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 Oak

유럽에서 가장 중요하고 널리 분포하는 낙엽수 중 하나인 영국참나무(Quercus robur)는 1,000년 이상 살 수 있으며 높이 40m에 달하고, 어떤 유럽 수종보다 다양한 생물다양성을 지원한다. 2,300종 이상의 곤충·균류·지의류·이끼·조류가 노령 참나무에 직접 의존한다. 유럽 전역에서 서아시아에 이르는 온대림에 분포하며, 단단하고 내구성 있는 목재는 역사적으로 조선, 건축, 통 제조에 필수적이었다.
