Description

Derived Ecosite Phase (DEP) v2.0 is a digital and spatial representation of ecological sites and phases in those areas of Alberta where both Alberta Vegetation Inventory (AVI) and lidar are available. The AVI is an imagery-based digital inventory developed to identify the type, extent and conditions of vegetation, where it exists and what changes are occurring. The most up-to-date ecological site phases can be found in the Ecological Site Guides. Guides are broken into individual Natural Subregions. See the Cross Reference Section for additional information. This dataset is produced for the Government of Alberta and is available to the general public. Please consult the Distribution Information of this metadata for the appropriate contact to acquire this dataset.This dataset covers the areas of Alberta where there is both AVI and lidar coverage (mainly in the Green Area). AVIE and lidar-derived slope position were created by the Forest Stewardship and Trade Branch, Forestry...

Description

These long-term population projections by single year of age and sex have been developed by applying the component cohort survival model to assumptions about future trends in fertility, mortality and migration, under three different sets of assumptions (i.e. low, medium and high scenarios). Includes estimated (1996-2019) and projected (2020-2046) population of Alberta and its 19 Census Divisions, by single year of age and sex, as well as selected summary tables.

Description

The data, created in ArcGIS, represents an assessment of air quality risk for the agricultural area of Alberta in 2005. Agricultural activities that may have some influence on air quality manure production (odour) and cultivation intensity (particulate matter). The airsheds of the agricultural region of Alberta are considered to be uniform in their physical susceptibility to risk from agricultural activities. Air quality risk is a useful measure for those concerned about health, safety and nuisance issues related the quality of air in agricultural areas. Awareness of where agricultural activities related to livestock production and intensive cultivation are located, may be useful for people with health or nuisance related concerns. Blowing soil can cause respiratory problems and can reduce visibility on roads and highways. Dust from farm traffic can be a concern during peak agricultural activity, such as harvesting or manure hauling. Frequent strong odours can be unpleasant nuisance...

Description

This map displays the distribution of the main soil types found within the province of Alberta. The distribution pattern of soils in Alberta is strongly linked to climate and parent materials. Climate affects the location of different soil groups. The driest area in southeastern Alberta is represented by the presence of Brown Chernozems. As one proceeds north and west, the soils and associated vegetation reflect the increase in available moisture.In Alberta, Organic soils generally occur in association with Luvisolic soils. These soils form under wet conditions where the organic layer (greater than 30% organic matter) accumulates faster than it decomposes. The organic layer varies in thickness from 40 to 160+ cm, and under natural conditions, the water table is at or near the surface. In some areas of the province, Organic soils may be artificially drained and used for agricultural production. This resource was created in 2002 using ArcGIS.

Description

This map displays the risk of soil degradation by wind in the agricultural region of Alberta. Wind erosion is a concern because it reduces soil quality by removing soil nutrients, smaller soil particles and organic matter. Wind erosion can reduce air quality during extreme erosion events and also reduce water quality if eroded particles drift into streams and lakes. The map uses five classes to describe the wind erosion risk on bare, unprotected mineral soil: negligible, low, moderate, high and severe. This resource was created using ArcGIS. It was originally published as a print map in 1989.

Description

The data represents the relative amount of manure production in the agricultural area of Alberta. It is an estimate of the degree to which livestock production may contribute to nutrient loading, pathogens and odour. The classes shown on the map are ranked between 0 (lowest) and 1 (highest). This resource was created in 2002 using ArcGIS.

Description

This map illustrates the distribution of soil parent material textures in the agricultural region of Alberta. Soil texture is defined by the relative proportions of the sand, silt and clay particles present. Soil textures are identified by classes using the Soil Texture Triangle illustrated below. The Soil Texture Triangle identifies the textural class of a soil at the intersection of the percent sand (x-axis) and the percent clay (y-axis). The percent silt of the soil is the remainder to add up to 100 percent. This resource was created in 2002 using ArcGIS.

Chemical Expense Index 2001

Description

The data represents the relative expense of farm chemicals (herbicides, insecticides and fungicides) in the agricultural area of Alberta. It is an estimate of the degree to which crop production agriculture may contribute to surface or groundwater contamination.Agriculture production that makes greater use of herbicides, insecticides and pesticides in generally considered more intensive. Presenting the relative farm chemical expenses by SLC polygons reveals where the most intensive agricultural production in the province occurs. Chemical use is part of an equation to determine a measure of surface water quality risk. If an area is known to have certain risk factors that would affect not only surface, but groundwater quality as well, a higher chemical expense index ranking in that same area may be of concern. Where risks of surface or groundwater contamination exist, environmental farm planning can help to minimize them.

Description

The data represents the annual total precipitation in Alberta over the 30-year period from 1971 to 2000. A 30-year period is used to describe the present climate since it is enough time to filter our short-term fluctuations but is not dominated by any long-term trend in the climate. Annual total precipitation refers to rain, snow and other forms of moisture such as hail. Annual precipitation is greatest in the mountains and decreases at lower elevations. In the agricultural areas of the province, 50 to60 percent of annual precipitation generally occurs during the growing season, mostly as rain.Precipitation in any month can be extremely variable with the variability of precipitation being greater in southern Alberta than in the Peace River Region and central Alberta. However, long-term (30-year) data provides a reliable indication of what to expect in any given location. Climate information is used as a long-term planning tool, in selecting a location for a farm or planning a...
