BTO publishes various reports, from those covering the annual results of core surveys, through scientific studies, and on to those produced in partnership with other organisations. Many of these are published as BTO Research Reports. You can access all of our reports from here, though note that we are currently updating the reports section, working backwards through time to bring all of the report pages into a consistent format. You can read our Annual Report and Accounts in the Governance section.

Exclusion of deer affects responses of birds to woodland regeneration in winter and summer
Author: Holt, C.A., Fuller, R.J. & Dolman, P.M.
Published: 2014
Native and non-native deer populations are increasing in temperate woodlands across Europe. Previous work by the BTO found that these changes are associated with declines in some breeding bird populations, and suggested this is due to modification of the woodland understorey through browsing (consumption of vegetation by herbivorous deer). Now a new study by the BTO and the University of East Anglia has demonstrated effects of deer activity on birds outside the breeding season.
