Oldest Botanical Journal in the Western Hemisphere Age and distribution of an evergreen clonal shrub in the Coweeta Basin: Rhododendron maximum L

Inhibition of Seedling Survival under Rhododendronmaximum

In the southern Appalachian mountains Rhododendron maximum L. (R.m.) is the dominant subcanopy evergreen species. Approximately 30 million hectares of the southern Appalachian mountains are occupied by R.m. This subcanopy evergreen shrub forms extensive thickets, near streams and on north slopes, reaching a height of 3-6 m. On north-facing slopes these thickets form a mosaic of -40% cover. Ther...

Evergreen Understory Dynamics in Coweeta Forest, North Carolina

A number of studies have elucidated the distributional patterns of various components of Southern Appalachian forests. The evergreen understory here is composed largely of a dominant ericaceous shiub, Rhododendron maximum L., which is believed to be expanding and inhibiting the development of other species with consequent impacts on overall forest structure and composition. We use a GIS and log...

Terrain and Landform Influence on Tsuga canadensis (L.) Carrière (Eastern Hemlock) Distribution in the Southern Appalachian Mountains

We examined the relationships between hemlock distribution and abundance and terrain attributes for the Coweeta Basin in the southern Appalachian Mountains. Field measurements were combined with GIS mapping methods to develop predictive models of abundance and distribution of Tsuga canadensis (L.) Carrière (eastern hemlock) and evaluate the co-occurrence of Rhododendron maximum L. (rosebay) and...

A Total Ratio of Vegetation Index (TRVI) for Shrubs Sparse Cover Delineating in Open Woodland

Persian juniper and Pistachio are grown in low density in the rangelands of North-East of Iran. These rangelands are populated by evergreen conifers, which are widespread and present at low-density and sparse shrub of pistachio in Iran, that are not only environmentally but also genetically essential as seed sources for pistachio improvement in orchards. Rangelands offer excellent opportunities...
