📢It's #WorldRiversDay on 24 September and we're celebrating by giving away a FREE digital downloadable copy of our Freshwater Biology and Ecology Handbook! Grab your copy here: fba.org.uk/shop/p/freshwa… #FreshwaterScience #FreshwaterBiology #FreshwaterEcology #KnowledgeExchange

📢 Attention all artists, photographers and writers! Our rivers are a source of inspiration and we want to showcase your work on our pages. Send or Tweet us your best images, artwork, videos, or writing that celebrate our waterways! 💦 #wildlife #rivers #photography #writing

**We must give #floodplain land back to our rivers**. Farming floodplains, like this one on the Great Ouse, is awful for river water quality, carbon & species & precarious for the farmer. We urgently need to #farmback from our rivers @greatousert

Great opportunity to do some amazing work with an amazing organisation! Help save our rivers! 👍

Contrast the dry Upper Derwent with the flowing Calder. Why? The Derwent was moved to the side of the valley and sits perched above its floodplain, the Calder flows freely across the valley floor! Put our rivers back where they belong and they won't stop flowing in dry spells...

Walk along the upper Wharfe today, great to see some of our rivers still functioning properly, great pool/riffles sequences 😍 #GoodEcologicalStatus

UK rivers contain a toxic #chemicalcocktail that's speeding up nature-loss ⚠️ Support the @theriverstrust movement in calling for an end to these harmful chemicals by signing an open letter to government🛑👇 📩theriverstrust.org/chemical-cockt…

@NT_TheNorth One for your eagle eye @frogsatuea

@Rach_Archaeo Love that view, heading there next week!

Industrial archaeology across the River Nidd. Knaresborough Viaduct.

@carlsayerUCL @NorfolkWT @norfolkponds Amazing work Julia and co - Crassula heros!

After 1.5 yrs of repeated hand picking & digging out of invasive Crassula helmsii from the ponds at Thompson Common, Norfolk, this awful invasive plant is now virtually eliminated. It would have destroyed the reserve. Well done Julia Mumford of @NorfolkWT @norfolkponds & vols!!!

@carlsayerUCL @RiverGlaven v good nutrient buffer too!

Riparian forest & river recovery. 10 years of low grazing following embankment removal on a section of @RiverGlaven has allowed for substantial riparian Alder development. The little trees are growing fast. Huge benefits come from riverside trees living & fallen

Give nature some space 👌

Last year I decided to sew some wildflower mix over a scrubby part of our lawn, helped along with some hand harvested yellow rattle seed from high Norfolk. Less than 10 months on and this little patch is looking so much more diverse. #wildflowerhour

📢 How can you help our troubled rivers? We’re looking for volunteers to support #citizenscience water quality testing in the Wensum headwaters 💦🧪 A robust evidence base is crucial to fully understand the complex issues and drive action. bit.ly/3pr2T2f Register👇

Great project, glad to have played a part in making this happen.

On a revisit last week, we were unable to drone due to nesting birds but the site was buzzing with activities. Mammals; Otter, water vole, hares & roe deer. Birds; Shelduck, moorhens, mallards, chiffchaffs, waterail & heron. A place for water purification but also for wildlife.

Vast mats of macroalgae at Blakeney Point, N. Norfolk. A symptom of eutrophication which reduces the ability of wading birds to feed. We urgently need to improve water quality at source in our rivers. A very sensitive habitat badly affected here

Time to get our strip mower up and running. 1st time through some pasture/winter wheat strips. Soil type at Ken Hill is sandy silt loams, second year with out any synthetic inputs. #wildkenhill #Wildfarmed

We will revisit this wetland at the end of the week to see how it has progressed over the last few years. It was created for @AnglianWater to remove nutrients from the sewage works, cleaning the water before it reaches the river.
