Oshawa's Second Marsh: A Case Study

* Restoring lagoon-side bush * Removing weeds and non-native plants * Planting suitable trees, shrub, grass, etc. * The efforts of “Terrigal Lagoon Bushcare” have been largely successful in keeping the lagoons around Terrigal ecosystems. Their actions have helped the native plants compete with the introduced species.

Also known as salt cedar, the Tamarisk plant was imported in the 1850’s as an ornamental plant and also used as a method to control erosion. There are a few pros to this invasive species but they do pose a concern. Tamarisk not only crowds out natural riparian vegetation, but also consumes an alarming amount of water. To effectively save as much water in the river as possible, putting an end to this invasive species may be necessary. Since the Tamarisk roots run deep, it helps out a lot with erosion, however it consumes a significant amount of water. Tamarisk covers about 50,000 acres of the Colorado basin area and consumes more water annually than the rivers native vegetation. Not only do these plants deplete the water but the animals living in areas where the tamarisk grows, are usually fewer in number and type, and are less healthy then animals in areas where Tamarisk does not grow. Although the issue with the Tamarisk plant is very small compared to the other issues involving the river, it is still important that the plant be removed to improve and conserve the Colorado River (Nijhuis).

6. Fence constriction shall not result in any vegetation clearing, An up-to-date survey of the entire property which shows the existing improvements and the location of all wetlands and poorly and very poorly drained soils (including wetland flag numbers), wetland buffer, and 12’ primary structure setback from the buffer edge. The survey should be prepared by a licensed surveyor. For properties where the wetland delineation is older than 3 years, the professional who did the original delineation should reconfirm the accuracy of the boundaries in writing as part of the application. The Conservation Commission reserves the right to request documentation/notes for any wetlands delineation.

As decades continued to pass by the wetlands change. "People have begun to realize that wetlands are valuable and productive ecosystems that fulfill an essential function for both humans and wildlife. Due to their unique characteristics, wetlands can support a wide diversity of plants, mammals, reptiles, birds and fish. They also control floodwaters and protect us from storms and hurricanes. Wetlands also improve water quality by filtering, cleaning and storing water. Lastly, many people rely on wetlands for their livelihood, as they are important centers for hunting, fishing and recreation." Referring to this from "Wetlands and Habitat Loss", we now see how wetlands are valuable and helpful to the ecosystem. The wetlands are known for our water source. Many people depend on the Everglades for a water source. We also use the Everglades for activities. These activities include fishing, recreation, and

Baldwin swamp is an urban wetland, located in the heart of Bundaberg, providing a habitat to a range of organisms. The environment is rich in biodiversity; with more than 150 species of birds, variety of vegetation/plants as wells as creatures and mammals ranging from tiny aquatic wrigglers to bats, which have recently inhabited the area. Wetlands can be swamps, boys and or areas next to creeks. The Baldwin swamp can be best described as a network of ponds/swamps that channels into landscapes of grassland. This area has a significant ecological impact as the relationships among the organisms in relation to their food webs is vital to their survival. Abiotic factors such as humidity, soil, pollution, Ph levels, temperature, dissolved oxygen

1.2 Public Land Management – Conservation Qualifications In 1985, the Ministry of Natural Resources (MNR) evaluated the Silver Creek Wetland, and qualified it for environmental protection. A re-evaluation was done in 1995, and a decision was made to combine three areas into one complex. The provincially significant wetland is listed as “unimpaired” and protection was recommended in 2000 by Nottawasaga Valley Conservation Authority’s watershed health monitoring summary. As the area provides vital biological, social, and hydro geological functions, protection is crucial. Not only does the area act as flood control, water purification, and sediment containment, it is a prime fishing location for locals as it provides a cold-water habitat and spawning grounds for several varieties of game fish such as brook trout (Salvelinus fontinalis), Chinook salmon (Oncorhynchus tshawytscha), and rainbow trout (Oncorhynchus mykiss). Numerous species of birds, such as the Caspian terns (Hydroprogne caspia), the great egret (Ardea alba), the black-crowned night heron (Nycticorax nycticorax), and other waterfowl also favour the staging and feeding grounds that the

Ecosystem is an important part of the environment and to protect the Australian native ecosystem many management plans are made to preserve it. Where the disruption occurred in the environment by human activities is not only the factor of worry, but also the exotic plants which are trying to take over the native species are a matter of concern too. The steps taken by humans to get rid of their own waste from the environment as well as the weeds, come under management plans. On the excursion to Buckley’s Hole, Godwin Beach, Red Beach and Melaleuca Wetland, it was observed that these areas come under the Buckley’s Hole Management Plan. Where the abiotic and biotic factors interact with each other and help in sustainability of better environment.

