NDFF Atlas of the dutch bats 1997

The Bat Atlas Project (VAP) has the following aims: Carrying out a systematic survey of the bats occurring in the Netherlands in their summer biotope. Gaining insight about the bats use of the landscape. Attracting more attention for bats and thereby improving their conservation status. The first aim of the VAP has become more comprehensive. Over time, systematic surveys of bats in their winter habitats were strongly encouraged. The scale of an hour plot or atlas plot (a grid cell of 5 square kilometres) was chosen to carry out a systematic survey. About 94 percent of observations have been made using a bat detector. In addition, the following methods have been used: Catching bats with nets Examining hibernation sites in buildings (mostly church attics) Photographing bats Surveying bat boxes Attracting publicity for bats. The observations were made from 1986 to 1993. Various experts check observations of rare species, observations of the Myotis species, which can easily be confused, and observations of a common species previously unknown in a particular area.
