Résumé :	Data from 122 northeastern Ontario plots were used to develop composite siteproductivity functions for black spruce (Picea mariana [Mill.] B.S.P.). A logistic model produced the best fit to the data. The resulting equations produce sets of polymorphic siteproductivity curves with subsets of three curves, one for each of Ontario's Forest Ecosystem Classification Operational Groups (FEC OGs) 11, 12 and 14. For direct estimates of site productivity, site index was expressed as a function of stand height, age and FEC OG by employing the reciprocal of the logistic model. Application of the resulting equations and tables is demonstrated in an example. The procedures employed may be used to develop ecologically based site-productivity functions for other areas.
