Site productivity assessment for cherrybark oak on minor stream bottoms in Mississippi: a comparison of methods

A study was conducted to test the accuracy of two soil-based site quality estimation methods against actual site index values for cherrybark oak located on minor stream bottoms in Mississippi. At the same time, the potential effects of slight changes in topographic position on estimated site quality and observed soil characteristics were examined of the two soil-based methods, only one system provided accurate estimates of observed site index. However, both soil-based methods proved to be more sensitive than observed site index to changes in topographic position. Finally, the soil characteristics found to have the most potential influence on estimates of site quality for cherrybark oak were depth to mottling, topsoil depth, and soil texture
