Pollen deposition in country villages of Eastern Liguria (Northern Italy)

Abstract

Recent pollen rain in 14 cotmoy villages of Ligmian hinteHand was examined, in the fi'amework of pollen deposition studies based upon moss polsters analysis, now in progress. The above mentioned localities are prevailingly situated in the Trebbia, A veto and Vara valleys, within 300 and 1000 m a.s.l. For each Iocali O, a moss sample was examined (two for Torriglia: north and south) consisting of several sub-samples fi'om various zones of the builtup area. All the samples have proved rich in pollen and provided spectra in accordance with qualitative and quantitative featttres of the urbanized areas vegetation and the spontaneous one of the neighbourhood. Sticking to general considerations, an attempt was made to compare the present results with those of the ci O, area of Genova, previously obtained ~4th the same methods'.

Assessment of Pollen Representation in NW Italy (Liguria and Piedmont)

“…Recent pollen rain data generally come from moss polsters, which can be used as natural pollen traps that accumulate pollen for approximately 5-10 years [2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17]. Vegetation cover data have often been estimated with the phytosociological method proposed by Braun-Blanquet [18,19] for other purposes (e.g., [3,4,20,21]).…”

“…From the late 1970s, a number of studies have been undertaken in in Liguria (NW Italy), both in rural and urban areas, in an attempt to clarify the relationship between recent pollen deposition and vegetation (e.g., [8,[41][42][43][44][45][46]. The method used was a comparison of local pollen spectra, which were obtained through the analysis of natural traps (moss polsters) and quantification of the local vegetation cover obtained from phytosociological relevés [3,4].…”
