Abstract

Arctostaphylos pungens HBK is a dominant species with increasing abundance and distribution in chaparral ecosystems as a result of range management and, possibly, changes in climate. The value of this species for carbon (C) sequestration is unknown, and the standard 50% C out of total tree biomass is used as an approximate value. In this study, we aim to determine the C concentration of the primary components of A. pungens. The total C expressed as a percentage of biomass was determined with a Solids TOC Analyzer. We found the C concentration to vary among components. Leaves exhibited the highest C concentration (51.70%). Roots (46.11%), stems (47.30%), fruits (47.89%) and twigs (48.40%) had similar C concentration. These results provided superior estimates of C concentration, and reliable information concerning the potential use of A. pungens in climate-change mitigation programs.
