Spirit Bear

Spirit bears are rare white-coated black bears (Ursus americanus kermodei) that live in the coastal temperate rainforests of Northwest British Columbia. Their striking colour is caused by an uncommon recessive genetic trait. Spirit bears are not a unique species or subspecies, but a unique colouration of the coastal British Columbian black bear subspecies kermodei. Referred to as moksgm’ol, meaning “white bear,” by Tsimshian coastal First Nations, spirit bears play an important role in local culture and increasingly in Indigenous-led ecotourism.

Resource Towns in Canada

Resource towns are small, isolated communities built around resource-based industries and transportation. They include mining towns, mill towns, railway towns and fishing villages. Resource development has long been a key factor in shaping the settlement and growth of communities. Some scholars have argued that all Canadian urban growth depends on the production of natural resources. (See also Staple Thesis.) Resource towns have been important agents in this production process. Because they depend on single industries, the economies of resource towns are often unstable.

Halibut Treaty

The Halibut Treaty of 1923 (formally the Convention for the Preservation of Halibut Fishery of the Northern Pacific Ocean) was an agreement between Canada and the United States on fishing rights in the Pacific Ocean. It was the first environmental treaty aimed at conserving an ocean fish stock. It was also the first treaty independently negotiated and signed by the Canadian government; one of several landmark events that transitioned Canada into an autonomous sovereign state. It also indicated a shift in Canada’s economic focus from Britain to the US during the 1920s, when the US passed Britain as Canada’s largest trading partner. The treaty created the International Pacific Halibut Commission, which continues in its role today.

Bison

Bison are large, even-toed hoofed mammals of the family Bovidae. Two subspecies of bison exist in North America: the plains bison (Bison bison bison) and the wood bison (Bison bison athabascae). Historically, the plains bison lived primarily in the Great Plains of central North America, while the wood bison lived further north, from Alaska into the Yukon and the Northwest Territories, and in the northern portions of British Columbia, Alberta and Saskatchewan. Prior to the arrival of Europeans, it’s estimated that plains bison numbered 30 million and wood bison 170,000. Various aspects of European colonization led to the rapid depopulation of North America’s bison. By the late 1800s, plains bison no longer existed in Canada, and wood bison numbered about 200. Conservation efforts in both Canada and the United States mean that today, North America’s plains bison population fluctuates between 350,000 and 400,000, and wood bison between 5,000 and 7,000.

Land Cession

A land cession is a transfer of land from one party to another through a deed of sale or surrender. Land cessions may also be referred to as land surrenders and land purchases. In Canada and the United States, Indigenous land cessions generally took place through negotiated treaties. There are cases, however, where Indigenous peoples claim that lands were taken unjustly. The Royal Proclamation of 1763 established the protocols for land cession in both Canada and the United States.

Floods in Canada

Floods are primarily caused by naturally occurring changes in the height of rivers, lakes and oceans. According to Public Safety Canada, floods are the most common natural hazard in the country and among the costliest. Historic floods have occurred across Canada, with many of the worst happening on major river systems that pass through populated areas. Scientists predict that flooding linked to the impacts of climate change will increase as the 21st century progresses, particularly in coastal areas of the country.

Traditional Plants and Indigenous Peoples in Canada

Indigenous peoples in what is now Canada collectively used over a 1,000 different plants for food, medicine, materials, and in cultural rituals and mythology. Many of these species, ranging from algae to conifers and flowering plants, remain important to Indigenous communities today. This knowledge of plants and their uses has allowed Indigenous peoples to thrive in Canada’s diverse environments. Many traditional uses of plants have evolved to be used in modern life by Indigenous and non-Indigenous peoples alike. (See also Indigenous Peoples’ Medicine in Canada.)

Moss

Moss is a small terrestrial plant, usually less than 10 cm tall, that lacks true conducting tissues (xylem, phloem) and has a dominant gametophyte (sexual) generation. Mosses are the largest and most highly developed group of division Bryophyta (which also includes liverworts and hornworts). Bryophytes are sometimes known as the “amphibians of the plant world” because of their dependence on water for sexual reproduction. There are over 10,000 species of moss worldwide, of which about 1,250 are found in North America. Individual parts of Canada have fewer species (e.g., 466 species in Alberta, 445 in Newfoundland, 430 in Ontario). Mosses thrive in humid climates, and coastal parts of Canada have a greater diversity than the interior parts.

Fur Trade in Canada (Plain-Language Summary)

The fur trade began in the 1600s in what is now Canada. It continued for more than 250 years. Europeans traded with Indigenous people for beaver pelts. The demand for felt hats in Europe drove this business. The fur trade was one of the main reasons that Europeans explored and colonized Canada. It built relationships between Europeans and Indigenous peoples.

Endangered Animals in Canada

Many animals in Canada face the risk of extinction. Animals are put at risk for several reasons, including: climate change, the loss of forest and grassland to cities and agriculture, hunting, fishing, and the pollution of lakes and rivers. As of 2021, 554 animal species are at risk in Canada, according to the Committee on the Status of Endangered Wildlife in Canada. In addition, 18 are extirpated and 18 extinct. The committee’s definition of a wildlife species includes taxonomic categories as well as geographically distinct populations. For example, the beluga whale (Delphinapterus leucas) is included in the list of at risk animal species six times, as there are six different populations facing different threats to their survival. (See also Endangered Plants in Canada.)

Potato Wart Disease

Potato wart disease, also called potato canker, is a fungal disease of potato sprouts, eyes and stolons. The disease is caused by the soil-borne fungus, Synchytrium endobioticum. Potato wart disease poses no danger to human health or food safety, but it can impact local economies as the disease can reduce yield and effect economic regulations, such as potato exports. (See also Agricultural Economics.)

Sustainable Development

Sustainable development has been defined by the United Nations (UN) as development that “meets the needs of the present” while ensuring the future sustainability of the planet, its people and its resources. Meeting these needs often requires balancing three key features of sustainable development: environmental protection, economic growth and social inclusion. The goals of sustainable development are interconnected. The most successful sustainable development projects will include environmental, economic and social considerations in their final plan. These considerations must include the free, prior and informed consent of any Indigenous groups impacted by a sustainable development project.

Natural Resources in Canada

Natural resources are aspects of the natural environment from which goods and services can be obtained and produced. They include air, sunlight, water, land, vegetation, animal life and geological resources. People can also value natural resources for their own sake or for their aesthetic qualities. Humans must manage natural resources to sustain the benefits they offer.

Canada is among the most resource-rich countries in the world. Its large and varied natural resources are essential to its economies and cultures. But there are ongoing debates about how to use, share and manage natural resources.

Mantid

Mantids are carnivorous insects of the order Mantodea, known for their prayer-like posture. Mantids are most closely related to cockroaches and termites. There are about 2,400 species worldwide, most of which are found in the tropics. Only three species are found in Canada: the European mantis (Mantis religiosa), the Chinese mantid (Tenodera aridifolia) and the ground mantid (Litaneutriaminor). Of these three species only the ground mantid, found in southern British Columbia, is native.

Although mantis is sometimes used to refer to the entire group, most entomologists prefer to use that word for members of the genus Mantis.

Turtle Island

For some Indigenous peoples, Turtle Island refers to the continent of North America. The name comes from various Indigenous oral histories that tell stories of a turtle that holds the world on its back. For some Indigenous peoples, the turtle is therefore considered an icon of life, and the story of Turtle Island consequently speaks to various spiritual and cultural beliefs.
