Project summary

Edit project overview to modify the project summary.


Beginning in 2022, the Washwalk Wetland project focuses on rewetting a 906m stretch of floodplain along the River Gara. The aim is to enhance the local environment by slowing water flow and reconnecting the channelised river to its floodplain through the felling of trees across and into the channel.

Monitoring surveys and results

Edit project overview to modify the Monitoring survey and results.


Monitoring has been primarily based on personal observations. Family and friends involved in the project have reported positive changes, such as increased water variability and enhanced vegetation growth along the banks. The presence of indicator bird species is used to track the project's success, with hopes of attracting more wader species. So far, kingfishers, mallards, herons, and little egrets have been observed.

Lessons learnt

Edit project overview to modify the lessons learnt.


This is an ongoing project still in its early stages. One key lesson learned is the importance of patience and continual observation. While initial signs of success, such as increased vegetation and bird sightings, are encouraging, long-term outcomes will require sustained monitoring and adaptive management. Engaging family and friends has also proven valuable, offering diverse perspectives and shared commitment to the project’s goals.
