Book Description
The Mississippi Alluvial Valley (MAV) has undergone losses of bottomland hardwood forests due to agricultural conversion. Hardwood establishment on marginal croplands has been proposed to mitigate effects of deforestation and related loss of carbon-capture potential. However, a possible concern with reforestation is low seedling survival from mammalian herbivory. I surveyed two afforested fields in the MAV of northwest Mississippi to assess damage and mortality from four herbivores on nine species of hardwood seedlings (n = 868). Percentage survival of seedlings was 35%. Mortality of seedlings caused by herbivores was: hispid cotton rat (Sigmodon hispidus; 6.45%), rabbit ((Sylvilagus spp.; 1.95%), pine vole (Microtus pinetorum; 2.99%), and white-tailed deer (Odocoileus virginiana; 0.69%). Of surviving seedlings (n = 316), 10.82% were damaged by cotton rats, pine vole (2.99%), rabbit (8.06%), and deer (7.02%). Green ash (Fraxinus pennsylvanica), water oak (Quercus nigra), and Nuttall oak (Quercus nuttallii) had greatest survival.

Book Description
The Mississippi Alluvial Valley, which can be broadly subdivided into the Holocene Deposits section and the Deltaic Plain section, is a 24.9-million-acre area generally approximating the alluvial floodplain and delta of the lower Mississippi River. Its robust agricultural economy is maintained by a largely rural population, and recreational resources draw high visitation from nearby urban centers. The Mississippi Alluvial Valley forms a key corridor for migratory animals, and the Mississippi River has been developed as a vital conduit of commerce for much of North America. Although forest land use currently makes up only 28 percent of the Mississippi Alluvial Valley, bottomland hardwood forests and coastal swamps remain invaluable for producing forest products, sustaining biodiversity, providing recreational opportunities, and performing essential ecosystem services. Forecasts generated by the Southern Forest Futures Project provide science-based projections of how alternative futures of economic growth, population growth, climatic patterns, and a range of forest threats could drive potential trajectories of land use, forest conditions, water resources, recreational resources, and wildlife habitats across the Southern Region. This report identifies findings from the Southern Forest Futures Project that are relevant to the Mississippi Alluvial Valley, expands on the relevant findings through additional science synthesis and analysis, and outlines noteworthy implications of the alternative futures to forest-based resources and ecosystem services of the Mississippi Alluvial Valley.

Book Description
This report is a literature review concerning the impacts of flooding regime modification on bottomland hardwood forest wildlife habitats of the lower Mississippi Valley. Documented effects on forest vegetation and wildlife populations are described. The composition and structure of the bottomland are an important determinant of the quality and type of wildlife habitat available. These forest characteristics are, in turn, largely influenced by the flooding regime. In general, overstory diversity and perennial understory diversity and productivity are lowest in near-permanently flooded habitats and increase in areas flooded less frequently and for shorter periods of time. Nonflooded areas are often, but not always, less diverse and productive than infrequently flooded areas. A permanent change in flooding regime is likely to cause a gradual change in composition and structure, resulting in forest characteristics similar to those normally found under such hydrologic conditions. Tree growth, regional habitat diversity, and land clearance patterns may also be influenced by modifications to the hydrologic regime.

Book Description
At one time, the Lower Mississippi Alluvial Valley was covered by almost 25 million acres of forest. By the mid-1980s, all that remained of the valley's forested land was roughly 6.6. million acres. This report addresses a gap in data about this land providing, for the first time since 1986, comprehensive new estimates of forest area, volume, carbon, and tree species stocking change.
