Each of the UK countries has ambitious targets for forest expansion which provide both opportunities and threats for different birds. BTO’s research includes identifying influences of different silvicultural systems and restructuring within forests and also the opportunities and constraints associated with forest expansion. Studies sites include a range of forest sizes and ages small farm woodlands through to extensive plantations and newly planted or regenerating woodlands through to ancient stands.
Agri-environment effects on birds in Wales: Tir Gofal benefited woodland and hedgerow species
Breeding bird assemblages supported by developing upland shrub woodland are influenced by micro-climate and habitat structure

An efficient survey method for estimating populations of marsh tits Poecile palustris, a low-density woodland passerine
How can assemblage structure indices improve monitoring of change in bird communities using ongoing survey data?
English Farm Woodland Bird Survey
Help collect data on how birds have colonised woods planted in farmland.
Can volunteers’ data be used to monitor land cover change?
BTO scientists were keen to see if habitat data collected by volunteers for the Breeding Bird Survey (BBS) could contribute to understanding how habitats have changed. Over 2,500 BBS volunteers have...
Understanding the influence of habitat upon breeding Woodcock numbers in Britain
National BTO/GWCT Woodcock surveys undertaken in 2003 and 2013 provided data from 807 and 823 randomly selected 1 km squares, respectively. Woodcock counts were compared with a range of landscape-...
Implications of transformation to irregular silviculture for woodland birds: A stand wise comparison in an English broadleaf woodland
Woodland birds in Britain have undergone significant long term declines since the late 1960s, associated in particular with changes in woodland structure in general, and loss of early successional...
Take part in BBS - counting for conservation
The Breeding Bird Survey is the main scheme for monitoring the population changes of the UK’s common and widespread breeding birds. The survey involves two early-morning spring visits ...
Help monitor Woodcock in Britain and Ireland
We urgently need to monitor changes in breeding Woodcock numbers, given the recent population decline.
