This volume presents 5-year results of silvicultural treatments associated with ecosystem management research in the Ouachita Mountains of Arkansas. Results from stand-level treatments include regeneration dynamics of pine and hardwood species, effects of treatment on birds and small mammals, mast production, visual quality, oak decline, and organic matter. Pretreatment landscape findings include measurements of woody vegetation; birds, mammals, and herpetofauna; fish communities and trophic structure; hydrology; and evaluation of susceptibility to gypsy moth outbreaks.

Riparian zones are transitional, semi-terrestrial areas regularly influenced by freshwater. These areas serve as dispersal corridors for many animal and plant species and ultimately function as important reservoirs of biodiversity in altered landscapes. While much of the riparian habitat in the United States has been affected by anthropogenic activities, management actions may mitigate potentially negative influences of these activities. For example, Streamside Management Zones (i.e., riparian buffers; SMZs) are commonly implemented within managed forests to protect water quality, but may also provide habitat for riparian-associated wildlife. Yet, little research has rigorously addressed the value of SMZs for wildlife, particularly cryptic species such as amphibians and reptiles. Previous studies of herpetofauna within SMZs have focused on one or a few stream-associated species, and questions remain regarding variation among species or guilds and what role SMZs serve toward conservation of herpetofaunal diversity in managed forests. However, recent statistical advances have improved our ability to analyze large multi-species presence-absence datasets, accounting for low detection rates typical for some herpetofaunal species. This study represents an extensive landscape-scale examination of herpetofaunal communities within SMZs using a multi-species occupancy approach within the Ouachita Mountains, Arkansas, and along the Broad River in South Carolina, USA. We used a hierarchical Bayesian community occupancy model to estimate species richness and species-specific occupancy responses to SMZ and overstory characteristics. In addition to this landscape-scape investigation, we also examined the effect of harvesting on individual growth of the Ouachita dusky salamander (Desmognathus brimleyorum). We used intensive capture-mark-recapture at three headwater streams embedded in intensely managed pine forests of west-central Arkansas, employing a Before-After-Control-Impact (BACI) design. Collectively, our results indicate that SMZs surrounding small first-order streams in intensively managed forests not only protect water quality, but also can support diverse amphibian and reptile communities.

Amphibian populations have been declining for decades, and habitat alteration is one of the most influential factors leading to declines. Created wetlands can often compensate for loss of natural habitat, but little is known about amphibian population or community level responses to habitat alteration at the landscape scale. Further, they are usually constructed without knowledge of species habitat preferences. In the Ouachita National Forest of southeast Oklahoma, USA, the US Forest Service creates wetlands to promote amphibian abundance and reproductive success, but the amphibian community composition of these wetlands, and the natural wetlands in the region, are unknown. Therefore, the amphibian community composition of man-made and natural wetlands in the Ouachita National Forest, and habitat associations of amphibians in the region, were determined. Wetlands were sampled during May, June, and July of 2012 (Le Flore County) and 2013 (McCurtain County), using seining/dip netting, nighttime call surveys, and perimeter transects. Habitat variables were measured at each wetland and compared between wetland types, and species-environment relationships were analyzed using canonical correspondence analysis. Man-made wetlands had greater amphibian species richness compared to natural wetlands, and most species occurred more frequently in man-made wetlands than in natural wetlands in both counties. Amphibian species richness differed between sampling periods and wetland types in both counties, but the presence of fish did not affect species richness in man-made or natural wetlands in either county. Man-made wetlands were deeper and held water longer, but had greater open canopy and warmer water temperature compared to natural wetlands. Canopy cover and substrate were consistently the most important habitat variables influencing amphibian abundance and community structure. Man-made wetlands provide habitat for amphibians in the Ouachita National Forest, and positively impact amphibian diversity and persistence in southeast Oklahoma. Wetlands constructed in the Ouachita National Forest provide a framework for wetland construction for amphibians. Wetlands constructed for amphibians should be small but deep, have upland left intact, have vegetation planted if needed, and should be placed in the landscape appropriately to promote the persistence of multiple amphibian species.

"Southern forests provide innumerable benefits. Forest scientists, managers, owners, and users have in common the desire to improve the condition of these forests and the ecosystems they support. A first step is to understand the contributions science has made and continues to make to the care and management of forests. This book represents a celebration of past accomplishments, summarizes the current state of knowledge, and creates a vision for the future of southern forestry research and management. Chapters are organized into seven sections: "Looking Back," "Productivity," "Forest Health," "Water and Soils," "Socioeconomic," "Biodiversity," and "Climate Change." Each section is preceded by a brief introductory chapter. Authors were encouraged to focus on the most important aspects of their topics; citations are included to guide readers to further information."
