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
Mammalian herbivory of bottomland hardwood seedlings has been listed as one of the primary causal factors of failed afforestation efforts in the Lower Mississippi Alluvial Valley (LMAV). This study examined the biological and economic effects of mammalian herbivory on recently afforested carbon sequestration sites in the LMAV. Selected seedlings of six planting mixes were observed through the first year following planting to monitor seedling survival, growth, and mammalian herbivory. It was determined that greater than 10% of selected seedlings were browsed by various mammalian herbivore species, and some species mixes were browsed in excess of 50%. Financial analyses compared alternative afforestation strategies and determined to what extent herbivore-induced seedling mortality could reduce investment returns of landowners engaged in afforestation activities. In the presence of extreme mammalian herbivory, landowner returns can be reduced by hundreds of dollars per acre and could prevent further afforestation activities in the LMAV.
