| Abstract: | The resprouting ability following cutting of the chaparral shrub Baccharis pilularis ssp. consanguinea (DC) C. B. Wolf was investigated following the felling of individuals of various ages. Numbers of resprouts and resprout biomass were low in 1-yr-old shrubs, increased to a maximum in shrubs 3–4 yr old, and declined to zero in shrubs <8 yr old. Numbers of leaves produced were also lower in 1-yr-old shrubs. The results are interpreted on the basis of the internal origin of resprout buds and the increasing extent of the shrub's root system as it matures. |
