A survey to evaluate Suillus luteus productivity in ponderosa pine plantations under different sites conditions and management practices was carried out, in order to develop recommendations regarding site selection and forest management options to maximize fructification. Preliminary results are presented from autumn 2005 (the survey will continue for at least two more seasons). Differences in sporocarp production were detected, with values between 0 to 14.03 Kg dry weight per ha per season. Plantations with higher productivity were associated with abundant herb cover and scarce needle depth, while plantations with lowest productivity were associated with sandy soils with little shrubs cover or with not pruned stands with abundant needle cover  of 7-8 cm depth.
