Background information and definitions
If large amounts of wood are available, then it may be possible to deliver the benefits of having woody debris in forests without having to damage the trees themselves.
Supporting evidence from individual studies
In Gunbower State Forest, Victoria, Australia, a randomised, replicated, controlled study (MacNally et al. 2002) found that brown treecreeper Climacteris picumnus numbers were consistently higher in plots of red river gum Eucalyptus camaldulensis forest with coarse woody debris (aged fallen wood >10 cm in diameter) added to them, compared to control plots (1.5-2.2 birds/ha in plots with 40-80 Mg/ha or more of debris added vs. 0.6 and 0.4 birds/ha for 20 Mg/ha and no debris added treatments). Birds appeared not to discriminate between logs and tree crowns.Study and other actions tested
