VolunteerRewildingLondonRestore river banks through riparian rewildingLet native plants heal your river corridor Riparian buffers slow floods, filter runoff, and give kingfishers and otters room to return. Catchment trusts across Britain pair landowners with volunteers to fence off banks and plant willow, alder, and wildflowers. What you can do - Find your local Rivers Trust project and sign up for planting days - Adopt a short stretch: remove invasive species, stake saplings, and photograph wildlife returning - Invite neighbours to a walk-and-talk along a restored reach How it works Trust officers match volunteers with farmers and councils. Teams work in wellies for a morning: mulch, plant, and label plots so future stewards know what to protect. Why it matters Healthy river edges cool cities downstream, reduce erosion, and turn muddy banks into corridors children can explore safely.riverriparianrestoration +1

The guide suggests 1 to 1.5 hours for children and 2 to 3 hours for teens and adults. Why it matters River litter is visible, local, and fixable in an afternoon. When neighbours measure what they remove, they see how small habits upstream add up, and new groups keep returning each season.rivercleanupvolunteer +2

EventCommunityFrankfurtTake part in spring cleanups on Main, Mosel and in FrankfurtTake part in spring cleanups on Main, Mosel and in Frankfurt Before the big September action, the network runs an early-season window on tributaries in Frankfurt. In 2026, Main, Mosel, and Kinzig cleanups are scheduled 13 to 22 March, with a Dreck-weg-Tag in Düsseldorf on 21 March. Use the river programme sites to find open groups or register your own. What you can do - Browse spring listings on MainCleanUp, MoselCleanUp, and KinzigCleanUp - Follow the CleanUp-Leitfaden for waste-office coordination and safe bank access - Join municipal formats such as Rüsselsheim's CleanUp Walks that combine Main shore work with neighbourhood Dreck-weg days - Register an open group if your stretch has no public listing yet How it works Each river hub lists upcoming public cleanups with registration forms. Organisers confirm meeting points closer to the date. Spring events prime the shore for summer use and feed into the September network day. Why it matters Tackling litter after winter floods and before peak river recreation keeps plastic and glass from drifting downstream. Spring rounds spread the work across more weekends so smaller towns can join without running a second large event alone.riverspringcleanup +2
CommunityDüsseldorfCollect cigarette butts during KippenwocheCollect cigarette butts during Kippenwoche R(h)ein-Kippen runs each 1 to 8 May as a week-long butt-collection action ahead of the September river day. Cigarette filters leach toxins into water; counting and removing them makes the problem visible without guilt-only messaging. What you can do - Join an open Kippenwoche group via RhineCleanUp MACH MIT or MainCleanUp - Organise a small team: use screw-top jars or cartons, wear disposable gloves, and tally what you find - Request butt bins, grabbers, and gloves from the programme where offered; some cities also set up collection columns to show scale - Read the R(h)ein-Kippen overview for background and dates How it works The action lasts one week each spring. You can collect solo or register a public group. RhineCleanUp reports community totals (for example over 250,000 butts in Düsseldorf in past years) to sharpen prevention conversations with councils and venues. Why it matters Butts are among the most common items on European riverbanks. A focused week trains the eye, keeps filters out of storm drains, and builds habits that carry into the larger shoreline cleanups in September.cigarette buttspreventionriver +2
