Background Information
Queensmere Pond, located on Wimbledon Common, is a historically significant waterbody that had suffered from years of ecological degradation. The pond faced extensive siltation, poor water quality, eroded banks, and habitat loss, issues that were further compounded by unrestricted dog access and lack of marginal vegetation. Commissioned by the Wimbledon and Putney Commons Conservators, the restoration aimed to rejuvenate the pond’s natural function, enhance biodiversity, and create a safe and visually pleasing environment for both wildlife and the public. The restoration was part of the wider “Rewilding Queensmere” initiative.
Scope of the Project
The Queensmere restoration included comprehensive habitat, water quality and access improvements:
Installation of pre-planted coir roll revetments to stabilise banks and create habitat. Construction of a new reedbed using bioengineering techniques. Desilting of the pond, with reuse of silt material behind new revetments and creation of island. Formation of a wetland shelf using biodegradable fabrics. Creation of amphibian banks and a silt trap to encourage species colonisation and improve water quality. Installation of a viewing platform for public access and wildlife observation. Construction of dog access beach and headwall improvements. Seeding and planting with native species to enhance ecological value. All works were carried out in a sensitive and sustainable manner, with minimal disruption to the site’s character and ecology.
Our Solution
Aquamaintain Ltd mobilised a skilled team and specialist plant to deliver the project efficiently and safely. The pond was partially drained, and a water management system was installed to allow phased desilting. A fish rescue was carried out using seine nets and electrofishing equipment and fish were rehomed. Long reach excavators working from designated matting areas along with our Truxor amphibious machine removed silt, which was then used to backfill new marginal planting zones.
Revetments and an island were constructed using Nicospan, hazel faggots, coir rolls, straining wire, and gripples fixed to anchor posts. A silt trap and amphibian bank was created at the pond’s inlet to collect incoming suspended solids and provide additional niche wetland habitat within the pond area.
The viewing platform was constructed from long-life, low-maintenance Hahn recycled plastic legs, with oak decking and handrails offering safe and sustainable public access.
Works were coordinated under strict environmental management protocols, including daily toolbox talks, pollution prevention controls, and adherence to biosecurity policies.
