Sažetak
In 40 years of their existence (Ellenberg, 1974), numerous criticism and approvals has been addressed to the Ellenberg’s indicator values. Through that period authors has adjusted and/or expanded them to floras from the Faroe Islands to Romania. Despite the fact, that even the expanded Ellenberg list (Ellenberg et al., 1992), covers less then 30% of it, an attempt to expand and adjust the indicator values for Croatian flora has never been done. In a meantime, such efforts were done for Hungary (Borhidi, 1995) and Italy (Pignatti et al., 2005), increasing the number of available indicator values to around 66% of Croatian flora. Out of this number, highest unique contribution was from Pignatti et al. (2005) ranging from 41.12% for light to 42.33% for soil reaction. Unique contribution of Ellenberg et al. (1992) and Borhidi (1995) lists were around 5% each, while overlap of available values from all three lists varied from 21.53% for temperature to 25.66% for light. For pairs of indicator lists, largest overlap were between Borhidi (1995) and Pignatti et al. (2005) ranging from 10.70% to 15.08% between environmental variables, while smallest was between Ellenberg et al. (1992) and Borhidi (1995) ranging from 4.82% to 6.18%. However, indicator values between lists were different for as much as 27.25% for continentality, followed by over 24% for soil reaction and moisture, 22.2% and 19.43% for temperature and light respectively, while difference for salinity was observed in just 4.86%. In case where differences between three lists of indicator vaslues at level of just one value were neglected, the biggest discrepancy remains for continentality (15.16%), followed by soil reaction and moisture (12.56% and 11.31% respectively). Difference, equal to or bigger than two, for temperature was present in 7.04% and 6.23% for light, while 1.42% for salinity. All these differences, with still existing lack of data for 1/3 of Croatian flora, imply on necessity of thorough analyses of Croatian flora with respect to the Ellenberg’s indicator values. This should include all available floristic and vegetation data that will enable calculation of adjusted and/or expanded list of indicator values, combining different appropriate approaches (e.g. weighted average values, HOF models, etc.).
