Population study of Guaiacum sanctum L. (Zygophyllaceae) in the dry forests of Honduras

Abstract

Guaiacum sanctum, commonly called "lignum vitae", is characterized by its arboreal habit and distributed from the central part of South America to northern Mexico, southeastern United States and the Greater Antilles. Now it considered an endangered species according to the IUCN Red List and Appendix II of CITES. The aim of this study was to determine the distribution and structure of population in the remnants of dry forest in the departments of Comayagua, El Paraíso, Choluteca, Yoro and Olancho. From specimens deposited in herbarium and personal communications study sites was defined. 18 plots were demarcated and three age classes are defined. The vertical and horizontal structure was measured and adult individuals were georeferenced. The results indicate that the spatial distribution pattern is grouped in all categories and the percentage of juveniles is high. It is suggested that this regeneration is high because the population is spreading. The results of this study will be the basis for establishing a conservation strategy for this species as well as the proposed protected areas in the dry forest in Honduras.
