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.")
The northern spotted owl is medium in size and is a nocturnal raptor that lives in mature and old-growth forests. Spotted owls hunt voles and flying squirrels in the forests and nest high up in big trees with open spaces. Spotted owls mate for life and live 10 to 15 years. ("Northern Spotted Owl.") For many decades the Northern Spotted Owl has been in danger from the Timber industry. Loggers working for the timber companies do not care if every owl is killed or the last Old Growth Tree is finally cut down, as long as they see a profit from it and not something that will damage their bank accounts. ("Northern Spotted Owl.")
In 1987, when the Endangered Species Act was put into practice, the Federal Wildlife Service refused to list the Northern Spotted Owl. The FWS was then sued by the National Audubon Society to list the Species. During this time period, it was discovered that when examining the Northern Spotted Owl for its listing the FWS had looked at both the economics and the politics in ...

...l keystone includes fungi, Douglas-Fir and the Flying Tree Squirrel. The squirrels eat truffles made by fungi which are of an important tree species. The squirrel then spreads these fungi in the forest by leaving it in its feces. The fungi play a main part in the old growth forests and effect the growth and health of many northwestern trees.

And subsequently, new policies and laws are created to give people equal access to wildlife. The question regard conservation is very much alive today. And United State needs conservation of wildlife. And the Federal department responsible for conservation, department of the interior are under attack with President Trump new budget plan. So it’s important to keep pushing for better laws and policies to protect
Rhetor’s since the days of Aristotle and Isocrates have been using their rhetorical situations to deliver messages with a sense of urgency and persuade others to see their point of view. In 1933, Luther Standing Bear published his book “Land of the Spotted Eagle”. In this book, he talks about the terrible conditions under which his people live and how it needs to change. He speaks specifically to this in the excerpt “What the Indian Means to America”. Here he is referencing the Great Depression and the Dust Bowl. Standing Bear talks about how the European Americans caused these disasters and how the Native American could be the solution to these problems. He uses his rhetorical situation to try and convince the American government to listen

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.
In conclusion, owls have shown they are excellent at adapting to any environment by the ability to fly silently to stalk prey. They use camouflaged and insulated feathers to hide and keep warm while hunting. Owl’s excellent binocular vision, and hearing helps to track prey from long distances. The only real risk of extinction of the burrowing owl is if people continue to kill off animals that dig holes for them. They have shown the ability to survive for a long time with the help of other animals digging holes for them. Owl’s will continue to evolve long after humans have
In 1782, the bald eagle was elected as the national symbol of the United States of America, yet by the early 1960’s, it was nearly extinct in the Continental United States. A combination of many dangers, with the main danger being the pesticide DDT, the bald eagle was on the verge of extinction. Yet, through conservation measure applied by the United States government the bald eagle cam back from the brink and was taken off of the endangered species list in 2007.

“Evans and Emlen (1947) estimated that a Barn Owl in California ate 150 g per day. This may be too high as it was based on two pellets per day and available evidence indicates that American Barn Owls average less than that per day (Wallace, 1948 and this paper).”
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.

America’s Old Growth Forests are an endangered resource that is quickly disappearing. The ancient forests are being unnecessarily wasted, and are growing smaller and smaller with each passing moment.
In Birds, when one sex is a different size than the other, it is typically the male that is larger. However, in Hawks and Eagles, Falcons and Owls, the female is often larger than the male. Why?
This ground nesting bird’s population decreased from 16 million during the 1900’s to nearly 350,000 in 2010. That is nearly a 98% loss of all sage grouse. In 2004, the sage grouse was refused protection under the ESA. However, on Sep. 22, 2015, the sage grouse was found to warrant protection needs and inducted to the federal endangered species list. Amphibians and reptiles in the Southwest United States have posed major survival issues, in particular the Arizona Toad species found in Utah. These toads, as well as many other reptiles and amphibians, are experiencing excessive habitat loss along with other threats to their survival. The Arizona toad is currently under review to determine the severity of it’s threatened state and if it should be protected under the
