FLOREZ-P., Mónica  e  RAZ, Lauren. Population structure and spatial pattern of Brosimum alicastrum in the dry forest of the Caribbean region of Colombia. Caldasia [online]. 2019, vol.41, n.1, pp.152-164. ISSN 0366-5232.  https://doi.org/10.15446/caldasia.v41n1.71307.

Brosimum alicastrum is one of the most abundant tree species in the dry forest of the colombian Caribbean. This is highly nutritious source that has local use in the region and is of potential commercial interest. The present study provides information of its population structure and spatial distribution, in two points located in Dibulla (Guajira) and Santa Catalina (Bolívar), in the colombian Caribbean. Six plots were made in La Guajira and one plot in Bolívar, each one 10 000 m2. All the individuals were counted and measured, taking a series of variables that allowed to be classified in six size categories, and they were georeferenced to be able to make maps that show the spatial distribution of the individuals. The populations of Brosimum alicastrum in the two localities behave differently. Based on the distribution of individuals in the different size categories, three types of population structure patterns could be distinguished: Type I and Type II Patterns were found in La Guajira and Type III Pattern, in Bolívar. The spatial distribution is aggregated in La Guajira and uniform in Bolívar. The data and records from this research can be used not only to provide guidelines for the management and use of this non-timber forest resource, but also for the management and conservation of forests, especially the tropical dry forest, considered one of the most fragile ecosystems in the country.
