Response of a Native Perennial Grass Stand to Disturbance in California’s Coast Range Grassland

To assess the potential for enhancing an existing stand of native perennial grasses on a California Coast Range Grassland site, we experimentally manipulated the seasonal timing and presence of grazing for 3 years (1994 through 1996) and of autumn burning for 2 years (1994 and 1995) and measured species cover for 6 years (1993 through 1998). We subjected the species matrix to classification (TW...

Rhizodeposition stimulated by elevated CO2 in a semiarid grassland

• Rhizodeposition, or the addition of C from roots to soil C pools, is expected to increase if net primary production is stimulated and some excess C is allocated below-ground. We investigated the effects of 5 yrs of elevated CO2 on belowground C dynamics in a native, C3–C4 grassland ecosystem in Colorado, USA. • Cylinder harvests following each growing season and monolith excavation at the end...
