We are pleased to share that we have secured funding through the national Trees for Climate programme, working with Thames Chase Community Forests, to restore and enhance Tong Farm. Our aim is to maintain a farmed landscape that is of greater benefit to our local wildlife whilst also improving access.

Ponds, troughs and trees

Project Summary

The work includes:

  • 10 benches will be installed across the farm to allow you to sit awhile and enjoy this piece of countryside that we all cherish.
  • A total of 16,000 trees will be planted to vastly improve the field edge habitat and provide nectar and food for invertebrates, birds and small mammals.
  • 9600 trees will make up 1.5 kilometres of mixed native hedgerows and a further 5000 trees planted in enclosures.
  • A final 100 trees will be planted across the farm to create more of an open wood pasture habitat, whilst retaining key viewpoints across the landscape. As these trees mature, they will provide a home for wildlife as well as shade for livestock.
  • Installing and planting fenced enclosures with dense scrubby tree species in the lower fields to increase species diversity and provide valuable habitat for scrub-reliant species.
  • Flushers Pond will be drained early in January so it can be mechanically desilted. An appropriate outflow system will also be installed to allow the duck weed to be skimmed off and a filtration pond dug out, before being refilled in time for the amphibians to return in early spring.
  • Replacing 8 kilometres of dilapidated stock fencing and installing water troughs in all fields to allow us to graze all farm fields.
  • The sections of the brook that runs through the farm fields will see considerable reprofiling of its banks to slow the flow of water and create marginal wetland areas along the lower fields.

The livestock will be taken off-site prior to works commencing and will return once fields are fenced.

More information

As work progresses we will update this page with further information on our progress and the areas where we will be working. If you are visiting the site, please look out for our poster boards that will also have up-to-date information about the work and any effects this may have on access.

In the intial stages of the project our contractors will be using some heavy machinery and may require a few areas to be temporarily fenced off. Your safety and enjoyment are very important to us and our contractors, so please observe all signs and directions given by the team and on the posters. We aim to minimise the effects of our work and will do all we can to reduce noise and disruption.

We'll keep as many paths and spaces open as we possibly can. Please be aware that some of the paths may become more muddy than usual and therefore may be slippery in places. We will also put any important information for visitors on the website - we suggest you bookmark this page.

Thank you for your understanding.

Blog

Throughout the project we'll be keeping a blog on this page, which will showcase the work we are doing and the progress made.

Ponds, troughs and trees

The pond desilting is now complete, and the filtration pond has been shaped with an excavator. Flusher’s pond is clay lined and the original banks are quite steep, so the contractors have dressed the edges to create marginal, niche habitat along the edges which makes it more favourable for wildlife. The outflow for the pond is scheduled to arrive next week so will be installed once it arrives and the pond will then be refilled to its capacity.

The new water troughs arrived this week and will be installed in mid-March. As the farm will be grazed with cattle and sheep, we will be replacing the small sheep water troughs with larger capacity troughs suitable for both cattle and sheep. We will also be installing water troughs in the fields that currently have no source of water for livestock which will enable all fields to be grazed.

All this year’s hedgerows and enclosures have been planted, and the field standards are being planted and guarded over the next couple of weeks. We have also been generously donated five disease resistant elm trees from Elms4London which are also being planted as field standards. The species being planted as field standards are: Field maple, Pedunculate oak, Sessile oak, Small-leafed lime, Wild Cherry, Hornbeam, Wild service, Native black poplar, Scots pine, Elm and Walnut. The hedgerows have been planted with a mixture of 14 different native hedgerow species, and the enclosures have been planted with a mixture of 28 different native species, predominantly scrubby species.
