Abstract
En las últimas décadas, muchos pinares ibéricos han sido definidoscomo «repoblaciones antiguas», calificativo y a la vez argumento muy repetido en el campo de la fitosociología y la botánica en general, con el que numerosos autores han negado que tengan cualquier papel en la vegetación natural. Esto es lo que ha ocurrido con gran parte de las masas de pino albar (Pinus sylvestris L.) del Sistema Central. Sin
embargo, los datos palinológicos e históricos revelan que la presencia de los pinares, en lugares donde se afirma que no son naturales, es muy antigua; también muestran una disminución progresiva de su ex tensión a lo largo de la historia y además, la ausencia de «repoblaciones antiguas» encaminadas a extender artificialmente su área de distribución. Por todas estas razones debemos descartar el argumento de las «repoblaciones antiguas» aplicado a la interpretación geobotánica de los pinares albares del Sistema Central. Asimismo el uso in discriminado del calificativo «de repoblación» como sinónimo de «introducido o alóctono» aplicado a muchos pinares, ha producido equívocos y graves errores de interpretación que es necesario corregir
estudiando la vegetación que había antes de realizar la reforestación y así saber qué formaciones están en sus áreas naturales y cuales no, independientemente del manejo antrópico al que hayan sido sometidas
During the last decades, many Iberian pine forests have been defined as «old reforestations». This is an epithet and also an argument cons tantly repeated in the field of phytosociology and in botany on the who le, which has been used by many authors to deny any possible role of pine woodlands upon the natural vegetation. This is what has happe ned with most of the Scotch pine (Pinus sylvestris L.) forests from the Central Mountain System. However, palynological and historical data show that pine woodlands have an age-old presence in areas where they are not considered as natural; these data also show a progressi ve area decrease during the history, and also, the lack of «old refores tations» aimed to artificially extend its distribution area. For all these reasons, the «old reforestations» argument used for the geobotanical interpretation of the Scotch pine forests from the Central Mountain System must be rejected. In like manner, the indiscriminate use of the term «reforestation» as a synonym of «introduced or aloctonous», which has been used for many pine woodlands, has led to some misunders tandings and serious interpretation mistakes which must be corrected studying the vegetation existing before the reforestation was made. That way it would be possible knowing what formations are in their natural range and what are not, regardless the anthropic use they have been subjected to
