Lineage

An assessment of the extent of urbanisation overlying or adjacent to freshwater-dependent ecosystems in Tasmania was undertaken using the TASVEG data layer (Version 0.1 May 2004). TASVEG codes denoting urban and semi-urban development: Ur (rural miscellaneous), Uc (built-up areas) and Ue (permanent easements), were selected from the TASVEG data layer to create an urbanisation base data layer.

An urbanisation score was assigned to river sections using rules provided below.

Data limitations

As per the TASVEG data set.

Assigning values to ecosystem spatial units

Using the urbanisation spatial data layer, each river section was assigned a score (RS_URBAN) indicating presence (0) or absence (1), based on whichever was present along the majority of the river section length.
