Sažetak
Holm oak (Quercus ilex L.) is the main indigenous forest species of eumediterranean area in Croatia. Holm oak can be found in all forms of breeding and degradation stages, and maquis and garrigue are most found degradation stages of holm oak forests. Forest ecosystems are influenced by numerous local meteorological and climatological conditions. Numerous ecological processes are closely related to weather conditions, and correct data on forest climate are needed to study them. Disorganized and uncontrolled cuttings of high forest stands and their conversion into degradation stages, changes microclimate conditions of certain stand. Microclimate researches were done in the area of Island Mljet. Forest microclimate depends on the local climate, relief, soil and forest stand structure. Measurements were done in the holm oak forest and in the degradation stages of maquis and gariggue. During one year was measured air temperature and soil temperature (°C), relative air humidity (%), specific air humidity (%), and volumetric soil water content (%). Average temperatures of air and soil were highest in the gariggue stage, and the least in the maquis stage. The highest absolute maximum air temperature was measured in the gariggue stage, and the highest minimal in the maquis stage. Average relative air humidity had the highest value in the high forest stand. The values of volumetric soil water content were the lowest in gariggue, and the highest in maquis. The highest variations of microclimate elements were measured in degradation stages of holm oak. Microclimate conditions in degradation stages of holm oak are less favourable for growth and development in relation to microclimate conditions in high forest stand. Correlations of microclimate elements in studied forest stand and degraded stages were positive, significant and high to complete. Analysis of these data can be used to better understand ecological conditions of forest habitats.
