New trees in the orchard and field guards

Twenty new fruit trees have been planted in our traditional orchard. Orchards are a valuable habitat in their own right, providing nectar for invertebrates as well as providing fruit, so the expansion of its size is of great benefit to local wildlife.

All the field standards are now planted and have been guarded with robust, locally sourced, sweet chestnut post and rail, which will stand up to cattle scratching against them whilst protecting our field trees from browsing, whilst they establish over the next couple of decades. The field standards will, in decades to come, provide valuable shade for livestock as well as diversifying the field habitat and maintaining open pasture.

Outflows and Wetlands

This past week saw the installation of the pond's new outflow. The old one was dilapidated and leaking so the new outflow will provide a more consistent water level in the pond. The design also allows us to skim off the top of the water to prevent duckweed from accumulating. Now the outflow is in place, the water volume should increase over the next few weeks. There’s still a bit of work still to do around the perimeter of the pond and the filtration pond, and some tidying to be done over the next week.

The wetland works have also commenced this past week, with the shape of the smaller wetland area along the Kyd brook now profiled. The larger wetland is located in the middle of the farm away from footpaths and there is also considerable bank reprofiling being undertaken along the long, canalised section of the Kyd brook that runs through the farm fields. These works will create more wetland areas along the valley of the farm, will hold water back during periods of heavy flow, and also mitigate flood risk downstream by holding water. The smaller wetland, located beside the footpath, will have a leaky dam either end to capture and hold the water, effectively creating a slow-moving area of water for wildlife, and the top of the bank between the stream and the wetland will be dead-hedged to prevent dogs from disturbing the wetland.

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.

Fencing and Desilting

The field that runs along the railway line is now fenced. The gap between the field fence and the railway chain-link fence will be planted up with predominantly scrubby species, to eventually screen the railway lines and create valuable field edge habitat along that boundary. The footpath fence line has also been laid as a hedge this winter, which opens up the view across the field whilst also creating a denser hedgeline for wildlife.

On the topic of hedge laying, the work to the hedge along Soldier’s Field is now complete. Laying the hedge encourages vigorous, dense regrowth, which is ideal habitat for birds, small mammals and invertebrates. The hedge will be maintained at the height it is, to provide open views across Soldier’s field from the footpath.

After a delay with the pond works due to the adverse weather conditions, the pond desilting is now well underway. The silt is being spread in Long Field and will be muck spread in early spring. The amount of rain the past few weeks has meant the ground is looking quite rutted at the moment, but this will all be levelled off when the last of the machinery leaves the work area.

Cattle and fencing

With Cooper’s Field now fenced, the cattle were moved over from Pond Wood Field at the end of January. Coopers Field is over 8.5 hectares in size, the largest field on the farm, so they have a lot of space to roam. They were joined this week by the flock of sheep that were previously in Long Field. The livestock can usually be seen from Botany Bay Lane or the footpath running along the school boundary.

Wimpey’s Field, the field that can be seen from the footpath beside the brook & railway line, has now been refenced too and will be grazed in the coming weeks. The fenced-off section in the field that can be viewed from the footpath is a scrub enclosure. This area will be planted with predominantly scrub species, creating a dense thicket for birds to nest. Eventually livestock will be able to shelter in amongst the scrub, and the diversity of tree species will be increased on the farm.

Soldier’s Field has also now been completely refenced and just requires water trough installation before livestock can be sent out. The natural regeneration of trees along the footpath has been laid as a hedge. Doing so creates a dense boundary which is much more valuable to wildlife, whilst also opening up the view across the field from the footpath.

Refencing and desilting

Coopers field is now refenced and the cattle were moved into this field at the weekend. The contractors are now working on refencing the lower field where the woodland footpath emerges beside the Kyd brook. After this, Soldiers field will then be refenced. Both of these fields will be grazed with sheep once they’re livestock proof.

Desilting of the pond will commence in earnest this week. The silt from the pond will be spread across the field and left to dry out. Large bales have been placed in the field to prevent the silt running back into the pond. This job will create a lot of mess as the excavator tracks in and out of the field but this will all be levelled off when work is complete and vegetation will soon grow through in the spring.

Draining Flushers Pond and clearing fencelines

Work started on Tong Farm on Monday, 5 January with the removal of the old outflow system at Flusher’s pond. The two inlets have also been diverted to bypass the pond to allow it to drain sufficiently so that the silt can be dredged out towards the end of January.

As one of the inlets to Flusher’s pond comes from road run-off and through back gardens, the defunct filtration pond will be re-dug and planted with common reed to reduce the number of pollutants running into the pond from this source. High levels of nutrients and pollutants is evidenced by the blanket of duckweed that covers the pond each year. Removing the build-up of silt from the pond will also contribute to bringing nutrient levels down to create a much healthier, biodiverse pond in the long-term.

The old fences from Coopers field have been removed and the new fencelines are currently being installed. The fencing stakes are made from sweet chestnut, grown locally in North Kent. As well as being locally sourced they are much more robust and longer lasting than softwood posts.

Project Start

We'll be starting work on the Tong Farm project on Monday January 5 2026.

We'll put regular project updates on this blog and we aim to continue the blog beyond the work, so you can see the difference this project has made.
