In Italy, many research groups are aimed to establish and encourage the development of a national “Geobotanical Archive”, based on floristic and vegetation plots recorded relying upon the European phytosociological tradition (e.g Braun-Blanquet’s approach). Recently, several initiatives have been finalized to the fulfillment of a global vegetationplot database repository (i.e. EVA and GIVD). As part of this process here we present the “Georeferenced Vegetation Database - Sapienza University of Roma ” project (Global Index Vegetation-Plot Databases ID: EU-IT-011 registered since 2012-02-27, http://www.givd.info/ID/EU-IT-011). It is an ongoing vegetation-plots database, which collects relevés sampled in the whole Italian territory. Most of the data stored in the GVD-Sapienza are phytosociological relevés (72.67 %), the database contains also plots where data have been collected using other sampling methods (27.34 %). At present, the 21.917 vegetation plots encompassed in GVDSapienza come from multiple scientific sources: 15.430 plots from published contributions on plant-communities; 6.487 from unpublished field research. The time span of the database covers the period from 1935 to 2015, all are geographically referred with an accuracy scale. This archive was based on the need to go beyond a more consistent support to the coenological information and to explicitly enter the question of the requirement of a general, geographically exhaustive geobotanical survey for the country. Nowadays, beside GVD-Sapienza other databases at national scale (i.e. BVN-ISPRA and AnArchive/VEGItaly-SISV) are driven by single initiatives. However, in the next future, a federate coordinated database is needed to optimize common efforts toward an unified system at national scale. This report aims to present some basic statistical description, quality assessment and future perspectives of this growing georeferenced Italian vegetation database.

Abstract
In Italy, many research groups are aimed to establish and encourage the development of a national “Geobotanical Archive”, based on floristic and vegetation plots recorded relying upon the European phytosociological tradition (e.g Braun-Blanquet’s approach). Recently, several initiatives have been finalized to the fulfillment of a global vegetationplot database repository (i.e. EVA and GIVD). As part of this process here we present the “Georeferenced Vegetation Database - Sapienza University of Roma ” project (Global Index Vegetation-Plot Databases ID: EU-IT-011 registered since 2012-02-27, http://www.givd.info/ID/EU-IT-011). It is an ongoing vegetation-plots database, which collects relevés sampled in the whole Italian territory. Most of the data stored in the GVD-Sapienza are phytosociological relevés (72.67 %), the database contains also plots where data have been collected using other sampling methods (27.34 %). At present, the 21.917 vegetation plots encompassed in GVDSapienza come from multiple scientific sources: 15.430 plots from published contributions on plant-communities; 6.487 from unpublished field research. The time span of the database covers the period from 1935 to 2015, all are geographically referred with an accuracy scale. This archive was based on the need to go beyond a more consistent support to the coenological information and to explicitly enter the question of the requirement of a general, geographically exhaustive geobotanical survey for the country. Nowadays, beside GVD-Sapienza other databases at national scale (i.e. BVN-ISPRA and AnArchive/VEGItaly-SISV) are driven by single initiatives. However, in the next future, a federate coordinated database is needed to optimize common efforts toward an unified system at national scale. This report aims to present some basic statistical description, quality assessment and future perspectives of this growing georeferenced Italian vegetation database.
