13R.2 SUMMARY OF METHODOLOGY<br />
FOR CONVERSATION SIGNIFICANCE<br />
ASSESSMENT - GREENWEB (continued)<br />
Vegetation within CRZs provide support for riparian lands through the protection and improvement of<br />
vegetation quality and quantity.<br />
All vegetation within these Core Riparian Zones (as identifi ed in Section 2) has been targeted, including<br />
native and non-native species, with the exception of Riparian category 3a (consisting of piped creeks).<br />
For Riparian category 3a the areas identifi ed in Greenweb category 2 is limited to mapped KVCs only,<br />
recognising the signifi cance of these areas within any future restored landscape.<br />
KVCs adjacent to CRZ areas described above have also been included within Greenweb category 2.<br />
These areas provide an increased buffer to CRZ within areas of ecological importance. Additionally<br />
connectivity provided by the CRZ helps to support the KVC area.<br />
Vegetation within riparian areas provides a number of ecological services, including habitat, food<br />
resources, bank stability and sediment / nutrient fi ltration. They also act as microclimates, changing<br />
conditions in small remnant areas to support a variety of organisms as well as providing resources<br />
to nomadic, migratory and nearby resident species (Price et al 2007). Whilst occupying only a<br />
small proportion of the landscape, they support a greater variety and abundance of animal life than<br />
surrounding areas (Catterall et al 2007).<br />
Riparian areas are known to be directly associated with many species. Apart from a wide array of<br />
invertebrates, in <strong>Ku</strong>-<strong>ring</strong>-<strong>gai</strong>, the Eastern Water Skink (Eulamprus quoyii), the Eastern Water Dragon<br />
(Physignathus lesueurii) and a number of frog species are entirely dependant on riparian areas for<br />
dispersal and survival. A number of microbat species, ground dwelling marsupials and the endangered<br />
Powerful Owl (Ninox strenua) 1 depend on riparian zones regularly on a daily and seasonal basis.<br />
The potential for moister environments to withstand temperature rises as associated with climate<br />
change may also play an important conservation role in the future. These areas provide for the<br />
protection of vegetation across the topographical range within the LGA. From 1st order streams,<br />
originating at shale bea<strong>ring</strong> ridges though to 3rd order streams within sandstone gullies and estuarine<br />
environments.<br />

This includes all vegetation, including non local / non native species, within Biodiversity Corridors.<br />
Note that areas of within biodiversity corridors lacking vegetation are mapped within Category 4.<br />
