Sparks Road Reserve

TERRAMULCH GROUND MAT PLANTING

Sparks Road – Wetland Restoration


Design and Planning – Christchurch City Council

Main Contractor – GSL

 

Purpose: The Sparks Road wetland was designed to help remove the sediment from the stormwater before it enters the Heathcote River.

With the increasing demand for the residential development of land in suburban and semi-rural areas of Christchurch, challenges around erosion and sediment control are faced and met head-on by the Christchurch City Council. This project shows not only forward planning with erosion and sediment considerations but also the integration of revegetation and regenerative strategies to create a beautiful aesthetic wetland to enhance the local community.

Terra Mulch was used on this project initially for plant establishment and weed suppression, however, it soon became clear that the Terra Mulch provided excellent ground stabilisation and a solid substrate for the contractors to work on in challenging Winter conditions. Within a month or two the wool in the Terra Mulch binds to the soil, providing excellent filtration of sediment during rain events. GSL mentioned numerous times about the clearer discharge of water coming from the area covered by the Terra Mulch. Another significant advantage of using Terra Mulch is the release of nutrients, such as nitrogen, into the soil as the matting degrades, acting like a fertiliser for the plants, increasing growth and survival rates.

There are many benefits of considering locally manufactured products in today’s climate and especially when a product like Terra Mulch utilises such a great renewable and biodegradable resource – Wool!

As environmental considerations are at the forefront of these projects now and in the future, proven biodegradable solutions like Terra Mulch become the obvious first choice.
