Non Technical Summary
The Appalachian region of the eastern USA is extensively forested, Appalachian forests are a globally significant ecological resource and provide economic and environmental benefits for area residents. However, the region contains extensive coal reserves, and the progressive loss of forest vegetation due to mining is of concern to area citizens, natural resource agencies, and industry. This project will investigate coal mine reclamation practices for their effects on indicators of forest ecosystem restoration success by assessing the emerging plant communities.Soil grading and seeding practices are known to influence forest ecosystem re-establishmenton Appalachian surface coal mines, but much remains to be learned about these influences. This project will extend an investigation of soil grading and seeding practices initiated in 2008. The research goal is to compare the effects of two land reclamation practices - soil grading and herbaceous seeding - on plant community restoration.The research will take place at three locations on a southwestern Virginia coal mine. At two of those locations, two soil grading (smooth-grading and loose-grading) and three reclamation seeding treatments (conventional seeding, to create dense groundcover rapidly; tree-compatible seeding, to create a moderate level of initial groundcover; and annual ryegrass seeding, to create the lowest level of initial groundcover) were installed as experimental plots. These sites were hand-planted in early 2008 and early 2009 with seedlings of 13 native tree species. A third location, two of experimental treatment combinations (conventional seeding with smooth grading; tree-compatible seeding with loose grading) were established and planted with native trees in 2006 and 2007, respectively. Measurement plots for both woody and herbaceous vegetation have been established on the 2008 plots, and will be established in a similar manner on the 2006 and 2007 reclaimed areas. All trees within the woody vegetation measurement plots will be identified, enumerated by species, and measured for height and diameter. Herbaceous groundcover within the herbaceous-vegetation will be assessed for ground cover, overall and by species.Resultant data will be analyzedand evaluated to determine how the soil grading and seeding treatments affected survival and growth of planted trees, volunteer establishment of unplanted trees and shrubs, and herbaceous groundcover. These metrics will be evaluated for treatment effects overall, by species, and by several species groupings (planted vs. volunteer; native vs. exotic; invasive vs. non-invasive). Results will be interpreted to compare the effects of soil grading/seeding treatment combinations on measures of reclamation and ecosystem restoration success, as stated by the objectives.Project results will generate improved knowledge concerning effects of mine revegetation practices on the emerging plant community's development. Results will be communicated to the coal mining industry, agencies that regulate the mining of coal, area citizens, and the ecosystem restoration science community. Results will be communicated in research and outreach publications; presentations at a scientific conference and at a meeting for reclamation practitioners; and to parties participating in field tours of reclamation sites that will include the experimental areas. Project results will contribute to improved mine revegetation practices by the coal industry on mine sites where restoration of forested ecosystem is the reclamation goal.

Goals / Objectives
The research goal is to compare the effects of two land reclamation practices - soil grading and herbaceous seeding - on plant community restoration.Specific objectives are to determine the effects of soil grading and seeding practices on:Indicators of land reclamation success that are evaluated by mine regulatory agencies: woody species density and total groundcover.Indicators of plant community restoration success, including both native and non-native plant species recruitment; development of woody cover and biomass comprised of native species; plant community diversity; and planted trees' growth.
