Land Yeo and River Kenn floodplain
The floodplains of the Land Yeo and River Kenn offer opportunities to reconnect the rivers to their floodplains and create wetland habitat, which would be hugely beneficial for nature, although the deeply incised nature of parts of the rivers may make this challenging and impacts on flooding elsewhere must be considered. The rewetting at Watercress Farm offers an ambitious example of such 'rewetting' could be achieved.
Establishment and best management of riparian vegetation and buffers along the riverbanks where they are bare would also benefit wildlife in and out of the rivers. The River Kenn and its floodplain in particular is an important foraging corridor for greater horseshoe bats from the Brockley maternity roost and other wildlife.
There could also be an opportunity to build on the ‘rewilding’ underway at Watercress farm to create a larger area of nature-rich habitat and nature-friendly farming.
Easing or removing the barriers to fish passage along the Land Yeo would also open up the river to fish including the critically endangered European eel. Surveys from BART have also identified issues related to poaching and trampling by livestock on the Land Yeo, which are negatively impacting river ecology, and should be addressed.
Priorities for nature recovery
Delivering the priorities for nature recovery is particularly important in the mapped Focus Areas for Nature Recovery. ‘Landscape recovery’ measures, which will have the biggest impact on nature recovery, are particularly relevant in these Focus Areas.
| Measures | Most relevant to | Land type | Indicative level of land-use impact for nature |
| Remove Himalayan Balsam from riverbanks, starting at the top of rivers and working downstream* | Farmers and landowners Communities |

There is a greater amount of land where extensive grazing creates diverse, dynamic and shifting habitat mosaic, including successional habitats and scrub.
| Measures | Most relevant to | Land type | Indicative level of land-use impact for nature |
| On areas that are currently biodiversity-poor, use a mix of free-roaming herbivores with different grazing habits to create a dynamic and shifting mosaic of habitats. Ideally, this should be done in a large enough area for natural processes to create habitat variety. | Farmers and landowners | Countryside | Landscape recovery |
| Reduce the intensity of existing cattle grazing to improve biodiversity and create dynamic grassland mosaics; this could include introducing more hardy, native breeds of cattle, and introducing ponies alongside them. | Farmers and landowners | Countryside | Landscape recovery |
| Manage areas of scrub that are in good condition to avoid them losing their scrub or thicket-like characteristics by, for example, coppicing on a suitable rotation and using appropriate grazing regimes. | Farmers and landowners | Countryside | Landscape recovery |
| Measures | Most relevant to | Land type | Indicative level of land-use impact for nature |
| Manage existing wetland habitats to maintain/improve their value to wildlife. Management techniques will depend on the type of wetland habitat present | Farmers and landowners | Countryside | Landscape recovery |
More rivers and streams have natural courses and profiles, enable free passage of fish, and have more diverse in-river habitat, including spawning habitat in headwater streams.
| Measures | Most relevant to | Land type | Indicative level of land-use impact for nature |
| Re-naturalisation of rivers to their original form or reprofiling of the river to create a more ‘natural’ profile. This could include restoring meanders, removing or setting back flood banks, and/or reconnecting old side channels. | Farmers and landowners | River | Landscape recovery |
| Introduce habitat features such as berms and flow deflectors in rivers to create more habitat diversity. This is particularly useful in river channels that are relatively uniform or highly managed | Farmers and landowners | River | N/A |
| Install natural structures such as leaky dams and let fallen trees in rivers remain in-situ (where appropriate and where the flood risk has been properly assessed) | Farmers and landowners | River | N/A |
| Restore headwater streams to enhance spawning habitat such as river gravels for salmonids, and instream water weeds and substrates for coarse fish egg laying | Farmers and landowners | River | N/A |
| Remove barriers to fish passage, including weirs and culverts, where this is possible, and the retrofitting of structures to include fish passes and mammal ledges where removal is not possible | Local government Farmers and landowners |

The role of rivers and streams as ecological corridors through the landscape is enhanced, with diverse riparian habitat that benefits a range of species, stabilises banks, captures nutrients, regulates water temperature and provides vital shade during warm weather.
| Measures | Most relevant to | Land type | Indicative level of land-use impact for nature |
| Create and manage riparian buffer strips (of 5-50m, depending on the size of the watercourse, with larger buffers providing greater benefits) of vegetation including trees alongside rivers and streams. This will improve river ecology, create natural corridors, reduce pollution reaching rivers, and provide natural flood management | Farmers and landowners | River | Landscape recovery |
| Manage riparian vegetation to ensure a mosaic of light levels along the river, aiming for a 60/40 ratio of light to shade, and a dense understory to enhance the slow of runoff and increase infiltration rates | Farmers and landowners | River | Landscape recovery |
| Coppice bankside trees to increase their longevity and health | Farmers and landowners | River | Environmental stewardship |
| Active management of poaching by cattle along rivers, which would also help to reduce nutrient load into rivers. This may be achieved through the installation of fencing where it is appropriate and compatible with flood risk maintenance activities. | Farmers and landowners | River | Sustainable farming |
There are more waterbodies that are in good ecological status and support thriving populations of fish and other freshwater wildlife.
| Measures | Most relevant to | Land type | Indicative level of land-use impact for nature |
| Create a sediment pond or trap to provide an area where muddy run-off from fields or tracks is allowed to pond, so that sediment will settle out before entering watercourses | Farmers and landowners | Countryside | Sustainable farming |
| Reduce run-off of pollutants from farmland through the use of best practice in applying fertiliser, manure and slurry | Farmers and landowners | Countryside | Sustainable farming |
| Establish a buffer strip (which can contain long grasses, trees, and shrubs) of 4-12m on field boundaries or runoff channels. This can reduce nutrient and pollutant runoff into watercourses and provide habitat for wildlife | Farmers and landowners | Countryside | Sustainable farming |
| Improve management of manure and slurry to reduce pollution (e.g. roofing manure storage or manure storage pads) | Farmers and landowners | Countryside | Sustainable farming |

More rivers are reconnected to their floodplains and floodplain wetlands are created to allow natural erosion and silt deposition within the floodplain, especially where this would provide benefits to flood management.
| Measures | Most relevant to | Land type | Indicative level of land-use impact for nature |
| Reconnection of rivers to their floodplain, allowing floodwater to spill naturally onto adjacent land, and restoration of wetland habitat within the floodplain | Farmers and landowners | Countryside | Landscape recovery |
| Create or improve management of floodplain grazing marsh or floodplain meadows, including permitting seasonal flooding | Farmers and landowners | Countryside | Landscape recovery |
Nature-based solutions are used to slow the flow of water and increase water storage in the landscape, thereby reducing the risk of flooding, and mitigating the impacts of drought and water scarcity
| Measures | Most relevant to | Land type | Indicative level of land-use impact for nature |
| Cross-slope planting of trees and hedgerows to intercept flows of water, providing natural flood management and capturing pollutant run-off | Farmers and landowners | Countryside | Environmental stewardship |
| Create in-field wetland scrapes (shallow ponds that hold rain or flood water seasonally but stay damp for most of the year) and swales (shallow, linear, vegetated drainage features) to store and slow the flow of water, providing natural flood management | Farmers and landowners | Countryside | Environmental stewardship |
| Create offline and/or online ponds in the floodplain. Offline ponds are not connected to the watercourse, and can capture overland runoff. Online ponds are connected to the watercourse through a stream channel, storing floodwater temporarily and releasing it into the watercourse in a controlled manner. | Farmers and landowners | Countryside | Environmental stewardship |
