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.

comitan juniper

<em>Juniperus comitana</em>, commonly known as the Comitan Juniper, is a coniferous tree or shrub in the family Cupressaceae, native to Central America. This species is classified as Endangered on the IUCN Red List, reflecting significant population pressures across its restricted range. It typically inhabits temperate and boreal forest environments at higher elevations, often occurring in mountainous regions where cooler, drier conditions prevail. Like other members of the genus Juniperus, it often plays an important ecological role in its native habitat, providing cover and food resources for local wildlife. The Comitan Juniper faces ongoing threats from habitat loss due to deforestation, agricultural expansion, and land-use change within its limited geographic distribution. Its specialized requirements for higher-elevation forest environments make it particularly vulnerable to habitat degradation and climate-related shifts. Conservation efforts are critical to prevent further population decline of this Endangered conifer. Biological traits of this species remain poorly documented in the scientific literature.
