Abstract

This document describes a set of high conservation value river and wetland assets
within the Montagu River and Welcome River catchments (Figure 1). It is one of five
reports prepared under the Australian Government Water Fund (AGWF) focussing on
high conservation value river and wetlands identified by the Tasmanian CFEV (the
Conservation of Freshwater Ecosystem Values) framework. The assets described here
are those located in areas likely to be directly affected by decisions made under Water
Management Plans for the Montagu River and Welcome River catchments.
The purpose of this report is to provide a summary of information on the biophysical
characteristics and condition of assets of high conservation value for the purposes of:
Describing the natural values (Conservation of Freshwater Ecosystem Values
(CFEV) ‘biophysical classes’) and current condition of key, high conservation
value river and wetland assets in the catchment.
Listing the priority management issues at each asset, and the priority
management actions for their protection/restoration.
Listing the water-management related issues which need attention at each
asset.
The term asset used in this report refers to either:
a specific wetland – mapped as a shape (or ‘polygons’, in GIS terminology) at
the 1: 25,000 map scale.
a group of adjacent lengths of river channel, made up of individual river
sections (or ‘lines’) mapped at the 1: 25,000 scale.
The biophysical descriptions provided here are based on elements described in the
Tasmanian CFEV framework, supplemented by descriptions derived from focussed
field surveys. The descriptions provide information on:
The natural values (CFEV biophysical classes) at each asset – those
characteristics which are or would be present in the asset under natural
conditions.
The current status or condition of the asset – both as measures of departure
from the natural state and in relation to particular symptoms of condition (e.g.
weeds).
The descriptions target values, condition and management issues associated with:
For river assets: instream and riparian vegetation, fish, benthic
macroinvertebrates, fluvial geomorphology, overall river section and
catchment status.
For wetland assets: within-wetland and riparian vegetation, overall wetland and
proximal catchment status.
