A regular quarterly inspection was carried out in Barać Caves to record microclimatic data, verify the proper operation of monitoring instruments, and perform necessary adjustments and maintenance. During the inspection, it was observed that the Baraćevac spring had a high water level and an abundant flow, which prevented access to the submerged probes. Consequently, maintenance activities at that location will be postponed until hydrological conditions permit safe and effective work.
Overall, the monitoring instruments continue to operate reliably, providing valuable data for ongoing analysis. However, it was noted that one Hobo data logger has ceased functioning. Given the challenging accessibility of the site where it is located, its replacement will be carried out during the next scheduled visit when conditions allow.
Following the winter ventilation period, particularly in the Upper Cave, an increase in CO₂ concentration has been detected. This rise coincides with the seasonal intensification of biological activity in the soil and the onset of the tourist season. Control measurements recorded CO₂ concentrations ranging between 2000 and 4000 ppm. The Lower Cave remains better ventilated compared to the Upper Cave, which is consistent with previous observations of airflow dynamics within the cave system.
The collected data will continue to support the evaluation of cave microclimate trends and inform future management and conservation strategies.
