    Analysis of the Cloquet Forestry Center continuous forest inventory 1959-1990.
    (University of Minnesota, 1994-12) Tuhus, Erik H.; Walters, David K.; Ek, Alan R.
    This report describes procedures, analysis, and results from a study of the Cloquet Forestry Center continuous forest inventory (CFI). The CFI on the property was established in 1959 and plots have since been measured five additional times. Summary tables are presented for individual covertypes and for covertype aggregates, for all measurement years. Trends in covertype acreage, growing stock, age class, and size class distribution for the forest over the 31-year period are also discussed. This study was conducted using an Rbase 4.5 relational database on a PC. A description of Rbase command files developed and used in the study and necessary editing and changes made to the database are included as appendices.
