Selecting competitive species for restoring native assemblages can provide successful outcomes in managing risks associated to invasive species like gorse. We argue that invasions can differentially affect the components of natural forest–grassland mosaics, which could have long-term consequences. The seed pods often open explosively, vaulting the seeds to some distance away. Scotch broom reproduces vegetatively and by seed. The green branches are sharply angled with five green ridges, and they are hairy when young and without hairs as they mature. Woody species were more abundant in the understory of gorse canopies than in areas beside gorse canopies, whereas the cover of grasses decreased under gorse canopies. Scotch broom is a bushy, drought-deciduous shrub that grows three to six feet tall. Assemblages in the understory of gorse canopies were comparatively species-poor and more homogeneous than beside gorse canopies. Gorse canopies exerted significant effects on community structure and composition. Gorse cover in relatively undisturbed areas, such as ungrazed natural grasslands, was found to be variable, although the physiognomy and structure of mosaic ecosystems was still affected. Vulnerability to gorse invasions was highest in heavily grazed grasslands, where gorse canopy cover often reached 50 %. At the community scale, we examined the effects of proximate gorse canopies on plant community abundance, diversity, and composition. We studied the influence of landscape mosaic structure and land use on gorse distribution. However, knowledge of its effects on ecosystem and community structure is still missing from most areas of its invasive range, including species-rich ecosystems such as the forest–grassland mosaics of southern Brazil. There are three similar species of gorse in the UK: common gorse is widespread and flowers form January to June western gorse flowers in late summer and autumn and is mainly. Gorse (Ulex europaeus L., Fabaceae) is an invasive species of worldwide concern. Common gorse is a large, evergreen shrub, covered in needle-like leaves and distinctive, coconut-perfumed, yellow flowers during the spring and summer.
