Cork oak, Quercus suber, is native to the Woodland Biome located in the Mediterranean. These cork oak forests are common in such mediterranean countries as Portugal, Spain, Algeria, Morocco, Tunisia, Italy, and France. Known for its high species diversity, the cork oak is one of 13,000 plant species found only in this Mediterranean Woodland (Cork Screwed? 2006). In fact, the mediterranean has the second highest level of species diversity, aside from the tropical Andes. As we know, ‘diversity begets diversity’, and this high level of plant diversity allows for a high level of animal diversity as well. Endemic to this Mediterranean biome include spiders, geckos, skinks, the Iberian Lynx, the Iberian Imperial Eagle, Barbary Deer, Cinereous Vultures, and Black Storks. Many of these species are either threatened or endangered species found only in the Mediterranean cork forests (Cork Screwed? 2006). Besides serving as the sole habitat for many species, cork forests also serve many other important functions. For one, these forests, found near the Gibraltar Straits, act as a kind of rest stop for the many migratory birds traveling from western Europe (Cork Screwed? 2006). These forests also prevent any possible landslides or erosion that could occur on the steeply sloped forest hills by anchoring their roots deep into the soils. Their deep roots also help transport nutrients from deep underground to the upper soil levels for the short rooted herbaceous layer. Their treetop canopy also protects the soil from water erosion by intercepting much of the rainfall (Cork Screwed? 2006). Another important value of cork trees is their ability to absorb carbon dioxide and thus reduce the amount of greenhouse gases in the atmosphere. In fact, wh... ... middle of paper ... ...k 2012). Unlike many other of our environmental crisis, this in one that can be solved on a consumer level and does not rely solely on the backs of big companies and distant governments.

Forests cover 31% of the land area on our planet. They produce vital oxygen and provide homes for people and wildlife. Many of the world’s most threatened and endangered animals live in forests, and 1.6 billion people rely on benefits forests offer, including food, fresh water, clothing, traditional medicine and shelter (drug war facts, Page 1).
Westfields, a medium sized wetland region, is located on the outskirts of Limerick city and within the floodplain of the River Shannon (CAAS (Environmental Services) Ltd., 1999). Wetland regions are broadly defined within the Ramsar Convention (1971, 1), as, “areas of marsh, fen, peatland or water, whether natural or artificial, permanent or temporary, with water that is static or flowing, fresh, brackish or salt including areas of marine water, the depth of which at low tide does not exceed six metres.” Identified as some of the most diverse habitats on earth, wetlands are also under severe threat, with a “10% decrease in their area occurring worldwide between the years 1990 and 2006” (CORINE, 2006). Westfields is no exception. Known worldwide for the diverse flora and fauna, in particular avifauna, that are present, the area has seen a dramatic decrease in size from its traditional expansive domain to a present area of twenty-six hectares. Thus, this essay aims to examine in detail the biogeographic merits of these declining wetland regions in particular Westfields, record the current condition of this particular wetland, and explore potential ideas for future conservation.
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...
One of the most predominate ecosystems is the forest community. Covering about one-fourth of the land area on Earth, forests consist mainly of trees and other woody vegetation, growing closely together. The trees can be large and densely packed, as they are in the coastal forests of the Pacific Northwest, or they can be relatively small and sparsely scattered, as they are in the dry tropical forests of sub-Saharan Africa. Forests are complex ecosystems that also include “soils and decaying organic matter, fungi and bacteria, herbs and shrubs, vines and lichens, ferns and mosses, insects and spiders, reptiles and amphibians, birds and mammals, and many other organisms” (Audesirk, 2003). All of these components constitute an intricate web with many biological interconnections. A bird may depend on the upper branches of a tree for nesting, while the tree may depend on the fungi surrounding its roots to obtain water and nutrients. A forest performs a number of vital environmental services, such as cleansing the air, moderating the climate, filtering water, cycling nutrients, providing a habitat for animals and provides humans with recreation and beautiful scenery. Resources from the forest supply raw materials, such as lumber, paper products, greenery and pharmaceuticals. Some of the developing issues today concerning forests are fires and what we as a society can do to restore the natural ecosystems within the forests around our world. Many aspects are to be considered when looking at the ecology and bioremediation of forests such as, human activities, wildlife, endangerment and environmental changes. This paper will discuss the effect wildfires have on the forest ecosystem.
