| description | Background and Aims: The flora of the dry forest of Cerros del Tabacal and the semi-deciduous forest of Loma del Agua of the Reserva Forestal Guanito in the Cordillera Central of the Dominican Republic, is presented. There are few species records of this reserve. Hence, the main objective was to inventory the vascular flora of both hills, and the specific objectives, to determine the diversity and richness of species in the Reserva Forestal Guanito and to document the biogeographic, conservation status, and life forms, and to register the floristic composition variation.
Methods: Three plots of 10 × 10 m and two transects of 60 × 2 m were made on each hill, based on the species expression minimum area, and they were located in the areas with dense plant cover. The Shannon diversity index, Berger-Parker dominance index and Jaccard similarity coefficient were calculated.
Key results: In the dry forest 81 species were recorded, distributed in 72 genera and 31 families; in the semi-deciduous forest, 110 species belonging to 96 genera and 50 families were registered. Fabaceae was the richest family in genera number on both hills (eight and nine, respectively), and Tillandsia the richest genus in species number (six and five, respectively). Tillandsia recurvata stands out with the highest abundance of individuals (173 individuals) in the dry forest, and Savia sessiliflora (39) in the semi-deciduous forest. The Shannon index showed that the semi-deciduous forest has more diversity than the dry forest, and the results of the Jaccard coefficient indicated that both hills have a highly differentiated floristic composition.
Conclusions: This study reaffirms the importance and floristic richness of the forests of the Domincan Republic and at the same time constitutes the first floristic inventory for the Reserva Forestal Guanito. |

Antecedentes y Objetivos: Se presenta la flora del bosque seco de Cerros del Tabacal y del bosque semideciduo de Loma del Agua de la Reserva Forestal Guanito en la Cordillera Central de República Dominicana. Existen muy pocos registros de las especies de esta reserva. Por ello, el objetivo general fue inventariar la flora vascular de ambas montañas; los objetivos específicos, determinar la diversidad y riqueza de especies en la Reserva Forestal Guanito, documentar su distribución, estado de conservación y formas de vida, y registrar la variación en la composición florística. Métodos: Se delimitaron tres parcelas de 10 × 10 m y dos transectos de 60 × 2 m en cada bosque, basados en el área mínima de expresión de las especies, y fueron ubicados en las áreas con cobertura vegetal densa. Se calculó el índice de diversidad de Shannon, el índice de dominancia de Berger-Parker y el coeficiente de similitud de Jaccard. Resultados clave: En el bosque seco se registraron 81 especies, distribuidas en 72 géneros y 31 familias; en el bosque semideciduo, 110 especies de 96 géneros y 50 familias. Fabaceae fue la familia con mayor riqueza de géneros en ambos cerros (siete y ocho, respectivamente), y Tillandsia el género con mayor riqueza de especies (seis y cinco, respectivamente). Con mayor abundancia de individuos destacó Tillandsia recurvata (173 individuos) en el bosque seco y en el bosque semideciduo, Savia sessiliflora (39). El índice de Shannon mostró que el bosque semideciduo tiene mayor diversidad que el bosque seco, y los resultados del coeficiente de Jaccard indican que ambos bosques presentan una composición florística muy diferente. Conclusiones: Este estudio reafirma la importancia y riqueza florística de los bosques de República Dominicana y constituye el primer inventario florístico para la Reserva Forestal Guanito.
