Riparian Reconstruction

  • Damien Leeding Park (map)

Riparian areas are often a focus for restoration as these regularly disturbed systems are frequently degraded by erosion, weed infestations and a higher edge to area ratio. When these systems are highly degraded and require major works to stabilise an area, often the go-to solution is rock which provide limited biodiversity outcomes.

On this field trip, participants will visit two sites on the Gold Coast where reinstating bank stability has been essential and balanced with a number of biodiversity objectives. One site is a freshwater system and is an established 10 year old project while the other has undergone recent works and is a tidal system. The site participants will visit is on the beautiful Currumbin Creek and is, a 2.4 km stretch of creek that has been stabilised by reconstructing the stream bed and ustilising a number of approaches and materials, geomorphic insights and the restoration of 10.4 ha. Works have involved engineers, multiple Council departments, the local community group that formed in response to works and adjacent landholders. This area has successfully survived multiple high flow events and two large floods. The second site has recently been reconstructed and as a highly visited park required a safe and stable foreshore while ensuring the banks were not breached impacting the lake. In addition to stabilisation, water quality improvements, mangrove, fish and crab restoration, approaches taken on this site to reduce the velocity of water on the foreshore by manipulating hydraulic forces during flood and tidal events, is show casing alternatives to simply installing rock. At both sites, geomorphologists, catchment and restoration experts as well as community members will be on hand to answer any questions.

Morning tea in the park adjacent to Currumbin Creek and the lake and lunch on the foreshore of the Coomera River, Damien Leeding Park.

Cost: $45 per person. Includes travel, packed morning tea and lunch and restoration guides.

Date and time: Friday 28th September 08:00 – 17:00. Depart and return from/to UQ.
