Lower Duke of Northumberland's River Improvement Project
The project is one of seven projects across London that received funding from the Mayor's Big Green Fund II in March 2015. The CVP was awarded £157,500, whilst match funding is provided through S106 money from the London Boroughs of Richmond and Hounslow, Heritage Lottery Funding through Green Corridor and SITA Trust funding through the Zoological Society of London.
Major improvements will be made to the lower Duke of Northumberland's River, where it flows through Twickenham into the River Thames. A new ten kilometre circular riverside walk linking the Crane, Thames and Duke’s Rivers will be created (see map below). In addition, improvements will be made to marginal habitat areas and, where appropriate, in-stream works will be undertaken.
A project summary is available for download.
- Eel passes: One of the first activities that took place on this project was the installation of two eel passes in June 2015 by ZSL. One at Kidds Mill Sluice and another at Mogden Sewage Treatment Works. Volunteers recorded the number of elvers passing through the structures until the end of September. After only four days, the first elvers were recorded. Up to the end of September over 600 elvers have been counted using the two new passes to enter the Crane catchment.
- River clean-up: The Conservation Volunteers (TCV) have been active during the last few months in cleaning the Duke's river. Tons of rubbish have been hauled from the river.
- Aquatic macro-invertebrate sampling: Make Natural Ltd (Ecological Services) was commissioned to undertake a macro-invertebrate survey on the Lower DNR to get a baseline understanding of the invertebrate population for the river. The report is available for download.
- New pathway opens: The new pathway along the upper part of the Lower DNR - from Kneller Gardens to the A316 - opened in February 2016.
- Work at Silverhall Park: The re-opening of the northern part of Silverhall Park in Isleworth, abandoned and closed off around ten years ago, has started with a small group of volunteers, led by Green Corridor. Six days of work were undertaken during March and a further six days is scheduled during May. Works include opening pathways and dead hedge laying to improve the environmental value of the site.
