  1. Clear or open patches in forests

    A replicated controlled before-and-after study in oak and hickory Carya spp. forests in the Missouri Ozarks, USA (Wallendorf et al. 2007), found that densities of early-successional species (indigo bunting, prairie warbler and yellow-breasted chat) increased after even-aged forest management (clearcutting), compared to control (no harvest) stands, whilst some mature forest species (Acadian flycatcher Empidonax virescens, ovenbird, and worm-eating warbler Helmitheros vermivorus) declined. Bird territories were recorded during before (1991-1995) and after cutting (1997-2000) in six sites (312-512 ha), three randomly assigned to even-aged management. Each even-aged site was partitioned into: clearcut (average 5.4 ha), buffer (0-100 m from clearcut), and interior (>100 m from clearcut) bird. No effects of cutting were found >100 m from clearcuts.
