摘要

棕榈Astrocaryum malybo是一种濒危物种,生长在哥伦比亚加勒比海低地的森林遗迹中,它的矛叶为蓬勃发展的手工活动提供纤维。本文研究了塞萨尔奇米查瓜镇附近的棕榈种群结构和动态,以期为其管理和保护提供必要的生态信息。利用积分预测模型对不同管理模式下未来20年的人口增长和纤维产量进行了模拟。虽然幼苗比例低,种群结构多变,但种群在未来20年内仍将继续增长,年增长率为7.1%,可产生35片矛叶/公顷/年的手工活动。对该模型的模拟表明,种群易受影响个体生存的变化的影响;每公顷每年只要移走34棵任何大小的棕榈树就会导致种群减少,矛叶产量也会相应下降。相反,任何幼苗生长或存活的增加都会导致种群的增长。如果管理得当,马柳杉是保护哥伦比亚加勒比海低地干旱森林遗迹的关键物种。

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.
