Hay Swamp
Hay Swamp (Hay Swamp Management Area) is a provincially significant wetland complex, 1839 hectares (4544 acres) in size, located in parts of the central land areas of the municipalities of Bluewater and South Huron, in southwestern Ontario, Canada. Approximately in length and in width, at its widest point; it consists of 15 extensively forested individual wetlands, situated on either side, of sections of both the upper drainage of the Ausable River and its tributary, Black Creek. Hay Swamp is situated at the northern limit of the Carolinian Biotic Province and is categorized as consisting of 98% swamp and 2% marshland. Apart from the Ausable and the Black, its primary source of water is considered to be the local Wyoming Moraine aquifer. Hay Swamp is an important regional habitat for wildlife populations including white-tailed deer, great blue heron, ducks, geese, as well as a significant beaver presence. The swamp is also home to several plant species at risk, including gree ...

Wetland
A wetland is a distinct ecosystem that is flooded or saturated by water, either permanently (for years or decades) or seasonally (for weeks or months). Flooding results in oxygen-free (anoxic) processes prevailing, especially in the soils. The primary factor that distinguishes wetlands from terrestrial land forms or Body of water, water bodies is the characteristic vegetation of aquatic plants, adapted to the unique anoxic hydric soils. Wetlands are considered among the most biologically diverse of all ecosystems, serving as home to a wide range of plant and animal species. Methods for assessing wetland functions, wetland ecological health, and general wetland condition have been developed for many regions of the world. These methods have contributed to wetland conservation partly by raising public awareness of the functions some wetlands provide. Wetlands occur naturally on every continent. The water in wetlands is either freshwater, brackish or seawater, saltwater. The main w ...

Species At Risk Act
The ''Species at Risk Act'' (SARA) (the ''Act'') is a piece of Canadian federal legislation which became law in Canada on December 12, 2002. It is designed to meet one of Canada's key commitments under the International Convention on Biological Diversity. The goal of the ''Act'' is to prevent wildlife species in Canada from disappearing by protecting endangered or threatened organisms and their habitats. It also manages species which are not yet threatened, but whose existence or habitat is in jeopardy. SARA defines a method to determine the steps that need to be taken in order to help protect existing relatively healthy environments, as well as recover threatened habitats, although timing and implementation of recovery plans have limitations. It identifies ways in which governments, organizations, and individuals can work together to preserve species at risk and establishes penalties for failure to obey the law. The ''Act'' designates COSEWIC, an independent committee of wildli ...

Protected Areas Of Huron County, Ontario
Protection is any measure taken to guard a thing against damage caused by outside forces. Protection can be provided to physical objects, including organisms, to systems, and to intangible things like civil and political rights. Although the mechanisms for providing protection vary widely, the basic meaning of the term remains the same. This is illustrated by an explanation found in a manual on electrical wiring: Some kind of protection is a characteristic of all life, as living things have evolved at least some protective mechanisms to counter damaging environmental phenomena, such as ultraviolet light. Biological membranes such as bark on trees and skin on animals offer protection from various threats, with skin playing a key role in protecting organisms against pathogens and excessive water loss. Additional structures like scales and hair offer further protection from the elements and from predators, with some animals having features such as spines or camouflage s ...

Conservation Authority (Canada)
A conservation authority is a local, community-based natural resource management agency based in Ontario, Canada. Conservation authorities represent groupings of municipalities on a watershed basis and work in partnership with other agencies to carry out natural resource management activities within their respective watersheds, on behalf of their member municipalities and the Province of Ontario. The 1946 ''Conservation Authorities Act'' provides the means by which municipalities within a common watershed can petition the Province of Ontario to form a conservation authority for that watershed to undertake programs of natural resource management. Conservation authorities are established as corporate bodies under the Act.https://www.e-laws.gov.on.ca/html/statutes/english/elaws_statutes_90c27_e.htm Conservation Authorities Act, e-Laws. There are currently 36 conservation authorities in Ontario. Conservation authorities are mandated to develop programs to further the conservatio ...

Sodom, Ontario
Sodom, Ontario, was a small Canadian logging industry-based community that existed in the last quarter of the 19th and first half of the 20th century. It was located on the boundary between the present day municipalities of South Huron and Bluewater, Ontario, Canada, on Dashwood Road approximately 500 meters west of the present-day intersection of Dashwood Road and Ausable Line, at the point at which Dashwood Road bridges the Ausable River. The original site of the community is now occupied by South Huron and Bluewater. History Sodom began in 1873 when two local businessmen constructed a sawmill. Thomas Greenway, a future Premier of Manitoba Province, formed a partnership with Robert Bissett for the enterprise, which was at first inadvertently built on land reserved for road construction, and had to be relocated to the west side of the Ausable River, south of Dashwood Road. The mill was situated in a densely forested old growth stand of hardwood trees in an area known as Hay Swam ...

