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.

Coffee

Coffee (Coffea arabica) is a woody shrub or small tree in the family Rubiaceae, native to the montane forests of Ethiopia and Yemen, where it was discovered and first cultivated before spreading globally to become one of the world's most economically important crops. Plants grow 2–10 metres tall in the wild but are typically pruned to 2–3 metres in cultivation, producing glossy elliptical leaves and clusters of fragrant white flowers followed by cherry-like drupes that ripen from green through yellow to deep red. Each fruit contains two seeds—the coffee beans—surrounded by layers of sweet pulp, parchment, and silver skin. Coffea arabica is a diploid tetraploid (2n = 44) that produces smoother, more aromatic coffee than its sibling species Coffea canephora (Robusta). Wild populations in Ethiopian highland forests represent an important reservoir of genetic diversity for the global coffee industry and are threatened by deforestation and climate change, which is altering the geographic suitability of arabica cultivation. Commercial plantations extend from Colombia, Brazil, and Central America through East Africa to India, Indonesia, and Vietnam. As a shade-tolerant understorey plant in its native montane habitat, Coffea arabica supports biodiversity in agroforestry systems. Despite its vast cultivation, wild arabica populations face significant conservation concern.
