HUN Forested Wetlands foliage cover change predictions by Assessment Unit


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.

Hunter receptor impact variable predictions for forested wetlands landscape class mapped to Assessment Units to facilitate mapping for report maps.


lc_id codes used in this dataset are at variance with landscape class codes used elsewhere. For this dataset and its source lc_id = 1 is Forested Wetlands, lc_id 3.12 is Wet and Dry Sclerophyll Forests

Dataset includes:

HUN_RIV_quantiles_IMIA.csv: Source normalised file that was generated 04/04/2018 containing RIV predictions

HUN_node_HRV.mdb: An MS access db used to extract and reformat the forested wetland RIV predictions to make them suitable for mapping. Note only the table HUN_RIV_quantiles_IMIA_20180404 and the queries lc_01_2042 & lc_03_12_2042 that use this table are relevant to this dataset. All other tables and queries are legacy items and should be ignored!

lc_01_2042_pfc_diff_20180404.xls & lc_3_12_2042_pps_diff_20180404.xls: outputs from above mdb queries for use as attributes in spatial data

RIM_prediction_AUs.gdb: File geodatabase containing Assessment Units with Forested Wetlands RIV predictions appended to the Attribute table. Feature class lc_01_2042_pfc_diff_20180404 as well as other reference spatial datasets.


Created for the facilitation of producing report maps.

Dataset History

The source csv normalised file was ingested into an Access database.

Queries were used to extract and cross-tabulate the Forested Wetlands (lc_id = 1) and Dry/Wet Sclerophyll Forests (lc_id 3.12) predicted change in foliage cover for 2042 (pfc_diff & pps_diff) respectively for the 5th, 50th and 95th percentiles. These were exported to respective .XLS files.

The forested wetland XLS was joined to a spatial representation of the Hunter Asssessment Units using the auid as the join item and exported as a new AU spatial dataset with the forested wetlands RIV data for the three quantiles (F5, F50 & F95) included in the attribute table.

A risk class was created and forested wetland AUs classified according to the following rules.

"minimal risk" : F5 > -0.01 AND F50 >= 0

"more at risk" : F95 < 0 OR F5 < -0.05

"at some risk" : everything that is not "minimal risk" or "more at risk"

Forested wetland AUs on the regulated sections of the Hunter River and Fal Brook (ie downstream of dams) and on the coastal sands in the Macquarie-Tuggerah were excluded from the risk classification and arbitrarily designated "Not represented by RIM".
