Description

This dataset from the National Bat Monitoring Programme, has national (UK) abundance indices for eight bat species from 1998-2014. For more information see Barlow et al (2015). There are 136 lines of data, seven of which are NA, reflecting late entry into the time series for two species (Natterer's and Brown Long-eared bats).
