Growth and Yield dataset is a provincial data set that comprised of Permanent Sample Plots (PSP). Researchers such as GY modellers and those wanting to know the position of all samples will use the all status view to better understand the spatial distribution of historic measurement data including samples that are currently destroyed or inactive

Additional Information

Purpose

To show the location for Researchers such as GY modellers and those wanting to know the position of all samples will use the all status view to better understand the spatial distribution of historic measurement data including samples that are currently destroyed or inactive. PSPs data was created to provide information on rates of growth of existing forest, mortality, and changes in stand structure from stand establishment to maturity or cutting age. PSP data is also required to develop yield tables and to provide the basic information necessary for the development and calibration of growth and yield models. The TSP data is used in the development of the Variable Density Yield Prediction (VDYP) model to fit yield functions for stands of all ages and to provide implied growth rates for mature stands with inadequate PSP coverage.

Data Quality
Lineage Statement

Originally the growth and yield data were collected on field forms and then key punched into the computer in Standard Edit Format (ASCII flat file). Currently the data is collected from the field using Handheld computer, validated using Sample Plot Tools and loaded to the GYS Oracle database.
