In Brazil, pastures for cattle ranching are being established in areas that were previously forested. To investigate some consequences of this change in land use we measured fluxes of CO<sub>2</sub> and water vapour over a typical pasture, dominated by the introduced C-4 grass Brachiaria brizantha. In addition, we compared the CO<sub>2</sub>, water vapour fluxes and canopy stomatal conductances observed with those obtained simultaneously over a nearby undisturbed rain forest. Measurements were made near the end of the wet season under conditions of ample soil moisture. Leaf area index of the pasture was 3.9. The pasture had a lower canopy stomatal conductance than the forest (typically 0.2-0.3 mol m(-2) s(-1) versus 0.4-0.9 mol m(-2) s(-1) ...
