Preliminary Evidence that Intraspecific Competition Increases Size of Restoration-Planted Pitch and Shortleaf Pines in a Mixed-Hardwood Clearcut in the Southern Appalachians

Autor: W. Henry McNab

Publikováno v: Forest Science. 67:374-379

Oak-pine (Quercus L. - Pinus L.) forest communities on low ridges in the southern Appalachian Mountains are losing diversity as mature pitch (P. rigida Mill.) and shortleaf (P. echinata Mill.) pines die and do not regenerate under a hardwood canopy.

Effect of gap size on composition and structure of regeneration 19 years after harvest in a southeastern bottomland forest, USA

Autor: John I. Blake, Stanley J. Zarnoch, John C. Kilgo, W. Henry McNab

Publikováno v: Canadian Journal of Forest Research. 51:380-392

Following timber harvests in bottomland mixed-oak (Quercus L.) stands, desirable oak advance regeneration can be overgrown by shade-intolerant pioneer species. We investigated the effects of group selection opening size on composition of tree regener

Composition and Structure of Reproduction in Group Selection Openings after 20 Years in a Southern Appalachian Mixed-Hardwood Forest

Autor: Theodore M Oprean, W. Henry McNab

Publikováno v: Forest Science. 67:335-346

Following harvests by even-aged methods in mixed-hardwood forests, desirable oak (Quercus spp. L.) reproduction can be quickly overtopped by shade-intolerant pioneer species. In a long-term, operational-scale study of uneven-aged management by group

A vegetative index of stand productivity based on tree inventory for predicting oak site index in the Central Hardwood Region

Autor: W. Henry McNab, Tara L. Keyser

Publikováno v: Canadian Journal of Forest Research. 50:760-773

Models for prediction of site index (SI) typically include only abiotic causal variables (e.g., soil) and lack biotic response variables (e.g., vegetation), which could exhibit greater sensitivity to important environmental factors affecting tree hei

American Chestnut Growth and Survival Five Years after Planting in Two Silvicultural Treatments in the Southern Appalachians, USA

Autor: Stanley Zarnoch, David Loftis, Henry McNab, Stacy Clark

Publikováno v: Forests, Vol 3, Iss 4, Pp 1017-1033 (2012)

The ability to restore American chestnut (Castanea dentata) through the planting of blight-resistant (Cryphonectria parasitica) trees is currently being tested. Forest-based research on the species’ silvicultural requirements and chestnut blight de

Survivorship, attained diameter, height and volume of three Paulownia species after 9 years in the southern Appalachians, USA

Autor: Stanley J. Zarnoch, Erik C. Berg, W. Henry McNab

Publikováno v: Journal of Forestry Research. 31:2181-2191

Little is known of the tree and stand dynamics of varied species of planted Paulownia left unmanaged until harvest in the southeastern United States. We sought to remedy this lack of information needed by land managers to make informed decisions by i

Season of burn effects on vegetation structure and composition in oak-dominated Appalachian hardwood forests

Autor: Cathryn H. Greenberg, Tara L. Keyser, W. Henry McNab

Publikováno v: Forest Ecology and Management. 433:441-452

Previous research indicates that low-intensity single or multiple prescribed burns in oak-dominated upland hardwood forest do not substantially change stand structure or species composition of the arborescent regeneration layer, leading managers and

Twenty-year survivorship of tree seedlings in wind-created gaps in an upland hardwood forest in the eastern US

Autor: W. Henry McNab, Erik C. Berg, Stanley J. Zarnoch

Publikováno v: New Forests. 50:323-344

Wind is a common canopy disturbance in the upland oak (Quercus)- and hickory (Carya)-dominated stands of the Central Hardwood Region of the eastern US. Canopy openings range from small gaps, resulting from windthrow of single dominant trees, to occas

Reptile and amphibian response to season of burn in an upland hardwood forest

Autor: Cathryn H. Greenberg, Tara L. Keyser, Patrick Scott, J. K. Bush, Christopher E. Moorman, W. Henry McNab, Tyler Seiboldt

Publikováno v: Forest Ecology and Management. 409:808-816

Growing-season burns are increasingly used in upland hardwood forest for multiple forest management goals. Many species of reptiles and amphibians are ground-dwelling, potentially increasing their vulnerability to prescribed fire, especially during t
