The Sifton Bog Environmentally Significant Area is a wetland jointly administered by the city of London, Ontario and the Upper Thames River Conservation Authority. It is located west of Hyde Park Road and south of Oxford Street inside the city limits of London, Southern Ontario, Canada. It is a Class 2 provincially significant wetland. [1]

Prior to 1967 the wetland was called "Byron Bog", having been at that time within the boundaries of the village of Byron, but it was renamed following the donation of the land by the "Sifton Properties Limited". However, it had undergone a series of name changes before this time also, being variously named Foster's Bog and Redmond's Bog in the 1880s, after the occupants of the land at that time, and Spruce Bog in the 1890s. The name Byron Bog was used by the 1920s, but no record exists of its Native American name. [2]

The Sifton Bog is one of the most southerly acidic bogs in Canada. It contains a number of rare species including four types of carnivorous plants. [3] Among the latter are the sundews Drosera intermedia and Drosera rotundifolia [4] and the purple pitcher plant Sarracenia purpurea . [5] The central bog vegetation is dominated by Sphagnum and Chamaedaphne calyculata (leatherleaf), with a few short larches ( Larix laricina ) and black spruce ( Picea mariana ). [6]

The depression that houses the bog was created like many local geologic features, by the effects of glaciation. [7] A depression in the Ingersoll Glacial Moraine was left by retreating glaciers. The result was a pocket with no drainage which developed into the Sifton Bog. [7] The 0.2 hectare pond at the centre of the bog, Redmond's Pond, is the remnant of what would have originally been a larger 23 hectare water body, which has gradually filled with peat over the last 10000 years. [2] The peat layer at the centre of the bog has been measured at 18 m (60 ft). [6]

Redmond's Pond is named after the Redmond family, who owned part of the land on which the bog is situated, between 1854 and 1900. [2] The pond is less than 1.5 m (5 ft) deep, and has a pH of around 5. On the margins are surface growths of the carnivorous bladderwort Utricularia vulgaris and water lily Nuphar advena , with sparse growths of duckweed ( Lemna minor ) and water flax-seed ( Spirodela polyrhiza ). [6]

The bog was previously used as a commercial source of sphagnum moss, an alternative to cotton gauze. It was mined during the First World War to support the war effort and the needs of local hospitals. The Alder Buckthorn, a plant native to the bog, was harvested and used during the Second World War to produce gunpowder. [3]

<span class="mw-page-title-main">Bog</span> Type of wetland that accumulates peat due to incomplete decomposition of plant matter

A bog or bogland is a wetland that accumulates peat as a deposit of dead plant materials – often mosses, typically sphagnum moss. It is one of the four main types of wetlands. Other names for bogs include mire, mosses, quagmire, and muskeg; alkaline mires are called fens. A baygall is another type of bog found in the forest of the Gulf Coast states in the United States. They are often covered in heath or heather shrubs rooted in the sphagnum moss and peat. The gradual accumulation of decayed plant material in a bog functions as a carbon sink.

<i>Drosera</i> Genus of carnivorous flowering plants in the family Droseraceae

Drosera, which is commonly known as the sundews, is one of the largest genera of carnivorous plants, with at least 194 species. These members of the family Droseraceae lure, capture, and digest insects using stalked mucilaginous glands covering their leaf surfaces. The insects are used to supplement the poor mineral nutrition of the soil in which the plants grow. Various species, which vary greatly in size and form, are native to every continent except Antarctica.

<i>Drosera capillaris</i> Species of carnivorous plant native to subtropical to tropical North and South America

Drosera capillaris, also known as the Pink Sundew is a species of carnivorous plant belonging to the family Droseraceae. It is native to the Southern United States, the Greater Antilles, Eastern and Southern Mexico, Central America, and Northern South America. It is listed as vulnerable in the US state of Virginia, and critically imperiled in Arkansas, Maryland, and Tennessee.

<i>Drosera rotundifolia</i> Species of flowering plant in the sundew family Droseraceae

Drosera rotundifolia, the round-leaved sundew, roundleaf sundew, or common sundew, is a carnivorous species of flowering plant that grows in bogs, marshes and fens. One of the most widespread sundew species, it has a circumboreal distribution, being found in all of northern Europe, much of Siberia, large parts of northern North America, Korea and Japan but is also found as far south as California, Mississippi and Alabama in the United States of America and in New Guinea.

