Corridor Analysis

The United States is centered on the economic development, more specifically on the creation of wealth. It is understandable that creating wealth is of great importance, but continued economic development has lead to degradation of our environment. Therefore, presently we need sustained economic development in conjunction with responsible environmental and resource protection. As development increases, natural linkages within the landscape continue to be fragmented and remnant natural habitats become isolated. As a result, we need strategies to fight the consequences of fragmentation. One such strategy is to create a network of corridors. Corridors are narrow, linear strips of habitat that have wildlife value.

In “New Initiatives for Wildlife Conservation” Larry Harris and Peter Gallagher (1989) state, “Our refusal to incorporate movement across human dominated landscapes into our conservation strategies has made luck the chief prerequisite for survival in highly populated areas.” Corridors provide ecological and environmental quality values. For one thing, they help to maintain biological diversity. Fragmenting landscapes into distinct patches and restricting wildlife increase the risks of movement, and can also have severe consequences for the conservation of biological diversity. Conservation of biological diversity is extremely important because it can reduce the thread of a species becoming endangered or extinct. Corridors help to sustain the biological diversity by preserving migration corridors and connecting fragmented centers of plants and organisms.

Harris and Gallagher conclude that “Habitat connectivity declines with human modification of the landscape and the use of corridors is an attempt to maintain or to restore some of the natural landscape connectivity.” As a result, a network of corridors can improve fragmentation of the landscape and habitats. Corridors can serve as habitats in their own right and they can also serve as linkages for animals that migrate from patch to patch.

There are many different types of landscapes that can function as corridors. A stream corridor is perhaps the best area to create a system of interconnected corridors. The interface of land and water represent some of the richest wildlife habitats.

  • Urbanization & Habitat Loss in the Fraser Valley as a Threat to Biodiversity

    1867 Words  | 4 Pages

    We don’t often stop to consider the impact that simply living our human lives has on the other species that once called our neighbourhoods their home. The Fraser Valley, “one of the most important and complex ecosystems in the country” (Thom, p. 171), has been dramatically altered to make a more convenient landscape for housing and farming. In this process, critical habitat has been destroyed and many species that were once abundant have disappeared from our area (Cuthbert p. 24). Urbanization is ongoing and is thought to be the most significant threat to the incredible biodiversity found throughout British Columbia, and particularly the population-dense Lower Mainland (Harding, p. 355). Biodiversity, the “complex web that sustains life on this planet” (Austin, et al., p. 5), is vital for our survival as humans (Cuthbert p. 74). Any loss of biodiversity affects the entire ecosystem and all organisms within it (Fetene et al., p. 52). In the quest to house the ever-expanding human population, we must also consider habitat conservation and seek to preserve the rich biodiversity found in the Fraser Valley that supports and enriches our lives.

  • Lee Hamilton's Public Criticisms Of Congress Still Doing Their Job?

    1323 Words  | 3 Pages

    Hamilton provides an inside look at how congress really works and clears up popular misconception that make members of congress look like wasteful bickering crooks that support gridlock and are only concerned with the needs of interest groups and lobbyists. Hamilton argues that Congress has changed for the better throughout the years and that they are held at higher standards than they were before. Hamilton states that Congress is not only working at keeping the public happy but that have recently become faced with a lot more issues than before, they are not only more issues but more complicated and technical that are very high risk policies that take a long time to produce a decision (Hamilton, 1988, 65). Hamilton states that Congress is a system in which the viewpoints of everyone are taken into account and make sure there is a consensus when it comes to defining decisions. Even though many of us acknowledge that lobbyist and special interest groups play an essential role in the law making party, Congress is making an effort to make sure that everyone’s voice is heard. Congress is making sure that the balance of power is distributed properly. In recent years, there has been a decline in mega-lobbies and interest groups so that not only the wealthy powerful get their voice heard, but the everyday american people get an opinion in things that affect them as well. In Gary Lee’s article, The NRA Has Lost some Firepower, we can see that interest groups are beginning to have less of an influence on larger political decisions (Hamilton, 1988, 65). For example, the National Rifle Association’s defeat in the battle over the “Brady bill” and their war towards trying to revamp Medicaid was a great loss for lobbyists and

  • Police Brutality: A Stain on American Society

    1744 Words  | 4 Pages

    Police brutality remains one of the most serious and divisive human rights violations in the United States. The excessive use of force by police officers persists because of overwhelming barriers to accountability. This fact makes it possible for officers who commit human rights violations to escape due punishment and often to repeat their offenses. Police or public officials greet each new report of brutality with denials or explain that the act was an aberration, while the administrative and criminal systems that should deter these abuses by holding officers accountable instead virtually guarantee them impunity (Williams 45).

  • Bandicoot Observation

    521 Words  | 2 Pages

    Due to human activity, the natural fauna of the world is becoming displaced; this is especially profound in terrestrial mammalian species. This study specifically looks at fragmented land affecting the northern brown bandicoot, Isoodon macrourus, in the city of Brisbane, Australia. The experiment was conducted using mark-recapture methods and radio tracking in order to distinguish bandicoot home ranges, densities, and habitat. It was observed that the bandicoots sheltered during the day in areas with tall, dense grasses and weeds and exhibited nocturnal foraging in urban lawns and recreational areas within small ranges. The study suggests that the grass and weeds provide an ideal habitat for the bandicoots, allowing them to thrive in large populations.

