Research Interests
I am working on research in oak-dominated forests of the Ozark-Ouachita Highlands, where oak-hickory is the most extensive forest type, covering over 15 million acres. The majority of the work is applied, and considerable effort is made to bring application of research results to resource managers and others. I am working to develop methods for forest restoration, sustainability, and to forecast long-term, large-scale changes in forests throughout the south and beyond. I am working to understand factors associated with oak mortality and on methods to minimize its impact. I also manage two experimental forests totaling over 5,000 acres.
Past Research
Marty has worked for the Southern Research Station since 1998. He has published more than 70 scientific manuscripts and other publications; given more than 90 scientific presentations; given invited talks in China and Russia; done collaborative research with university and government scientists; taught classes at both The Ohio State University and Purdue University; and presented over 40 technical transfer talks, workshops and field days. In addition he holds adjunct faculty status at several universities.
Why This Research is Important
Restoration of forest species is important for maintaining the integrity and sustainability of forests. While forecasting landscape change is an essential quantitative tool for understanding the large-scale, long-term, cumulative effects of forest management. This knowledge is required for management of National Forests and equally crucial to private forestland owners who own the majority of the forests in the eastern United States.

2009—Current
Mission: Dr. Spetich is a Research Forest Ecologist with the Southern Research Station’s Research Work Unit (RWU) FS-SRS-4157, Upland Hardwood Ecology and Management, with unit headquarters located in Asheville, NC. He has leadership responsibility for upland hardwood research development and administration. The duty station of the scientist is Hot Springs, AR. The mission of the unit is to develop and disseminate knowledge and strategies for restoring, managing, sustaining, and enhancing the vegetation and wildlife of upland hardwood-dominated forest ecosystems of the central region of the eastern United States. The research integrates theory, experimentation, dissemination and application of results. Research is designed to enable land managers to better predict changes in forest structure, composition, and habitat quality and to develop methods to meet land management, conservation, and restoration goals for upland hardwood forests. Duties: Dr. Spetich plans and conducts research on ecology and silviculture of upland hardwood forests; the scientist is also the Unit’s primary contact west of the Mississippi River for science delivery of research products and expertise in upland hardwood forest ecology, silviculture and forest dynamics to a wide range of customers. Research emphasis is on oak-dominated forests of the Ozark-Ouachita Highlands, where oak-hickory is the most extensive forest type, covering over 15 million acres. The majority of the work is applied, and considerable effort is made to bring application of research results to resource managers and others. Accomplishments: My research addresses a range of spatial and temporal scales. I have conducted applied forest ecology and silvicultural research in ecosystems that range from xeric oak forests of the Ozark Highlands to mesophytic forests of the Central Hardwood Region by creatively expanding concepts and methods. I continue to develop new management methods to regenerate and restore oak in areas where more shade tolerant species are successionally replacing it. I initiated a complex, integrated set of long-term studies to maintain species diversity while promoting natural and artificial oak reproduction. These studies use prescribed fire, other vegetation control methods, group openings, improvement harvests, shelterwoods or a combination of these methods, as well as taking advantage of natural disturbances. I develop opportunities to creatively demonstrate and disseminate research information. I also initiated several short-term cooperative studies on fire history, aforestation, natural regeneration, age, and spatial analyses to help answer other key research questions. My studies are designed as integrated phases of the overall research with the objective of understanding the dynamics of upland hardwood forests across the landscape and through time. I developed new hypotheses, concepts and management methods to extend existing knowledge for upland hardwood forest dynamics through time. The information gained and techniques developed are distilled into easily understood applications; providing valuable new guidance for resource managers. For instance, the oak underplanting success model (OAKUS) for upland oak-hickory forests in the Ozark Highlands uses regression and probabilistic statistical models to predict success of underplanted northern red oak seedlings 11 years after planting. OAKUS is located at an Internet site that any forest manager with a PC can access (http://ncrs.fs.fed.us/oakus/). The OAKUS website allows managers to easily and interactively solve complex, site specific underplanting problems.

2001—2009
The scientist is a Research Forester with the Southern Research Station’s Research Work Unit (RWU) FS-SRS-4106, Managing Upland Forest Ecosystems in the Midsouth, with unit headquarters located in Monticello, AR. The scientist has leadership responsibility for upland hardwood research development and administration. The duty station of the scientist is Hot Springs, AR. The mission of the unit is to provide scientific information to understand, manage and sustain the ecological processes, structures, and benefits of mixed loblolly-shortleaf pine and pine-hardwood forests of the upper West Gulf Coastal Plain, the shortleaf pine and pine-hardwood forests of the Ouachita and Ozark Mountains, and the upland oak-hickory forests of the Ozark Mountains. The RWU has three assigned problem areas: (1) our understanding of the factors that govern the establishment and early development of natural regeneration of pines and hardwoods limits our ability to maintain the productivity and sustainability of forest stands in the Midsouth, (2) our ability to apply and modify silvicultural practices in immature and mature stands of naturally-regenerated pines and hardwoods of the Midsouth is limited by our understanding of the ecological patterns and processes that govern stand dynamics and development, and (3) our ability to ensure the health, sustainability, and productivity of upland forests in the Midsouth is limited by our incomplete understanding of the cumulative hydrological and ecological effects that result when management activities are imposed across a landscape. The RWU’s scientific team is developing low-cost and low-impact silvicultural systems for natural stands across a wide range of forest types (upland hardwood, mixed pine-hardwood, and pine) and physiographic regions (Interior Highlands and Upper Coastal Plain). The scientist’s work supports the Southern Research Station Strategic Plan Cross Cutting Theme, “Sustainability and Productivity of the Interior Highlands Ecosystem.” This theme is an interdisciplinary program that encompassed the mission of SRS-4106 during the period that this PD covers.
