Abstract

Background and Purpose: Biological invasions are causing serious
problems in the environment, often resulting in significant modifications of the landscape structure and ecosystem functioning. J.P. Grime’s theory on CSR strategies of plants indicate whether plant species is a good competitor, adapted to disturbance or to limited resources. The goal of this study was to find which CSR strategy (if any) prevails among invasive plants in Croatia.

Materials and Methods: Data on CSR strategies were not available,
or not consistent, for all invasive plants in Croatia, hence we have allocated CSR strategies to 15 invasive taxa, using the methodology based on several plant traits, which resulted in assignment of CSR type to 57 invasive plants. Distributional records of those 57 taxa in Croatia from the Flora Croatica Database were used to analyse the occurrence of invasive plants among three biogeographical regions (Alpine, Continental and Mediterranean).

Results and Conclusions: In total, 10 CSR types were found among
the invasive plants of Croatia, mostly CR-strategists, followed by C-strategists and R-strategists. The largest proportion of R-strategists was found in the Mediterranean region, while the largest proportion of C-strategists was found in the Alpine region. Out of the three main strategies, competitive ability and ruderality were found to be frequently present within the Croatian
invasive flora, while stress tolerance was almost absent.
