Clear or open patches in forests
A before-and-after study in mixed woodlands in Pennsylvania, USA (Yahner 2003), at the same study site as (Yahner 1987) found that three early successional species (indigo bunting Passerina cyanea, eastern towhee Pipilo erythrophthalmus and field sparrow Spizella pusilla) were more abundant and three woodland species (red-eyed vireo Vireo olivaceus, ovenbird Seiurus aurocapilla and American redstart Setophaga ruticilla) were less abundant on test plots in 2001-2002, compared with 1998-1999, following the completion of a cutting cycle. Across the entire site (both test and control plots) total bird abundance and species richness increased over the study period, with several species showing significant population increases. The authors suggest this is because the cutting management increased the heterogeneity of habitats across the site.
