Dinaric karst poljes and their importance for mycobiota

Karst as a geological phenomenon and karst poljes as the largest depressions in the Dinaric Alps represent one of the most important and most diverse relief units globally. The diversity of karst poljes in the Dinaric Alps is one of the most significant worldwide and one of the most heterogeneous, too. In this study, by using the most relevant variables and delimitation criteria, all recognized Dinaric karst poljes were divided and classified into 30 well differentiated groups and organized in nine main biogeographical regions. During the process of classifying the Dinaric karst poljes, for some of the most important parameters recognizable patterns were defined or established for each group. The mycobiota of 10 Dinaric karst poljes classified into six groups have been intensively studied in Bosnia and Herzegovina and Croatia during various research sessions. All results were evaluated by using standardized variables and a corresponding binary grading scale in order to classify poljes according to their importance for mycobiota. Based on the “cumulative ecological score” (CES), the ratio of the CES/number of all recorded species and the CES/number of research days ratio, the mycologically most important karst poljes were identified. A brief description of specific habitat types of top evaluated poljes is given together with recommendations for the implementation of proper conservation measures in these areas. Several rare and very vulnerable species of ascomycetes, like Mollisia uda, Patinella hyalophaea, Podostroma leucopus, Scutellinia peloponnesiaca and Lamprospora leptodictya, were recorded in the investigated poljes. Some of the species which were found during the present study, represent the only known records in the Dinaric Alps and their conservation status has never been assessed before. Recommendations for the protection of these species, based on IUCN criteria, are presented.
