Abstract

Domogled-Cerna Valey is a protected area characterized by a climate with sub-Mediterranean influences. The lithological and pedological substrate, as well as the specific climate, have given a xerophilic character to the area's flora and vegetation. But even for the vegetation adapted to these conditions, climate changes with very long periods of drought have created significant physiological imbalances, which in the longer term (if those conditions are maintained) will cause changes in the structure of the habitats.
The determinations were made in Tesna-Valley Natural Reserve, and the plants studied were Genista tinctoria, Cerastium banaticum, Dianthus petraeus, Hypericum rochelii. The very low values of the photosynthesis intensities determined in 2024, low biomass accumulations, and the decrease in the growth rate, affecting also the flowering and fruiting processes. If these conditions continue to manifest in the coming years, it is possible that the number of individuals in the populations will change significantly.
