Heterogenity of the vegetation of basaltic environments in central Argentina.
Heterogenity of the vegetation of basaltic environments in central Argentina. The flora and the vegetation of basaltic outcrops of Los Cóndores Mountains, central Argentina, are described. Plant communities were sampled following the Braun-Blanquet methods. The 98 relevés × 272 species matrix was cl...

Basaltic environments flora plant communities central Argentina. Heterogenity of the vegetation of basaltic environments in central Argentina. The flora and the vegetation of basaltic outcrops of Los Cóndores Mountains, central Argentina, are described. Plant communities were sampled following the Braun-Blanquet methods. The 98 relevés × 272 species matrix was classified through the ISOPAM method. The classification discriminated three main communities occurring in the three different substrates explored in this landscape: Rocky Islands (inselbergs), a Natural Matrix surrounding the Islands and an Agricultural Matrix, surrounding the whole basaltic area. The three communities differed in composition and physiognomy: the Islands were the less disturbed sites, reporting the highest plant species richness and diversity as well as the higher number of endemics, and the lowest number of exotic species. In the other extreme of the disturbance gradient, the AgriculturalMatrix showed the opposite patterns and is dominated by annual and perennial herbs, mainly weeds. While the number of aliens is low in the Islands and in the Natural Matrix, almost 50% of the species are exotic in the Agricultural Matrix. The results of this study reveal that the basaltic inselbergs are relevantsites for the conservation of the natural heritage. Se decribe la flora y la vegetación de pasiajes basálticos de la Sierra de Los Cóndores, Córdoba, Argentina. La vegetación se estudió según criterios de la escuela de Braun-Blanquet; la matriz de 98 inventarios × 272 spp. fue clasificada a través del método ISOPAM. El análisis discrimina tres comunidades correspondientes respectivamente a las tres geoformas relevadas en estos paisajes: Islas rocosas (inselbergs), la Matriz Natural que rodea a las Islas y la Matriz Agrícola que circunda al complejo de paisajes basálticos. Las tres comunidades difieren en su composición florística: las Islas rocosas son los sitios menos perturbados, más ricos en especies, con mayor diversidad, mayor número de especies endémicas y su fisonomía está dominada por formas arbustivas. En el otro extremo, la Matriz Agrícola es la más pobre en especies, la de menor diversidad y endemicidad, y predominan las hierbas perennes y anuales. Las Islas rocosas y la Matriz Natural registran bajos números de especies exóticas en su composición, mientras cerca del 50% de la flora de la matriz agrícola se compone de especies adventicias. Los resultados de este estudio revelan la importancia de las islas rocosas basálticas para laconservación del patrimonio natural de la provincia de Córdoba.

Heterogenity of the vegetation of basaltic environments in central Argentina. The flora and the vegetation of basaltic outcrops of Los Cóndores Mountains, central Argentina, are described.
