La flora del litorale pescarese come indicatore biologico dello stato ambientale e delle sue trasformazioni

Abstract The littoral flora of Pescara as a biological indicator of the environmental status and its modifications.—The flora of the Pescara littoral, and the vegetation, limited now to restricted areas in the outskirts, mainly near the mouth of the Saline river, and to the dunes, have been studied. Three hundred and six entities have been recorded and the abundance, the distribution, the biological forms and the phytogeographical elements have been described. The biological spectrum (P = 6, 14%; Ch = 5,41%; H = 32,5%; G = 10,46%; T = 45,49%) confirms a marked Mediterranean character. The considerable amount of trees and shrubs is due to the introduction of breakwinds and ornamental species. The analysis of the chorological elements confirms the dominance of the Mediterranean species; the ruderal polycore entities with the occasional naturalized alien species, reach about 25%. At Pescara their remarkable presence, which gives to the landscape the feature of a slum area, is the result of a great environmen...