  • Keystone Species

    2169 Words  | 5 Pages

    Keystone species maintain ecological communities by providing structure and balance for their habitat. The concept behind a keystone species is that they support species diversity through their presence, activities and abundance within the community (Mills et.al. 1993). If a disturbance happens within the community and the keystone species disappears, the organization and diversity drastically shifts. To be defined as a keystone species, there are a few characteristics a species must demonstrate. The first is that their presence within the community must help structure and assist the diversity of their community (Mills et.al. 1993). The second is that they must have some importance to their community in relation to the other species who live there (Mills et.al 1993). The keystone species are at the top of the community structure, with few, if any, predators. They control the population density of the primary consumer who consumes the primary producer (Mills et.al. 1993). Sea otters, which typically live in tidal areas off the western coasts of the United States and Alaska, are a common example of a widely studied keystone species.

  • Adverse Impacts of Landscape Fragmentation on Biodiversity

    2246 Words  | 5 Pages

    Landscape fragmentation contributes to loss of migratory corridors, loss of connectivity and natural communities, which all lead to a loss of biodiversity for a region. Conservation of biodiversity must include all levels of diversity: genetic, species, community, and landscape (CNHP 1995). Each complex level is dependent upon and linked to the other levels. In addition, humans are linked to all levels of this hierarchy. A healthy natural and human environment go hand in hand (CNHP 1995). An important step in conservation planning, in order to guarantee both a healthy natural environment as well as a healthy human environment, is recognizing the most endangered elements.

  • We Must Stop Police Brutality

    835 Words  | 2 Pages

    According to the National Police Academy, in the past year, there have been over 7,000 reports of police misconduct; fatalities have been linked to more than 400 of these cases (Gul). Police brutality is often triggered by disrespect towards the police officer. The most noticeable form of brutality is physical, where Chemical gas, batons, tasers, and guns, can be used for physical intimidation or to actually hurt people. Police brutality can also take the form of verbal abuse or psychological intimidation. It seems reasonable to understand that sometimes the police are put into situations where excessive force may be needed. But, because some officers use these extreme actions in situations when it is not, police brutality should be addressed and looked into by both the police and the public. For instance, a police officer who beats a nonviolent protester with a baton would probably be accused of excessive use of force, under the argument that the police officer probably could have dealt with the situation less violently.

  • Essay On Keystone Species

    1352 Words  | 3 Pages

    A keystone species is a species that’s whose impact on its community or ecosystem is larger and greater than would be expected from its relative abundance or total biomass in the environment. The presence of keystone species maintains higher species diversity in ecosystems than if keystone species were absent. The role that a keystone species plays in its ecosystem is analogous to the role of a keystone inane arch. While the keystone is under the least pressure of any of the stones in an arch, the arch still collapses without it. Similarly, an ecosystem may experience a dramatic shift if a keystone species is removed, even though that species was a small part of the ecosystem by measures of biomass or productivity. It became a popular concept in conservation biology. Although the concept is valued as a descriptor for particularly strong inter-species interactions, and it has allowed easier communication between ecologists and conservation policy-makers, it has been criticized for oversimplifying complex ecological systems.

  • Law School

    1220 Words  | 3 Pages

    Perhaps one of the most difficult aspects of the practice of law is learning to be a lawyer. Virtually every new lawyer today is a graduate of law school, a much dreaded, but fulfilling journey to practicing law. Modern law schools differ greatly from their earlier counterpart, in that many more requirements and responsibilities exist. In colonial times, students pursuing a career in law would enter institutions for instruction of the law, and would automatically become qualified to practice law in the courts after a few years of study. Today, however, becoming a lawyer takes much more training, rigorous work and effort, and many years of studying in order to take a bar exam of which passage represents qualification. There is much more consideration concerning who is admitted, what kind of curriculums are taught, how exams are offered, what kinds affiliation exist, how much law schools differ from one another, and what it ultimately takes to be fully competent as a practicing attorney.

  • Importance Of Wildlife Essay

    1290 Words  | 3 Pages

    One of the most important aspects in life is protecting the wildlife. The wildlife drives the earth’s biodiversity. Biodiversity is the diversity, or variety, of plants and animals and other living things in a particular area or region. Without biodiversity there would be nothing on the earth. One of the important aspects of biodiversity is that each species of vegetation and creature play a particular role of the circle of life. Protecting their food, shelter, oxygen and soil enrichment will keep the ecosystem thriving. Our society created many different ways of keeping the wildlife and animal populations up to par. Habitat management and population management are necessary to controlling the population of game animals and fish, and take a big part in protecting the habitat they live in.

  • Phoaching Of The Sumatran Tiger

    This method is effective because tiger corridors are successful in increasing the connectivity between national parks, but evidence also suggests that they are important for breeding with evidence of tiger cub tracks within the corridor. Another importance is the use of the corridor as home territories with evidence collected from the Tiger Conservation and Protection Unit for the Fauna and Flora International Sumatran Tiger Project [7] shows the importance of reducing the fragmentation of tiger habitat using tiger corridors. I would suggest this data is valid and reliable because the programme is lead by Joe Smith PhD who has a Master’s Degree in Wild Animal Biology from the Vetinary College and Institute of Zoology in London. His experience and education ensures that this project would be carried out correctly and the results would be both valid and reliable
