    Coal Agreement feature class contains provincial extent polygon features representing Coal applications, agreements, leases, and licences, with varying term dates and conditions. These applications and subsequent agreements give the holder the right to explore Coal.

    The data represents the occurrence of saline soils in the agricultural area of Alberta. A Saline Soils is a non-alkali (pH less than 8.5 and exchangeable-sodium less than 15%) soil containing soluble salts in great enough quantities that they interfere with the growth of most crop plants. This resource was created in 2002 using ArcGIS.

    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.

    This data was produced under contract for Alberta Forestry and Parks, Forest Management Branch in 2015-2016. Variables used were elevation, aspect, slope, landscape mesotopography (e.g. ridge, upper slope, etc). DEM was used where there was no LiDAR coverage, with a resolution of 25 m2 pixels. Canopy height was not included in this model because it was a product generated by LiDAR. In these files there is a report assessing accuracy of the models compared with field observation data. detailed accuracy data by township is available upon request.

    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.

Variables used were elevation, aspect, slope, landscape mesotopography (e.g. ridge, upper slope, etc). Where there was LiDAR coverage, resolution was 1m2 pixels. Canopy height was included in this model as a product generated by LiDAR.

    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 .

    The Alberta Regeneration Information System (ARIS) requires a unique identifier assigned to a cutblock to enable tracking within ARIS. This number is generated from a point roughly derived from the centre of the cutblock. The number is a concatenation of the point's legal description plus a grid cell number. The format is MRRTTTSSGG where M - Meridian, RR - Range, TTT - Township, SS - Section, GG - grid cell. The MRRTTSS information is derived with reference to the Alberta Township System. The grid cell is derived from a 10 by 10 grid that is overlaid on the section that the centre of the cutblock is contained in. Grid cells are numbered between 00 - 99 with the grid origin at the bottom left corner of the section and anchored to the centre of grid cell 00. The first digit represents the grid column and the second digit is the grid row of the 10 by 10 matrix. Note that in some cases a letter may be appended to the end of the opening number where an opening number had to be split between two cutblocks for some reason. For example, cutblocks may have the same basic opening number but one is differentiated from the other with one having an A and the other having a B appended to the end of the base opening number.This dataset contains all the potential opening numbers in the Green Area of the province, either as a whole or by Forest Management Unit (FMU).

    This map displays the distribution of organic soils in the agricultural region of Alberta. Organic soils consist of layers of material with greater than 30 percent organic matter and a total thickness of greater than 40 cm. Organic soils are generally saturated with water for most of the year unless drained. Saturation inhibits decomposition and encourages continued accumulation of organic material. Drainage of these soils can result in a rapid increase in decomposition and a reduction in the thickness of the organic material. This resource was created in 2002 using ArcGIS.