<i>Drosera anglica</i> Species of carnivorous flowering plant in the family Droseraceae

Drosera anglica, commonly known as the English sundew or great sundew, is a carnivorous flowering plant species belonging to the sundew family Droseraceae. It is a temperate species with a circumboreal range, although it does occur as far south as Japan, southern Europe, and the island of Kauai in Hawaii, where it grows as a tropical sundew. It is thought to originate from an amphidiploid hybrid of D. rotundifolia and D. linearis, meaning that a sterile hybrid between these two species doubled its chromosomes to produce fertile progeny which stabilized into the current D. anglica.

<span class="mw-page-title-main">Bog garden</span>

A bog garden is a type of garden that employs permanently moist soil to create a habitat for plants and creatures which thrive in such conditions. It may exploit existing poor drainage in the garden, or it may be artificially created using pond liners or other materials to trap water in the area. Any such structure must allow a small amount of seepage to prevent the water stagnating. For instance, a pond liner must be pierced a few times. Typically a bog garden consists of a shallow area adjoining a pond or other water feature, but care must be taken to prevent water draining from a higher to a lower level. The minimum sustainable depth is 40–45 cm (16–18 in). Good drainage is provided by gravel placed over the liner, and the bog can be kept watered by using a perforated hose below the surface.

The Portlethen Moss is an acidic bog nature reserve located to the west of the town of Portlethen, Aberdeenshire in Scotland. Like other mosses, this wetland area supports a variety of plant and animal species, even though it has been subject to certain development and agricultural degradation pressures. For example, the Great Crested Newt was found here prior to the expansion of the town of Portlethen. Many acid loving vegetative species occur in Portlethen Moss, and the habitat is monitored by the Scottish Wildlife Trust.

<i>Drosera intermedia</i> Species of carnivorous flowering plant in the family Droseraceae

Drosera intermedia, commonly known as the oblong-leaved sundew, spoonleaf sundew, or spatulate leaved sundew, is an insectivorous plant species belonging to the sundew genus. It is a temperate or tropical species native to Europe, southeastern Canada, the eastern half of the United States, Cuba, Hispaniola, and northern South America.

Pinhook Bog is a unique bog in Indiana that has been designated a National Natural Landmark. It is part of Indiana Dunes National Park, an area that many citizens, scientists, and politicians fought hard to preserve. Its sister bog, Volo Bog, is located nearby. The bog contains a large variety of plants, including insect eating plants, tamarack trees, stands of blueberry bushes, and floating mats of sphagnum moss. Pinhook Bog is about 580 acres (2.3 km2), a quarter of which is a floating mat of sphagnum peat moss. A "moat" separates the bog from the uplands.

<span class="mw-page-title-main">Carnivorous plant</span> Plants that consume animals

Carnivorous plants are plants that derive some or most of their nutrients from trapping and consuming animals or protozoans, typically insects and other arthropods, and occasionally small mammals and birds. They still generate all of their energy from photosynthesis. They have adapted to grow in places where the soil is thin or poor in nutrients, especially nitrogen, such as acidic bogs. They can be found on all continents except Antarctica, as well as many Pacific islands. In 1875, Charles Darwin published Insectivorous Plants, the first treatise to recognize the significance of carnivory in plants, describing years of painstaking research.

<i>Lysimachia asperulifolia</i> Species of plant

Lysimachia asperulifolia is a rare species of flowering plant in the Primulaceae known by the common name rough-leaved loosestrife and roughleaf yellow loosestrife. It is endemic to the Atlantic coastal plain in North Carolina and northern South Carolina in the United States, where there are 64 known populations. It is a federally listed endangered species of the United States.

A cataract bog is a rare ecological community formed where a permanent stream flows over a granite outcropping. The sheeting of water keeps the edges of the rock wet without eroding the soil; in this precarious location no tree or large shrub can maintain a roothold. The result is a narrow, permanently wet, sunny habitat.

<i>Vaccinium oxycoccos</i> Species of flowering plant

Vaccinium oxycoccos is a species of flowering plant in the heath family. It is known as small cranberry, marshberry, bog cranberry, swamp cranberry, or, particularly in Britain, just cranberry. It is widespread throughout the cool temperate northern hemisphere, including northern Europe, northern Asia and northern North America.
