dc.description.abstractBuxus vahlii Baillon is an endangered plant species endemic to Puerto Rico and St. Croix (USVI). There are six known populations, four in Puerto Rico (Rincón, Isabela, two in Bayamón) and two in St. Croix (Frederiksted and Christiansted). The status of these populations was studied to provide information on the ecology of the species. The species showed the ability to adapt to different environmental conditions. Such adaptations include shrubby growth in dry areas where it grows as part of the understory (Rincón, Frederiksted and Christiansted) vs. an arborescent growth form in high precipitation areas (Isabela and Bayamón). Identified human impacts on the studied populations were: development (Frederiksted), illegal immigrants and fires (Rincón), and rock climbing and introduced species (Bayamón). The Isabela and Christiansted populations were not impacted due to their low accessibility. Actualization of the management plan is suggested to reverse the decline of this species and restore the populations.en_US
dc.description.abstractBuxus vahlii es una planta en peligro de extinción endémica de Puerto Rico y Santa Cruz (Islas Vírgenes Americanas). Existen seis poblaciones conocidas, cuatro en Puerto Rico (Rincón, Isabela, dos en Bayamón) y dos en Santa Cruz (Frederiksted y Christiansted). Se estudió el estatus de estas poblaciones para proveer información respecto a la ecología de la especie. La especie muestra la habilidad para adaptarse a diferentes condiciones ambientales. Estas adaptaciones incluyen crecimiento arbustivo en áreas secas donde crece como parte del sotobosque (Rincón, Frederiksted y Christiansted) vs. un crecimiento en forma arborescente en áreas de alta precipitación (Isabela y Bayamón). Impactos humanos identificados en las poblaciones estudiadas fueron: desarrollo (Frederiksted), inmigrantes ilegales y fuego (Rincón), y escalamiento de rocas y especies introducidas (Bayamón). Las poblaciones de Isabela y Christiansted no se impactaron debido a su pobre acceso. Se sugiere la actualización del plan de manejo para revertir la declinación de la especie y restaurar las poblaciones.en_US
