Thank you for booking a place at our event in front of the Hurlingham Club at&nbsp;Broomhouse Dock. We will send out more details closer to the event date.

Come along and join Thames21 as a river citizen scientist on the River Thames. We will be collecting the litter we find and categorising it into sewage derived litter, plastic items, and other litter. This will help us to determine the quantity of litter turning up along the river side and to investigate which litter category is the biggest problem. We look forward to welcoming you to our event which will cover everything you need to know to carry out a litter survey or clean up with Thames21 Citizen Science Volunteer for Thames River Watch. Both new and existing Thames21 volunteers are encouraged to attend and investigate plastic pollution on the Tidal Thames. This event is suitable to anyone (over the age of 10 with an adult) who has an interest in plastic pollution or if you want to help monitor and improve the Thames river. This is an event designed for the community to engage the local public with the river and not for corporates. If you are interested in a bespoke corporate volunteer day.

Thank you for registering your place at Thames Road Wetland. We will be in touch with further details the week before the event. If after registering, you are unable to attend, please cancel your place so it can go to people on the waiting list. Many thanks :)

Despite its urban surroundings, Thames Road Wetland which sits within the Green Belt, is part of a Site of Metropolitan Importance for Nature Conservation, making it one of the best sites for wildlife in London. It is home to national, London and Bexley rarities including stately MarshSow-thistles, tiny Brookweed, Water Voles and Harvest Mice along with a wide range of invertebrates and birds such as Water Rail, Cetti's and Reed Warblers. Wetlands like this are crucial for biodiversity and play an important role in purifying water, reducing flood risk, and storing carbon. Like other sites in urbanised areas, it lacks the full range of species that would once have helped maintain a balance of wildlife, such as a variety of large herbivores and carnivores. That's where the Thames Road Wetlands group comes in... Whilst a small group, led by volunteer site manager Chris Rose works at the site most weeks, we are now holding larger public volunteer sessions on the 2nd Friday (as much as is possible) of each autumn and winter month and less frequently in spring and summer, with all tools, waders and kit provided. Autumn and winter activities include cutting and removing Reed from shallow areas to maintain open water for birds and dragonflies, sustain a greater variety of plant species and reduce drying out. Also pollarding Sallows (cutting back selected trees and chopping up and stacking the brash), silt removal, occasional path work and some litter picking duties. There is less to do in spring and summer. Reed re-growth needs cutting and removal. Reptile basking sites have to be kept open. Shrub extension growth encroaching on paths needs trimming back. Some selective 'weeding' is carried out around rarer species. Tasks generally require greaterknowledge and/or closer supervision so are easier to manage with fewer and more regular volunte ers. We also need to avoid disturbing breeding birds. We therefore have fewer staffed events at this time of year. Besides supporting the site's wildlife, helping out is a rewarding way to connect with nature and benefit your local community. The August event will include some or all of the following tasks:<ul><li>Raking out the next cut of Reed at the west end.</li><li>Digging out Reed rootmat and silt from north-west corner pool.</li><li>Using pole pruner to cut out Reed/Reedmace stems from main ditch and/or River Wansunt</li><li>Complete the emptying the of road run-off trap.</li></ul> You will need work clothes, adequate sun/rain shower protection and any food and drink required. There are toilet facilities nearby at the council depot which also has a canteen. There are some convenience stores about 10 mins away. Tea, coffee and biscuits are provided. The events start at 10.30am, but please arrive at 10am to get kitted up and briefed at the meeting point, which is by the steps near Thames Road on By-way 105 (what3words location: dome.silly.above) near the bridge where the road crosses the River Cray. Please contact Sam at Samantha.Dhedhi@thames21.org.uk if you have any further questions. Please book your place so we can ensure we have kit for you. Finish time is around 2pm, but feel free to go whenever you need to. Chris Rose. Volunteer Site Manager.

Thames Road Wetland: Help Manage An Important Wetland

Thames Road Wetland

Join the Ching Action Group for a one‑day, in‑person MoRPh (Modular River Physical) training session combining indoor learning with a guided field exercise along the River Ching, just a short walk from the venue. MoRPh surveys are a method for documenting the physical habitat characteristics of rivers — including channel shape, vegetation, flow types, and bank features. By collecting this information, volunteers can help build a detailed picture of river condition, identify pressures and opportunities for restoration, and track how the river changes over time. This training equips participants with the skills to carry out MoRPh surveys confidently and contribute valuable data to support evidence‑based river management. It also strengthens local stewardship by deepening understanding of how healthy river systems function and how communities can play an active role in their protection. To bring: Lunch, water, flask of tea or coffee, notepad and pen, fully charged smart mobile device, outdoor wear appropriate for the weather.&nbsp;

Join us to turn Oxleas Woods into a flood-fighting, biodiversity-boosting powerhouse! This winter, join us for 15 fun and hands-on volunteer events as we transform Oxleas Woods into a thriving wet woodland. Together, we’ll help slow the flow of floodwater, protect downstream communities, and create a vibrant habitat for wildlife. Last year, we installed 16 leaky dams along the River Wogebourne, which flows through the heart of the woodland. This year, we are extending this work to the smaller tributaries of the Wogebourne, helping to retain even more water within the woodland. We are also creating dead hedges in eroded areas to protect and encourage the recovery of the woodland understory.

Join us to bring the River Beck back to life! A total of 7 fun and interactive volunteer events will be held throughout the winter season to restore the River Beck to its former glory. The River Beck is a valued local blue space that runs through High Broom and Harvington Woods, but heavy public use has led to widespread bank erosion and increased sediment entering the river. Our mission is to use nature-based solutions upstream to reduce erosion, improve wildlife habitat, protect riverside paths, and help prevent costly downstream sediment build-up. Activities include installing dead hedging, creating natural berms at the toe of the river bank, installing deflectors in the channel to improve the health of the river and removing invasive vegetation.

Help protect the River Thames by measuring the impact of wet wipes deposited on its shores! Join Thames21 to gather crucial data on the wet wipes settling in the Thames by getting down and dirty to count them! Until the Thames Tideway Tunnel was connected up earlier this year, rainfall in central London often caused the sewers to overflow, sending hundreds of thousands of wet wipes into the river where they accumulated on the riverbed. The Big Wet Wipe Count has allowed us to record the scale of the problem, and we are looking for volunteers to continue these surveys, which will now help to assess the impact the tunnel. To assess the scale of the problem and the impact of the tunnel, we are looking for volunteers to survey the wet wipes on the foreshore and record the final number. Children under 16 need to be supervised by an adult. This event is not suitable for children under 10 years old.&nbsp; This is an event designed for the community to engage the local public with the river and not for corporates.

Join us to bring the Dollis Brook back to life! A total of 10 fun and interactive volunteer events will be held throughout the winter season to restore the Dollis Brook to its former glory. Historic toe-boarding has left Dollis Brook with a uniform channel shape, limiting the number of suitable habitats for wildlife. Our mission is to install woody debris in the channel to create a more diverse flow pattern, improving habitat for fish, invertebrates and other species. This will also help the brook develop a more natural form over time and support the recovery of the riverbanks from the artificial shape imposed upon it.
