Spring mornings are filled with the songs of birds migrating back from their tropical winter homes.

Individuals from these and other groups have expressed interest and requested information as a result of our project during our presentations. During this research project we have focused on involving and mentoring both graduate and undergraduate students. Four graduate students have been actively involved in the project, and three of them completed their Master of Science theses.

The fourth student has collected the data that will be needed to develop their graduate thesis research. We hired and then trained two new undergraduate students each summer to assist with data collection during the field season. These students gained valuable field experience by assisting us with relocation, the resampling of the permanent plots, and data entry and management. Jointly we supervised the students as they completed all the data entry and checking of the data sets for accuracy. We also employed part-time undergraduate students enrolled in our School to assist with the data sets and equipment maintenance.

How have the results been disseminated to communities of interest? We have begun to present results from our work at several conferences, conventions, and meetings e. In a major peer-reviewed article published in in Forest Ecology and Management, we examined the structural and compositional shifts in forests undergoing mesophication in southeastern Ohio.

As chronicled in the Products section, we have had several opportunities to formally present various aspects of this research project at a diversity of professional society and other meetings.

The posters and papers we presented at the Society of American Foresters National Conventions were all published in abstract form later in the Journal of Forestry. We have also made presentations explaining how we were assessing change in hardwood forests of the Wayne National Forest of southeastern Ohio during the Sustaining oak forests in the 21st century through science-based management Oak Symposium, in Knoxville, TN; and in at the Central Hardwood Conference in Bloomington, IN.

Over the past four years, we have been asked to present research results on multiple occasions to Wayne National Forest, Ohio Department of Natural Resources-Division of Forestry, and Northern Research Station staff, including as part of the work collectively to develop a collaborative and stewardship partnership of forests across southeastern Ohio.

In we provided summary data from our project to be included in the Wayne National Forest assessment phase of their Forest Plan Revision. We will continue to interact with our collaborators about our plans for future field work and analyses, as well as sharing research results, answering questions, and addressing their concerns. What do you plan to do during the next reporting period to accomplish the goals?

Although this project has terminated, a new project has been initiated that involved this research focal area in southeastern Ohio. We plan to continue the field work of plot relocation and resampling on the third and final unit Ironton of the Wayne National Forest.

We plan to resample all the remaining plots on the Ironton Unit that can be correctly relocated. As in the past, we will enter the new data collected on office days during Impacts What was accomplished under these goals? During this reporting period, we continued analyses of data collected on the Athens and Marietta Units of the Wayne National Forest. As previously reported, we completed the planned data collection on both units of and 88 relocated permanent plots, respectively.

The main focus of this research project is examining the regional compositional shifts and successional trends by remeasuring permanent sample plots in unglaciated southeastern Ohio that were originally established in Overall, we are addressing our objective of modeling changes in specific forest ecosystem types undergoing mesophication in the Central Appalachian region. Since the foundational taxa of oak Quercus spp. Overall, American beech sapling density nearly doubled between the two sampling periods, while both maple species declined in sapling density by more than half.

Our models showed sugar maple Acer saccharum was positively associated with high pH, and red maple with low pH. Red maple was positively associated with upper slopes while American beech was positively associated with lower slopes. These results will help forest scientists and managers understand potential future compositions of currently oak-dominated forests, in similar mature stands that have not been recently disturbed.

These mesophytic species are likely to increase in forest canopies within our study area, and each species provides different ecosystem services and economic values than oak and hickory. Utilizing our data from the two time periods, mixed logistic regression was used to determine that three red oak subgenus Erythrobalanus tree species had higher mortality rates Northern red oak Quercus rubra showed more sensitivity to a priori topographic and edaphic predisposing factors than the other four tree species.

The species with the highest background mortality rate was scarlet oak Quercus coccinea; In our models, northern red oak mortality rate was associated with more mesic slope positions, shallower solum, more acidic soil, and older stand ages. Pignut hickory and chestnut oak mortality rates were associated with higher basal area on the plot, while white oak mortality rate showed the opposite pattern.

These data suggest that red oak subgenus trees in mature, unmanaged forests in the study area will become increasingly uncommon relative to white oak subgenus trees, as the result of higher mortality rates particularly on more mesic topographic positions, in shallower or more acidic soil, and in older stands.

Oak and hickory are highly valuable to wildlife; therefore, our investigations of their regional mortality patterns can provide information on the future type and longevity of habitat quality for many animal species. In summary, these and our other observed trends in the both the overstory and understory may ultimately lead to shifts in the dominant tree species in unmanaged stands in the region. Our results also suggest that these forest ecosystem types are becoming more susceptible to novel disturbances e.

Cleveland, OH. Individuals from these and other groups expressed various interests in our project during our presentations.

During this reporting period there we have continued our major focus on involving and mentoring both graduate and undergraduate students. Four graduate students have been actively involved in the project, and two of them completed their Master of Science theses. The third student has collected the data that will be needed to develop their graduate thesis research.

