What is the Plant Swap Scheme?

As part of the Limestone Grassland Restoration Project, we aim to reduce the spread of invasive non native cotoneaster onto our extraordinary limestone grasslands. These grasslands are some of the most plant and insect-rich habitats in the UK and can have over 40 plant species per square meter.

Unfortunately, our limestone grasslands are at risk and now being smothered by cotoneaster- having a devastating effect on wildlife.

Acting as a seed source, garden cotoneaster is escalating this issue. Now considered in the top ten species having a negative impact on our protected sites in north Wales.

Identify the most dominant and invasive species of cotoneaster

Cotoneaster species are listed on the Schedule 9 to the Wildlife and Countryside Act 1981 England and Wales. Although still readily available to buy, it can be planted and contained in private gardens. However it is an offence to plant or otherwise cause these species to grow in the wild. GBNNSS

Stop the Spread

Most of our gardens contain plants that are not native to the UK - they originally came from another part of the world. While non-native plants can help us create beautiful ornamental displays to enjoy, if they escape into the wild some can become invasive.

Sign up and help reduce the spread of cotoneaster into the wild, by replacing your garden cotoneaster with a wildlife friendly alternative. Find our helpful tips of how to responsibly dispose of your unwanted cotoneaster below:

1. Place sheeting around the base of your unwanted cotoneaster - this will help catch any berries that may fall

2. Uproot or cut the cotoneaster using lopper or secateurs

3. Treat the exposed stumps with an appropriate herbicide

4. Take all material to a disposal centre that deals with non native invasive species, or safely and completely burn the material (details of permitted disposal sites: Natural Resources Wales)

Here’s a handy guide to "Gardening without harmful invasive plants" including cotoneaster alternative shrubs (page 30) to keep your garden buzzing.

The GB Non-Native Species Secretariat has created useful "Tips for gardeners to Be Plant Wise" a campaign to help choose what to grow, how to stop the spread of invasive plants and composting with care after removal.
