Handbook for inventorying surface fuels and biomass in the Interior West

“…This approach requires a tally of number of stems by stem diameter on plots of known size. Another method relies on the relationships between biomass, canopy area, and canopy volume as described for semidesert shrubs in New Mexico (Ludwig and others 1975), sagebrush (Artemisia tridentata) (Rittenhouse and Sneva 1977), and low shrubs in California (Bently and others 1970). This method requires measurements of crown diameters and shrub height.…”

Phytovolume, phytomasse et relations structurales chez quelques arbustes méditerranéens

“…D'autres, enfin, assimilent le volume à celui d'un prisme droit à section elliptique englobant la plante (Rittenhouse et Sneva, 1977;Uresk et al, 1977;Hughes et al, 1987) ou à celui d'un prisme droit dont la section est un polygone quelconque, en fait la projection au sol de la couronne (Burgan et Rothermel, 1984).…”

Plant and Soil Consequences of Shrub Management in a Big Sagebrush-Dominated Rangeland Ecosystem

“…Though we did not directly quantify pools of C in decaying woody tissues, using developed relationships from Rittenhouse and Sneva (1977) for predicting aboveground biomass production of plants from height (25 cm from Figure 1C) and canopy width (i.e., intercept length from Figure 2H, 20 cm), estimated annual aboveground biomass production (photosynthetic and woody total) for Wyoming big sagebrush plants at the LES control area would be 19.8 g plant -1 . Multiplying this by the difference between live and dead plant densities (1.5 plants m -2 , Figure 1C), we can estimate that the lost pool of annual aboveground C associated with plants selectively thinned by the herbicide in 1997 would be 0.13 Mg C ha -1 yr -1 (15,000 plants ha -1 × 19.8 g plant -1 × 44% carbon in biomass).…”
