Background and aims: The Tandilia rangelands represent sites of high bio and geodiversity, however, plant communities are threathened by invasion of exotic species. This study aims to characterize and compare the floristic composition and richness of the different geoforms on northeastern and southwestern slopes in two hills in the districts of General Pueyrredon and Balcarce, with different degrees of invasion of Acacia melanoxylon.
M&M: A stratified sampling by geoform was carried out, on both slopes, in a hill with low (in Balcarce) and high (in General Pueyrredon) percentage of invasion of A. melanoxylon, where richness and coverage of vascular plants was measured. A phytosociological analysis, a correspondence analysis and a comparison of richness by geoform and slope were carried out.
Results: We identified 187 species whom 80,75 % were native to Pampa ecorregion. Poaceae and Asteraceae were the more diverse recorded families. Floristic composition partially vary with different geoform and A. melanoxylon invasión. The Upland, Slopes and Colluvial deposits present the richest communities. No differences were observed between northeast and southwest slopes.
Conclusions: The floristic characterization and richness patterns reported, provide valuable information on the influence of geomorphological variability and the presence of invasive species in the two mountain ranges of southeastern Tandilia for consideration in the conservation of the mountain biota. |

Introducción y objetivos: Las sierras de Tandilia son altamente bio y geodiversas, sin embargo, la vegetación se encuentra amenazada por la invasión de especies exóticas como Acacia melanoxylon R. Br. En este trabajo se caracterizó y comparó la composición florística y la riqueza de las distintas geoformas en laderas noreste y sudoeste en dos sierras de General Pueyrredon y Balcarce, con distinto grado de invasión de A. melanoxylon. M&M: Se realizó un muestreo estratificado por geoforma, en ambas laderas, en una sierra con bajo (en Balcarce) y alto (en General Pueyrredon) porcentaje de invasión de A. melanoxylon, donde se midió riqueza y cobertura de las plantas vasculares. Se realizó un análisis fitosociológico, de correspondencia y una comparación de la riqueza por geoforma y ladera. Resultados: Se identificaron 187 especies, 80,75 % nativas de la Ecorregión Pampa, predominando las familias Poaceae y Asteraceae. La composición florística presentó parcial correspondencia con diferentes geoformas del perfil serrano e invasión por A. melanoxylon, siendo Cumbre, Vertiente rocosa y Depósitos coluviales las más ricas. No se observaron diferencias entre laderas noreste y sudoeste. Conclusiones: La caracterización florística y patrones de riqueza reportados, brindan información valiosa sobre la influencia de la variabilidad geomorfológica y presencia de especies invasoras en las dos sierras del sudeste de Tandilia para su consideración en la conservación de la biota serrana.
