Description

The Base Hydrography Single Line Hydrography Network (SLNET) is the Alberta Environment and Protected Areas base SLNET data set. It is an update of the Base Features HydroSLNET in Southern Alberta from orthophoto and various sources of provincial base data. It contains all captured single line representations of hydrographic features. In addition, single line representations of polygonal features and single line arbitrary network connectors are in the file.

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 annual solar radiation in Alberta over the 30-year period from 1971 to 2000. A 30-year period is use to describe the present climate since it is enough time to filter out short-term fluctuation by is not dominated by any long-term trend in the climate. Daily total incoming solar radiation is measured in megajoules per square metre (MJ/m2). Southern Alberta receives the greatest amount of annual global solar radiation with the amount gradually decreasing as you move farther north. However, cropping is successful in the northern (Peace River) area of Alberta because the longer summer day length helps compensate for the less intense solar radiation. Cloud cover in the mountains will reduce the amount of solar radiation received there.The amount of solar radiation received at the earth's surface varies with two factors that depend on latitude: the angle of the sun's rays and the hours of daylight. The distance from the equator, and therefore the intensity of the...

Description

This map displays the risk of soil degradation by water in the agricultural region of Alberta. Water erosion is a concern because it reduces soil quality by removing soil particles and nutrients, and reduces water quality if these particles are carried into nearby water bodies. The map uses five classes to describe the water erosion risk on bare, unprotected mineral soil: negligible, low, moderate, high and severe.This resource was created using ArcGIS, originally published as a print map in 1993 .

Description

This map displays an assessment of soil erosion risk for the agricultural area of Alberta. Loss of protective residue cover through cultivation will increase the potential risk of soil erosion. The vulnerability of the soil to erosion combined with the intensity of cultivation determines the degree to which the soil may be at risk. The classes shown on the map were ranked from 0 (lowest risk) to 1 (highest risk). This resource was created in 2002 using ArcGIS.

Description

This map, created in 2002 using ArcGIS, describes the number of animal and plant species that are at risk in Alberta. 'Species at risk' is a term used by the Committee on the Status of Endangered Wildlife in Canada (COSEWIC) that includes the following categories of plants and animals:Extirpated species - no longer in the wild in Canada.Endangered species - species facing imminent extirpation or extinction.Threatened species - likely to become an endangered species if nothing is done to reverse factors leading to its extirpation or extinction.Species of special concern - species that may become threatened or endangered due to biological characteristics or identified threats.
