[6] NBMP data from selected species are used to produce one of the annual UK Biodiversity Indicators, high-level measures which are used to report on progress towards meeting goals and targets for the conservation of biological diversity.

[7] In 2009, as part of the National Bat Monitoring Programme, BCT began the first systematic UK-wide survey of Nathusius’ pipistrelles in order to improve knowledge of the distribution of this species.

Although data gained from the survey are still quite limited, there are indications that Nathusius' pipistrelle may be relatively widespread across lakes in some regions in the autumn.

The BCT email bulletin is sent out every two months with current news stories relating to the organisation and general bat conservation.

It features bat-themed activities, games, stories, competitions and curriculum guidance for teachers and is also published three times a year.

The conference programme includes talks, workshops and the presentation of both the Vincent Weir and Pete Guest Awards.

The award is presented annually to a student at a UK-based institution who has made a significant contribution to research on the conservation biology of bats.
