The objective of this work is to analyze the changes in the forest structure of the plant communities in the center of Córdoba, its dynamics, and regeneration along a time lapse of six years, evaluating the effect of cattle and precipitations. In 16 sites located in the Natural Reserve of the Defensa La Calera the woody species and their regeneration were surveyed (2013, 2016, 2019) in four different plant communities. Cattle was excluded from seven sites and it was present in low loads in the other nine (~12 ha EV-1). The local standardized precipitation indexes were calculated. The cattle exclusion did not lead to higher regeneration. In the communities a positive evolution towards maturity was observed, with the most dynamic communities being those of Sebastiania. In the deforested areas, Geoffroea decorticans and Schinus fasciculatus present an important survival rate and growth speed. In Vachellia and Schinopsis communities the regeneration follows the precipitation dynamics. According to the results, passive revegetation is an important recovery strategy in natural and semi-natural environments of the center of Córdoba.   Para evaluar la revegetación natural como estrategia de restauración debe comprenderse la dinámica, estructura y regeneración de las comunidades vegetales. El objetivo de este trabajo es analizar los cambios en la estructura forestal de comunidades vegetales del centro de Córdoba, su dinámica y regeneración en el lapso de seis años, evaluando el efecto del ganado y las precipitaciones. En 16 sitios de la Reserva Natural de la Defensa La Calera se relevaron especies forestales y su regeneración (2013, 2016, 2019) en cuatro comunidades vegetales diferentes. Se excluyó el ganado vacuno de siete sitios y en los nueve restantes estuvo presente en bajas cargas (~12 ha EV-1). Se calcularon los índices de precipitación estandarizados locales. La exclusión del ganado no se tradujo en mayor regeneración. En las comunidades se observó una evolución positiva hacia la madurez, siendo las más dinámicas las de Sebastiania. En las áreas deforestadas, Geoffroea decorticans y Schinus fasciculatus presentan una importante tasa de sobrevida y velocidad de crecimiento. En comunidades de Vachellia y Schinopsis la regeneración sigue la dinámica de las precipitaciones. De acuerdo a los resultados, la revegetación pasiva es una estrategia importante de recuperación en ambientes naturales y semi-naturales del centro de Córdoba.
