Title Impact of supplemental planting of early successional tree species in bottomland

hardwood reforestation sites

Project Description Reforestation of bottomland sites on public lands, and on private lands through forest easements

under the U.S. Department of Agricultures Wetland Reserve Program and the U. S. Fish and

Wildlife Services Partners for Wildlife Program, have historically emphasized sowing acorns or

planting seedlings of heavy-seeded oaks and pecan. These heavy-seeded species are often slow

to develop vertical forest structure. Additionally, where distances to source populations of

light-seeded tree species are great, lack of invasive early-successional tree species further limits

rapid development of vertical forest structure. We will supplement heavy-seeded tree plantings with

small patches of early-successional species within reforested sites to promote vertical structure,

provide avian perches and nest sites, and thereby increase richness of woody species. Because

fast-growing species may be more impacted be weedy herbaceous vegetation than are

slow-growing trees species, we will assess different weed control measures. We predicted that

this ultimately will increase richness of avian species. Richness of woody species and breeding

birds on treated sites will be compared with reforested sites where no early successional species

were planted.
