INTRODUCTION: The Coypu (Myocastor coypus) is a large, robust, semi-aquatic rat like rodent and a casual observer may misidentify a Coypu as a beaver or a muskrat, especially when it is swimming. However, this superficial resemblance ends when a more detailed study of the animal is made (LeBlanc. 2005). The average size of the head and body is 52cm with the length of the tail being an additional 37cm. The body is highly arched with a large almost triangular head. The Incisors are large with an

Silver Creek Wetland Complex is a rare coastal wetland found along the eastern side of the Nottawasaga Bay Shoreline. It falls within the town boundary of the Town of Collingwood, which was formally a part of the Town of Blue Mountains. Because the area is a part of the greater Silver Creek Watershed, the marshy land is classified as a Schedule B Category 1 land under Environmental Protection as per the Official Plan of the Town of Collingwood. Blue Mountain Trust Watershed Practice monitors the

reducing base flow. 2.7 Landscape and Biotic Features The Georgian Trail provides a connection between the south ends of Silver Creek to the North, where the wetlands lie. This trail is significant as it provides access to the marsh which is a critical habitat for sensitive marsh bird species. It allows access to study the forested area, and study of endangered species, such as the western chorus frog (Pseudacris triseriata) that utilizes the wetlands as a breeding habitat. The deciduous and coniferous

study, researchers focused on determining the thresholds of marsh resilience near the Deepwater Horizon oil spill. It is important to identify ecosystem stress thresholds to prevent these ecosystems from experiencing stress thresholds that exceed their resilience. If stress exceeds these thresholds, any small change in an environmental stressor can cause an inevitable decline in overall ecosystem health. Researchers tested 103 salt marsh sites ranging up to about 430 kilometers from coastal Louisiana

The Shortland Wetlands have became one of the most popular and well-known attractions in Newcastle for its extensive wildlife, many activities and intensive research on conservation of many topics. (Wetlands.org.au) There are many biotic features of the wetlands and these include the Pampas grass, the elm (both of these are seriously terrestrial weed species). There are also other varying biotic factors such as the diversity and quantity of the plants and animals found there. (Tpwd.texas.gov)

be seen from shifts on the dense grass in the marsh to the unvegetated mud flats in the marsh. In the experiment, the top-down and bottom-up effects were monitored to investigate the cause of shift or die-off. This experiment is significant because it would be considered the first experiment to explain the die off factors that are caused by top-down and bottom-up control instead of physical factors. There were cage treatments implemented across the marsh to see if the hypothesis that questioned whether

Across all projects, the first step in tidal wetland restoration is almost always to create a “restoration site template” that will form the basis of the entire project. Experts believe that “restoring the physical integrity of the tidal wetland offers the best opportunity of restoring ecologic integrity” (Faber “Design” 17). How the template is formed will ultimately dictate what the final wetland will look like. Construction of the wetland base may require either excavation or fill depending

Louisiana is a place of beautiful wildlife and landscape. With about forty percent of the state being marshes and wetlands. It is very important for us to preserve these wetlands and keep them from disappearing like they have been for the past fifty years. Almost eighty percent of wetland loss in the nation has happened in Louisiana. Just in the past ten years the state has seen a thirty percent deduction in the wetlands. The bad thing about these wetlands disappearing is that they are just being

Wetland Restoration Most people think they know a wetland when they see one, but the delineation of wetlands for the purpose of granting permits has proven enormously controversial. According to the Environmental Protection Agency (EPA), an area is defined as a wetland when a combination of three technical criteria are met: Wetland hydrology (land that is saturated within 18 inches of the surface for more than seven days per year), Hydrophytic vegetation (a list of plants that will thrive in wet

Geography 3480 James Keogh Salt Marsh Harvest Mouse Image by B. Moose Peterson via Smithsonian Institute Abstract: There is very little known about the Salt Marsh Harvest Mouse (SMHM). In 1970, SMHM was added to the endangered list, largely due to the fact their salt water habitats 84% gone. With the mouse being just under 3 inches in length, nocturnal, loving its dense cover protection, and the close resemblance to the Western Harvest Mouse, it makes field identification very difficult.
