However, the nature and magnitude of the changes that result from prescribed burning are still incompletely known, and this is especially true for the forests of the Ozarks of northern Arkansas. The overall objective of the research project described herein was to obtain the data necessary to develop a better understanding of these changes, particularly as they relate to the use of prescribed burning as a management technique in the Buffalo National River of north central Arkansas. Twenty 10 by 10 m plots (10 in burned areas and 10 in unburned areas) were established in each of five different study sites (for as total of 100 plots) strategically located to represent different sections of the Buffalo River (lower, middle and upper). Data on the composition and structure of all strata of vegetation, plant debris...

However, the nature and magnitude of the changes that result from prescribed burning are still incompletely known. In the present study, the effects of prescribed burning were assessed in five study areas located along the Buffalo National River. Data on the structure and composition of forest vegetation were collected from twenty10 by 10 m plots (10 in burned areas and 10 in unburned areas) in each study area. Statistically significant differences were noted between burned (first value) and unburned (second value) plots for percent grass cover (1.50 vs 0.75), tree volume (26.90 vs 16.80 m 3) and numbers of forbs (203 vs 136), seedlings (161 vs 95), saplings (156 vs 163), shrubs/vines (306 vs 257) and trees (2540 vs 4268) per hectare. Although fire has been reported to suppress the invasion of mesic species (beech and sugar maple) in oak-hickory forests, only one of the five study sites had enough beech saplings present to show that fire can significantly reduce the number of saplings of this species in the understory (12 vs 33). However, the overall results indicate that prescribed burning does not seem to have any readily apparent negative effects on forests if carried out in a proper manner. Jmp statistical software and chi-square were used to analyze data for the existence of significant differences between the burned and unburned sites. Site similarities and dissimilarities were also derived through a dendrogram.
