“…In this paper, the vegetation history of four coastal sites by the Mar Ligure Sea is reconstructed through pollen analysis of ten cores and an attempt to trace the Holocene landscape history of the NW Italian coasts is made by delineating typological and chronological correlations between the various pollen sequences. Palynological research on sedimentary series of the NW Italian coasts has been sporadically undertaken in the past (Galletti Fancelli, 1971, 1979Montanari et al, 1998;Arobba et al, 2001;Mariotti-Lippi et al, 2007a, b). Correlating this data with new research could allow a broader picture of the history of these coasts and of the man-environment relationship to be revealed.…”

Cores from four coastal plains of the Mar Ligure Sea in N Tuscany and E Liguria (Italy) were investigated by means of pollen analysis to delineate the Holocene landscape history of the NW Italian coasts. In the first half of the Holocene ( c. 9800—7000 cal. yr BP) all four sites show elevated percentages of Abies pollen which suggest the local presence of fir woods (with Ulmus, Tilia, etc.). In the second half of the Holocene (from 7000 cal. yr BP), Abies becomes locally extinct along the coasts leaving space for the development of mosaic landscapes formed by open meso-thermophilous woods (with deciduous Quercus, Alnus , Corylus) and Mediterranean maquis (with Erica cf. arborea). The new data represent a significant contribution to the reconstruction of the landscape history of the NW Italian coasts and of the history of fir in Italy. Along all examined cores discontinuous pollen records show that initially the coastal areas were characterized by retrodunal wetlands; after c. 6000 cal. yr BP only the larger plains in N Tuscany remained extensively damp while the smaller plains in E Liguria were buried (and/or drained). Thus, these buried deposits of ‘fossil’ coastal wetlands proved to be only partially useful for high-resolution environmental archaeology and history studies. Nonetheless they are unique traces of ecosystems that provided important local economic resources for millennia and formed elements of the coastal cultural landscapes which have almost totally disappeared today.

“…The sequences recorded in the area in the previous years, up to a depth of 33 m below road level, already showed the occurrence of coarse sediments in the upper levels and silty-clayey horizons in the lower part, often rich in organic matter. These data point to an alluvial depositional environment and marshy areas, related to the mouth of the Bisagno (Montanari et al, 1997(Montanari et al, , 2014.…”

“…This work has been undertaken in the last 50 years and has allowed the University of Genoa to carry out archaeological and bioarchaeological investigations. The data recovered by multidisciplinary studies on the first anthropization of the urban area of Genoa turned out to be essential for the reconstruction of the changes occurred in the plain of Bisagno during the middle Holocene (Arobba et al, 2016(Arobba et al, , 2017aBonci et al, 2014;Montanari et al, 1997). The study has allowed us to identify the presence of currently locally extinct species and to recognize new non-pollen palynomorph (NPP) types, as well as to reveal the earliest traces of human presence in the area, in relation to agricultural practices documented by cereal macro-remains.…”

The article presents the results of a multi-proxy study investigating an alluvial deposit located in the coastal plain of Genoa (Liguria, Northwest Italy). A very deep core was sampled from 15 to 25 m below ground level to analyse sedimentological properties, pollen assemblages, non-pollen palynomorphs, plant macrofossils and micro-charcoal. The deposit, spanning from the second half of the 5th Millennium to the end of the 7th Millennium cal. BC, was characterized by an alternation of silty and peaty layers, and proved to be rich in plant remains. Pollen data allowed the confirmation of a gradual increase in Fagus sylvatica to the detriment of Abies alba during the mid-Holocene of the region, and showed the presence of brackish lagoons, as well as the progressively stronger incidence of anthropogenic taxa, indicating the use of the plain for agricultural purposes. The study of non-pollen palynomorphs led to the taxonomic identification of some previously unidentified types, and pointed to the occurrence of marshy environments, which were probably grazed on by domestic herbivores. Macrofossil analysis provided the first record of Triticum new glume wheat type in Liguria. Moreover, the finding of a grain of Triticum dicoccum dated to the second half of the 6th Millennium cal. BC allowed us to pre-date by seven centuries the agriculture in the region. To date, this represents the oldest evidence of human activity in the urban area of Genoa.

“…BP; Accorsi et al, 1999;Vescovi et al, 2010). In general, its past diffusion was decidedly broader than may now be found in Emilia Romagna as indeed across the rest of the Italian Peninsula (e.g., Montanari et al, 1997;Mariotti Lippi et al, 2007;Di Rita et al, 2011;Joannin et al, 2012). Abies decline was evident in the mid-Holocene, possibly due to the loosely coupled effect of increasing dryness and human pressure from the Neolithic onwards.…”
