description |
On the basis of the digital edition of the “Atlas of the vascular flora of the Pyrenees” (www.florapyrenaea. org), the alpine flora of this mountain range is delimited in order to know its diversity and the different patterns of its spatial distribution, along with some other environmental characteristics. The Pyrenean alpine flora is made up of 645 taxa (630 species and 15 subspecies). All the administrative regions harbour more than 60% of the alpine plants, with Catalonia and Aragon reaching the highest values (around 90%). Along the altitudinal gradient, the highest plant diversity is found between 2300 and 2600 m. a. s. l., although 25% of the total alpine flora goes beyond 3000 m. On the other hand, a remarkable number of alpine plants live in the lowlands, and thus more than 300 alpine plants can be found below 1500 m. The average altitude range of the alpine plants is 1369 m, 300 m wider than that observed for the whole Pyrenean flora. Life-forms, habitat distribution and habitat naturalness of alpine plants are significantly different from those of the whole Pyrenean flora. Distribution of abundance categories also shows values of rarity significantly lower among alpine plants than for the whole flora. More than half the Pyrenean endemic plants are present in the alpine flora. High diversity and wide ecological amplitude of the alpine flora must be taken into account either when considering vulnerability of alpine plants facing “global change” or when addressing conservation policies for the whole Pyrenees from a common perspective. La reciente edición del “Atlas digital de Flora vascular de los Pirineos” (www.florapyrenaea.org) permite delimitar la flora alpina para conocer su diversidad, su distribución espacial y algunas características ambientales. La flora alpina de los Pirineos está formada por 645 taxones (630 especies y 15 subespecies). Todas las regiones administrativas muestran más del 60% de las plantas y Cataluña y Aragón tienen la mayor representación (sobre el 90%). En el gradiente altitudinal la mayor diversidad se encuentra entre 2300 y 2500 m, pero un 25% supera los 3000 m. Por otra parte, sorprende el número de plantas alpinas que se encuentran en los niveles altitudinales más bajos: más de 300 plantas viven por debajo de los 1500 m. El rango medio altitudinal de la flora alpina es de 1369 m, 300 m más amplio que el del conjunto de la flora pirenaica. Las formas biológicas, distribución por hábitats y naturalidad de los hábitats de la flora alpina es diferente significativamente del conjunto de la flora. Las categorías de abundancia difieren también significativamente y muestran un menor grado de rareza entre las plantas alpinas que en el conjunto de la flora. Más de la mitad de los endemismos pirenaicos están presentes en la flora alpina. La alta diversidad y amplitud ecológica de la flora alpina debe ser considerada a la hora de evaluar su fragilidad frente al “cambio global” y de definir políticas de conservación desde una perspectiva común para toda la Cordillera. |

The Pyrenean alpine flora is made up of 645 taxa (630 species and 15 subspecies). All the administrative regions harbour more than 60% of the alpine plants, with Catalonia and Aragon reaching the highest values (around 90%). Along the altitudinal gradient, the highest plant diversity is found between 2300 and 2600 m. a. s. l., although 25% of the total alpine flora goes beyond 3000 m. On the other hand, a remarkable number of alpine plants live in the lowlands, and thus more than 300 alpine plants can be found below 1500 m. The average altitude range of the alpine plants is 1369 m, 300 m wider than that observed for the whole Pyrenean flora. Life-forms, habitat distribution and habitat naturalness of alpine plants are significantly different from those of the whole Pyrenean flora. Distribution of abundance categories also shows values of rarity significantly lower among alpine plants than for the whole flora. More than half the Pyrenean endemic plants are present in the alpine flora. High diversity and wide ecological amplitude of the alpine flora must be taken into account either when considering vulnerability of alpine plants facing “global change” or when addressing conservation policies for the whole Pyrenees from a common perspective. La reciente edición del “Atlas digital de Flora vascular de los Pirineos” (www.florapyrenaea.org) permite delimitar la flora alpina para conocer su diversidad, su distribución espacial y algunas características ambientales. La flora alpina de los Pirineos está formada por 645 taxones (630 especies y 15 subespecies). Todas las regiones administrativas muestran más del 60% de las plantas y Cataluña y Aragón tienen la mayor representación (sobre el 90%). En el gradiente altitudinal la mayor diversidad se encuentra entre 2300 y 2500 m, pero un 25% supera los 3000 m. Por otra parte, sorprende el número de plantas alpinas que se encuentran en los niveles altitudinales más bajos: más de 300 plantas viven por debajo de los 1500 m. El rango medio altitudinal de la flora alpina es de 1369 m, 300 m más amplio que el del conjunto de la flora pirenaica. Las formas biológicas, distribución por hábitats y naturalidad de los hábitats de la flora alpina es diferente significativamente del conjunto de la flora. Las categorías de abundancia difieren también significativamente y muestran un menor grado de rareza entre las plantas alpinas que en el conjunto de la flora. Más de la mitad de los endemismos pirenaicos están presentes en la flora alpina. La alta diversidad y amplitud ecológica de la flora alpina debe ser considerada a la hora de evaluar su fragilidad frente al “cambio global” y de definir políticas de conservación desde una perspectiva común para toda la Cordillera.
