The Coastal Restoration project continued to support coastcare groups in both the northern and southern metropolitan regions of Perth, as well as local governments, to undertake environmental restoration in coastal areas. The program continues to contribute to the improvement and maintenance of conditions of coastal ecosystems in the Perth region by both enhancing and maintaining the condition of coastal vegetation.
Core activities such as debris removal, erosion control, weed management and revegetation has seen improved coastal health with over 66 hectares of coastal revegetation works undertaken during the life of the project, and a total of 23,465 plants planted during the 16/17 financial year. This work could not have been possible without the contribution of many hours of volunteer work and the coastal program has been fortunate to have over 2500 volunteers contribute to restoration works in the past year, with over 1500 of those being new volunteers.
Weed management activities are being undertaken to protect coastal biodiverstity against degradation and highly invasive species, and to retain and increase remnant habitat for native fauna. Weed treatment occurred across 25 hectares of coastline and is conducted in areas within and adjacent to coastal restoration sites to ensure minimal invasion of non-native species and site resilience.
During the 2016/2017 year the Coastal Restoration project has removed over 1.3 tonnes of debris from beaches and adjacent areas. We work closely with organisations such as Tangaroa Blue and Keep Australia Beautiful to ensure marine debris data is submitted to national databases, with a focus on improving beach user behavior and increasing awareness of the impact of debris within our coastal and marine environments.
Erosion management has seen methods such as fencing, jute matting and dune brushing undertaken this year, treating over 2ha of coastal land. Revegetation sites are often in variable condition with many affected by wind, waves, vehicles and pedestrians, and the installation of erosion control material results in improved vegetation condition, habitat connectivity, and soil stabilisation.
Communities in our coastal regions are managing landscapes to sustain long-term economic and social benefits for the environment. Engagement with community groups and volunteers has seen Perth NRM facilitate training sessions and workshops for groups, giving support and guidance in restoration practices, such as up-skilling in weed management, weed identification techniques and training in mapping tools and ecological survey techniques. The Coastal Restoration team continue to engage a significant number of schools and corporate groups to the on-ground aspects of the program.
Perth NRM thanks the corporate sponsors who work closely with us on our coastal management projects- Alcoa; BP Refinery; Kwinana Industries Council; Tronox and proAlliance.
