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.

Ecological Land Classification (ELC) is an approach which endeavours to subdivide the landscape into significant ecological units and to organize complex interrelationships into identified geographical areas with similar properties. It is a hierarchical system that captures information at the following scales as per the Ecological Land Classification and Evaluation Reference Manual (1980): Ecoprovince - >1:3 000 000 Ecoregion - 1:1 000 000 - 1:3 000 000 Ecodistrict - 1:250 000 - 1:1 000 000 Ecosection - 1:100 000 - 1:250 000 Ecosite - 1:10 000 - 1:20 000 Ecoelement - 1:1 000 - 1:5 000. Note that the upper two levels are referred to as Natural Region and Natural Subregion in the more recent Ecological Land Classification reports. There are also some variations in this hierarchy for individual study areas. The data is available as TIFF image files packaged together with the reports and other supporting documents divided alphabetically.

The Native Prairie Vegetation Inventory (NPVI) Polygons is a quarter section-based vegetation inventory that covers the southern part of Alberta. The native prairie is defined in the Native Prairie Conservation Action Plan as an area of unbroken grassland or parkland dominated by non-introduced species, and an area of previously broken grassland that has reverted back to natural vegetation (30 to 60 years). The Native Prairie Vegetation Inventory extends beyond the Grasslands Natural Region to include data for adjacent areas, such as the Cypress Hills. In addition to the Grassland Natural Region, the Native Prairie Vegetation Inventory (NPVI) Polygons include areas that belong to the Foothills Parkland, Central Parkland, Montane, Dry Mixedwood Boreal and Lower Foothills Natural Subregions.

This dataset defines the ecological areas of Alberta known as the Natural Regions and Natural Subregions, as defined in 2004/2005. This dataset is intended to allow for the stratification of the province of Alberta based on ecological criteria. Natural Regions are the largest mapped ecological units in Alberta's classification system. They are defined geographically on the basis of landscape patterns, notably vegetation, soils and physiographic features. Natural Subregions are subdivisions of a Natural Region, generally characterized by vegetation, climate, elevation, and latitudinal or physiographic differences within a given Region.The intended scale of use of this product is 1:250 000. This version is 2005 Final. Linework changes from the previous Natural Subregion delineation are due both to better information and refined subregion definitions. Note that the Athabasca Plain subregion has been moved into the Boreal Natural Region and that the Boreal Highlands has now been split into Lower and Upper. There is an accompanying report, published 2006: https://albertaparks.ca/media/2942026/nrsrcomplete_may_06.pdf

The Primary Land and Vegetation Inventory (PLVI) is a photo-based digital inventory developed to identify the type, extent and conditions of vegetation in the forested and parkland areas of the province of Alberta. This includes portions of both the Green and White areas of the province. It will include areas of the province extending north from the extent of the Grassland Vegetation Inventory (GVI) and will include areas where the detail and expense of Alberta Vegetation Inventory (AVI) are not warranted, or time and resources are limiting constraints. Ecological site phase (ecosite phase) is the main level of classification used in PLVI. A polygon may be attributed with up to 3 ecological site phases, depending on complexity and extent. PLVI captures range site attributes only within the Central Parkland Natural Subregion. The most up to date ecological site phases can be found in the Plant Community Guides. Guides are broken into individual Natural Subregions. See the Cross Reference Section for additional information.

The Alberta Vegetation Inventory (AVI) is a photo-based digital inventory developed to identify the type, extent and conditions of vegetation, where it exists and what changes are occurring. This dataset consolidates all available AVI into a single feature class.This dataset is produced for the Government of Alberta and is available to the general public.

The mountain pine beetle (Dendroctonus ponderosae Hopkins, MPB) is native to western Canada. It attacks all pine including lodgepole, limber, whitebark and jack pine. Over the past 40 years the range of mountain pine beetle has expanded, possibly due to changes in the area of climatically suitable habitat. Known Limitations: The areas surveyed each year can be different and therefore year over year comparisons may be difficult. the surveyors do not do ground truthing for all disturbances identified, therefore it is not guaranteed that all of the disturbances are caused by MPB. the surveyors do not necessarily map tree patches less than three red trees and therefore the dataset may not include all MPB killed trees. 'grey' attacked trees are not captured. the surveyors attempt to distinguish between 'new' faders and 'old' faders but the accuracy of this distinction is not guaranteed and therefore the data may reflect several years and several generations of MPB attack. Beetle year is August 15 of current year - August 14 of following year. This dataset contains data from 1975 to 2010. Data from 2011 onward is available as a separate dataset.