Project Methods
The experimental study areas to be used in this research have been prepared by mining firms during reclamation operations of active coal mines. However, one site was subsequently removed by the mining company. The remaining experimental sites are on sloped land that is typical of Appalachian mines that are being restored to approximate original contour; but these areas differ in aspect and soil type.On each experimental area, relatively uniform topsoil substitute materials were placed to depths of 4 feet or greater. Spoil materials on the sites were comprised of mixtures of weathered sandstone, unweathered sandstone, and unweathered siltstones but from different lithologic units. Mining firms were asked to select sites approximately 6 acres (2.4 ha) in size for use in the research.Two site preparation treatments were applied, with each treatment applied in half of each experimental area: "Loose Grading" and "Smooth Grading."Three herbaceous revegetation treatments were applied over each loose-graded and smooth-graded area. Annual Ryegrass is simply annual ryegrass, fertilizer and mulch. The Tree Compatible seed mix is similar to a seed mix that is recommended to mining firms (Burger et al. 2009) for the purpose of encouraging survival and growth by planted trees while ensuring that regulatory requirements for groundcover are satisfied. It is comprised of non-sod-forming bunch grasses and of legumes selected for slow-growing and sprawling forms. The Conventional seed mix is comprised of rapidly-growing grasses and legumes and is designed for a tall, thick green cover that maximizes erosion control quickly. The Conventional seed mix is identical to that typically applied by a commercial seeding contractor that works throughout Virginia's coalfields.A commercial tree-planting contractor planted a selection of native hardwood trees along with woody wildlife/nurse species on all three sites over a period extending from December 2007 through February 2008. This planting mix is consistent with the Forestry Reclamation Approach as recommended by the investigator to the mining industry.Task 1: Assess VegetationVegetation assessment will proceed using methods similar to those applied in 2008 and 2009. Five 0.02-ha, circular, woody-plant sampling plots were established on each treatment plot.All woody plants (trees and shrubs) within measurement plots, both planted and volunteer, will be enumerated by species. Height will be measured for each individual as vertical distance from the soil surface to the highest live bud. Woody plant density will be determined for each species and overall as number of live trees ha-1. To the extent possible considering species, physical location on the ground surface, and data obtained in 2008-2009, each growing tree will be identified as either planted or volunteer. Survival of planted trees will be determined by dividing the number of trees counted by the number of trees tallied in June 2009, after they were replanted. Average height growth will be determined for each planted tree species by subtracting the average height recorded in June, 2009, both from measured heights, and from the overall average. An average diameter for each living tree's canopy also will be recorded.Four, 0.0004-ha circular herbaceous vegetation sampling plots were nested within each woody plant measurement plot. Within each, an ocular estimate of total living and dead herbaceous ground cover, expressed as a percent of ground area, will be determined by comparing observed coverage with diagrams of various coverage rates. All plants within each measurement plot will be identified to the lowest practical taxonomic level, usually species. Ground coverage within each herbaceous measurement plot will also be estimated for each herbaceous taxon present. Where different taxa overlap vertically, the overlapped ground area will be assigned to the overtopping species.Samples of plant taxa that cannot be identified in the field will be collected to aid identification. Plant taxa will be separated into "seeded" versus "volunteer" categories to distinguish origin. Since many of the seeded species are classified as invasive (SE-EPPC 2013), all taxa used for any of the three seeding treatments will be classified as "seeded" even if not originally seeded in the measurement plot where it is recorded. Plant taxa will also be classified by nativity (native vs. non-native, as defined by USDA (2013)), and invasivity (invasive, as defined by SE-EPPC, 2013, vs. non-invasive), and type (herbaceous vs. woody shrubs and trees). Total living herbaceous ground cover will also be subtotaled for origin, nativity, and invasivity using the above classifications.Richness (overall, and by origin, nativity, invasivity, and plant type) will be quantified for each treatment plot as the number of plant taxa present. Total richness, the number of classified plant taxa found across all blocks, will also be computed for each treatment and overall and by origin, nativity, and invasivity. Diversity will also be calculated for all treatment plots using the Shannon index as -Σpilnpi, where pi is the ratio of each taxon's ground cover within a plot to the total ground cover within a plot. The Shannon index will be separated into components representing vegetation types (origin, nativity, and invasivity) by computing -Σpilnpi separately for component vegetation types with pi as the total