DescriptionNo single set of site-index curves can be uniformly applied to young longleaf pine plantations without a sacrifice in reliability. A recent study using plantation remeasurement data indicated that planting-site condition (old fields and mechanically prepared or unprepared cutover forest sites) has a major impact on early plantation height growth. Stand density (surviving trees per acre) also affected form of height-over-age curves. On both prepared and unprepared forest sites, site quality affected curve form, so polymorphic site-index curves resulted for these two conditions. Longleaf pine plantation site-index curves for these three planting-site conditions were derived from 660 plots remeasured through ages 15 to 17 or 20 to 22 years. Modification of the curves may be necessary as more data become available.
