The Invasive Species sub-group is working with the Yorkshire Wildlife Trust to maintain and improve the environment around the Beck. Eliminating Japanese Knotweed is one of the main aims of the group.
Japanese Knotweed is Europe’s most invasive plant species. It spreads very easily, grows very quickly and is very hard to kill. Once established, it drives out native species, damages hard surfaces and can reduce the capacity of water channels, with a consequent flood risk. The weed is amongst those listed by the Wildlife and Countryside Act of 1981 putting constraints on how to treat the weed and dispose of the remains.
The Invasive Species Group plans to walk the banks of the Beck during the summer locating and mapping the strands of weed then go back and treat in the autumn, using environmentally safe methods. There are over 40km of open water so we need lots of volunteers. Equipment provided but bring a camera/phone, packed lunch and your own boots!
A map showing the extent of the Japanese Knotweed invasion is available here.
