Woodland management for birds: Priority species
A decline in productivity due to the timing of migration possibly becoming out of phase with peak invertebrate availability in deciduous woodland (Fuller et al. 2005; Hüppop and Winkel
Reduction or cessation of grazing pressure in some woodlands resulting in an increase in shrub and field layer vegetation, leading to a reduction in horizontal visibility.
Insufficient availability of nest sites, possibly due to competition with tits where tree hole density is low.
Increase the extent or improve the quality of nest sites
Manage for deadwood to ensure
availability of tree-hole nest sites.
Provide nestboxes in woodlands where natural nest sites maybe scarce (see Nestboxes).
Increase the extent or improve the quality of feeding habitat
Create and maintain an open under- storey, sparse shrub layer and a low field layer to increase insect abundance and accessibility, eg by managing grazing.
Maintain open field and shrub layers, eg restricting bramble and bracken development by managing grazing appropriately. This needs to be balanced with the encouragement of future canopy trees through retaining or protecting saplings where necessary.
Increase the abundance of deadwood through ring-barking or injecting herbicides into younger crowding timber to encourage populations of parasitic wasps and flies as a food source.
