Restoration of Mt Henry Spit

Restoration works at Mt Henry Spit will manage foreshore erosion, enhance the ecology of foreshore and dryland areas, and provide options for well integrated public access infrastructure such as pathways.

The Mt Henry Spit is situated in the Swan and Canning River system near the point where the Canning River joins the rest of the estuary system. It is an important environmental, cultural and recreational location in South Perth. It is a recognised Indigenous site and part of the largest area of bushland in the City. The area is also used by the public for many passive and active recreational purposes. The surrounding spit is a designated water ski area.

The Spit has experienced degradation and disturbance over time, which has negatively impacted on the ecological function and aesthetic value of the site. The popularity of the neighbouring spit as a water ski area has significantly affected the stability of the low foreshore, leading to erosion.

Mt Henry Spit Restoration

In September 2014 the City, in collaboration with the Department of Biodiversity, Conservation and Attractions (former Swan River Trust) developed a comprehensive restoration plan for Mount Henry Spit to implement an extensive revegetation program and ´╗┐address shoreline erosion and weed inundation.

Over the past few years the City has continued the partnership with the Department of Biodiversity, Conservation and Attractions under the Proactive Riverbank Funding Scheme, undertaking weed control works in accordance with the Mt Henry Spit Restoration Plan 2014 recommendations to prepare the site for scheduled revegetation works. Implemented weed control works included not only chemical but also manual and mechanical methods to maximise eradication of weeds on site, reduce risk of off target spray damage to neighbouring native plants and promote growth of self-seeded native vegetation. In June 2017 all scheduled weed control works were successfully completed. 

The project is being undertaken in accordance with the Mt Henry Spit Restoration Plan 2014. The restoration area includes 900 metres of foreshore from the Mount Henry Bridge, north towards Cloisters Reserve. This includes the dryland area east to the Kwinana Freeway and encompasses approximately 3.6 hectares (ha). These areas are recognised as a Bush Forever site. 

The area has experienced degradation and disturbance over time, which has negatively impacted on the ecological function and aesthetic value of the site. The popularity of the neighbouring spit as a water ski area has significantly affected the stability of the foreshore, leading to erosion. The area is also used by the public for many passive and active recreational purposes.

The City will propagate any plants needed for the restoration of the area in its own nursery. It is anticipated that the restoration will lead to long-term erosion control, promote species diversity and provide habitat for native fauna.

This project will be completed in two phases. Phase one ran from June 2017 and was completed in June 2019. Phase two begins in February 2020 and is expected to finish by the end of the year.
