Germination and early growth of Ailanthus and
tulip poplar in three levels of forest disturbance
- Nathan L. Kota, Rick E. Landenberger, J. McGraw
- Biology
- Biological Invasions
- 1 March 2007
Increasing rates of forest disturbance may provide greater opportunity for invasion of nonnative species, thereby altering the successional trajectory of native plant communities. In the eastern… Expand
Seed dispersal of the non-native invasive tree Ailanthus altissima into contrasting environments
- Rick E. Landenberger, Nathan L. Kota, J. McGraw
- Biology
- Plant Ecology
- 14 August 2007
Ailanthus altissima has a long history of invasion in urban areas and is currently spreading into suburban and rural areas in the eastern U.S. The objectives of our study were to (1) determine… Expand
Seasonal Trends in Separability of Leaf Reflectance Spectra for Ailanthus altissima and Four Other Tree Species
- A. Burkholder, T. A. Warner, M. Culp, Rick E. Landenberger
- Geography, Environmental Science
- 1 August 2011
The separability of Ailanthus altissima (tree of heaven) from four native species was investigated using spectral reflectance measurements (350 to 2,500 nm) of leaves collected from 13 May through 24… Expand
Seed-bank characteristics in mixed-mesophytic forest clearcuts and edges: Does "edge effect" extend to the seed bank?
- Rick E. Landenberger, J. McGraw
- Biology
- 1 July 2004
Little is known about the seed banks of mixed-mesophytic forest clearcuts or their associated forest edges. Seed banks were described and compared to better understand how seed density, species… Expand
Spatial patterns of female Ailanthus altissima across an urban-to-rural land use gradient

- Geography
- Urban Ecosystems
- 20 March 2009
Ailanthus altissima is an invasive, dioecious deciduous tree common at the interface between urban and rural areas in the mid-Atlantic region, U.S.A. To examine spatial patterns of abundance and… Expand
Eupatorium rugosum (Asteraceae) flowering as an indicator of edge effect from clearcutting in mixed-mesophytic forest
- Rick E. Landenberger, D. Ostergren
- Biology
- 2002
Abstract We analyzed flowering of white snakeroot (Eupatorium rugosum) as an indicator of edge effect from recent silvicultural clearcutting in mixed-mesophytic forest in northcentral West Virginia.… Expand

Segmentation and classification of high resolution imagery for mapping individual species in a closed canopy, deciduous forest
- T. A. Warner, J. McGraw, Rick E. Landenberger
- Mathematics
- 1 June 2006
In this paper we investigate the use of a shadow-based delineation program for identifying segments in imagery of a closed canopy, deciduous forest, in West Virginia, USA, as a way to reduce the… Expand
