Coastal Ragweed

Coastal ragweed (Ambrosia hispida) is a perennial herb in the family Asteraceae, native to the coastal dunes, sandy beaches, and cays of Cuba, the Bahamas, and the wider Caribbean region. It grows in pioneer beach and dune vegetation, often forming spreading colonies that help stabilise loose coastal sands. Like other members of the genus Ambrosia, it bears inconspicuous greenish-white flowers arranged in racemes; male flower heads produce wind-dispersed pollen that can trigger allergic rhinitis in sensitive individuals. The deeply lobed, hispid leaves are adapted to reflect intense solar radiation and tolerate salt spray. Coastal ragweed plays an ecological role in early dune succession, binding sand and enabling other plant species to establish. The genus is widespread globally, with several Ambrosia species considered noxious weeds in agricultural settings, though Ambrosia hispida is restricted to its native Caribbean coastal range. The IUCN assesses it as Least Concern, reflecting adequate population size across its Caribbean coastal distribution. Pressure from coastal development and tourism infrastructure poses a localised threat to dune communities it inhabits.

Common Currant

<em>Ribes rubrum</em>, commonly known as common currant or red currant, is a deciduous shrub in the family Grossulariaceae. It is native to western Europe and parts of Asia and has been widely cultivated and naturalized across North America and South America. Common currant typically grows in moist, fertile soils in woodland edges, hedgerows, riverbanks, and disturbed habitats. The species produces clusters of small, translucent red berries that are rich in vitamin C and commonly used in jams, jellies, juices, and desserts. Its lobed leaves resemble those of maple and turn yellow in autumn. The flowers are small and inconspicuous, borne in pendulous racemes in spring. Red currant is an important food source for birds and small mammals. The species is assessed as Least Concern by the IUCN. Biological traits of this species remain poorly documented in the scientific literature.
