A 'little known' river running between Isleworth and Twickenham needs your vote to secure a major cash injection.

The Duke of Northumberland's River is one of seven nature spots across London vying for a share of £900,000 in the Big Green Poll.

The river's eastern section, which flows from the River Crane beside Kneller Gardens to the Thames in Isleworth, already provides a sanctuary for kingfishers, water voles and other rare species.

But the money would help turn the four kilometre stretch into a haven for other wildlife and make it more accessible for more visitors of the human variety.

Better paths and new signs to help people find the river - which the poll describes as 'little known' - are among the planned improvements, should the project get enough votes in the online poll.

The improvements are part of plans to create a new 10km riverside loop linking the Crane, the Thames and the Duke's rivers.

The eastern section of the Duke's river was built some 500 years ago by monks at Syon Priory, shortly before the dissolution of the monasteries, to divert water to the mills and to feed ponds in the grounds. The ornamental ponds still exist today in Syon Park, which is owned by the Duke of Northumberland.

Rob Gray, chairman of Friends of the River Crane Environment (FORCE) said the Crane Valley Partnership had applied for £175,000 from the Greater London Authority but match funding from Hounslow and Richmond councils would bring the total to about £400,000 should its bid succeed.

"I'm hoping this will act as a catalyst to make some long overdue improvements to the river, which has become quite overgrown and hazardous in some places," he said.

"I would like to see the riverside paths used by 10 times more people and to see improvements to habitats for the kingfishers, water voles and other wildlife using the river."

Should the money be granted, he said the improvements should be completed by March 2016 at the latest.

The £900,000 prize pot for green spaces across the capital represents the second round of the Mayor of London's Big Green Fund.

As well as helping green spaces flourish, it is hoped the investment will improve flood management and open up new walking and cycling routes. The five projects with the most votes will receive funding.

Stanmore Marsh, in the borough of Harrow

Stanmore Marsh, in the borough of Harrow, is among the other six projects competing for the cash bonanza.

The money would be used to create around 3,000sqm of wetlands at the site, helping to prevent flooding and acting as a haven for plants and wildlife.

More than four hectares of land would also be turned into an attractive green open space, and there would be nature trails and opportunities for local schoolchildren to learn about the environment through pond-dipping and other activities.

Voting in the Big Green Poll opened on Wednesday (January 21) and is due to close on March 2. You can learn more about the projects and have your say at https://www.london.gov.uk/priorities/environment/big-green-poll
