization for millennia and continue to be a necessary part of the human condition. The practice of forestry through professional foresters work continually with much success to provide a sustained flow of available wood volume and at the same time, ensure a surplus of trees. Some consider deforestation a growing global crisis.

Teaching and Learning English Essay Example | Topics and Well Written Essays - 2250 words
Teaching and Learning English - Essay Example Teachers and students may often identify the need for vocabulary learning, but fail to employ the techniques that would make the learning really effective, interesting, and easy. "The need for meaningfulness in language learning has been accepted for some years. A useful interpretation of 'meaningfulness' is that the learners respond to the content in a definite way. If they are amused, angered, intrigued or surprised the content is clearly meaningful to them. Thus the meaning of the language they listen to, read, speak and write will be more vividly experienced and, therefore, better remembered. If it is accepted that games can provide intense and meaningful practice of language, then they must be regarded as central to a teacher's repertoire. They are thus not for use solely on wet days and at the end of term!" (Wright et al, 1984). Therefore, the significance of language games in the learning of vocabulary is remarkable. There are various reasons to consider the use of games as effective and advantageous tool for learning and teaching vocabulary which is one of the inevitable aspects of English language learning. ... Third, vocabulary games bring real world context into the classroom, and enhance students' use of English in a flexible, communicative way." (Huyen & Nga, 2003). Treated from the affective aspect of the learning process, a vocabulary game lessens the affective filter and encourages, in the learner, the creative and spontaneous use of language. More importantly, the use of such vocabulary games promotes communicative competence of the learner and motivates him/her in the learning process. By motivating the learner for the continuous use of the language in communication, the vocabulary games help him/her in developing, apart from the learning of vocabulary, language competency as a whole. To judge the vocabulary learning games by the standards of Cognitive Theory of Learning, they reinforce learning activity, thereby, ensuring and affirming the learning to be meaningful and complete. This technique of vocabulary learning reviews and extends the vocabulary competence of the learner and, therefore, finds it very useful tool of language teaching. The modern theories of learning and teaching, affirm the teaching activity to be centered on the student and teaching and learning of English vocabulary through games can be considered the one of the best example of student centered teaching. Like the student centered methods of teaching, in this method vocabulary teaching, the teacher is just the facilitator and the real performer is the leaner. This makes the learner more active in the learning process and he/she learns more effectively. The learning of English vocabulary through games also facilitates the learning procedure to be easy and effective, as the learners are made active by the practice or there is greater possibility for class cohesion.

Washingtons Farewell Address Article Example | Topics and Well Written Essays - 750 words
Washingtons Farewell Address - Article Example From this study it is clear that Washington said that he was never really qualified to be the president of such a huge nation and everything he had achieved during his tenure was because of the support of the public. Washington's primary focus in his farewell address was on the unity of the states and the people. He stressed that the country would only succeed and survive if all the states of the country remain united. He warned the American Public that the safety and prosperity of the nation would always be threatened by domestic as well as foreign elements and unity is their only weapon against these enemies of the nation.This paper outlines that Washing also emphasized on the negativities of sectionalism and voiced his concerns over the creation of political parties. His warning was particularly targeted at the creation of Jefferson's Democratic - Republican Party. He acknowledges the healthy role political parties can play in promoting democracy but he advises them not to create disunity. These political parties can promote democracy and freedom in a totalitarian environment but that does not always happen. He points out that the creation of too many political parties can promote disunity and hamper the functioning of the government.Ã A large part of Washington's farewell address is dedicated to the discussion of foreign policies and their impact on the nation.