Short summary

Eddy covariance and biometric measurements were used to contrast the effects of defoliation by gypsy moth and prescribed fire on net CO2 exchange (NEE) and ecosystem water use efficiency (WUEe) in three forests in the New Jersey Pinelands, USA. Defoliation reduced long-term NEE and WUEe, while prescribed burning had little effect. Our results suggest that WUEe following disturbance is dependent on its impact on the N status of canopy foliage, in addition to time since disturbance.
