The Kenfig National Nature Reserve (Kenfig) is a beautiful Site of Special Scientific Interest (SSSI) in South Wales. I visited Kenfig recently as a project officer for the Wales Resilient Ecological Network, to see how they are tackling invasive non-native species (‘invasive species’). Invasive species are non-native species that have been intentionally or unintentionally introduced beyond their natural range by humans. Their spread threatens native biodiversity and can cause damage to the environment, economy, and our health.

Kenfig covers approximately 1,300 acres and includes an area of sand dunes and Kenfig pool, Glamorgan’s largest natural lake. The reserve is home to many amazing orchids, bird and insect species, whose survival depend on this unique habitat. Kenfig also contains many rare and endangered species, some of which, for example Sea Stock (Matthiola sinuata), can only be found in a few places in the UK!

The reserve is currently managed by Kenfig Corporation Trust, with the aim of preserving the rich diversity of habitats and wildlife found there.

Invasive species threaten the integrity of the reserve’s stunning, yet fragile, ecosystems. This is why it is very important to control any invasive species on the reserve and prevent any further introductions. Currently there are a number of invasive plants found on or near the reserve: American skunk cabbage (Lysichiton americanus), Himalayan balsam (Impatiens glandulifera), Japanese knotweed (Reynoutria japonica), Japanese rose (Rosa rugosa), Cotoneaster species, and sea buckthorn (Hippophae rhamnoides). These populations are being continuously monitored and measures are being undertaken with the help of volunteers to control and remove these species.

Good biosecurity practices are essential to prevent any further introductions or spread of invasive species. It is vital that you do not accidently bring any species on to the reserve, which is easily prevented by checking that all of your clothing and footwear are clean and dry. For more information on good biosecurity practice see the Check Clean Dry campaign! You can learn more about the wildlife and habitats found at Kenfig National Nature Reserve and get involved with their invasive species management through ‘Wildlife Wednesdays’ and ‘Practical Thursdays’ run from 10am-3pm every week!
