A key objective of the GreenWay is providing a continuous north south link for flora and fauna from Iron Cove Bay to the Cooks River. The GreenWay is a natural green corridor due to the heavily vegetated freight rail line (now being converted to the Inner West Light Rail Extension) and Hawthorne Canal.
Bushcare sites have been established in the GreenWay to provide habitat and “stepping stones” for local fauna, such as reptiles and small birds.
Wildlife corridors are remnant habitat, regenerated habitat or artificially created habitat that links larger areas of wildlife habitat. Corridors provide a means by which animals and plant seeds can move between larger areas of habitat that are their refuges, within an otherwise uninhabitable environment.
Wildlife corridors provide a mechanism for the reduction or moderation of the adverse effects of habitat fragmentation by facilitating the dispersal of individuals between areas of remaining habitat. This enables individuals to re-colonise habitat patches which have become locally extinct and increases opportunities for long term genetic interchange.
Wildlife corridors play a crucial role in maintaining connections between animal and plant populations that would otherwise be isolated and at greater risk of local extinction. Corridors also provide supplementary feeding habitat for animals. The Cooks River to Iron Cove GreenWay plays an important role as an urban wildlife corridor.
The quality of the corridors as fauna habitat is a critical factor in their effectiveness. A wide corridor of bushland in good condition, with the full diversity and strata of native vegetation, is obviously the best option, and it is important to retain and protect such links where they still exist.
However, even corridors retained in backyards and on road reserves can play a vital role in maintaining connections between fauna populations. The frequency of the corridor may be very low, but the movement of just one or two animals between populations can be critical. Through the GreenWay Project, a concept called the "GreenWay Trellis" encourages local native plantings throughout the GreenWay catchment.
Wildlife corridors and habitat continue to be impacted by residential development. Other pressures include:
