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.

Emily M 3 Rivers Clean Up, Lewisham Rivers, Volunteer

Dates for your Diary!

2023 dates for the 3RiversCleanUp is 17th June – 15th July

The 3RiversCleanUp is an annual, intensive series of volunteering events that aims to improve and maintain the Rivers Pool, Quaggy and Ravensbourne that flow through Lewisham, Greenwich and Bromley.  The events are organised by a unique partnership between the Environment Agency, environmental groups and local authorities.

The first 3RiversCleanUp took place in 2008 with the main aim to control the growth of Himalayan Balsam along the rivers. Himalayan Balsam is an invasive non-native plant that spreads quickly, clogging up river banks and reducing biodiversity. It shades and crowds native species and causes riverbank erosion, leading to an increase in the risk of flooding.

Volunteers are still needed to help maintain these valuable local spaces for people and wildlife.

Read more about the 3RiversCleanUp on the event’s website at https://3riverscleanup.co.uk/ and keep an eye out for more details!

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!

Volunteer Sessions in November

The Rivers & People volunteers have been all across the borough this month despite the very wet weather. The volunteer team have opened up one of ponds in Chinbrook Meadows, by cutting back some of the overhanging willows and removing the encroaching sedge and grasses. They also got into the River Quaggy to unblock the channel from a fallen tree, the bankside volunteers then used the bras cutting to create a habitat pile further into the woodland.

The team also visited Brookmill Park to do a quick kick sample for the Riverfly Monitoring Partnership. Although it is later in the year it was interesting to find a selection of freshwater invertebrates such as caddisfly larvae, leeches, freshwater hoglouse, mayfly nymphs. After our short sampling session the volunteers worked to clear a section of the overgrown bramble on the bank, so that any park visitors using the pathway can now see the River Ravensbourne. We only clear half the sections in winter to keep some coverage for birds to forage in whilst maintaining a view of the river.

As a pre-festive period treat, you should visit your local blue space and see the wildlife that’s about. Black headed gulls, kingfishers and grey wagtails are common sights in ponds and on the river around the borough. If you do spot anything please do share your sightings with @GlendaleLew as we’d love to know!

#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.

We also have a number of river related volunteering opportunities.  We are keen to get people involved in their local rivers and help us maintain them through bankside management and litter picks.  We tend to work in  4 parks; Brookmill Park, Chinbrook Meadows, Cornmill Gardens and Ladywell Fields.  If you would like to get involved, please visit the River Volunteering tab where you will find all the information you need.
