Snowdonia Japanese Knotweed Survey

The Snowdonia National Park Authority (SNPA) is working with a number of partners to develop a strategy to control Japanese Knotweed within the Park.

Japanese Knotweed is an invasive species and is often located on  river banks. It is a threat to biodiversity and can cause damage to roads, houses and other infrastructure. Without efforts to develop strategies it will continue to spread. People within the park as well as professional and public bodies have been voicing their concern about the problem.

Using the COBWEB app has enabled SNPA to accurately map where Japanese Knotweed is located in certain areas of the park. Because of these high quality data, they have had the opportunity to devise a strategy and apply for funding.

Surveys created using the app are available in Welsh and English. Engagement has been with community groups, anglers associations, park wardens agricultural groups and societies, volunteer groups and educational groups.

Working with COBWEB in developing the phone app benefits the Snowdonia National Parks effort in eventually controlling Japanese Knotweed. It’s also hugely beneficial in an educational way connecting people within Snowdonia with their local environment.
