A general view of the quarry - October.
In 2003 (thanks to the
help of Palev Vlaschenko, Sergey Chernyh and Anton Biatov) a deep
crevice in a wall of the abandoned open quarry with bat droppings
was occasionally found (Kharkov Province, Izumsky district). In
the first night more than 120 bat individuals of 6 species were
captured, including new species for the region.
The crevice where bats hibernate and stay during autumn migration.
The open quarry is located at the the right high bank of
the Seversky Donets River not far from the place of confluence of
the Donets with Bereka river. From the high wall of the quarry there
is a beautiful view at the left bank of the S. Donets River with borderless
forests. Beside the beautiful view the open pit is the Klondike for
bat researchers. The quarry is a place through which bats follow during
autumn migration to hibernacula. Hundreds of bats stay for hibernation
in the crevice of the quarry.
On the base of results
of 2003-2005 the working hypothesis was advanced that there could
be others quarries or natural denudations with bat-crevices in the
region. The investigation was supported by Scholarship Program of
The Bat Conservation International; the project name “Key Role of
Bat Hibernation Sites in Deep Rock Crevices for Their Conservation
on a Territory without Natural Caves, North-eastern Ukraine”.
During the project (2006-2007) we had examined a
big territory in the Kharkov Province (near 1000km2). We’d spent
more than 60 field days and footed over more than 200 km. Unfortunately,
we did not find any other open pits inhabited by bats or natural
denudation with bat-crevices. Thus, we concentrated our research
at already known quarry near Zavody village in Izum district. During
the project we had 19 field days catching bats in the open quarry.
Then 543 bat individuals of 10 species were caught.

The main tasks are:
- to study phenology of bat migration,
- to study sex and age structure of the bat assemblage.