Water Quality
Water quality refers to the chemical, physical, and biological characteristics of water based on the standards of its usage. It is most frequently used by reference to a set of standards against which compliance, generally achieved through treatment of the water, can be assessed. The most common standards used to monitor and assess water quality convey the health of ecosystems, safety of human contact, extend of water pollution and condition of drinking water. Water quality has a significant impact on water supply and oftentimes determines supply options. Categories The parameters for water quality are determined by the intended use. Work in the area of water quality tends to be focused on water that is treated for potability, industrial/domestic use, or restoration (of an environment/ecosystem, generally for health of human/aquatic life). Human consumption Contaminants that may be in untreated water include microorganisms such as viruses, protozoa and bacteria; inorganic ...

Baseflow
Baseflow (also called drought flow, groundwater recession flow, low flow, low-water flow, low-water discharge and sustained or fair-weather runoff) is the portion of the streamflow that is sustained between precipitation events, fed to streams by delayed pathways. It should not be confused with groundwater flow. Fair weather flow is also called base flow. Importance Baseflow is important for sustaining human centers of population and ecosystems. This is especially true for watersheds that do not rely on snowmelt. Different ecological processes will occur at different parts of the hydrograph. During the baseflow ascending limb, there is frequently more stream area and habitat available for water-dependent species, spawning salmon for example. During the recession limb which in California is from May to October, there is increasingly less stream area, indigenous species are more adept at surviving in low flow conditions than introduced species. Geology Baseflow is derived from ...

Flood
A flood is an overflow of water ( or rarely other fluids) that submerges land that is usually dry. In the sense of "flowing water", the word may also be applied to the inflow of the tide. Floods are an area of study of the discipline hydrology and are of significant concern in agriculture, civil engineering and public health. Human changes to the environment often increase the intensity and frequency of flooding, for example land use changes such as deforestation and removal of wetlands, changes in waterway course or flood controls such as with levees, and larger environmental issues such as climate change and sea level rise. In particular climate change's increased rainfall and extreme weather events increases the severity of other causes for flooding, resulting in more intense floods and increased flood risk. Flooding may occur as an overflow of water from water bodies, such as a river, lake, or ocean, in which the water overtops or breaks levees, resulting ...

Habitat (ecology)
In ecology, the term habitat summarises the array of resources, physical and biotic factors that are present in an area, such as to support the survival and reproduction of a particular species. A species habitat can be seen as the physical manifestation of its ecological niche. Thus "habitat" is a species-specific term, fundamentally different from concepts such as environment or vegetation assemblages, for which the term "habitat-type" is more appropriate. The physical factors may include (for example): soil, moisture, range of temperature, and light intensity. Biotic factors will include the availability of food and the presence or absence of predators. Every species has particular habitat requirements, with habitat generalist species able to thrive in a wide array of environmental conditions while habitat specialist species requiring a very limited set of factors to survive. The habitat of a species is not necessarily found in a geographical area, it can be the interior ...

Soil
Soil, also commonly referred to as earth or dirt, is a mixture of organic matter, minerals, gases, liquids, and organisms that together support life. Some scientific definitions distinguish ''dirt'' from ''soil'' by restricting the former term specifically to displaced soil. Soil consists of a solid phase of minerals and organic matter (the soil matrix), as well as a porous phase that holds gases (the soil atmosphere) and water (the soil solution). Accordingly, soil is a three-state system of solids, liquids, and gases. Soil is a product of several factors: the influence of climate, relief (elevation, orientation, and slope of terrain), organisms, and the soil's parent materials (original minerals) interacting over time. It continually undergoes development by way of numerous physical, chemical and biological processes, which include weathering with associated erosion. Given its complexity and strong internal connectedness, soil ecologists regard soil as an ecosystem. Most ...

Northern Riffleshell
The northern riffleshell (''Epioblasma torulosa rangiana''), is a subspecies of freshwater mussel, an aquatic bivalve mollusk in the family Unionidae, the river mussels. This subspecies is endangered. This species was formerly found widely in the Ohio River basin, but now the population is fragmented into only three viable groups. This river mussel needs gravel river beds and swift-flowing, well-oxygenated water. The reduction in range seems to be principally due to damming and the consequential silting up of rivers below the dam and competition from zebra mussels. Distribution and conservation status This species lives in Ontario in Canada. It was classified as endangered by COSEWIC. The Canadian Species at Risk Act listed it in the List of Wildlife Species at Risk The List of Wildlife Species at Risk currently has more than 800 entries for Canadian wild life species considered vulnerable; including 363 classified as endangered species, —190 threatened species, — ...

Ammocrypta
''Ammocrypta'' is a genus of freshwater ray-finned fish, commonly known as the sand darters, which is classified in the subfamily Etheostomatinae, part of the Family (biology), family Percidae which also includes the perches, Gymnocephalus, ruffes and Sander (fish), pikeperches. The species in the genus occur in eastern North America in Canada and the continental United States. Characteristics ''Ammocrypta'' species are characterised by having rather elongate and slender bodies. Their bodies are translucent and there is only a single spine in the anal fin. They also have Spreitzer vertebrae, that is that the first three vertebrae of the backbone, counting from the head, have an open haemal arch which allows for the fish's kidney to expand. They have the habit of burying into the sand or gravel bed of streams, only their eyes being visible. The translucence of their bodies and their habit of burying themselves gives them some protection against predation. The shared morphological ...
