Cotoneaster on limestone grassland: a quiet ecological emergency
Wall cotoneaster and small-leaved cotoneaster are on Schedule 9 — and they are smothering some of the rarest grassland habitats in Wales and the West.
Cotoneaster is the most under-reported invasive on the UK list. Five species are on Schedule 9 but garden centres still sell ornamental cultivars, and birds carry the berries straight from suburban planting to limestone cliffs and grasslands where rare native flora is being smothered.
Where we see it
Welsh limestone outcrops in Gower and the Wye Valley, Mendip limestone in Somerset, Cotswold scarp grassland. Wherever there is a bird-perch overlooking a thin-soiled south-facing slope, cotoneaster will arrive within a few seasons of an upstream garden planting it.
Control
Hand-pull seedlings on accessible slopes. Cut mature shrubs to base in autumn, drill stump and apply approved glyphosate. Follow up for 3–5 years — the seed bank in nearby gardens keeps producing new arrivals.

- Guidance is general. Identification, treatment choice and timescales can only be confirmed by a site visit — photographs alone are indicative.
- Lender and insurer requirements vary by institution and change over time. We state what is typically accepted, not what any named lender will accept on your case.
- Guarantee (IBG) eligibility depends on the plan chosen, the survey findings and the underwriter's acceptance. It is not automatic.
- Legal points summarise published law and guidance current at the review date. They are not legal advice.
