The new Forest Atlas of Umbria Region is a work in progress, funded by the Forest Service of Umbria Regional Office, aimed at developing an integrated approach by crossing the basic methodologies of forest science and phytosociology. Its object is to point out similarity and differences between two distinct, sometimes divergent approaches to forest vegetation. A phytosociologic study, including a bioclimatic and geologic characterization, was carried out in 6 randomly selected sample areas, each corresponding to 1/16 of a mesh of the European grid (scale 1:10.000, about 5x4,5 km2), all located in Central Italy. The same areas were separately investigated with regard to the forestry management, considering dominant species, structure, physiognomy, stage of growth, coppice cycle length. On account of their different ecological conditions and management, the areas offer a wide survey on the forest diversity of Central Apennine and Pre-Apennine. Thematic, geographically referred maps were produced and their data confronted, in order to find out if and how the different management affects the floristic composition and the vegetational type. For each pointed out forest type, an illustrative record, including photos and a floristic, vegetational, ecological and sylvicultural characterization, has been produced and will be part of the Atlas together with the maps. The investigated vegetational types have been referred to the following alliances and suballiances: Laburno-Ostryenion carpinifoliae (Ubaldi 1995) Blasi et al. 2004, Lauro-Quercenion pubescentis Ubaldi (1988) 1995, Teucrio-Quercenion cerris Blasi et al. 2004, Cardamino-Fagenion sylvaticae Biondi et al. 2002, Doronico-Fagenion sylvaticae (Ubaldi et al. ex Ubaldi 1995) Di Pietro et al. 2004, Pulmonario-Carpinenion betuli Biondi et al. 2002, Fraxino-Quercion ilicis Biondi et al. 2003, Alnenion glutinosoicanae Oberd. 1953. Through this experimental development of an integrated sylvicultural/phytosociological protocol for the forest vegetation survey, we could also evaluate costs, duration and benefits of such a project, when extended to the whole regional territory.

Abstract
The new Forest Atlas of Umbria Region is a work in progress, funded by the Forest Service of Umbria Regional Office, aimed at developing an integrated approach by crossing the basic methodologies of forest science and phytosociology. Its object is to point out similarity and differences between two distinct, sometimes divergent approaches to forest vegetation. A phytosociologic study, including a bioclimatic and geologic characterization, was carried out in 6 randomly selected sample areas, each corresponding to 1/16 of a mesh of the European grid (scale 1:10.000, about 5x4,5 km2), all located in Central Italy. The same areas were separately investigated with regard to the forestry management, considering dominant species, structure, physiognomy, stage of growth, coppice cycle length. On account of their different ecological conditions and management, the areas offer a wide survey on the forest diversity of Central Apennine and Pre-Apennine. Thematic, geographically referred maps were produced and their data confronted, in order to find out if and how the different management affects the floristic composition and the vegetational type. For each pointed out forest type, an illustrative record, including photos and a floristic, vegetational, ecological and sylvicultural characterization, has been produced and will be part of the Atlas together with the maps. The investigated vegetational types have been referred to the following alliances and suballiances: Laburno-Ostryenion carpinifoliae (Ubaldi 1995) Blasi et al. 2004, Lauro-Quercenion pubescentis Ubaldi (1988) 1995, Teucrio-Quercenion cerris Blasi et al. 2004, Cardamino-Fagenion sylvaticae Biondi et al. 2002, Doronico-Fagenion sylvaticae (Ubaldi et al. ex Ubaldi 1995) Di Pietro et al. 2004, Pulmonario-Carpinenion betuli Biondi et al. 2002, Fraxino-Quercion ilicis Biondi et al. 2003, Alnenion glutinosoicanae Oberd. 1953.