3.2 About the Issue Shrimptons Creek Parklands, located in the City or Ryde in the northern Suburbs of Sydney, comprises of seven parks that lie adjacent to Shrimptons Creek. The creek is approximately 3.3 kilometres in length, flowing in a north-south direction through the suburbs of Denistone East, Ryde and Macquarie Park.

The wetlands does only help the wildlife and humans it helps from damaging property, Now you think I'm crazy but I'm not ok, now listen, wetland can help us by storm like hurricanes', floods, and many more. Take for example, in New Orleans, Louisiana, has suffered extremely consequence of the hurricane Katrina, one of the most powerful hurricane in the entire untied states history. Scientist believe that hurricane would did less damage if they had more wetlands, but in the 1800's they destroy the wetlands for more land and because the mosquitos that cause the yellow

Many wetlands are beginning to die out. Look at the everglades for example they’ve been here for 5000 years! Back then they were pretty and all new, but now it is starting to look like the famous scene from the Indiana Jones movie "Raiders of the Ark" says the article "Are the Everglades Forever? My first reason is that Its majestic waters will turn into swampy waters filled with snakes and who knows what. Also if wetlands die out there will be habitat loss until they cannot find home and eventually dies out plus people are releasing animals out into the wild which is not a good thing because then animals start to compete for food The final reason we should care about wetland is that they provide thing for us to such as the everglades provides

For this week’s forum, after searching for “wetlands restoration,” I found a local wetlands restoration project that was completed in November 2011 and encompassed an area of 150 acres. The San Dieguito Wetland Restoration Project included the coastal area of San Dieguito Lagoon and the San Dieguito River Park – estuarine and riverine wetland systems, respectively - which serve an important role in the local ecology. They provide a stop for birds along the Pacific Flyway, nesting and foraging areas for endangered species and serve as a fish hatchery.

Louisiana’s Gulf Coast is eroding into the sea, and by 2100 most of Southeast Louisiana could be completely underwater. Not only does this threaten human and animal habitats, but also the energy, shipping, fishing, and tourist industries that have made this region of the U.S. a valuable part of the national economy (Marshall, 2014). In the past 200 years, half of the nation’s wetland habitats have been lost due to natural and manmade processes. Louisiana’s wetlands make up 40 percent of the total wetlands in the continental United States. 80 percent of losses, nationally, are of Louisiana’s coast (Williams).

The Burns Bog Ecological Conservancy Area (BBECA) is a remnant ombrotrophic raised bog ecosystem expanding for approximately 22 km2 between the south arm of the Fraser River and Boundary Bay in Metro Vancouver, British Columbia (Fig. 1). The entire remaining bog is a unique ecosystem complex of global significance due to its size and form, location on a large estuarine delta with chemistry influenced by the nearby marine environment, and flora, supporting distinctive bog vegetation communities and recognized rare and endangered plant and wildlife species (Hebda et al., 2000). The BBECA contains about 14 km2 of disturbed wetland ecosystems with previous use of peat mining, agriculture or recreation, and about 6 km2 of relatively undisturbed

Figure 2. Grady Tract map including community types and trails. This project builds on the work of an earlier project titled “Regional and Local Pathways to a Globally Esteemed Ecologically-Restored Landscape”, funded by the Partners for Recreation and conservation (PARC), which cleared more than 22 acres of invasive shrub, used herbicide to control the re-sprouts to maintain clearings and made seeding and planting to increase native plant diversity. In addition, visitor access and safety issues were also part of this project, repairing and improving the existing fencing and creating a new access point near the Arbor Hills Neighborhood.

Literature review: http://www.environmental+science+.org/bird-environmental-indicators (Refer to appendix 1 for article) In this article it speaks about many different types of indicators that one could see in order to determine the ecological state of the wetland by my factors such as the biodiversity, pollution levels, the fauna and flora in the wetland. This relates to our wetland as we have a large biodiversity in our wetland with little pollution as well as plants such as reeds growing which indicate a healthy wetland. We also occasionally see a large variety of birds in our wetland therefore another indicator that our wetland is healthy.
