A Vegetation Classification of Fire-Dependent Pinelands of Florida

Author : Susan C. Carr

Additional Authors : Kevin M. Robertson, Robert K. Peet

ABSTRACT Prior to European settlement, the portion of north and central Florida corresponding to the historic range of longleaf pine (Pinus palustris) was dominated by firedependent, herbaceous and open woodland plant communities. Economic development coupled with fire suppression lead to a drastic decline in the abundance, contiguity and integrity of these natural communities. We present …


Death and Decline of a Rare Cactus in Florida

Author : Peter Stiling

ABSTRACT Conseola corallicola is a rare cactus that is known from just two islands in Florida, Little Torch Key and Swan Key. The appearance of the cactus-eating moth, Cactoblastis cactorum, in the 1980s, threatened its survival. Outplantings at various locations were made in the 1990s and early in the 21st century to try to boost …


Habitat and Search Criteria of the Rare Sandhills Lily, Lilium pyrophilum M. W. Skinner and Sorrie

Author : Cheryl Gregory

Additional Authors : Richard Braham Gary Blank Jon Stucky

ABSTRACT Thirty populations of Sandhills lily (Lilium pyrophilum) in North Carolina and Virginia were studied to understand the habitat requirements and develop search criteria to find new populations. In each population a study plot containing lily individuals was compared with a nearby plot lacking the lily. Lilium pyrophilumhabitat occurred on floodplains and adjacent side slopes …


Twenty-five Years of Succession in the Spruce-Fir Forest on Mount Rogers in Southwestern Virginia

Author : Harold S. Adams

Additional Authors : Steven L. Stephenson

ABSTRACT Four study areas located within the Fraser fir (Abies fraseri)-red spruce (Picea rubens) forest on the summit of Mount Rogers in southwestern Virginia sampled originally in July 1982 were resampled during June 2007. Mount Rogers is the northernmost locality for Fraser fir, a species that has suffered serious damage over the past half century …


Biological Diversity Associated with Bigtooth Aspen Patches in a Mixed Oak Landscape

Author : Audrey K. Larrimer

Additional Authors : Brian C. McCarthy

ABSTRACT This study evaluated the ability of bigtooth aspen (Populus grandidentata Michx.) patches to contribute to the understory diversity of southeastern Ohio’s mixed oak forests by providing unique microenvironments embedded within the larger mixed vegetation matrix. Twenty bigtooth aspen patches and adjacent mixed oak forest were selected for study. Microenvironmental parameters were assessed in both …


A Calculation of Expected Plant Frequency

Author : Steven R. Helm

ABSTRACT A calculation is presented that converts plant frequency per plot size sampled to expected frequency per any plot size of interest so as to compare studies that used different plot sizes or to assess degrees of spatial randomness in individual studies that used multiple plot sizes. Expected frequency is exponentially related to measured frequency, …


Suther Prairie: Vascular Flora, Species Richness, and Edaphic Factors

Author : Robert D. Tompkins

Additional Authors : Catherine M. Luckenbaugh, William C. Stringer, Keith H. Richardson Elena A. Mikhailova William C. Bridges, Jr.

ABSTRACT Piedmont prairie communities of the southeastern United States were common prior to European settlement. Suther Prairie in Cabarrus County, North Carolina is among the best-known examples of such an ecosystem. This study provides a complete floristic list of species observed at the site from1997–2007. Sampling over the 10 yr period included fixed transects and …


Vascular Plants of an Abandoned Limestone Quarry in Garrard County, Kentucky

Author : Ralph L. Thompson

Additional Authors : Stephanie R. Green

ABSTRACT A descriptive survey of the vascular plants was conducted on the Camp Nelson Quarry, a 2.3 ha limestone quarry, abandoned since 1991 in Garrard County, Kentucky. Collections made from this site during 1996, 1997, 2000, 2003, and 2004 resulted in an annotated plant list of 209 species in 155 genera from 61 families. The …

Author : Joshua A. Wibbenmeyer

Additional Authors : Allan J. Bornstein Bob Gillespie

ABSTRACT This study was undertaken to document the vascular plant species of Sand Prairie Conservation Area, an 80 hectare site located at roughly 37u059N; 89u309W in Scott County, Missouri, during the growing seasons of 2007 and 2008. A total of 220 vascular plant taxa were collected from the Conservation Area: 55 Monocots, 162 Dicots, one …