living ground cover for the treatment plot. These plant community composition metrics will be computed for herbaceous taxa only, and for the full plant community (herbaceous + woody).Task 2: Sample SoilsSoil samples will be taken from areas adjacent to each herbaceous vegetation sampling plot and composited by woody vegetation sampling plot. The composited samples will be sent to the Virginia Tech Soil Testing Laboratory for analysis. Primary soil properties of interest are soil pH, soluble salts, and organic matter (loss on ignition). More complete soil analyses are not proposed considering both the soil analyses conducted in 2008-2009 and current resource limitations.Task 3: Analyze and Interpret DataResults will be interpreted to compare the effects of soil grading/seeding treatment combinations on measures of reclamation and ecosystem restoration success, as stated by the objectives. Primary analysis will apply analysis of variance (ANOVA) to results from the original split-plot design which occurs as two replications established in 2008. In addition as a secondary analysis, a t-test will be applied to compare effects of treatment combinations present at three replications (i.e. both within the 2008 experiment and on the areas reclaimed operationally in 2006 and 2007): Loose grading / tree-compatible seeding vs. smooth grading / conventional seeding. Statistical analyses will be interpreted for significance at α = 0.05.. The validity of the following hypotheses will be evaluated statistically:Experimental treatments will have no effect on total herbaceous groundcover.The combined Loose Grading / Tree Compatible Seeding treatments will produce higher density and richness of native herbaceous ground cover than the combined Smooth Grading / Conventional Seeding treatments.The combined Loose Grading / Tree Compatible Seeding treatments will produce higher densities and growth of planted trees than the combined Smooth Grading / Conventional Seeding treatments.The combined Loose Grading / Tree Compatible Seeding treatments will produce higher densities of volunteer native trees than the combined Smooth Grading / Conventional Seeding treatments.Experimental treatments will have no effect on densities of non-native invasive trees and shrubs.

Target Audience:Coal mining industry personnel who are involved with mine reclamation activities; personnel with regulatory agencies that oversee mine reclamation activities; students in Virginia Tech classes as well as those from UVA who are learning about mine reclamation and remediation practices. Changes/Problems:Statistical analysis proved problematic. A major source of the problem was a decision to analyze the experimental results for block effects, which was not part of the experimental design and caused severe limitation to degrees of freedom. The decision was made to analyze for block effects because data analysis revealed that soil properties (block effects) had a major effect on experimental outcomes. As a result of that problem, a significant effort was required to ensure the adequacy of the statistical procedures that were employed. What opportunities for training and professional development has the project provided?In spring 2014, two graduate students assistedwith field sampling. This experience enhanced their professional training. September 2014: A field tour of the experimental site was conducted for ~30 students enrolled in Crop and Soil Environmental Sciences 3644, Plant Materials for Environmental Restoration, and the course instructor was Dr. A.O. Abaye. Experimental goals, activities, results to date, and significance were reviewed with the students. April 2014, April 2015, and April 2016: Field tours of the experimental site were conducted for students enrolled in Mining Engineering 4544, Mine Reclamation and Environmental Management, and the course instructorwas Dr.Emily Sarver (approximately 40 students per year, 120 students total). Experimental goals, activities, results to date, and significance were discussed with the students. These students are senior-level mining engineering students who are preparing to enter the mining industry, where many will be in positions that will enable them to apply the knowledge gained. How have the results been disseminated to communities of interest?In April 2014, April 2015, April 2016, and April 2017, field tours were conducted at Powell River Project Research and Education Center for participants in Virginia Natural Resources Institute (VNLRI), a program for natural resource leaders that is led by faculty University of Virginia, Charlottesville. The tours visited reclaimed coal-mine areas where mine reforestation techniques, including those which are under study, are being applied. Research results and their significance were discussed with the VNLRI fellows, who represent industrial firms, natural resource agencies, and educational institutions from throughout the state of Virginia (approximately 35 VNLRI Fellows per year, 140 total). In August 2014, the investigator made a presentation entitled "Reclamation Practice Influences on Trees on a Virginia Mine Site After Six Years" at Appalachian Regional Reforestation Initiative Annual Meeting at Frostburg MD. This presentation described preliminary research results for an audience of mining industry and regulatory agency personnel who have responsibilities that concern mine reclamation and revegetation, subjects