SUMMARY:CANCELLED DUE TO HOT WEATHER - River Litter Detectives - Queenhithe
DESCRIPTION:Book your place HERE! \nCome 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. \nWe 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. \nBoth new and existing Thames21 volunteers are encouraged to attend and investigate plastic pollution on the Tidal Thames. \nPlease note that access to this site is a little challenging\, requiring climbing a step-ladder\, and over a wall. If you would like any further information about this\, please contact samantha.dhedhi@thames21.org.uk. \nThis 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.

SUMMARY:London Rivers Week 2026: Introduction to MoRPh CSci training event [FULLY BOOKED]
DESCRIPTION:As part of London Rivers Week\, Cartographer are hosting a free\, open\, in-person ‘Introduction to MoRPh’ training. This one-day training course will teach you how to conduct a MoRPh survey so that you can assess and monitor the physical health of your river. \n\n\nWhy MoRPh? The MoRPh survey is conducted at short river lengths and records physical habitat\, vegetation and human impacts. Surveys are entered into the MoRPh Citizen Science database which produces a series of condition indicators about the health of the river. This introductory video provides further information about the MoRPh survey. \nWhat does the training involve? This course will teach you how to conduct a MoRPh survey and how to enter and view surveys in the database. This one-day training includes a morning of classroom teaching\, followed by riverside field training in the afternoon. We will be visiting a newly-restored section of the River Crane to see how MoRPh can be used to monitor the impacts of restoration. The course will qualify you to become a MoRPh CSci surveyor. \nNumbers are limited and booking is essential! \nRegister here.\nPlease send any questions to: training@cartographer.io

SUMMARY:Freshwater Watch training: Thames (Wallingford to Caversham)
DESCRIPTION:Are you concerned about the health of the Thames and other local streams and brooks? \nDo you have half an hour a month to spare? \nDo you want to be part of a research project and become a “citizen scientist”? \nIf the answer to the above questions is yes\, then we invite you to become one of our new Thames Water Watchers! \nApologies\, this event is now fully booked. You can sign up to the waiting list here: https://book.plinth.org.uk/e/CYp5dxH6Ul9914WVpG04 \nIf you want to be added to our local mailing list to hear about our next opportunity\, please email claire.robertson@thames21.org.uk \nWater watchers test for pollution in their local river or stream regularly\, usually once a month. The data collected helps to protect rivers. All of the data will be shared with the local group\, catchment partnership\, the Environment Agency\, Thames Water\, local councils and the media\, and used to highlight issues in our local rivers and push for improvements and change. \nFor this training event\, we are looking for volunteers who are interested in monitoring the Thames from Wallingford to Caversham. \nA map of the potential sample sites can be viewed here: https://tinyurl.com/ae2x7h5s  \nThe training event will cover: \n\nAn introduction to river health and river pollution\nIntroduction to citizen science for rivers\nHow to take a freshwater watch sample for phosphates\, nitrates\, and monitor visual pollution (field demonstration)\nCollecting and uploading data to the freshwater watch website\nSelecting a sample site\nBeing a guardian and advocate for your local river: first steps\n\nThis training event is run by Thames21 on behalf of the South Chilterns Catchment Partnership. This project was made possible with support from the Mend the Gap programme. \n \nThe South Chilterns Catchment Partnership is a group of organisations and individuals who are working together for a healthy\, thriving water environment for people and wildlife. Our vision is a network of healthy streams\, rivers and other freshwater habitats\, with flourishing nature and clean\, plentiful water\, particularly in our globally rare chalk streams. People value and enjoy the freshwater environment and use it sustainably\, and nature and communities are resilient to flooding and the effects of climate change.  More information here: https://southchilternscatchmentpartnership.org/
