Mount Lofty Range Birds The native woodlands that once covered the Mount Lofty Ranges landscape has been reduced to about one-tenth of their former extent. This loss of habitat is currently affecting our woodland. A total population size of five-hundred is more than likely to become extinct. twenty more species will eventually disappear about one hundred and twenty almost fifty would eventually become extinct in the Mount Lofty Ranges. This dramatic loss of habitat has devastating implications for many native birds that depends on it for survival of those still found. There are many effects on these birds, one of them is that many of the birds are dying off. The birds in the Mount Lofty Ranges are affected by the loss of habitat, that they
The Pacific Northwest is perhaps most commonly known for its awe-inspiring old growth forests that have been gracing the land for hundreds and hundreds of years. The land in British Colombia, Canada, Washington state, Oregon, and parts of Northern California are the only areas in the world where these forests exist. One of the most unique and amazing inhabitants of this age-old forest is the Northern Spotted Owl. The Northern Spotted Owl has been on the endangered species list for over ten years now. The Northern Spotted Owl can only be found in these old growth forests. The northern spotted owl requires many acres old forests to survive, due to its scarce food supply. They are very sensitive to their habitat, and simply cannot survive in any other environment. These owls, as well as the forests have been disappearing at an alarming rate due to the immense logging industry in its area.

John Updike’s poem “The Great Scarf of Birds” expresses the varying emotions the narrator experiences as he witnesses certain events from nature. His narration of the birds throughout the poem acts as numerous forms of imagery and symbolism concerning him and his life, and this becomes a recollection of the varying emotional stances he comes to terms with that he has experienced in his life. These changes are so gradually and powerfully expressed because of a fluent use of diction and figurative language, specifically symbolism and simile, and aided by organization.
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.
The Northern Spotted Owl can only live in old growth environment, it is considered an “indicator species”: The health of the Northern Spotted Owl population indicates the health of the old-growth forest ecosystem. An individual Northern Spotted Owl needs more than 3,000 acres of old growth to survive, because of its scarce food supply. The Northern Spotted Owl is found in the cool, moist woodlands on the Pacific Northwest. The habitat of the Northern Spotted Owl can be described as trees relatively large in diameter in the stand, multi-layered canopy, large tall live trees with cavities, broken tops, mistletoe, or platforms of branches capable of holding accumulated organic matter suitable for use as a nest, dead standing trees and fallen decayed trees to support abundant populations of prey species, especially northern flying squirrels and woodrats.
I have chosen to do research on the Northern Spotted Owl for my keystone lab. Many factors can influence the life of this species. The Northern Spotted Owl is said to be located in the Old Growth Forests of Northern California, Oregon, Washington and some small areas in British Columbia, and Canada. The northern spotted owl has inhabited these areas for hundreds of years, yet was only found as a species in the early 1900’s. We are all aware the Spotted Owls (Strix occidentalis caurina) is a keystone species, but it is also known as an indicator species of Old Growth Forests. Thanks to the constant need for lumber from timber companies, the Northern Spotted Owl has been steadily moving towards an eventual extinction. ("Northern Spotted Owl.")
Many animals depend on different environments such as lakes, oceans or the forest in order to survive. However due to human intervention such as pollution of the ocean, or heavy deforestation, many animals are at the risk of extinction. One such example is known as the Gundlach Hawk which due to deforestation is currently on the endangered species list. Due to it being on the list, conservation attempts are being made in order to keep the animal alive and save it from extinction.
direction, the major problem for their decline would have to be remedied – loss. of the habitat of the sailor. This fact combined with the owls' short life expectancy and late age. breeding only exacerbates the problem. When loggers remove old growth owl loses habitat for its food, housing, as well as protection from predators.
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.
Mount Rainier is home to many species of birds. Depending on the elevation of the mountain determines what birds you will see. At the lowest area of the park which is characterized by Douglas-fir, and western hemlocks. In this zone you would find northern spotted owls, and marbled murrelet. The next zone of the park is characterized by western white pine, and Pacific silver fir. There can be many different birds in this zone depending on the vegetation, weather, and breading time. The elevation zone of the park is characterized where the Paradise and Sunrise areas are located. This zone is characterized by mixed forest and subalpine meadows. The trees are mostly mountain hemlocks, Alaska yellow cedar, and white bark pine. The Northern spotted owl is the only bird s...
The piping plover, a bird now going extinct, was once very bountiful. When an animal is going extinct, it could mean a lot of things. The Piping Plover is an endangered species. An endangered species is a name for a plant or animal that is slowly dying out. This bird is experiencing population drops, so it is called endangered. It is known to scientists as the Charadrius Melodus (ES: Piping Plover). It mainly resides around the Great Lakes and sometimes lives along the Atlantic coast in Canada and the United States (Piping Plover Page). Piping plovers are sometimes found in Alberta as well (ES: Piping Plover). People used to hunt this bird for sport, or for it’s feathers, which was a leading cause of its dramatic decline in population (Piping Plover Page). Piping plovers always return to the spot in which they were born, and find females to breed with (Piping Plover Page). They woo the female, and mate with her, producing eggs. Many efforts are being made to maintain, and increase the population of this struggling bird, and so far, they have maintained the species very well.
Spotted owl populations are rapidly decreasing because of the barred owl invading its land, and scientists are rushing to find a viable solution. In states such as California, Oregon, and Washington, spotted owl populations have decreased drastically, and scientists are working rapidly to try to find solutions. These researchers have tiringly studied the habitat and livelihood of the owls, and are determining whether the barred owls are responsible for this drop in population and habitat area. Scientists have tried to find different solutions, but there is controversy on which method is best to deal with this imposing problem. The barred owl threatening the spotted owl is a crisis in the West that needs to be solved, and the
The world today is faced with a huge problem; the problem of disappearing forests and associated habitats. While global warming is on the rise due to higher levels of greenhouse gases being emitted all the time from large-scale industrialization and to accommodate the never-ending expansion of the world population, the depletion of the CO2 absorbers, trees and plants, is also to blame. Hundreds of species of animals and plants are going extinct, while many are being recorded down in the list of endangered/protected species every year. Sundarbans is one of the biggest examples of human exploitation on forests and its flora and fauna in the world. This amazingly diverse and resource-rich ecoregion was declared a reserved forest
Due to the continues actions of cutting down these natural habitats the animals were forced to displace to other untouched lands, further up the mountains or traveling to further distances. Indigenous animals that have been greatly affected by deforestation are the tamaraws, wild buffalos. They have been forced to move up further into the forests clinging to the last remaining cluster of trees on the mountains. The population of this animal have drastically decreased throughout the years and are now classified as endangered animals, “from the population of about 10,000 around 1994, only 250 tamaraws remain on the island today (Walpole, 1993).” It has been predicted that the survival of the tamaraws is unlikely if the deforestation continues.
Birds have direct and indirect economic and cultural values for people. Birds are important for a lot of reasons. Birds provide us food, medicine, fertilizers and also bring about pollinations. They are important because they are a part of the food chain. Birds are also important because they help spread seeds around and thus help with the planting process. Birds also perform vital ecological role, besides their economical role. They are critical links within the fast food chains and webs that exist in the ecosystem. The economic importance of birds can be studied into two parts – A) Beneficial effect B) Harmful effect.
