Effect of fire on fine root density in red shank (Adenostoma sparsifolium Torr.) chaparral

  • J. Kummerow

In December 1981 a 2 ha site of 54-yr southern California chaparral was burned. A frequent species on this site wasAdenostoma sparsifolium. This shrub regenerates after fire with stump sprouting. The total fine root (diam. <1.0 mm) density of the matureA. sparsifolium stand was estimated to be 50–100 g m−2. This value was obtained in late summer. At this time fine root density in chaparral is at its lowest. In the growing season after the burn no signs for reduced fine root density were detected. Indeed, indications for a fire-enchanced flush of fine root growth were found.
