Understory-Overstory Relationships in Ponderosa Pine Forests, Black Hills, South Dakota

Abstract: Understory-overstory reiationships were examined over 7 different growing stock levels (GSLa) of 2 size dames (saplings, 8-10 cm d.b.h. and poles, 15-18 cm d.b.h.) of ponderosa pine (pinur pondaoso) in the Black Hiils, South Dakota. Generaiiy, production of graminoids, forbs, and shrubs ~88 similar between sapiing and pole stands. Trends among GSLS were also similar between these tree size classes. Graminoids and forbe were most abundant in clearcuts and the S ml/ha basai area. Intermediate amounts were produc… Show more

“…Our results are consistent with other overstory-understory studies in ponderosa pine forests and pine-oak woodlands that demonstrate that high overstory canopy cover results in low herbaceous production (Arnold 1950), and that rapid recovery of understory plant biomass can be obtained by basal area reduction (Thompson and Gartner 1971;Ffolliott and Clary 1982;Uresk and Severson 1989;McPherson and Weltzin 1998;Wienk et al 2004). Increased light availability, resulting from tree thinning, was likely the main factor stimulating increased herbaceous standing crop (McLaughlin 1978;Riegel et al 1995;Naumberg et al 2001), in addition to higher nitrogen and water availability (Riegel et al 1995;Kaye et al 2005).…”

“…Herbaceous fuels range from practically none in dense stands to as much as 0.5 tons/acre (1.1 t/ha) in open stands on productive sites. In the Black Hills of South Dakota, herbaceous fuel quantities in open stands of ponderosa pine averaged 440 lb/acre (490 kg/ha), which was six times greater than in closed stands (Uresk and Severson 1989). Herbaceous fuel quantities are typically about 400 lb/acre (448 kg/ha).…”
