Ground-based measurements of carbon accumulation in wood and soil water withdrawal at the logged site in Tapajos National Forest, Para, Brazil. (A) Wood production versus tree height before (November 2000–September 2001, open squares) and after (October 2001–March 2004, solid circles) logging for 734 trees, normalized by total wood production. (B) Water withdrawal versus depth at the logged site measured during the 2002 dry season (August–November) in an intact area (open squares) and within a logging gap (filled circles), normalized by total column water withdrawal for the same period. In both panels, the hatched (shaded) region corresponds to increased (decreased) activity after logging.
