The soils inventory of the AOSERP study area using the ecological approach to land classification was continued during 1979. All field checking and soil sampling was completed during the 1979 summer field season. Samples were taken from eight mineral and eight organic soil profiles. In addition, samples of parent materials from eight mineral soil sites were taken for analysis. Of the samples taken during 1978, laboratory analyses have been completed on 30 soil profiles and are reported in the Appendix. Analyses of samples from 34 more profiles taken during 1978 are being completed with those taken during 1979 and results will be reported at a later date. Ten soil maps on 1:50,000 National Topographic Series or Forest Cover Series bases were produced and submitted to AOSERP management. The legend remains the same as that published in the 1979 interim report.