Ã Washington advised that the foreign policy should be one which promotes 'peace' and harmony.... The Country should always prefer peace over war and fighting on behalf of a friendly nation on an unjust cause would only harm the goodwill of the country and should always be avoided. He is against the formation of permanent foreign political alliances. He argues that permanent alliances especially with the European countries would not be in the best interests of the country. He opines that trade relationships should be promoted without forming political alliances. This would allow the government to remain neutral on the political issues and to have more focus in the internal affairs of the country which would consequently result in prosperity. He shows his support for the newly formed constitutional government. He believes that it is the right of the people to have a say in the functioning of the government but this should only be done through the constitutional amendments. If the American public is against the policies and working of the government, they should turn to constitutio nal amendments rather than rebellion or revolution. This would ensure the proper political and economic functioning of the country. He warns that manipulating the amendments with the intention to overthrow the government could prove detrimental for the country and any constitutional amendment should be made when it is deemed absolutely necessary and after adequate consideration. He also dedicates a small part of his address to talk about religion, education and morality. In his address, he says that moral values play an important role in maintaining justice and public happiness and that morality is interlinked with the religion. And since religion and morality protect and talk about safeguard of live, honour and property, they are important for the public prosperity. He has also

Analysis of Wangero Leewanika Kemanjo (Dee) in Everyday Use
Analysis of Wangero Leewanika Kemanjo (Dee) in Everyday Use Where Must One Fit Analysis of Wangero Leewanika Kemanjo (Dee) in Everyday Use What made the Black Power movement of the 1960s and 70s such a powerful force, and why did it start in the first place? Author Russell Rickford explains in We Are an African People: Independent Education, Black Power, and the Radical Imagination, what Pan-Africanism means. The definition consists of rethinking African-American identity not in terms of being a minority or racial group, but as an African people. The movement was grounded in the importance of cultural rebirth to a people who were deemed unworthy of moral treatment, excluding them from the label of human. They did not know anything nor were aware about their African heritage. In Alice Walkers story Everyday Use she describes two sides of the same coin when it comes to heritage. Maggie, who stays at home with Mama and lives their heritage through traditions which are passed down. And Dee, who becomes enthralled with the concept of African-nationalism, practicing new habits which alter her psyche. This leads Dee to denounc e her recent heritage, excluding Mama and Maggie for being uneducated and categorizing the objects used every day as priceless folk-art. With the fight for desegregation of schools and the civil rights movement of the 1970s, African-nationalism was born. This is the time period when Dee, who was college educated, where the trend originated, had a new-found outlook on her African roots. So much so that she changed her outward appearance and name. When Mama inquired on why she changed it to Wangero Leewanika Kemanjo, Dee simply replied with Shes dead. I couldnt bare it any longer, being named after the people who oppress me.(27) Perplexed by the concept of the name change, Mama told her she was named after her aunt Dicie and that Dee was handed down through the generations. Wangero, getting tired of the conversation, jumped to the conclusion that somewhere down the line her ancestor was a slave to a white family and thus gave her a white name. Many outside sources such as The Nation of Islam encouraged Africans to abandon their slave names, their leader Elijah Muhammed writes You must remember that slave-names will keep you a slave in the eyes of the civilized world today. You have seen, and recently, that Africa and Asia will not honor you or give you any respect as long as you are called by the white mans name. Along with changing her name, Wangeros attire transformed as well. Straight hair, for Africans was a sign, another step towards assimilation into white society. Too more effectively exclude herself as an independent black woman Wangero grew out her afro. To Africans it was a symbol of defiance and repossession of her ancestral identity, embracing who they were naturally without being categorized as undesirable for their lack of straight fine hair.Ãâà She dressed herself in a long flowing bright dress that looked a lot like a traditional African garb and instead of saying hello she greeted Mama with the African term Wa-su-zo-Tean-o. The introduction to the new and improved Dee attests to the psychological process of morally separating herself from the past generations and reclaiming her Blackness. This includes wanting to take items from Mamas house in order to display them in a show and tell way further amplifying what she had to overcome. We are lead to question Dees sincerity when it comes to the acquisition of the items. Mama, our narrator, reminds us on how Dee hated the childhood house they used to live in and was joyful when it burnt down. Dee was embarrassed by Mama and the house, not wanting to bring friends over for introductions. She also tells us that when Dee was first going away to college, she offered her the very same quilts she now wanted to take and cherish. At the time, Dee abruptly refused them claiming they are old-fashioned, out of style. One can argue that the new-found appreciation for the