Relative Forest Growth Stage Classification

This layer contains the relative forest growth stage classes. The classification is based on Eucalypt growth stages identified by Max Jacobs (Growth habits of the eucalypts, 1955) and described in terms of the relative contribution of irregular to regular to regrowth forms to the total crown cover. The data has been collected to SFRI standards for the old growth forest mapping program.

Data Temporal Coverage: 1992-01-01 to 2017-12-31
Geospatial Coverage 141,-39,150,-34
Geospatial Scale 1:25,000
Geospatial Accuracy No attribute accuracy assessment has been undertaken, however based on attribute checking procedures: 1. Polygons GT 1ha: an error of 1 in 50 (approximately 98% accuracy) 2. Polygons LT 1ha: an error of 1 in 20 (approximately 95% accuracy) Precision: 10m to 100m Determination: Forest growth stages are registered to 1:25,000 and 1:100,000 base maps from aerial photography ranging in contact scales from 1:20,000 to 1:40,000. Positional accuracy is based on drafting pen thickness, base map accuracy and the nature of the boundaries mapped. Map errors of 0.5 to 3mm are reasonable (ie 12.5m to 300m).
