Attalea nucifera is an acaulescent palm native of Colombia that is in risk of extinction. Between 2016-2017 we evaluated the structure and density of populations in six localities of the Magdalena river valley, and studied the population dynamic in the locality of Guaduas, Cundinamarca (VC). Although the population structure differs among locations (X2 = 1819, gl = 25, P < 0.05), populations tend to group according to the degree of habitat perturbation. In four localities an inverted J population structure was observed. A matrix population model showed a finite growth rate (λ) of 0.979 (CI95 % = 0.962–0.997). The demographic processes of the permanence of seedlings, sub-adults and young adults show more elasticity. A transient dynamic simulation projected to 30 years shows that under the scenarios of paddock and cattle lopping the population size decrease drastically. The extinction threshold calculated for the population in the locality VC is of 145 years, but paddock and cattle lopping activities can reduce it to less than 40 years. Although Attalea nucifera persists in very disturbing locations in the Middle Magdalena Basin, the results of population dynamics in the locality VC suggest that it could be less tolerant of environmental disturbances. Thus, it is necessary to increase our knowledge of its population dynamics, as well as seed germination and seedling establishment in different disturbance conditions.

Attalea nucifera es una palma nativa de Colombia que está en riesgo de extinción. Entre 2016-2017 se evaluó la estructura y densidad de las poblaciones en seis localidades del valle del río Magdalena, y se estudió su dinámica poblacional en una localidad de Guaduas, Cundinamarca (VC). Si bien la estructura poblacional difiere entre localidades (X2 = 1819, gl = 25, P < 0,05), las poblaciones tienden a agruparse de acuerdo al grado de perturbación del hábitat. En cuatro localidades se observó una estructura poblacional en forma de J invertida. El modelo matricial muestra una tasa finita de crecimiento poblacional (λ)) de 0,979 (IC95 % = 0,962–0,997). El proceso demográfico de permanencia de las plántulas, de subadultos y de adultos jóvenes tuvo la mayor elasticidad. La dinámica transitoria proyectada a 30 años muestra que bajo los escenarios de potrerización y ramoneo del ganado el tamaño de la población disminuye drásticamente. El umbral de extinción calculado para esta población (VC) es de 145 años, pero las actividades de potrerización y ramoneo del ganado pueden reducirlo a menos de 40 años. Aunque Attalea nucifera persiste en localidades muy alteradas del Valle del Magdalena Medio, los resultados de la dinámica poblacional en la localidad VC sugieren que podría tener baja tolerancia a disturbios ambientales. Por lo cual es necesario incrementar nuestro conocimiento de la dinámica poblacional, así como la germinación de semillas y el establecimiento de plántulas en diferentes condiciones de disturbio.
