The most common approaches for summer bat monitoring in Europe are acoustic recording and captures from roosts. However, these methods provide only fragmentary data about species richness and abundance, without information about population structure. In order to obtain complex information about sex and age structure, in 2008 we developed method wich implies mist netting for a primary inventory and following monitoring of bat fauna in forests. In short period of time (20 days) we revealed all bat species known for the territory of the National Park \u201cHomilsha forests\u201d (Kharkiv region, Ukraine).The method described here was sucesfully used by our team in inventory bat fauna in Kharkiv region, Ivano-Frankivsk region, Chornobyl Exclusion Zone (Ukraine), Nature reserve "Brynsky forest", National park "Smolensk lakeland", Oksky Nature reserve, Voronezh Nature Resrve (Russia). Compare to bat detectors mist nets are cheaper technique for bat surveys, but need more time input.
