Abstract
This dataset was supplied to the Bioregional Assessment Programme by a third party and is presented here as originally supplied. Metadata was not provided and has been compiled by the Bioregional Assessment Programme based on known details at the time of acquisition.
This dataset contains an ESRI shapefile with polygons covering Groundwater Dependant Ecosystems in the Northern Rivers CMA. It is a DRAFT DPI pre-release version.
This dataset has been provided to the BA Programme on the condition that third parties may not reproduce this dataset. Third parties wishing to use or reproduce this data should contact the data provider.
Purpose
Data Status:
This is a preliminary dataset, the project is on going.
Dataset History
Vegetation in NSW of high ecological value having high probability of being groundwater dependent were identified through a process that used current vegetation data, depth to groundwater data, data that showed potential frequency of water use other than surface water based on a continuous 10 year period and expert opinion. High Probability vegetation communities were identified as being of High Ecological Value when they sat within one or more selected datasets. (see below)
Geographic Extent: Northern Rivers CMA
Data sources:
High Probability
-
Vegetation: obtained from OEH
-
Depth to groundwater: modelled data provided by Office of Water Hydrogeologists
-
Potential frequency of water use other than surface water based on a continuous 10
year period : This data set was created by Herbert Hemakumara (Office of Water) using
remote sensing MODIS
High Ecological Value
-
National Parks and State Forests (OEH)
-
SEPP 14 & 26 (Dept Planning)
-
RAMSAR Wetlands (OEH)
-
Marine parks and aquatic reserves (OEH)
-
Identified rain forest communities (OEH)
-
Threatened or endangered species (OEH)
-
Wildlife corridors, Regional Conservation strategies or communities identified as
being significant in various studies (Various Sources)
Positional Accuracy:
The eastings and northings of all points are only approximate.
The shape of polygon features are only approximate.
Data Status:
This is a preliminary dataset, the project is on going.
