  1. Thin trees within forests

    At Piedmont National Wildlife Refuge, Georgia, USA (Powell et al. 2000), a replicated controlled study in 1993-1996 found no impact of thinning and prescribed burning on wood thrushes Hylocichla mustelina. This study is discussed in detail in ‘Use prescribed burning’.

     

  2. Use prescribed burning on pine forests

    At Piedmont National Wildlife Refuge, Georgia, USA, a four-year replicated controlled study found no evidence that winter burning and tree thinning (management primarily to improve red-cockaded woodpecker habitat) negatively affected wood thrushes Hylocichla mustelina in loblolly pine-dominated forest (Powell et al. 2000). Thrush density and adult or juvenile survival during the breeding season did not vary between compartments subject to thinning and prescribed burning and unmanaged ones. Overall, thrush numbers increased on treatment compartments (0.91-0.97 birds present before vs. 0.98-1.05 after management), and declined slightly in controls (0.98-1.05 vs. 0.87-0.92). Plots were surveyed eight times in 1993 and sixteen times a year in 1995-1996.
