Abstract

Trends in productivity and mineral content of herbaceous vegetation
in Ponderosa pine and montane grassland over a 4-year
period are reported. Dry matter production on burned areas was
1.4, 1.3, 2.2 and 1.6 times that on unburned sites in the four
successive years following the fire. Annual forbs and annual
grasses contributed 56% of total dry matter the first year following
fire. Perennial forbs contributed 40, 75, 75, and 77% of dry matter
on the burned sites in successive years following the fire, compared
with 66% on the unburned site. Herbage mineral concentrations
did not change appreciably following fire, although low values for
nitrogen and potassium were apparent in the first year.
