Avian Habitat Use in a Chronosequence of Bottomland Hardwood Forest-Restoration Sites

摘要: Since the 1950s, anthropogenic activity has caused loss of millions hectares bottomland hardwood forest in Upper Mississippi River Valley, causing population declines bird populations. Restoration these stands been ongoing for past 2 decades. We assessed species presence on sites Valley to quantify diversity and relate habitat conditions sites' age since restoration. observed higher mean diversities at mature bottomland-forest during spring autumn, but nested ANOVAs indicated no significant differences among restoration-age categories spring. During 15–23-y were significantly different from <7-y category. Predictive models differed species, forest-dwelling birds was positively related forested conditions, such as tree height density. Overall, our analyses show that a variety use sites, we suggest further exploration how assemblages may change future surveys.