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)
Over the past two centuries, the human population has become increasingly prosperous; nourishment has improved, the economy has developed and longevity has increased. From this, it is possible to conclude that man’s battle with nature is proving beneficial. However, the wellbeing and success of mankind greatly relies on ‘ecosystem services’, which comprise any benefits provided by ecosystems that contribute towards human life. These developments in wellbeing have partly been achievable because of the increased exploitation of these ecosystem services.
• Dendroecology: The use of tree rings to study changes in ecological processes over time such as defoliation by insect outbreaks; the effects of air, water, and soil pollution on tree growth and forest health; the age, maturity, and successional status of forest stands; and the effects of human disturbances and management on forest vitality.
Rainforests once covered 14% of the worlds land surface, however now it only covers a mere 6%. It is estimated that all rainforests could be consumed in less than 40 years. Trees are becoming more needed and used everyday. We need them cut down for many reasons such as paper and timber, while also needing them ‘untouched’ for other reasons like oxygen, we have to ask ourselves, which is more important? At the current rate, most of the rainforests are being cut down for resources like paper and timber, but less importance is being placed on main resources like oxygen.
...huge global problem, caused by human waste, but which can be solved by going green and reducing human impact on the environment.
Every day when looking out a window, people see a beautiful earth. The earth is intriguing, but hinges on a delicate balance. Many natural resources keep the grass green and the sky blue. Man has made quite an impression on our world, and has transformed the earth's resources into tools to make life easy. However, mans' manipulation on earth has become detrimental to the health of our planet and the safety of mankind. Through the use and production of resources such as oil and energy, man is gradually poisoning the earth. Pollution has become such a dilemma in society; there is no real control or a feasible solution to society's recklessness. Without complete change, our system will collapse. The earth will eventually retaliate with disaster, or corporate control of our economy will cause hysteria and depression. Evaluation of the consequences and repercussion of worldwide pollution, may give people a better idea of what the future holds.
In many communities worldwide, people depend on forests, for fuel wood-gathering, harvesting of wood and non-wood forest products, for larger-scale commercial purposes, habitat for more than half the world’s terrestrial species, clean water, and other important ecosystem services (De Groot et al., 2002, Santangeli et al., 2013, Chhatre and Agrawal, 2009). However, the forest biodiversity is continuously undergoing loss which directly or indirectly contributes to forest ecosystems being transformed and in some cases irreversibly degraded. A large number of species have gone extinction or have been threatened to extinctions and reduction in population (Morris, 2010, Kuussaari et al., 2009). The main causes of biodiversity lose are a complex combination of social, economic and natural process, which includes continued growth of human population and per capita consumption, climate change, ocean acidification and other anthropogenic environmental impacts (Butchart et al., 2010, Geist and Lambin, 2002). Currently, the changes in forest biodiversity are more drastic than at any time in human history.
Former Vice President, Al Gore’s speech, The Climate Emergency, was a highly accurate prediction of the circumstances our planet would be under in coming years. The facts relevant as of 2004 are still true in the year 2015. While many companies and individuals have learned to contribute to helping our plant go greener, the dangers of the climate change are still a pressing issue supported by scientific evidence. With occurrences such as extreme weather events, rising sea levels, and ice cap disappearances, global warming is physically being show on our planet and in order to prevent a complete reversed climate on our hemispheres, the population of Earth as a whole must ban together to reduce our carbon footprint.
This persuasive speech was given in Rio de Janeiro, and was a plea to the individuals in attendance at the United Nations Earth Summit to recognize how they are contaminating the environment with hopes that these audience members will revise their future proposals.
The protection of the environment however has just recently become the major issue that it is in today’s society. People worldwide have slowly begun to realize and become aware of the blatant destruction and deterioration of the environment and ozone. As well as the consequences and side affects, that we, as a society have created. The majority of people are just becoming aware of the frightening reality of the situation. As society becomes more informed on the issue of the environment, they too become more impatient, and feel that in the snap of fingers, the damage can be reversed and future damage can be stopped instantaneously.
Many people assume that the environment is not in danger. They believe that as technology advances, we do not need to worry about renewing natural resources, recycling, and finding new ways to produce energy. They state that one person in the world does not make a large difference. In reality, each individual's contribution greatly affects our environment. Our natural resources are slowly disappearing, and we must work together to save them and the Earth from ruin.
