CAMERA TRAP MONITORING
So far, we have performed a total of four deterministic sessions in two reference areas for wildcats. Contrary to other deterministic camera trap monitoring sessions, the monitoring for the wildcat is financed over a multi-year project by a private foundation. The results of these sessions will not be published as KORA reports as for the lynx, but as scientific articles. The results and analyses will only be published here after the publication of the scientific articles. The camera trap pictures of wildcats from the deterministic sessions can be viewed in the KORA Monitoring Center.
REFERENCE AREAS
Northern Jura
100 km², 64 locations with 128 camera traps.
Most recent session: 24.02.2017–25.04.2017:
The scientific articles on this session have not been published yet. As soon as this is the case, the results will be presented here, too.
Earlier session: 25.02.2016–25.04.2016:
The camera traps at the 64 locations operated during 3,480 of the 3,840 potentially possible capture nights (100%). With 75 events at 28 locations, 13 wildcats were pictured from both sides (16 right flanks, 15 left flanks). Based on the individual identification of the wildcats, a density estimate was performed using the capture-recapture method. The capture-recapture estimate of the density (95% confidence interval) resulted in 26 (17–36) wildcats per 100 km² of suitable habitat. The data from the deterministic sessions were analysed using the R-package multimark. The integrated model offered a higher abundance and density estimate with higher precision than the analyses of individual flanks of the animals. This indicates that spatially-explicit capture methods as well as capture methods with “non-invasive” markings (e.g. the two flanks of a wildcat) offer an improvement for the monitoring of wildcats. The method is described in more detail in a scientific article.
Camera trap monitoring in the wildcat reference area Northern Jura. Reference area = grey grid. The circles with a point are camera trap locations where wildcats were pictured, empty circles are locations without wildcat pictures. Green and white dots indicate suitable and unsuitable habitat, respectively.
