During the 2014 field season the eradication and monitoring activities were carried out without any deviation from the project schedule. According to the more optimistic predictions provided in the eradication plan, it is possible that the efforts in the lakes Djouan and Nero (the smaller lakes) were successful in eradicating Salvelinus fontinalis. However it would be necessary to wait for the next field season to get some confirmatory data. In the lakes Dres and Leynir, fish captures continued also in the 2014, mainly affecting young, small brook trout, which, according to the eradication plan, could not be caught during 2013. The capture rates drop down to very low levels in both the lakes and it would be necessary to wait for the next field season to see if the eradication process will be completed within the scheduled time (3 years).
The resilience process in the treated lakes was monitored by measuring or sampling (1) the chemical and physical properties of lakes’ water, (2) the chlorophyll-a concentration, (3) the zooplankton community, (4) the community of littoral macroinvertebrates, (5) the biomass exchange between terrestrial and aquatic habitats (in terms of emergent and sinking insects) and (6) the reproductive success of Rana temporaria in the treated lakes and in a set of control lakes (with and without fish). The ecological resilience was yet clearly visible for some of the measured variables. In general there are many observational evidences of the ecological resilience. However a quantitative analysis of the ecological resilience has yet to be done.
Detailed information and monitoring data on the project schedule are provided in the Report V2 and related appendices, in Dowload section
