Forest & Vegetation Inventories

Alberta Vegetation Inventory (AVI) Crown Polygons

Identification Information

Abstract

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 is a compilation of Crown AVI.

The AVI provides detailed information to assist in the decision-making process for;

  • forest management planning,
  • wildfire management,
  • wildlife habitat classification, and
  • integrated resource management activities.

AVI standards were developed to ensure data consistency. This dataset consolidates all Crown AVI into a single feature class.

This dataset is a compilation of the original blocks of Crown AVI data collected using aerial photography dating between 1987 and 2008. A variety of standards was used to collect the original blocks of data that were then merged. This dataset is considered to be valid for use at a scale of approximately 1:20 000.

Alberta Vegetation Inventory (AVI) Crown Cutblock Polygons

Identification Information

Abstract

The Post Inventory Cutblocks for Crown Forest Management Units is a preliminary data set of harvested areas on Crown land with attributes consistent with the Alberta Vegetation Inventory (AVI) 2.1.1 specifications. The Forest Management Branch is responsible for the creation and maintenance of these boundaries for Crown Forest Management Units (FMU’s).

This dataset consolidates all Crown post inventory cutblocks into a single feature class. The post-inventory cutblock updates identify those areas harvested after the inventory date. It is important to identify those areas where the forest cover has been altered and/or removed. It provides supplementary information to the AVI repository to assist in the analysis and decision-making process for;

  • forest management planning,
  • wildfire management,
  • wildlife habitat classification, and
  • integrated resource management activities.

This dataset maintains a consistent format for spatial features and attributes.

This dataset does not contain cutblocks historically managed by the Crown that are outside the current extent of Crown-managed FMU’s. Harvested areas already captured in the AVI dataset are removed from this post inventory data.

Note that the associated AVI data is available as a separate feature class, Alberta Vegetation Inventory (AVI) Crown Polygons, that is distributed with the Crown cutblocks. The extent of the Crown AVI dataset does not exactly coincide with the extent of the Crown Cutblocks dataset.

Central Parkland Vegetation Inventory (CPVI) Polygons

Identification Information

Abstract

The Central Parkland Vegetation Inventory (CPVI) Polygons is a dataset that was created to capture vegetation information for the Central (Aspen) Parkland Natural Subregion in Alberta.

The Parkland Natural Region covers approximately 10% of the province and acts as a broad transitional area between the dry grasslands and the moist boreal forest. This region is characterized by:

  • productive soils,
  • moisture levels, and
  • climatic conditions conducive to agriculture.

The vegetation cover is a mosaic of:

  • aspen woodlands,
  • wetlands,
  • fescue grassland, and
  • riparian areas.

The Central Parkland Natural Subregion is located in east-central Alberta. Other parkland subregions are located in the Foothills and the Peace River areas.

The Central Parkland Vegetation Inventory (CPVI) Polygons is designed to be a vegetation / land use database for the Central Parkland Natural Subregion. The extent of the Central Parkland Natural Subregion was described by Strong and Thompson in The Ecodistricts of Alberta, 1995. This database is intended to be utilized by all agencies involved in land management.

Grassland Vegetation Inventory (GVI) Geometry (Polygons, Lines, Points)

Identification Information

Abstract

The Grassland Vegetation Inventory (GVI) represents the Government of Alberta's comprehensive biophysical, anthropogenic and land-use inventory of the southernmost portion of the province's White Area. The compilation of the inventory commenced in 2006 in the southeast corner of the province using digital colour-infrared stereo photography. Data capture has proceeded north and west.

The GVI is intended as a replacement for the Native Prairie Vegetation Inventory (NPVI) that was completed circa 1993. The GVI product is a more comprehensive and detailed geospatial representation of land cover that is intended to meet a multitude of business needs integral to land-use planning and management in Alberta. It should be stressed that the GVI is a biophysical and land-use inventory rather than a purely vegetation inventory. At its core, it is comprised of ecological range sites based on soils information for areas of native vegetation and general land use for areas of non-native vegetation, namely those associated with agricultural, industrial, and residential developments.

Landscape Polygons are the basic map units in the GVI digital product. These polygons represent interpretations of relatively uniform biophysical or anthropogenic areas. The characteristics of Landscape Polygons are captured as records in the Sites table. The GVI site type classification is captured under the Site Types column in the Sites table to a maximum of four site types per Landscape Polygon. The GVI site types and their associated information plus the data capture methodology are described in the Grassland Vegetation Inventory Specifications.

GVI projects were initially funded under the Base Data Acquisition component of the Land-use Framework program, which represents the Alberta Government's comprehensive and integrated approach to land use planning and management. The primary funding agency is Alberta Environment and Parks.

The GVI data, status map and specifications document are available from Alberta Environment and Parks, Government of Alberta.

Native Prairie Vegetation Inventory (NPVI) Polygons

Identification Information

Abstract

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 database covers the:

  • original Public Lands Southern Region of 1993,
  • the Grassland Natural Region,
  • the Alberta Environmental Protection Prairie Corporate Region of 1998, and
  • the 2001 Foothills and Addition / Crown Update.

The purpose of the project is to complete classification to a quarter section resolution for native prairie vegetation percent cover within the Grassland and Foothills Fescue Natural Regions in southern Alberta.
