Unit 30

This is made up of the two ‘Long Pits’ on this area that had been previously extracted for aggregate in the 1940s. As a result of these past activities Unit 30 displays two waterbodies surrounded by shingle habitat and displays wet shingle margins and associated bird, invertebrate and plant interest.

Managing the wetland margins for Baldellia is key and recent work has cleared baclk willow scrub successfully to expose the muddy margins where the plant is present.  Cutting has been quite extensive. Just be aware that reed or reedmace colonisation may be hard to control.  If so might be better to go for willow coppicing in the absence of grazing or browsing so that emergent plants are shaded out at intervals.

Reedbed – maintain as it is.  Full of warblers, and no doubt good for cuckoo.

Comment: This unit is mainly occupied by a long narrow water body created after gravel extraction along the shingle ridge line in the 1940s. The water body is of nature conservation value for the swamp vegetation and associated marshy habitats, as well as being of interest from a geomorphological perspective. The swamp vegetation feature is regarded as being in unfavourable condition because there is very high cover of scrub, mainly willow carr, surrounding and occupying much of the system. This is resulting in high levels of shading which in turn is causing loss of swamp and aquatic vegetation, much reduced plant diversity, and poor habitat quality for wetland invertebrates. A strategy is now in place to address the scrub problem and funding is in place to instigate appropriate management. This will ensure recovery of marginal swamp vegetation and promote restoration of the adjoining marshy grassland habitat.
