Demografía de Astrocaryum malybo H.Karst. (ARECACEAE) en Colombia, recomendaciones para su manejo y conservación
The palm Astrocaryum malybo is an endangered species growing in forest remnants in the Caribbean lowlands of Colombia, where its spear leaves provide fiber for a flourishing artisanal activity. We studied the palm’s population structure and dynamics near the town of Chimichagua, Cesar, in order to provide ecological information required for its management and conservation. We modeled population growth and fiber production in the next 20 years under different management scenarios using Integral Projection Models. Although there was a low proportion of seedlings and population structure was variable, population would grow for the next 20 years, with an annual growth rate of 7.1%, yielding ca. 35 spear leaves/ha/year for artisanal activity. Simulations on the model show that the population is susceptible to alterations that affect the survival of individuals; removal of as few as 34 palms of any size per ha/year would cause the population to decrease, and spear leaf production will decline accordingly. Conversely, any increase in seedling growth or survival would lead to population growth. If properly managed, A. malybo is a key species for conservation of the dry forest relicts in the Caribbean lowlands of Colombia.

期刊介绍:
Colombia Forestal Journal publishes original manuscripts on themes of the forest field and various aspects of natural resources and the environment, which are discriminated in the categories of research article, review, reflection and technical notes of agreement with the stipulations of COLCIENCIAS for scientific publications. According to the classification of scientific areas of the Organization for Economic Cooperation and Development (OECD), Colombia Forestal Journal belongs to the large area of Agricultural Sciences (4), Agriculture, Forestry and Fisheries (4A) and to the discipline Forestry (4A02). Since its creation in 1978, the journal has been edited and published by the Francisco José de Caldas District University with headquarters in Bogotá. The quality of the content of the journal has been strengthened with the collaboration of national and international external evaluators in a double blind arbitration system and the dissemination has been extended by publishing manuscripts in a language different from Spanish and with inclusion in bibliographical databases such as Scopus. , DOAJ, Scielo, Redalyc, Ebsco, CAB Abstracts of CAB International, Forestry Abstracts, Ulrich''s, Latindex, Publindex. Likewise, it has academic profiles at Mendeley, Academia and Researchgate. The articles that are submitted to Colombia Forestal Journal must be original and unpublished and have not been postulated in other journals.
