Abstract
The dataset was derived by the Bioregional Assessment Programme from multiple source datasets. The source datasets are identified in the Lineage field in this metadata statement. The processes undertaken to produce this derived dataset are described in the History field in this metadata statement.
This dataset contains polygon and line shapefiles representing the Gloucester terrestrial (both a multipart and singlepart version) and riverine Landscape Classes respectively. It also contains KMZ exports of these features.
Note: This differs from previous versions in that the extent was extended to the Gloucester AE boundary (previously the extent was to the PAE) so the discontinuous river lines that weaved in and out of the PAE boundary could be wholly included.
The polygon landscape Classes are as follows.
Terrestrial (polygons)
Forrested Wetlands
Freshwater Wetlands
Rainforests
Dry sclerophyll forests
Wet sclerophyll forests
Saline wetlands
(Non-GDE) Native vegetation
Plantation or production forestry
Dryland agriculture
Irrigated agriculture
Intensive uses (includes mining)
Note forestry that selectively logs native forests is included in the "(Non-GDE) Native vegetation" class rather than the economic "Plantation and production foresstry" class.
Dataset History
The terrestrial Landscape class polygons are sourced directly from the two input polygon source datasets and clipped to the Gloucester PAE.
GDE landscape classes derive directly from the source NSW OoW GDE layer's Keith Form attribute, though the "Riverine Forests" Keith form are combined with the "Forested Wetlands" LC and the "Mangrove Swamps" and "Saltmarshes" Keith Forms are combined to form the "Saline Wetlands" LC .
The remaining non-GDE terrestrial LC polygons are mainly sourced from the ACLUM catchment landuse from the PRIMARY V7 classification, and retain the source class names except that "1 Conservation and natural environments" is rename the "non-GDE Native Vegtation" LC. A further exception is the "Plantation and Production Forestry" LC. This is derived from the SECONDARY_V7 classification where:
"SecondV7" = '2.2 Production forestry' OR "SecondV7" = '3.1 Plantation forestry' OR "SecondV7" = '4.1 Irrigated plantation forestry'
The Riverine LC lines are derived directly from the Rivertypes source dataset
Note for the 2016 March 9 IESC Deep Dive for GLO was necessary to tease out the Keith Forms of the "non-GDE native vegetaton" Landscape class in order to generate areal statistics for endangered species habitats. These were sourced from the Greater Hunter vegetation mapping. This sub-LC differentiation is retained in this dataset
