The effect of season and frequency of burning and mechanical vegetation treatments on herbaceous species composition in pine-hardwood stands of coastal South Carolina. (South Carolina Junior Academy Of Sciences Abstracts).

Fire is known to affect the soil and vegetation in forested ecosystems throughout the United States. This study was conducted to determine the effect of prescribed forest fires that occurred during different seasons and frequencies in forests of herbaceous species to examine composition and cover in pine-hardwood stands located in coastal South Carolina. Herbaceous vegetation species were sampled with fixed-area quadrants in three trials containing six vegetation treatments. Forbs (i.e. St. John's wort, Blackberry, Violet) and grasses (i.e. Johnson grass, Cana) were the most common taxa as estimated by percent cover. The percent cover distribution for the mechanical/chemical treatments and the annual summer treatments were significantly different than the controls in most trials for all taxa. Significant percent cover differences due to seasonal burning (summer versus winter) were noticed in both plots (annual versus periodic). Significant percent cover differences due to the frequency of burning were noticed in all three trials for both winter (trial one) and summer burning (trials two and three). This study demonstrated the effects of season and frequency of prescribed burning on the percent cover distribution of herbaceous vegetation.
