This project investigates the effectiveness of using native plant species for revegetation along urban waterways. Five previously revegetated sites along Melbourne's linear waterways were studied. These sites include Diamond Creek, Merri Creek at Blyth Street and Hall Reserve, Plenty River and Taylor's Creek.
Revegetation techniques were studied in order to determine the most successful strategies for urban revegetation. Observational techniques and surveys were used to evaluate the success of each individual project sites.
All sites largely succeeded in achieving their original project aims, which included the use of indigenous vegetation, restoration of wildlife corridors, encouragement of passive recreation and use of regular maintenance. Criteria were used to assess the successful achievement of these aims, and `extra criteria' were developed to evaluate the success of other revegetation goals. The sites largely achieved satisfactory results for the extra criteria.
Findings indicate a direct association between average leaf litter cover and average weed cover. This shows that high priority should be given to control and prevention of weeds through the application of mulch, and the development of strategies to increase leaf litter cover.
Data also establishes that successful revegetation requires adequate planning, site preparation, site maintenance, consideration of landscape values and public awareness. The data enabled the development of recommendations, which can be used in the implementation of successful revegetation projects in the future.
