Evolució de la vegetació de l’antic estany de Sils (la Selva) en els darrers 50 anys

The historical evolution of vegetation in the former Sils Pond (la Selva) during the second half of the 20th century is described through the study of past (Bolòs, 1954; Vilar, 1981) and present-day (Mercadal, 2002) vegetation cartography, the first aerial photographs (1956 and 1980) and current orthophotos (2000). This inland pool was finally drained in 1851 and most of its area was converted into meadows (Gaudinio fragilis-Arrhenatheretum elatioris Br.-Bl. in Br.-Bl., Roussine & Nègre 1952), a semi cultural community which was very distinct florally, for the Mediterranean region. The results demonstrate that in the last 50 years changes in land use have transformed the former landscape, which was prominently meadow-like and grain-producing, into woodlands, wet grasslands, developed areas and sub-Mediterranean forests, with the consequent loss of meadow areas and floristic diversity. In response, based on historical cartography, we propose spaces to prioritize for recovery and management such as meadow areas

Abstract: The historical evolution of vegetation in the former Sils Pond (la Selva) during the second half of the 20th century is described through the study of past (Bolòs, 1954; Vilar, 1981) and present-day (Mercadal, 2002) vegetation cartography, the first aerial photographs (1956 and 1980) and current orthophotos (2000). This inland pool was finally drained in 1851 and most of its area was converted into meadows (Gaudinio fragilis-Arrhenatheretum elatioris Br.-Bl. in Br.-Bl., Roussine & Nègre 1952), a semi cultural community which was very distinct florally, for the Mediterranean region. The results demonstrate that in the last 50 years changes in land use have transformed the former landscape, which was prominently meadow-like and grain-producing, into woodlands, wet grasslands, developed areas and sub-Mediterranean forests, with the consequent loss of meadow areas and floristic diversity. In response, based on historical cartography, we propose spaces to prioritize for recovery and management such as meadow areas
