Standards for the monitoring of the Central European wolf population in Germany and Poland

Print Friendly, PDF & Email


Germany and Poland share a joint wolf population ‐ the Central European population. For a joint assessment of the status of transboundary populations, the underlying data must be comparable. In 2012, the members of the Polish‐German wolf working group decided to commission the development of joint monitoring standards as a prerequisite to allow a robust population‐level evaluation of population size, area of occurrence and their respective trends.

The proposed joint German‐Polish monitoring standards presented here are based on the SCALP criteria, which classify wolf observations according to their verifiability. Population size and area of occurrence assessments are based on hard facts (C1) and confirmed observations (C2) only. There are still minor differences in data evaluation between Germany and Poland, which we aim to overcome in coming years as we gain experience applying the criteria. Wolf scientists from both countries should meet once a year to report national monitoring results, jointly determine the status of possibly transboundary territories and estimate the effect of deviations that still exist in data evaluation.
The output of these meetings should be an annual status report on the Central European wolf population, with joint assessment of population size and a transboundary distribution map. The meetings should also be used to review and refine the standards, taking into account the expected increase in population size and concomitant increase in range. It is recommended that other countries sharing the same population, like the Czech Republic and in future perhaps Denmark and the Netherlands, too, should join these meetings and adopt the same monitoring standards. <<<Read Full Report>>>
