Bachman's sparrow inhabits areas with open overstories. In sites in eastern Texas of varying age since clearcutting, study areas occupied by Bachman's sparrows had significantly (p<0.01) fewer short (≤ 10 feet (3m)) and tall (>10 feet (3m)) trees than unoccupied study areas. In longleaf and loblolly pine stands of varying ages and under different management in South Carolina, plots occupied by Bachman's sparrows consistently had low volumes of vegetation from 7 to 13 feet (2–4 m) above ground compared to unoccupied sites. In middle-aged and mature forests of Georgia composed primarily of loblolly pine, Bachman sparrow densities were negatively associated with tree/shrub volume and vegetation volume from 7 to <16 feet (3 to <5 m). In loblolly and shortleaf pine plantations of Arkansas, Bachman's sparrow breeding areas had significantly lower percent canopy cover (p<0.001), shorter woody vegetation (p≤0.01) and fewer trees (p<0.001) and shrubs (p≤0.05) than unoccupied sites. In south-central Missouri, Bachman's sparrows occurred in glades with less than 30% woody cover, and occupied glades had significantly (p≤0.05) lower percentages of deciduous and coniferous saplings, deciduous and coniferous trees, and total woody vegetation. Mid-story density was marginally (p=0.055) greater on unoccupied sites, and Bachman's sparrow abundance was significantly (p=0.043) negatively correlated (r= –0.446) with mid-story density in longleaf pine woodlands of northwestern Florida. However, relative abundance of Bachman's sparrows was not significantly (p=0.107) associated with canopy cover and there were no significant (p=0.133) differences in canopy cover between occupied and unoccupied sites.
