Canada's Ecozones Canada’s Ecozones Unit Three Chapter 13 • Regions with similar ecological characteristics. • Include people and animals that live together. • Areas grouped according to geographic, geologic, landform, soil, vegetation, climate, water, wildlife and human interactions. • A recent concept – First map 1986. R.Schroeder Geo Unit 3 - Chapter 13 3 Ecozones • Divisions/groupings based on “systems” – Geologic – Landform – Soil – Vegetation – Climate – Water – Wildlife – Human Factors R.Schroeder Geo Unit 3 - Chapter 13 4 Overview • Changes to one part of the system causes changes and adjustments throughout the system. • e.g. Temperature changes within an ecosystem would affect the growth of plants, which then would have an affect on the animals ability to obtain food. R.Schroeder Geo Unit 3 - Chapter 13 5 • 15 Ecozones • All are different/unique due to climate, weather, soil, landforms, vegetation, animals and humans. R.Schroeder Geo Unit 3 - Chapter 13 6 Physiographic Regions R.Schroeder Geo Unit 3 - Chapter 13 7 Canadian Ecozones Fifteen Land and Five Marine • Mixed Plains • Hudson Plains • Boreal Shield • Southern Arctic • Atlantic Maritime • Northern Arctic • Prairie • Arctic Cordillera • Boreal Plains _____________________ • Montane Cordillera • Pacific Marine • Pacific Maritime • Arctic Basin Marine • Boreal Cordillera • Arctic Archipelago Marine • Taiga Cordillera • Northwest Atlantic Marine • Taiga Plains • Atlantic Marine • Taiga Shield R.Schroeder Geo Unit 3 - Chapter 13 8 Terrestrial & Maritime Ecozones R.Schroeder Geo Unit 3 - Chapter 13 9 Ecozones R.Schroeder Geo Unit 3 - Chapter 13 10 Ecozone Lingo • Mixed – To combine or blend. • Plains – Extensive, level, usually treeless. • Prairie – Treeless grassy plain. • Boreal – Forest areas dominated by conifers: spruce, fir, and pine. R.Schroeder Geo Unit 3 - Chapter 13 11 Ecozones R.Schroeder Geo Unit 3 - Chapter 13 12 Ecozone Lingo • Shield – ancient, stable, interior layer of primarily Precambrian igneous or metamorphic rocks. AKA Continental Shield. • Maritime – close/next to the sea. • Montane – of, growing in, or inhabiting mountain areas. • Cordillera – Extensive/principal mountain ranges of a continent. R.Schroeder Geo Unit 3 - Chapter 13 13 Ecozones R.Schroeder Geo Unit 3 - Chapter 13 14 Ecozone Lingo • Taiga – Subarctic, coniferous forest south of the tundra and dominated by firs and spruces. • Tundra – Treeless area between icecap and tree line of arctic regions with permanently frozen subsoil (permafrost) and supporting low-growing vegetation: lichens, mosses, and stunted shrubs. • Arctic – Region between North Pole and northern timberlines.

R.Schroeder Geo Unit 3 - Chapter 13 21 Ecozone Systems • Landforms – Topography and type. • Climate – Temperature extremes, precipitation, and growing season. • Vegetation – What grows, what dominates? • Soils – Type? Leached, swamp, rock? • Human Activities – Population, GDP, urbanization, manufacturing, agriculture, recreation • Major Cities R.Schroeder Geo Unit 3 - Chapter 13 22 • Ecozones are always changing and growing!

In exposures, relict glacier ice and intrasedimental ice often coexist and look alike but their genesis is strikingly different. This paper aims to present a detailed description and infer the origin of a massive ice body preserved in the permafrost 15 of Bylot Island (Nunavut). The massive ice exposure and core samples were described according to the cryostratigraphic approach, combining the analysis of permafrost cryofacies and cryostructures, ice crystallography, stable O-H isotopes and cation contents. The ice was clear to whitish in appearance with large crystals (cm) and small gas inclusions (mm) at crystal intersections, similar to observations of englacial ice facies commonly found on contemporary glaciers and ice sheets.

  • Ecoregions with Grasslands in British Columbia, the Yukon, and Southern Ontario
    83 Chapter 4 Ecoregions with Grasslands in British Columbia, the Yukon, and Southern Ontario Joseph D. Shorthouse Department of Biology, Laurentian University Sudbury, Ontario, Canada P3E 2C6 Abstract. The second largest grasslands of Canada are found in south-central British Columbia in valleys between mountain ranges and on arid mountain-side steppes or benchlands. The province contains five ecozones, with most of the grassland habitat in the Montane Cordillera Ecozone. This ecozone consists of a series of plateaux and low mountain ranges and comprises 17 ecoregions, 7 of which contain grasslands. Dominant grasses here are bunchgrasses. A few scattered grasslands are found in the Yukon in the Boreal Cordillera Ecozone within three ecoregions. Grasslands in southwestern Ontario consist of about 100 small remnants of what was once much more abundant tallgrass prairie. These grasslands grow in association with widely spaced deciduous trees and are remnants of a past prairie peninsula. Grasslands called alvars are also found on flat limestone bedrock in southern Ontario. This chapter briefly describes the physiography, climate, soils, and prominent flora of each ecoregion for the benefit of future biologists wishing to study the biota of these unique grasslands. Résumé. Les prairies du centre-sud de la Colombie-Britannique sont les deuxièmes plus vastes au Canada. Elles se trouvent dans les vallées séparant les chaînes de montagnes, et sur les steppes ou replats arides à flanc de montagne. La province renferme cinq écozones, et l’habitat de prairies se trouve principalement dans l’écozone de la cordillère alpestre. Cette écozone est constituée d’une série de plateaux et de chaînes de montagnes basses et se divise en 17 écorégions, dont 7 renferment des prairies.

  • The Ecozones of BC, with Special Reference to Lepidoptera (PDF)
    The Ecozones of British Columbia, with special reference to Lepidoptera Robert A. Cannings Royal British Columbia Museum November 2016 Introduction This treatment of the ecozones of British Columbia is slightly modified from the one I wrote in The Checklist of the Lepidoptera of British Columbia, Canada (Pohl et al. 2015). Ecozone and Biogeoclimatic Zone information is integrated. Authors of annotated checklists of various taxa in the province might find it a useful framework in which to discuss the biodiversity and distribution of species in the groups in question. The most useful summaries of British Columbia’s environment are found in Meidinger and Pojar (1991), BC Ministry of Forests and Range (2013), Demarchi (1996), and Cannings and Cannings (1996). The following details are mostly taken from these publications. Large and diverse, British Columbia (BC) is exceptionally variable physically and biologically. Covering almost 950,000 sq km, the province spans 11 degrees of latitude and 25 degrees of longitude. It is about 1300 km from the southern coast of Vancouver Island to the northern boundary at 60˚ N and, along this latitude, the boundary with the Yukon and the Northwest Territories stretches almost 1100 km. Mountains and the sea-bound coast, studded with islands, epitomize BC, and the region is mostly cool, moist, forested and mountainous. But such generalities do not do justice to the striking diversity of wet and dry forests, grasslands, wetlands, scrub and alpine tundra forming complex mosaics of habitat across vast plateaus, valleys and plains lying among several northwest-southeast trending mountain ranges. Climates range from semi-arid and Mediterranean to subarctic and alpine.