family heirlooms is just part of the trend. That Dee can be seen as falsely affirming herself and becoming manipulated by the movement. Seeing that is it cool to have lived the struggle, that she came through by showing off her heritage through the art of hand stitched quilts made by her aunt. It seems as if she wants to gain respect from others following the movement by hanging and using these objects as art p ieces rather than the circumstances onto why they were made. Furthermore, at the beginning of the story, she snaps a picture of Mama and Maggie on the front porch. This is done after Mama describes herself as a large, big-boned women with rough, man working hands, one of the reasons why Dee never brought anybody over. This is done to further disrespect Dees own childhood, using it as a sort of show and tell, objectifying Mama and Maggie grouping them in the same category as the quilts, perhaps because she has missed out on the struggle of her heritage not learning the traditions of her ancestors. Dee, as Mama has lead us to believe, has never truly fit in. Always having her style even when she was young. Going away to college although has educated her academically, has left her out of learning the skills of her heritage like Maggie has. Quilting, field work, and all things Mama and Maggie have to deal with on a day to day bases is left untouched by Dee. This only solidifies Dees longing to be part of a culture and heritage she may feel left out of.Ãâà She feels obligated to present herself as part of the movement with the objects she wants to display. An African-American woman taking back her black identity. Trying so hard to claim the ranks on the social ladder leaves Dee unfeeling towards Mama and Maggie. This is especially seen when Mama refuses to give Wangero the quilts. Dee storms out to the car saying you dont understand your heritage. Understanding the character of Dee is complex. Because of the time period, Dee seems to be manipulated into a movement. While it is just, Dee resents her childhood forgetting where she came from. This in turn, leads her to denounce her recent heritage, demeaning Mama and Maggie and trying to fit within this movement by displaying folk-art. It is sad to see Dee pitying them as she gets into the car saying to Maggie Its really a new day for us. But with the way you and Mama live youd never know it just for one last verbal stab in defiance of her not getting her way. However, I end up feeling sorry for Dee, for within this new world she is living in, one must have asked the question where do I fit in? Work Cited Christian, Barbara T.

Fairies: Beauty or Contentment? :: English Literature
Fairies: Beauty or Contentment? Fairies- like witches- were widely accepted as real in the Elizabethan era. The witches in Macbeth still stir debate over whether they initiated Macbethââ¬â¢s crimes or simply anticipated then. What role do you think the fairies have in A Midsummer Nightââ¬â¢s Dream? Are they simply a theatrical device to create wonder and beauty on stage or do the fairies have a greater significance? How does Shakespeare use them? In correlation to Shakespeareââ¬â¢s Macbeth, the role of the witches produces a direct connotation with the role of the fairies in A Midsummer Nightââ¬â¢s Dream. The philosophical perception of fate is carried throughout both the dramas, enacting to drive the plot forward. In A Midsummer Nightââ¬â¢s Dream, Shakespeare uses the fairies to depict a magical setting, symbolizing beauty, love and contentment. These symbols form the basis of the play in context to the plot for the reason that these symbols drive the plot to come full circle by the 5th Act. However, the magical setting portrays Shakespeareââ¬â¢s intent of having the interaction between the two worlds; hence the combination is what formulates the plots complications whilst further proving the drama to be a romantic comedy. In addition, A Midsummer Nightââ¬â¢s Dream revolves around the themes of love and marriage; thus the implication of fairies adds to the emotions of content through possessing a magical and joyous touch. Lastly, in contrast to the witches in Macbeth, the fairies donââ¬â¢t seem to possess an evil side, hence signifying the love and romance that surrounds the play. On this basis, Shakespeare uses the fairies to create an ambiance of affection; as their wits disregard the play to be more comedic than tragic. Nonetheless, Shakespeare connects the fairies to comedy within the play for the fact that the characters are in a dream world which frustrated lovers find happiness against all odds through the juice of a tree and further lovers suicides can be laughed at because they are part of badly told tale. In context to the play, the fairies significance is somewhat vital for the reason that their actions and decisions determine the course of the play. Furthermore, the opening scene is somewhat significant for the reason that it tells the reader the play is a fairy story, thus the role of the fairies is then imperative to some extent. ââ¬Å"And then the moon, like to a silver bow new bent in heaven, shall behold the nightâ⬠implies the notion of a ââ¬Ëonce upon a time storyââ¬â¢, hence being a magical tale. Secondly, in correlation to the notion of fate that persists within the real world is determined through the magical droplets of the fairies, hence causing complications and the structure
