Phenology and Habitat Characterization of the Endangered Species Chamaecrista glandulosa var. mirabilis (Leguminoseae: Cesalpinioidea).
For the last years the anthropological influences to the silica sands of the northern area of Puerto Rico have affected the habitat of many species like Chamaecrista glandulosa var. mirabilis. One of the last populations of this endangered species endemic to Puerto Rico is established at the Laguna Tortuguero Natural Reserve. Therefore, the critical status of this species makes the knowledge of the phenological patterns an important concern for the plant population success and for conservation efforts. The aim of this study was to determine the reproductive phenological stages and habitat characterization of this species. In order to ascertain this, in each visit to the study area, the buds, flowers, and fruits of each plant were counted. Also a climatological station was established and microhabitat climate was recorded. The study revealed a higher production of buds during October and February while the flowering and fruiting production peaked in February and March. Nevertheless, a high production of buds as compared to a lower production of flowers and fruits suggest a poor reproductive success.
