Identification and Distribution of Fungal Pathogens Associated with Loblolly Pine Defoliation and Tree Mortality in the Southeastern United States

Datta, Debit (2021-12-03)

Loblolly pine (Pinus taeda L.) is a predominant timber species native to the southeastern United States. Since 2016, the species has been experiencing needle defoliation and tree mortality. Symptoms appear as yellowing to ...

Impact of cogongrass (Imperata cylindrica) presence and management strategies on arthropod natural enemy populations in longleaf pine stands

Martin, Sallie (2012-04-09)

Cogongrass (Imperata cylindrica Beav.) is an aggressive, invasive weed that is threatening the integrity of longleaf pine (Pinus palustris Mill.) ecosystems in southeast Alabama. Various management strategies are implemented ...

Impact of Imperata cylindrica on Populations of Root-feeding Bark Beetle Populations and Factors Associated with Loblolly Pine Decline in a Pinus taeda Stand

Brunson, Ben (2013-11-25)

The non-native, invasive plant, cogongrass (Imperata cylindrica (L.) Beauv) is a threat to the diversity of native plant species of the southeastern United States. Another issue facing landowners of southeastern forests ...

Impact of Tree Inoculation by Leptographium terebrantis on Soil Microbial Communities in Commercial Loblolly Pine Stand

Duwadi, Shrijana (2019-04-17)

A variety of abiotic and biotic stressors, including root-feeding bark beetles and pathogenic ophiostomatoid fungi, are associated with root disease of Pinus spp. Our research goal was to analyze if a tree inoculation by ...

Influence of Leptographium terebrantis S.J. Barras and T.J. Perry on Pinus taeda L. physiology, growth and productivity

Mensah, John K (2020-10-19)

Loblolly pine (Pinus taeda L.) is the predominant tree species in forest plantations across the southeastern U.S., but over the past several decades, cases of declining loblolly pine have been reported in localized areas ...

Mapping Loblolly Pine Decline Hazard and Risk across the Southeastern United States

Meyerpeter, Matthew (2012-07-25)

Loblolly Pine Decline was first noted in 1959 in the Oakmulgee and Tuscaloosa Ranger Districts in the Talladega National Forest, located in the southeastern United States. This slow mortality is not new to the area, but ...
