The American chestnut’s fast growth rate, early nut production, and quality of timber make it a valuable tree for use in coal mine restoration projects (Figure 1). This species tolerates a wide range of ecological conditions, including dry soils and low pH, which are typical of some sites previously mined for coal. Experimental planting methods are currently being studied to determine protocols most conducive for establishing chestnut trees on these sites. The Forestry Reclamation Approach (FRA) proposed by the Appalachian Regional Reforestation Initiative (ARRI) recommends the selection of proper soil substrate, a deep rooting zone, appropriate herbaceous vegetation, and the …

We have been planting blight resistant American chestnut seedlings on reclaimed coal mined areas in Southeastern Ohio, which was once within the natural range of the American chestnut. Towards the goal of restoring the American chestnut, we are testing suitable sites that can aid survival, growth and establishment of planted seedlings pre-inoculated with ectomycorrhizal fungi. Prior to the arrival of the chestnut blight fungus, pathogens of the genus Phytophthora were introduced in the USA that were responsible for the “ink disease” or “root-rot” resulting in wide-spread death of chestnut trees in southern states. Although these pathogens were not observed elsewhere, …
Ailanthus Altissima (Tree-Of-Heaven) Interferes With Beneficial Symbionts With Negative Impacts On Oak Regeneration, Jenise Bauman, Caitlin Byrne, Shiv Hiremath
Ailanthus Altissima (Tree-Of-Heaven) Interferes With Beneficial Symbionts With Negative Impacts On Oak Regeneration, Jenise Bauman, Caitlin Byrne, Shiv Hiremath

The invasion of Tree-of-Heaven (Ailanthus altissima) has been documented in disturbed landscapes leading to biodiversity loss and degradation of ecosystem function. Ailanthus interferes with the restoration of native species by its aggressive growth habit, alteration of nutrient cycles, and allelopathic chemical production. Recent studies suggest that allelopathy has a negative effect on the growth of red oak (Quercus rubra), possibly by interfering with the symbiosis of beneficial ectomycorrhizal fungi (ECM). This fungal symbiont is essential for healthy tree growth and the unavailability of these fungi may impede the success of seedling regeneration. This study investigated the effects …
