Bird (from the BBS) and butterfly (from the UKBMS) abundance data used in the paper. Bird species names are given as BTO species codes. Sites where no study species were recorded have "NoTargetBirdRecorded" or "NoTargetButterflyRecorded" in the species column, and no value in the count column. NOTE - because this dataset has been processed as described in the paper, we strongly recommend researchers wishing to use BBS and UKBMS data in their own research to obtain data from the BTO (https://www.bto.org/research-data-services/data-services/data-request-system) and the UKBMS (http://www.ukbms.org/Obtaining.aspx) rather than use this file
