正文(英文) | Volunteers clear floating pennywort from 10km of the River CamVolunteers have helped the Environment Agency eliminate floating pennywort along a stretch of the River Cam in Cambridgeshire. Thanks to the determination of volunteers the 10 kilometres stretch between Byrons Pool and Jesus Green lock is now clear of floating pennywort. The invasive non-native aquatic plant had formed thick mats along the river and was growing at a rate of 20 centimetre a day. This meant back channels were lost, navigation for boaters and canoers was difficult and repercussions for wildlife and plants was more likely. The Environment Agency and the Cam Conservators undertook the initial surveys and worked together to remove large masses of the invasive plant with weed boats. Mike Foley, a retired volunteer at Cam Valley Forum, continued the work and has spent years tackling the invasion on the River Cam. Mike has worked relentlessly to clear the invasive plant. Over the last year he worked extra hard to ensure the momentum carried on when meeting in groups has been difficult to coordinate. Anne Miller, a volunteer who worked closely with Mike, helped raise funds so they were able to prune 3 kilometres of overhanging branches. This allowed them to remove pennywort which was trapped, this was critical in the elimination of the invasive plant. Anne Miller, a volunteer from the Cam Valley Forum, said:

Tom Larnach, river manager at Cam Conservators, said:
Pennywort can change the availability of oxygen in the water which threatens fish and invertebrates. It can also choke drainage systems and crowd native water plants. Members of the public can stop the spread of this invasive species by recording any sightings on the iRecord App. Boaters and other users can also help by following the Check, Clean and Dry procedures.
