This study aims to analyze farmers’ preference for watershed ecosystem services and their willingness to contribute labor for the ongoing natural resource rehabilitation interventions in East and West Belesa Districts, Amhara region. The study assesses framers’ perception and intervention on natural resource rehabilitation activities, examine the mean willingness to contribute family labor required for public watershed activities and identify determinants of household preference for watershed ecosystem services. From the two districts a total 501 households were selected by using multi-stage sampling technique. The collected data was analyzed using descriptive and econometrics model. In the econometric part, mixed logit model has used to analyze the preference of watershed ecosystem services and mean willingness to contribute family labor. The descriptive result showed that farmers have positive attitude for improving the watershed ecosystem service through soil and water conservation, area enclosure, a forestation and reforestation natural resource management intervention methods. The mixed logit result revealed preference heterogeneity in attributes of watershed ecosystem services like improve soil moisture and fertility for cultivation, stabilize spring water flow, reduce soil erosion and increase crop productivity. Besides, preference of farmers for watershed ecosystem services is governed by the interaction of their socioeconomic setting and attitudinal backgrounds. For instance, the interaction between increased soil moisture and fertility for cultivation with household family size was positive and statistically significant. In addition, the interaction between reduced soil erosion with landholding was negative and statistically significant. The mean willingness to labor contribution result from the mixed logit revealed that the sampled households are willing to contribute for livestock fodder availability 9.5 labors per year for stabilizing spring water flow 9.7 labors per year for reduced soil erosion 1.74 labors per year and increase crop productivity 1.19 labor per year respectively. Key words: willingness to labor contribute, watershed ecosystem services, choice experimental model
