Abstract :

En este trabajo se presentan la cartografía, la sintaxonomía y la sindinámica de las comunidades vegetales. Se han identificado 17 asociaciones vegetales y se han descrito para cada una de ellas su posición sucesional. Se describen 6 tipos de unidades de vegetación natural potencial y se representan cartograficamente las distintas tipologías de cobertura del suelo (escala 1:25.000). La combinación original de los taxones en las distintas comunidades vegetales nos ha llevado a proponer dos nuevas asociaciones: Calicotomo villosae-Rubetum ulmifolii (manto mesofitíco) y Brassico fruticulosae-Brachypodietum retusi (pastizal secundario), y tambien dos nuevas subasociaciones. Si bien los bosques residuales de la isla son muy fragmentarios y necesitan una protección particular ante los efectos del fuego, la elevada diversidad específica y de comunidades vegetales evidencian el elevado valor naturalístico del paisaje de Ponza. Cartography, syntaxonomy and syndynamics of plant communities of Ponza island are discussed. Seventeen plant associations have been identified and their successional position was pointed out. Six potential natural vegetation units were described and the different land cover types for each units were mapped (scale 1:10 000, printed at scale 1:25.000) and evaluated. The originality of taxa combination in the plant communities allowed us to propose two new associations, (Calicotomo villosae-Rubetum ulmifolii (mantle) and Brassico fruticulosae-Brachypodietum retusi (secondary grassland), as well as two new subassociations. Although the residual woods are very fragmented and need a special protection against fires for their survival, the Ponza landscape has an important naturalistic and ecological value due to its high diversity of plant taxa and plant communities.
