(Source Eden Rivers Trust PR) A staggering 500 volunteers have spent more than 2000 hours helping Eden Rivers Trust battle against invading non-native species in the Eden Valley during 2013. Without their help invaders such as signal crayfish and Himalayan balsam would go unchecked, causing problems for the animals and plants that naturally live in and alongside rivers and lakes.
In total the volunteers have contributed to:
- clearing 16 miles (26 km) of riverbank and lake shore of balsam, along with 11.5 hectares (28 acres) of adjoining land;
- managing 1100 m2 of newly discovered Japanese knotweed;
- continuing the management of Japanese knotweed at sites managed in 2012;
- removing 899 signal crayfish;
- eradicating 300 giant hogweed plants which were sprayed, injected or dug up and composted.
The project has been funded by the Environment Agency and Natural England.
Paul Greaves, Invasive Species Officer at Eden Rivers Trust, said, “We are extremely grateful to all the volunteers involved because they have made a significant contribution to the conservation of the waterways and wildlife of the River Eden system. We look forward to carrying on the good work in 2014!”
Many of the volunteers this year have been under 18 years old and it has been a fantastic opportunity for them to learn about invasive species and how they are introduced and transported. They have also heard about the simple biosecurity steps that can be taken to reduce the chances of it happening. As introduction is often through hitch hiking on equipment or clothes, when people move from one water body to another, the Checking Cleaning and Drying of equipment is essential to minimise the risk of carrying seeds, plant fragments or animals themselves to areas that they shouldn’t be taken.
- Are you spreading invasive species via your water sports equipment and clothing?
Invasive species can affect fish and other wildlife, restrict navigation, clog up propellers
and be costly to manage. You can help protect the water sports you love by following
three simple steps when you leave the water. Check, Clean and Dry your equipment before you visit the next body of water.
Not all invasive species are introduced unintentionally. Some are still sold in garden centres and escape from the gardens where they are planted. One such plant is American skunk cabbage which has a large yellow flower, a pungent smell and can dominate wet boggy areas. This plant has been identified in several areas locally this year and chemical treatment has been carried out to prevent it taking over, as it has done in other parts of the UK.
People are asked to bear this in mind when next buying plants for their garden or pond. If any advice is required they can get in touch with the Trust or look at the “Be Plant Wise” campaign on the internet.
