Seeing past the green: Structure, composition, and biomass differences in high graded and silviculture-managed forests of similar stand density
Forests of the eastern United States (US) mostly comprise a mix of stands managed following silvicultural principles and stands managed with exploitative timber harvesting practices. These stands can have similar stand densities (e.g., basal area per hectare) but vary vastly in structure, composition, and biomass and carbon storage. High grading, a prevalent exploitative timber harvesting practice in the eastern US, is of particular concern because it can negatively affect future forest health and productivity. This study quantifies differences in forest structure, composition, and biomass and carbon storage between high graded stands and stands that received a seed/establishment cut of a uniform shelterwood regeneration sequence treatment, which is a comparable and well-established silvicultural method used to regenerate mixed-oak forests. It focuses on mixed-oak forests (mixed-Quercus), where the effects of high grading have been understudied, and uses a sample with broader spatial coverage than previous studies. The sample comprised nine stands that were known to have been high graded 8–15 years ago and nine stands that received the seed/establishment cut of a uniform shelterwood regeneration sequence. Stand were systematically sampled using fixed-area plots. Field measurements were collected and used to calculate metrics describing forest structure and function. The structure of high graded stands was characterized by a higher proportion of trees with poor health and/or form compared to shelterwood stands, with 18.3 % less acceptable growing stock and trees with lower crown compaction. Diameter distributions of high graded stands were characterized by numerous small trees and few large-diameter trees. Spatial variability of overstory trees was contingent on the tree size range evaluated, with a larger variability of sawtimber-sized trees (trees ≥ 29.2 cm in diameter at breast height) in high graded stands. High graded stands also had 2.2 times fewer oak trees (Quercus spp.) in the overstory canopy, 17,897 fewer seedlings per hectare (ha), and 45 Mg/ha less biomass than shelterwood stands. These results indicate that high grading generally degrades mixed-oak forests and impairs their long-term capacity to supply vital ecosystem services such as habitat for specific wildlife species, carbon storage, and high-quality wood products.

Purdue Extension-Forestry and Natural Resources
Purdue Extension-Forestry and Natural Resources is a part of a larger group, the Cooperative Extension Service (CES), one of the nation’s largest and best-researched providers of science-based information and education. The Purdue Extension-Forestry and Natural Resources is a great resource and reaches out not only to the state of Indiana but worldwide. We provide resources for aquaculture, fish management, urban and forestry management, natural resource planning, wildlife, and sustainable biomaterials. We encourage you to browse, download free publications, view workshops on the Purdue Extension-FNR Calendar, ask an expert, view Purdue Extension Annual Report and visit other sites that have been added as helpful links.

The Conservation Foundation
The support of more than 5,000 members and 500 volunteers helps us carry out our mission to improve the health of our communities by preserving and restoring open space and natural lands, protecting rivers and watersheds, and promoting stewardship of our environment in northeastern Illinois. We focus our work in DuPage, Kane, Kendall, and Will Counties where we have helped preserve more than 35,000 acres of open space, and we also go where we are needed in LaSalle, DeKalb, and Grundy Counties.
New analysis highlights conservation challenges and opportunities on Western public lands
Recently published science applies remote-sensing tools to BLM-managed rangelands and provides an unprecedented record of how the vegetation across this enormous area has changed over the past 30 years.
The Conservation Foundation Private Landowners
The connections between people and land are countless. Land can provide a spiritual sense of place, happy memories of times past, and hope for future generations’ connections with the land around them. Some of our greatest accomplishments have been tied to preserving not only the land, but the legacies that go with it. There are many reasons why someone may want to ensure the long-term protection of a piece of land or restore its ecological health and many ways to accomplish it. Check out the many options that are available for you to protect or restore your special place.
