Evidence based and adaptive management in conservation needs decision making based on valid, objective and reliable data. Inventories as systematic surveys on state and development of species and habitats have therefore a key function for qualified conservation and restoration programs and impact assessments.

In reality decision-relevant data for conservation are often not available, uncertain, not spatially explicit or not up-to-date. Therefore decision making happens usually under high risk and with uncertain effects and outcomes. Because of this there are good reasons to focus on the triangle of strategy building, inventories and decision making to improve the effectivity and efficiency of management in conservation.

In my 2nd position at the Northwest German Forest Research Institute (NW-FVA) we are developing inventory designs for monitoring of forest composition, forest structure and biodiversity of woodland under natural development (10 % of area of the Lower Saxony state owned forests).


Of more than 90 Million hectares of beech forests in Europe there are only 0,05 % undisturbed by deforestation, agriculture and forestry. The last ontouched remnants and small fragments of natural beech forests are found in the Carpathians and on the Balkan. Deforestation, grazing of domestic animals, shifting tree species composition to conifer rich stands, limiting tree and stand age to young and productive stages and changing wildlife by hunting caused heavy changes of compositon, structure and habitat quality on close to 100 % of beech forest area in Europe.

Decision making in conservation depends often on assessments of results from surveys and the top end of the scale should be derived from data out of low or not disturbed reference sites. Therefore it is important to study species compostion and habitat qualities in natural forests and to document the effects of human induced disturbances on these in a gradient of growing intensity from natural to highly commercial forests. My focus is on old growth dependent species and among this on forestry-sensitive vertebrates with high area requirement which can be used as target and umbrella species.


The use of detection dogs offers good opportunities to improve species surveys for research, inventories and monitoring. A lot of species conservation related questions can be answered in a more effective and more efficient way as well as with lower impact on individuals compared with other methods.

The use of detection dogs in conservation settings is more common and developed in the United States, Canada, New Zeeland and Australia and is still quite rare in Eurasia. Despite from the need of method-transfer to Europe there is a general demand for further development and optimization of suitable training and application procedures. Especially important is to analyze how general and environmental conditions coincide with the performance of detection dog based survey methods. Own detection dogs for conservation are trained since 2006. More about dectection dogs für species surveys and monitoring in research and management see CDK9s.
