(Aizoaceae), a prominent invasive plant in Europe.
Carpobrotus species are mat-forming trailing succulent perennial herbs native from South Africa, introduced in Europe for ornamental and soil stabilization purposes since the beginning of the seventeenth century, now widely naturalized on coastal habitats of southern and western Europe. C. acinaciformis and C. edulis are the main species recognized outside South Africa, together with their hybrids and potential hybrid swarms. Identification conflicts both in the native and invaded areas raise doubts on the taxonomy of these taxa, but hybridization processes may boost adaptive changes in the invaded range.
The release of Carpobrotus in natural environments and protected areas is prohibited in several European countries, but this taxon is not included in the list of invasive species of Union concern. Carpobrotus is a pioneer of disturbed sites and coastal areas including cliffs and sand dune systems, due to its tolerance to stress factors such as salinity, drought and excess of light. Carpobrotus invasion ultimately affects patterns of native species diversity. Moreover, it has been recognized as a major driver of soil conditions shifts and soil geochemical processes disruptions, representing a serious threat for coastal habitats.
Management plans for Carpobrotus must consider its high plasticity for morphological and ecophysiological traits, which may probably explain its tolerance to a wide range of ecological conditions. Its flexible mating systems, which represent an optimal strategy to facilitate local adaptation and habitat colonization, include ability to produce apomictic seeds, self- and cross-pollination, and an intense vegetative clonality. In addition, Carpobrotus produces a large seed bank with a moderate short-term persistence, and fruits are effectively dispersed by mammals. The most efficient control methods are physical removal and herbicide application on leaves, whereas integration of biological control with other conventional management methods are likely to be most effective. A long-term monitoring of control actions and restoration of soil conditions are needed to prevent recovering from clonal parts, seed bank or mammal faeces as well as potential new invasions by other opportunistic species."

[ZG] EuropeMots-clés : plante invasive biogéographie écophysiologie impact environnemental mesure de gestion biologie de la reproduction aire de répartition Résumé : "This account presents information on all aspects of the biology and ecology of Baccharis halimifolia L. that are relevant to understanding its invasive behaviour. The main topics are presented within the framework of the new series of Botany Letters on Monographs on invasive plants in Europe: taxonomy, distribution, history of introduction and spread, ecology (including preferred climate and habitats, responses to abiotic and biotic factors, ecological interactions), biology (including physiology, phenology and reproductive biology), impacts and management. Baccharis halimifolia L. (Asteraceae), groundsel bush, is a broad-leaved shrub native to the coastal area of southeastern North America. Introduced for ornamental and amenity purposes during the nineteenth century, it has become naturalized in several coastal habitats, as well as in disturbed areas of western Europe. The shrub is now common on the Atlantic coast of Europe from northern Spain to Belgium and it is an emerging problem on the Mediterranean coast. Baccharis halimifolia is a light-demanding pioneer species that colonizes following disturbance but can then become dominant in natural habitats. The shrub can grow on a large range of soil types but prefers moist soils with high organic content and it is well adapted to poorly drained saline soils. In contrast to its native range, where it is in competition with other coastal shrubs, populations in the secondary range have almost no native analogues across most of its ecological niche except for Tamarix gallica in Mediterranean areas. Baccharis halimifolia reproduces sexually, but it has a high resprouting ability following mechanical damage or fire. Very high seed production, coupled with dispersal by wind and water, ensure a good colonization capacity of suitable habitats. The species shows a relatively high plasticity for both morphological and ecophysiological traits, which is probably the basis for its tolerance to a wide range of ecological conditions, including salinity and light availability. Baccharis halimifolia is host to a limited number of insects, both in the native and introduced ranges, but a number of highly specific agents have contributed to the control of this plant following its introduction to Australia. In Europe, B. halimifolia is considered an invasive non-indigenous plant and the shrub is the object of control programmes. Negative impacts include the addition of a new canopy layer in formerly open habitats (e.g. Juncus maritimus communities), which causes a strong decrease in species richness and herbaceous cover and poses a threat to some birds by modifying habitat quality, mainly in priority habitats and in many natural protected sites. Most efficient control methods are mechanical removal and herbicide application either on leaves or stumps. Due to the high cost of mechanical removal and the unintended effects of herbicide application on other species, alternative management methods such as controlled inundations and biological control could also be considered. The plant is legally prohibited in several countries and it is prelisted on EU Regulation 1143/2014."
