The effect of fire and topographic features on vegetation and soil properties in woodlands and grasslands transition in Córdoba mountains, Argentina. Under the currently context of climate change the dynamic of the transition zone between forests and grasslands has a fundamental role at both scientific level and in planning and ecosystem management. In this study, we evaluated the combined effect of fire, slope aspect and topographic position on vegetation and soil characteristics of the Córdoba Mountains in the transition zone between woodlands and grasslands. We selected four areas with different post-fire age. In each area we selected all possible combinations of slope aspects and topographic positions. In each site we performed floristic surveys and analyzed a composite sample of soil. Fire was the main factor associated with the different characteristics analyzed (physiognomy, floristic composition, soil characteristics), and separated burned from unburned sites. Slope aspect also contributed, conditioning physiognomy, floristic composition and soil characteristics. However we did not found a straight relationship between the recovery of tree cover and the time after the last fire, indicating that other factors such as geomorphology, land use history, and herbivory would also condition post-fire recovery of these systems. En el contexto actual de cambio climático, el estudio de la dinámica de las zonas de transición entre bosques y pastizales tiene un papel fundamental, tanto a nivel científico como en la planificación del manejo de los ecosistemas. En este trabajo evaluamos el efecto combinado del fuego, la exposición de ladera y la posición topográfica sobre la vegetación y los suelos en una zona de transición entre bosques y pastizales en las montañas de Córdoba. Para ello elegimos cuatro áreas con diferentes edades post-fuego. En cada sector seleccionamos todas las combinaciones posibles de exposición y posición topográfica. En cada sitio realizamos un relevamiento florístico completo y analizamos una muestra compuesta de suelo. El tiempo transcurrido después del último incendio fue el principal factor determinante de las distintas características analizadas (fisonomía, composición florística, riqueza y propiedades del suelo), diferenciando sitios quemados recientemente de los no quemados. La exposición de ladera también tuvo un rol importante condicionando la fisonomía, la composición florística y las propiedades de los suelos. Sin embargo, no encontramos una relación directa entre la recuperación de la cobertura arbórea y el tiempo transcurrido después del último incendio, indicando que otros factores como las características geomorfológicas, historia de uso y herbivoría, estarían condicionando la recuperación post-fuego de estos sistemas.
