23rd May 2021 – Moses Gate Country Park, Reedbed Management
(Text and photos updated 31st May 2021)
Reedbeds are a disappearing habitat in the UK, there are only 900 sites around the country and only around 50 are greater than 20 hectares. Many reedbeds have been lost to agriculture either through drainage or pollution, and climate change is now posing a threat to coastal sites as sea levels rise. But all is not lost, there has been a resurgence of interest in reedbeds in recent years as sources of biofuel, water treatment, and as an alternative source of compost.
BCV has been planting reedbeds since its early years, and for us it’s about wildlife. Reedbeds can support over 700 species from invertebrates to bittern, many of these species can be found nowhere else and are dependent on reedbeds for their survival. While urban environments don’t make ideal sites for large reedbeds small ones can still be very valuable to birds such as reed warbler and reed bunting.
23rd May – Today’s task was to continue the work started last year when we diverted a stream to re-wet an area to the north of the park, see the Hidden in the Reeds post for more info. Before we can plant any reeds we first need to create an area of open water, this we did by clearing the willow and creating a dam. The line of the dam was marked out by stakes and tree trunks, other trunks were cut into logs and driven down into the mud to create a palisade, gaps were filled in with mud. Once the dam was built we dug a channel to redirect the pooled water to another area. It was a bit of a learning experience and we were making it up as we went along but it turned out to be pretty effective. Additional dams will be needed to further manage water levels, then we can start planting. More info on creating phragmites reedbeds can be found in the download below (click the link to view or button to download), photos of today’s work can be found below that. Today’s task was funded by Bolton Council’s Climate Change Fund.
30th May – A week later we returned to the reedbed. The dam was still working, although the overall water levels has dropped a bit it was still retaining water as planned. The next step was to establish the reedbed itself. After moving some of the previous week’s brash out of the way we tried 2 techniques of reedbed creation. The first was to dig up some of the reed’s rhizomes from another area and plant them in the soft mud behind the dam. This is usually the most successful way of creating a new reedbed. The second technique was to use cuttings which we gathered from an established reedbed and push them into the mud. Although a bit early in the year for trying this it was worth a try, if the weather stays warm it has a good chance of working. More info on reedbed creation can be found in the download further down the page.
So now we wait to see what happens. Well done to everyone involved. The day’s photos have been added to the gallery below.
In another area of Moses Gate another team was working with Banana Enterprises on a different project, more about this will appear in a separate post shortly.