As in the past, we hired and then trained two undergraduate students to assist with data collection during the entire field season. These students gained valuable field experience by first assisting us with relocation, and then with the resampling of the permanent plots. We supervised the students as they completed all the Marietta Unit data entry and checking of the data sets for accuracy.

These students were either undergraduate or graduate students in our School. We have begun to present some of our results from our work on the Athens and Marietta districts.

In a major peer-reviewed article published in Forest Ecology and Management, we examined the structural and compositional shifts in forests undergoing mesophication in southeastern Ohio. As noted in the Products section, we have had opportunities to formally present various aspects of this research project at professional society and other meetings. Specifically, we presented a poster based on local oak and maple dynamics at the Society of American Foresters National Convention, and the abstract based on the presentation was published in the Journal of Forestry.

We also made a presentation about how we are assessing change in hardwood forests of the Wayne National Forest of southeastern Ohio during the Oak Symposium Sustaining oak forests in the 21st century through science-based management in Knoxville, TN. In addition we have informally presented research results to Wayne National Forest, Ohio Department of Natural Resources-Division of Forestry, and Northern Research Station staff as part of our work collectively to develop a collaborative and stewardship partnership of forests across southeast Ohio.

We will continue to interact with our collaborators about our plans for the field work during the next field season, as well as sharing research results and answering questions.

During the upcoming field season, we plan to undertake plot relocation and resampling on the third and final unit Ironton of the Wayne National Forest.

Then, we plan to resample all plots on the Ironton Unit that can be correctly relocated. As in the past, we will enter the new data collected on office days during the summer. During this reporting period, we conducted further analyses of data collected on the Athens Unit of the Wayne National Forest, while we completed the planned data collection from 88 relocated permanent plots on the Marietta Unit.

In this research project, we are examining the regional successional trends by remeasuring permanent sample plots in unglaciated southeastern Ohio that were originally established in In our article entitled, "Structural and compositional shifts in forests undergoing mesophication in the Wayne National Forest, southeastern Ohio" published in in Forest Ecology and Management we were able to address our objective of modeling change in specific forest ecosystem types.

We suggest that these and the other observed trends in the understory may ultimately lead to shifts in the dominant trees species in unmanaged stands in the region. As mentioned above, we resampled a total of 88 permanent plots this field season on the Marietta Unit. These plots were originally selected to represent relatively undisturbed forest stands at least 94 years old in The rates of change across slope aspects and slope positions were examined using our previously developed Ecological Land Type ELT classification system.

White oak Quercus alba was the dominant tree species, as it had highest levels of importance value of any tree species in the initial sampling period This species exhibited its largest decline in importance value on northeast-facing slope aspects Preliminary analyses are indicating that the species of the red oak group have higher mortality rates on these plots compared with those of the white oak group.

These results suggest that in these regional forest ecosystems oak species are not replacing themselves in these second-growth ELTs, even in many ecosystem types thought of as favorable to oak species. These changes also have the potential to greatly modify wildlife habitat conditions and impact numerous mammal and bird species.

Society of American Foresters National Convention. Albuquerque, NM. Structural and compositional shifts in forests undergoing mesophication in the Wayne National Forest, southeastern Ohio. Forest Ecology and Management During this reporting period there has been a major focus on involving and mentoring both graduate and undergraduate students.

Three graduate students have been actively involved in the project, and two of them completed their Master of Science theses. The third student collected pilot data during the field season that will be needed to develop their graduate thesis proposal.

For the field season, we hired and then trained three undergraduate students in the field to assist with data collection. These students and another undergraduate student gained valuable field experience by assisting us with relocation of the permanent sample plots.

As completed for the Athens Unit, we have finished any needed re-entry and checking of the , , and data sets for the Marietta Unit, and we worked with two undergraduate student research assistants and a graduate student to enter the newly collected data.

We are continuously working to ensure excellent data quality and efficient organization and storage of the data files. These students were either undergraduates in our School or from other departments within the University. We have begun to present some of our preliminary analyses based on completed analyses of the data sets.

As noted in the Products section, we have had opportunities on five occasions to formally present various aspects of this research project and some results at professional society and other meetings. We also presented two posters based on vegetation-environmental relationships for presentation at the Society of American Foresters National Convention, and abstracts of both were published in the Journal of Forestry. In addition we have presented preliminary research to Wayne National Forest, Ohio Department of Natural Resources-Division of Forestry, and Northern Research Station staff on our results as we work collectively to develop a collaborative and stewardship partnership of forests across southeast Ohio.

We continue to share with our collaborators details concerning planning and executing the field work, as well as data analyses and research results. Using the valuable experience we have gained both in the field and from analyzing the data, during the upcoming field season we will complete the processes of plot relocation and resampling on the Marietta Unit of the Wayne National Forest.
