Gorse
Ulex europaeus
Also known as Common gorse
Why
Gorse can dominate low-stature indigenous vegetation and alter plant communities, while in some previously forested settings it can also provide a temporary nurse canopy for native forest regeneration.
Where
It occurs across disturbed and open habitats, but current extent, ecological effect and management priority are site-specific.
