A floral survey of cliff habitats along Bull Run at Manassas National Battlefield Park, Virginia, 2014
Isolated patches of native vegetation in human-modified landscapes are important reservoirs of biological diversity because they may be the only places in which rare or native species can persist. Manassas National Battlefield Park, Virginia, is an island embedded in a matrix of intensively modified lands; it is becoming increasingly isolated due...

Effects of mining-associated lead and zinc soil contamination on native floristic quality
We assessed the quality of plant communities across a range of lead (Pb) and zinc (Zn) soil concentrations at a variety of sites associated with Pb mining in southeast Missouri, USA. In a novel application, two standard floristic quality measures, Mean Coefficient of Conservatism (Mean C) and Floristic Quality Index (FQI), were examined in...
Struckhoff, Matthew A.; Stroh, Esther D.; Grabner, Keith W. Oak woodlands and forests fire consortium: A regional view of fire science sharing
The Joint Fire Science Program established 14 regional fire science knowledge exchange consortia to improve the delivery of fire science information and communication among fire managers and researchers. Consortia were developed regionally to ensure that fire science information is tailored to meet regional needs. In this paper, emphasis was...
Grabner, Keith W.; Stambaugh, Michael C.; Marschall, Joseph M.; Abadir, Erin R. Changes to oak woodland stand structure and ground flora composition caused by thinning and burning
Our objective was to quantify the cumulative effects of prescribed burning and thinning on forest stocking and species composition at a woodland restoration experiment site in the Ozark Highlands of Missouri. Our study used four treatments (burn, harvest, harvest and burn, control) on three slope position and aspect combinations (south, north,...
Kinkead, Carter O.; Kabrick, John M.; Stambaugh, Michael C.; Grabner, Keith W. Genesis of an oak-fire science consortium
With respect to fire management and practices, one of the most overlooked regions lies in the middle of the country. In this region there is a critical need for both recognition of fire’s importance and sharing of fire information and expertise. Recently we proposed and were awarded funding by the Joint Fire Science Program to initiate the...

Vegetation communities at Big Muddy National Fish and Wildlife Refuge, Missouri
New and existing data were used to describe and map vegetation communities at Big Muddy National Fish and Wildlife Refuge. Existing data had been gathered during the growing seasons of 2002, 2003, and 2004. New data were collected in 2007 to describe previously unsampled communities and communities within which insufficient data had been collected...

Mapping vegetation communities in Ozark National Scenic Riverways: final technical report to the National Park Service
Vegetation communities were mapped at two levels in Ozark National Scenic Riverways (ONSR) usign a hybrid combination of statistical methods and photointerpretation. The primary map includes 49 cover classes, including 24 cleasses that relate to vegetation associations currenly described by the United States National Vegetation Classification...

Grabner, Keith W.; Struckhoff, Matthew; Buhl, Deborah A. An updated rate-of-spread clock
Several years ago, Blank and Simard (1983) described an electronic timer, frequently referred to as a rate-of-spread (ROS) clock—a relatively simple instrument used in measuring fire spread. Although other techniques for measuring rate of spread are available (such as data loggers), the basic ROS clock remains a valuable and relatively inexpensive...
