Alliaria petiolata is an invasive biennial herb that poses a substantial threat to various ecosystems across the United States. Imazapic herbicide can control A. petiolata infestations, but there is limited peer-reviewed data on impacts of pre-emergent imazapic spraying to forest floor communities. This research examined the impacts of pre-emergent imazapic (0.84 kg/ha) with Pentra-Bark® surfactant on ground cover of A. petiolata and the spring perennials Claytonia virginica and Erigenia bulbosa. Experimental populations in randomized blocks within two forest stands in central Kentucky received the following treatments at 0.84 kg ai/ha: imazapic with Pentra-Bark®, glyphosate with Pentra-Bark®, Pentra-Bark® alone, and …
Sustainability And Economics Of White Oak (Quercus Alba) Timber Supply In Kentucky, Gaurav Dhungel
Sustainability And Economics Of White Oak (Quercus Alba) Timber Supply In Kentucky, Gaurav Dhungel
Theses and Dissertations--Forestry and Natural Resources
Sustained timber supply relies upon balanced forest age distribution, where the level of harvesting and mortality is compensated by regeneration and growth among younger age classes. However, current forest inventory trends from the white oak growing region reveal sustainability threat from declining white oak regeneration and recruitment leading to disproportionate inventory structure. Consequently, there exists growing concern among stakeholders on long-term sustainability of white oak timber and its economic implications, particularly in Kentucky, because of the significance of the species to the state’s economy. This research aims to examine past and current inventory levels of white oak in Kentucky using …
