First results on mycocoenological and phytocoenological characteristics of Austrian pine (Pinus nigra) stands in Istria, Croatia

Mycological and plant characteristics of Austrian pine (Pinus nigra Arnold) stands in Istria, Croatia were surveyed. Mycocoenological description was based on fruit body and species number. Fungi samples were collected on three different permanent research plots of 400 m2 each, for three consecutive years (2011/2012/2013) from week 36 to week 50 every fortnight. Plots showed distinct differences in fungal species and fruit body number. High variation of fruit bodies for the single year was observed. Stands characteristics were also observed in order to define potential natural vegetation status of pine cultures. Phytocoenological survey was performed during April and June of 2014. at all plots. Three soil types recorder were Eutric Cambisol on flysch bedrock, Terra Rossa and Black soil on limestone (Calcomelanosol). Floristic composition of pine stands differed among the plots showing mixtures between eumediterranean/submediterranean and submediterranean/ mountain vegetation regions. Together with plants, different fungi species were found as good indicators of Austrian pine habitat characteristics. Long term survey is needed to better understand the ecology and role of certain fungal species that characterize different Austrian pine habitats.
