“…This suggests a climatic improvement, especially regarding precipitation, and late glacial forest development in northwestern Iberia seems to have taken place during this time (Penalba et al, 1997;Ruiz Zapata et al, 2002;Munoz Sobrino et al, 2004, 2007Jalut et al, 2010). This phase could therefore be correlated with the late glacial interstadial GI-1 (Bolling-Allerad, 14,700-12,650calyrBP; Bjorcketal., 1998), which is characterized by a significant rise in temperature and precipitation (Clark et al, 2012).…”

We reconstructed vegetation responses to climate oscillations, fire and human activities since the last glacial maximum in inland NW Iberia, where previous paleoecological research is scarce. Extremely sparse and open vegetation composed of steppic grasslands and heathlands with scattered pioneer trees suggests very cold and dry conditions during the Oldest Dryas, unsuitable for tree survival in the surroundings of the study site. Slight woodland expansion during the Bolling/Allerod was interrupted by the Younger Dryas cooling. Pinewoods dominated for most of the early Holocene, when a marked increase in fire activity occurred. Deciduous trees expanded later reaching their maximum representation during the mid-Holocene. Enhanced fire activity and the presence of coprophilous fungi around 6400-6000 cal yr BP suggest an early human occupation around the site. However, extensive deforestation only started at 4500 calyr BP, when fire was used to clear the tree canopy. Final replacement of woodlands with heathlands, grasslands and cereal crops occurred from 2700 cal yr BP onwards due to land-use intensification. Our paleoecological record can help efforts aimed at restoring the natural vegetation by indicating which communities were dominant at the onset of heavy human impact, thus promoting the recovery of currently rare oak and alder stands.

We present the Holocene sequence from Lago Enol (43°16′ N, 4°59′ W, 1070 m a.s.l.), Cantabrian Mountains, northern Spain. A multiproxy analysis provided comprehensive information about regional humidity and temperature changes. The analysis included sedimentological descriptions, physical properties, carbon and carbonate content, mineralogy and geochemical composition together with biological proxies including diatom and ostracod assemblages. A detailed pollen study enabled reconstruction of variations in vegetation cover, which were interpreted in the context of climate changes and human impact. Four distinct stages were recognized for the last 13,500 years: (i) a cold and dry episode that includes the Younger Dryas event (13,500−11,600 cal. yr BP);(ii) a humid and warmer period characterizing the onset of the Holocene (11,600−8700 1 cal. yr BP); (iii) a tendency toward a drier climate during the Middle Holocene (8700−4650 cal. yr BP); and (iv) a return to humid conditions following landscape modification by human activity (pastoral activities, deforestation) in the Late Holocene (4650−2200 cal. yr BP). Superimposed on relatively stable landscape conditions (e.g. maintenance of well established forests), the typical environmental variability of the southern European region is observed at this site.

“…hasta nuestros días) (Vernet y Thiébault 1987) indica que la influencia humana sobre la vegetación varía según las regiones, siendo máxima en los territorios del actual piso termomediterráneo; por el contrario, está poco marcada en las zonas montaño-sas que rodean la región mediterránea. En este sentido, los datos arqueobotánicos de Pinhovelo, en el Noreste de Portugal, señalan la pervivencia de bosques de Quercus caducifolios (Tereso 2009), aunque la predominancia de los cereales y los datos políni-cos del noroeste de la Península Ibérica Rodríguez 1997;Gómez-Orellana 2004;Muñoz et al 2005) indican que los alrededores del asentamiento habrían estado fuertemente ocupados en época romana.…”

RESUMENSe presentan los resultados obtenidos por la antracología y la carpología en la villa romana de Gabia, que nos dan un importante conocimiento sobre la explotación del medio y del uso de los recursos vegetales utilizados con diversas finalidades. Estos resultados confirman la existencia de un paisaje fuertemente antropizado, con una vegetación relativamente abierta donde tienen una gran importancia las especies arbustivas y de matorral, quedando sólo la encina y el pino carrasco como representantes del estrato arbóreo. Los cultivos predominarían en el entorno, siendo los cereales, con el trigo desnudo y la cebada vestida, los que ocuparían parte de las tierras ganadas al bosque, desarrollándose también leguminosas como garbanzos, lentejas, guijas, guisantes y habas. El combustible para los hogares provenía tanto de leña recogida en el bosque, como de los deshechos de las podas de los árboles cultivados. Para la construcción de postes y vigas se recurre a árboles de gran porte, que pueden ofrecer leños rectos y largos, caso de los pinos y el olmo y ramas de gran resistencia como son el nogal y la encina; mientras que para la construcción de los techos se utilizan especies arbustivas: enebros, leguminosas, retama y romero SUMMARY Anthracological and carpological findings are presented for the Roman villa of Gabia, which gives us important knowledge concerning the exploitation of the environment and the diverse use of plant resources. The results confirm the existence of a strongly humanized landscape, with relatively open vegetation where shrubby and thicket species have great importance, with the Holm oak and the Aleppo pine being the representatives of the tree stratum. Crops would predominate the setting, where cereals, i.e. barley and glumeless wheat, occupying land reclaimed from the forest, while legumes such as chick-peas, lentils, grass peas, sweet peas, and fava beans were also cultivated. The fuel for fireplaces came from wood gathered from the forest as well as the remains from pruning cultivated trees. For the construction of posts and beams, large trees were used, these offering long, straight logs in the case of pines and elms, and branches of great strength such as walnut and Holm oak. For the construction of roofs, shrub species were used: common junipers, legumes, broom, and rosemary.