of the research. In June 2015, a mine reforestation workshop was held at the National Meeting of the American Society of Mining and Reclamation. The investigator was co-organizer and session moderator for this workshop, which was attended by approximately 40 people. Attendees included representatives of the mining industry and regulatory agencies. In August 2016, the investigator made a presentation "Reclamation practice influences on the post-mining plant community at a Virginia mine site after six years" at the 2016 Conference of the Appalachian Regional Reforestation Initiative in Knoxville TN. This presentation described complete research results for an audience of mining industry and regulatory agency personnel who have responsibilities that concern mine reclamation and revegetation, subjects of the research. In August 2016 following the above presentation, the investigator was a presenter for a panel discussion on the topic "Applications of the Forestry Reclamation Approach" at the 2016 Conference of the Appalachian Regional Reforestation Initiative in Knoxville TN. This presentation described applications of research findings for an audience of mining industry and regulatory agency personnel who have responsibilities that concern mine reclamation and revegetation. In September 2016, a field tour was conducted at Powell River Project Research and Education Center areas where research findings are being applied. The field tour was conducted with approximately 10 visitors including students from University of Virginia's College at Wise. In June 2015, August 2015, and February 2017, Forest Reclamation Advisory publications were completed under the investigators' leadership. These Advisories are published and disseminated by Appalachian Regional Reforestation Initiative, US Office of Surface Mining. Co-authors include scientists fromthroughout the region. These Advisories are disseminated to mining industry and regulatory agency personnel who are directly involved with mine reforestation practices by US Office of Surface Mining. What do you plan to do during the next reporting period to accomplish the goals? Nothing Reported

Impacts
What was accomplished under these goals? In 2008, experimental areas were established. In 2014, plant community status on the two experimental areas (planted with trees in early 2008) and the two operational areas (planted with trees in early 2006 and 2007) were assessed. In spring 2014, all trees growing within sampling plots established on the experimental areas and the operational areas were tallied by species and measured for height and diameter. In mid-summer, soil samples were taken from the sampling plots at two depths: at the surface, and about 6 inches below the surface. In late summer, vegetation sampling plots were established within the tree-sampling plots, and all vegetation growing within each vegetation sampling plot was identified by species and by groundcover class; and all observed species were classified as either planted or non-planted volunteer; and as either native or non-native (alien). In 2015, data were analyzed and a report to sponsors and stakeholders was prepared. In 2016-2017, a manuscript was prepared and submitted to a scientific journal. The initial manuscript, was not accepted by the journal. The manuscript was revised and submitted to a different journal; the journal editor's response to the submission included a request for additional information on statistical analyses. Advice was obtained from statistical consultants and the additional statistical information was prepared for addition to the manuscript. Research findings included results that provide clear guidance for forest restoration practice on coal surface mines and with consistent results asexpected based on smaller-plot experiments. Larger trees of native taxa were found on annual-ryegrass and tree-compatible seeded areas. Native understory plant cover was greater on areas seeded using tree-compatible plant species than on conventionally seeded areas. Where soils were of weathered-sandstone origin and mildly acidic like native soils, native trees grew larger and established greater canopy than in areas with alkaline-siltstone origin soils, where primary plant-community components were exotic. Soil-material selection and reclamation seeding influenced the developing plant communities as expected. Native trees established and grew where these practices were applied in accord with restoration science, and native understory plants established and proliferated in association with the native tree canopy. Exotic plants with potential to persist were prominent in all reclamation areas, but werelargest and most-prominent where alkaline soil materials were used for reclamation.

Book Preparation: Over the period extending from 2005-2015, I served as coordinating editor and co-author for 12 Forest Reclamation Advisories, outreach publications to the mining industry that are developed with peer review and were published by US Office of Surface Mining. In 2016, my efforts were instrumental to an effort by US Forest Service to republish these advisories as a numbered US Forest Service publication. That publication effort is being led by Dr. M.B. Adams of US Forest Service. Re-publication of these advisories by the US Forest Service will lead to their inclusion on the US Forest Service publications' database, and will expand their audience.
