This number includes 21 transient and 4 locally naturalised species (Table 1), with ornamental plants predominating significantly. The locally naturalised species Cenchrus flaccidus, Cotoneaster zabelii, Doronicum pardalianches and Panicum virgatum are able to spread to native habitats and represent the greatest risk to native plant species in Slovakia.
