Summary
On North American prairies, growing-season wildfires are relatively frequent. There is interest in using prescribed growing-season fires in management, but there is a lack of knowledge as to effects on vegetation, especially of mid-successional tallgrass prairie. A study was undertaken in Oklahoma (south-central USA) comparing vegetation composition and production on two mid-successional stage sites in response to late growing-season fire at different frequencies.
The experiment was conducted at the Samuel Roberts Noble Foundation (Love County) at two prairie sites: a ‘loamy’ (1.2 m deep loam soil) and a ‘very shallow’ (stony soil to 25 cm depth over limestone) site. Both were dominated by early- and mid-successional native grasses. Four burn treatments (no burn, or 1, 2, or 3 burns in 5 years) were applied to 10 x 20 m plots (3 replicates of each) at each site; burn dates:1990 (4-5 September), 1991 (3 October) and 1993 (9 August).
