Volunteer Sessions in April

April had our volunteer team venture to Beckenham Place Park to clear the river channel of large fallen tree branches, obstructions and litter. All removed branches were cut down and used to create habitat piles along the higher banks.

After a successful grant award from Groundworks, Rivers & People joined forces with the Friends of Chinbrook Meadows for a celebration event for how diverse the park is. Read more about the event at https://chinbrookmeadows.wordpress.com/. Twenty different species of aquatic species were found during the day of pond dipping, including smooth newts and common frogs.

Volunteer Sessions in March

March gave our volunteer team some kinder weather, which was particularly welcomed as we spent 3 weeks in Ladywell Fields (North Field) widening the secondary channel around the bridges. Since the works have been completed at the entrance to the secondary channel you can now see the channel filled with water everyday through the field. As this waterflow moves through the channel it naturally erodes areas of the banks where it is moving fastest and drops silt in the slower areas. This is a wonderful natural process to watch happening through the middle of the park. Our volunteers have managed to rework the meander by the middle bridge to reduce any erosion where the bridge is connected to the path, and to open up the inflow channel to the backwater located here.

Further south into the borough our volunteer team have been removing litter and being vigilant for invasive non-native plant species in the Manor Park section of the River Quaggy.

Volunteer Sessions in February

February threw us some colder and wetter weather, which meant on some sessions we focused mainly on bank side work rather than being in the river channel itself. When the weather gave us some respite we spent a few sessions in Ladywell Fields litter-picking in the channel, we often find smaller items within the channel like cans, plastic bags etc. Sometimes we find much larger items, like the lime bike and building sign above. The wonderful volunteers managed to get these out of the channel then Glendale’s park cleansing team were able to take them away from the site.

Another of our projects in February was working on the main dipping pond and it’s channel at Chinbrook Meadows. Over time silt and leaf litter had filled up the inflow from the River Quaggy, so our team cleared a nice secondary channel that feeds into the pond under the boardwalk. Keeping water in this pond will allow for a wide variety of invertebrates (and a few vertebrates) to thrive in the standing water habitat, rather than the moving water from the River Quaggy.

Rivers & People April-June Programme

Spring and early summer is a great time to be in the river, and track how the banks change and flower as the seasons change. Why not join our Tuesday volunteer sessions? The volunteer session programme has now been released for April to June 2023. Check out the programme HERE. If you would like to get involved in volunteering on Lewisham’s rivers please read through the the River Volunteering web page, and if you have any questions or queries please get in touch with Emily.

Volunteer Sessions in January

We started 2023 with a sunny session at Cornmill Gardens, where we cut back any branches overhanging the river and clearing all the twigs that had collected on the bank from the recent rains. We don’t remove any of the deadwood from the site, but rather move it further up the bank to create habitat piles that won’t get washed downstream.

Next up we visited the River Quaggy, at Chinbrook Meadows, where we de-silted the secondary channel that feeds into the pond and wetland area. Also that afternoon, our diligent volunteers scraped the leaf litter from the boardwalks to make them easier and safer to walk on.

After a wet December where we couldn’t get easy access to the Ladywell Field backwater channel, we returned to finish the de-silting here. The heavy digging work certainly lent itself to an extra biscuit with our tea afterwards!

Our last session of the month was in the north of the borough at Brookmill Park, where we completed our bank work to allow any pedestrians a sight line down onto the river. As an added bonus we came across a common frog, Rana temporaria, and two common toads, Bufo bufo, which is one of Lewisham’s priority action species.

An excerpt from Lewisham Council’s Biodiversity Action Plan ‘A Natural Renaissance for Lewisham (2021-2026)’

Amphibian species populations are declining at an alarming rate globally and despite its
name and that it is found throughout Britain the Common Toad is not so common anymore. A study in 2016 found a significant decline (68%) of the species in the UK since 1980s with an even steeper decline in South East England (www.froglife.org)

Common Toads breed in ponds but spend most of their lives on land away from water, walking (and not hopping) around at night looking for slugs, snails, spiders and other invertebrates. They spend winter buried under log piles, stones, leaf litter or compost heaps. Adult toads usually migrate back to their birth pond to breed which is becoming
more and more difficult with fences and busy roads blocking their way in urban areas. The disappearance of ponds in gardens and open spaces and two amphibian diseases (Ranavirus and Chytridiomycosis) pose further threats to toads. The Common Toad is protected from trade and sale under the Wildlife and Countryside Act 1981 (as amended) and was identified as a priority species in the UK Biodiversity Action Plan in 2007.

Volunteer Sessions in December

As usual, the Rivers & People volunteers have been busy keeping the rivers in Lewisham in good shape! A day of bramble bashing at the backwater in Ladywell Fields South took the brash line back by about 2 meters, which is great not only for regaining the visibility of the river but also protects the meadow area from any encroaching bramble! All the cut bramble was bundled and used in a brash pile within the nearby woodland.

Further upstream in the River Ravensbourne volunteer Donna cleared all the litter and fallen twigs from the Turning Tree sculpture in the channel, look at transformation below!

A river wade and litter pick also took place in the Manor House Gardens stretch of the River Quaggy, although chilly it was a fantastic day to be in the river!

#PlasticBlitz

Last month, the Rivers & People volunteers took part in The Thames and Tributaries ‘Plasticblitz’ week. This week of events was organised by Thames21, the Environment Agency and Rotary in the Valley (through their international End Plastic Soup campaign) to collate details on the amount and differing types of plastic pollution groups find across The Thames and it’s tributaries.

The Rivers & People group held a session at Brookmill Park where we cleared 6 bags of rubbish from the Ravensbourne River and it’s banks. A wide variety of litter was collected from plastic bottles to curtains. Our team collected 6 full bags of rubbish over a few hours and covered a stretch of river over 250 metres.

All of the data collected will feed into the EU-wide ‘Preventing Plastic Pollution’ Project.

Find out the overall results of the #PlasticBlitz HERE.

Hello, introducing Emily!

Hello everyone!
This is just a short blog post introducing myself as the new nature conservation officer for Glendale Lewisham. With my appointment I can also share the good news that we will be restarting the Tuesday Rivers & People sessions from Tuesday 20th September at Brookmill Park. Booking for this session is essential- especially as we will need to bring you waders that fit!

Over the next few weeks I will be updating the webpages on this website, including adding the programme of sessions for the next quarter, and an updated volunteer form. If you have not volunteered with Rivers & People before and would like to join in the coming weeks, please do not hesitate to email me at Emily.Millhouse@glendale-services.co.uk and I will email you a volunteer form.

Hope to see you at a session soon!
