Description

The Alberta Vegetation Inventory (AVI) is a standardized digital forest inventory product that is used to spatially identify the type, extent and condition of forest vegetation. The AVI is also a detailed, spatially-explicit standard to assist in the decision-making process for forest management planning, wildfire management, wildlife habitat classification, ecological classification and integrated resource management activities. The establishment of AVI standards helps ensure data quality, consistency, and compatibility with Government of Alberta forest inventory database architecture, as the responsibility to acquire AVI data is shared between forest management agreement holders and the Province.

Revising the use of age-age correlation for conifer tree breeding in Alberta

This paper describes an attempt to develop correlation prediction equations using data from Alberta species grown in the Alberta environment. It changes the form of the equation used by Lambeth by... More ≫

Description

This paper describes an attempt to develop correlation prediction equations using data from Alberta species grown in the Alberta environment. It changes the form of the equation used by Lambeth by inputting the age difference between measurement and rotation ages as a predictor variable as opposed to an age ratio that Lambeth uses, which inadvertently equates the latest field measurement to a rotation age measurement. it should be noted that this paper is not intended to increase the size of the age-age correlation compared to what could be obtained by Lambeth. it is only intended to provide an empirical procedure of obtaining a correlation that is biologically meaningful and partly related to the species and trials for which the genetic gain is being sought.

The results of the surveys reported here provide a summary of the biotic and abiotic agents affecting cones, seedlings and trees, gives a distributional summary of damage agents according to... More ≫

Description

The results of the surveys reported here provide a summary of the biotic and abiotic agents affecting cones, seedlings and trees, gives a distributional summary of damage agents according to plantation sites established within the province up to 1994, and indicates the relative importance of each agent. The report also provides a listing of unpublished technical reports that resulted from the work described here and can be referred to for further details where necessary.

Patterns of optimal growth for white spruce provenances in Alberta

Description

This paper describes the pattern of genetic variation for growth potential among white spruce provenances in Alberta. It uses total height and diameter at breast height at 27-years from seed to... More ≫

Description

This paper describes the pattern of genetic variation for growth potential among white spruce provenances in Alberta. It uses total height and diameter at breast height at 27-years from seed to identify provenance differences in relation to latitude and elevation of weed origin. Latitude and elevation are the main variables that adequately describe climatic variability in Alberta.

Patterns of optimal growth for lodgepole pine provenances in Alberta

Description

This report describes results from measurements of 15 year height and diameter at breast height made on a series of provenance trials comprised of 23 Alberta populations planted on 0 test sites... More ≫

Description

This report describes results from measurements of 15 year height and diameter at breast height made on a series of provenance trials comprised of 23 Alberta populations planted on 0 test sites across the province. Although currently the age of these trials ranges from 19 to 24, only 15 year data for height and diameter are available for all trials.

Description

This information paper describes the forestry industry in the Peace River region of Alberta, outlining its historical development and current state. It examines the industry's economic impact, employment figures, and the evolution of harvesting and manufacturing practices. The paper also discusses future development opportunities, including the utilization of aspen poplar, and addresses environmental concerns related to watershed protection, wildlife habitat, and recreational uses. It concludes by emphasizing the importance of sustainable resource management and increased public involvement in land allocation decisions for the region's forest lands.
