Project description


Spotlight surveys of brown hares


The continuous survey of wild animal populations and conditions in their habitat constitutes a prerequisite for scientifically sound statements on their abundance and population development. Population dynamics and ecologic interconnections, alongside environmental factors that influence populations, should be described for the ecosystem of the "cultural landscape." IWFo has worked in this field for many years to create a solid data and knowledge base for wildlife management, providing, among other things, directives for hunting practice as well as reviewing and documenting sustainable use of wild animal populations.

Comprehensive wildlife surveys to gather information on occurrence and population sizes of several domestic wild animal species (hares, partridges, foxes, corvids, geese, etc.) and several neozoes (e.g., raccoons, raccoon dogs, Canada geese) have been performed since 1991 on the basis of annual population estimates by the owners of more than 8,000 hunting grounds (corresponding to approximately 80% of the surface area of Lower Saxony).

Established wildlife biology counting methods are used to assess the population estimates resulting from the wildlife surveys (e.g., brown hares, partridges). Additional investigations of population ecology expand knowledge on different wildlife species and environmental factors influencing them.

The most recent figures from the wildlife surveys are available in the annual "Landesjagdbericht" (state hunting report).
