Making space for nature

A major part of this project is habitat improvements within the Pocklington Canal Site of Special Scientific Interest (SSSI). Dredging is currently underway to create open water habitats in areas that have become dominated by reed sweet-grass.

As the Pocklington Canal SSSI lies within a non-navigable section of the canal, there has been limited work carried out to the canal along the length between Canal Head and Melbourne. In the 1980s, the canal was designated for its aquatic plants and invertebrate life (particularly dragonflies) which affords protection of the habitats from damage or neglect.

However, left to its own devices the canal has become more and more vegetated, through the process of succession. Reed sweet-grass has taken over sections of the canal which, if left unmanaged would see the canal dry out. In addition, this dense growth limits the light from getting to the bottom of the canal, which is essential for the survival of aquatic plants. Sadly parts of the SSSI are in poor condition, and needed improving.

As part of the application phase of this project, the Canal & River Trust’s Ecologist and Natural England’s Senior Land Advisor walked the length of the towpath to select the areas that would benefit the most from dredging. In late November 2017, specialist dredging contractors began work on the first of two sections.

Top Lock (Canal Head) to Silburn Lock was the first section to be done, which saw a channel 4m across and 1.25m deep dredged to create a open water along the centre of the canal. In spring, when the surrounding ‘emergent’ vegetation comes back, we will see a clear channel surrounded by taller plants offering protection.

Land & Water are currently working between Church Bridge (Melbourne) and Walbut Lock. Day one was a rather snowy day across the country – but work didn’t stop! BBC Look North journalist Crispin came along to record the work in action for the evening news.

The work will continue for another month, with the team expecting to be done by the New Year. It will take a while for the fruits of this labour to become apparent, but we are monitoring the plant life within the canal through annual summer surveys will a local specialist naturalist in aquatic plants.

Pocklington Canal

Pocklington Canal – a gem in the landscape has been supported by a grant from the Heritage Lottery Fund. Thanks to National Lottery players, we will be restoring Church Bridge and Swing Bridge No 7, restoring the special wildlife habitats along the canal and running a series of exciting community events and activities to showcase the rich heritage of this idyllic rural East Yorkshire canal.
