Systematic phenological data have been collected in Slovenia since 1951 by Evironmental Agency of the Republic of Slovenia, former Hydrometeorological institute of Slovenia. Nowadays, 36 phenological ...phases are studied by observing 64 different plants (41 non cultivated and 23 cultivated extended on varieties) at 61 stations in various Slovene regions and altitudes. Several areas that deal with phenological processes are delineated, like agriculture, forestry, medical meteorology, biodiversity, tourism, climate change studies and plant development modelling. Phenological records were used as data base for numerous investigations in past two decades.
The new Act on Forest Reproductive Material, which was adopted in June 2002, in accordance with the EU Directive on the marketing of forest reproductive material, demands the demarcation of regions ...of provenance for the production of forest reproductive material. In this paper, the proposal for demarcation of ecological regions and sub-regions, which are the basis for defining the proposed regions of provenance, is presented. The borders of ecological regions are transitional or mosaic. For rationalisation of the delimitation of the regions of provenance in the field and easier control of usage, the borders of the regions of provenance are, as much as possible, adapted to the management and administrative borders, which are marked in the field. The basis for delimitation of seven regions of provenance, divided into 4 altitudinal zones, is presented.
