Numerous forests in the eastern United States have been degraded due to past exploitative timber 
harvesting known as high grading. High graded forest stands may not improve without active re- 
habilitation and may require targeted silvicultural treatments. This study focuses on high graded 
mixed-oak (mixed-Quercus spp.) stands and aims to develop a model that can identify past high 
grading and to determine modifications that may improve forest management recommendations provided 
by the prominent decision support tool, SILVAH. We present a model that uses standard forest 
inventory measurements and does not require knowledge of preharvest stand conditions to predict 
with moderate to high accuracy whether a stand was high graded, which could be par- ticularly 
useful for nonindustrial private forests. Results indicate that modifications to SILVAH may be 
necessary to improve its utility for prescribing silvicultural treatments in high graded stands.
Study  Implications: High graded forest stands are often not readily apparent and likely require 
specific forest management practices. We present a tool that uses standard forest inventory meas- 
urements to predict past high grading, which can be used to inform and prioritize forest manage- 
ment decisions. We also present suggested modifications to the prominent decision support tool, 
SILVAH, that may improve its ability to prescribe optimal silvicultural treatments for high graded 
stands. Results from this study provide forestry professionals/landowners working in the mixed- oak 
forests of the northeastern United States with tools to inform forest management decisions
that aim to return degraded stands to healthier and more productive states.
