Comments<br />
Fencing and providing alternative shade, as well as promoting revegetation/regeneration of riverbanks with native indigenous trees, shrubs and grasses can reduce the impact of<br />
stock in the riparian zone. By then employing a controlled ‘pulse grazing’ technique, weeds can be effectively controlled. <strong>The</strong> impacts of stock permanently grazing in the riparian<br />
zone can be severe and through grazing and trampling can:<br />
• deplete the banks of reinforcing vegetation making banks more prone to erosion<br />
• prevent young vegetation from growing<br />
• directly expose bank material to erosion<br />
• compact soil reducing infiltration, root growth and overall plant production<br />
• diminish the overall diversity of plant species and provide more favourable conditions for weeds, and<br />
• contribute excessive nutrients to waterways by concentrating nutrients derived from cattle dung.<br />
[Lower Wallamba River rivercare plan]<br />
<strong>The</strong> Department of Lands is currently conducting a comprehensive Crown Lands assessment. This review could see the development of terms and conditions attached to permits<br />
and leases to ensure the protection of ecologically significant riparian areas. It is recommended that based on the results of this assessment, the complete removal of stock from<br />
these areas in the foreshore Crown Reserve * be considered.<br />
Implementation of the Lower Wallamba River rivercare plan (action M.6.1) will also aid considerably in achieving this management objective.<br />
* Crown Reserve extends approximately 30 m around the foreshore of the <strong>Wallis</strong> <strong>Lake</strong> estuary<br />
