File text/texmacs Decision Support Tools to Inform the Rehabilitation and Management of High Graded Forests
by Josselyn Lucas — published Feb 15, 2023 — filed under: , , , , , ,
Abstract 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.

File Seeing past the green: Structure, composition, and biomass differences in high graded and silviculture-managed forests of similar stand density
by Josselyn Lucas — published Feb 15, 2023 — last modified Feb 24, 2023 02:45 PM — filed under: , , , , , , , , , , ,
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.

File ECMAScript program Conservation Choices for Wildlife: Golden-winged Warbler and Other Forest-dependent Species
by Tab Manager — published Jun 06, 2019 — last modified May 29, 2025 06:03 PM — filed under: , , , , , , ,
This guide outlines seven key conservation practices recommended to forest landowners who want to sustainably manage forests to benefit wildlife and forest health. USDA’s Natural Resources Conservation Service (NRCS) and conservation partners work with forest landowners to plan and implement these practices that benefit a variety of species, including the golden-winged warbler. This assistance includes the development of a custom forest management plan as well as financial support to help cover part of the costs of implementing the practices. Technical and financial assistance are available through the Farm Bill, the largest source of federal funding for private lands conservation.

File Golden-winged Warbler Non-breeding Season Conservation Plan
by Kristin Bomboy — published Mar 17, 2021 — last modified Jun 25, 2023 10:40 PM — filed under: , ,
The Golden-winged Warbler Non-breeding Season Conservation Plan (Chapter 4 of the Goldenwinged Warbler Conservation Plan) describes the non-breeding ecology of the Golden-winged Warbler and proposes concrete actions to maintain habitat throughout its stationary nonbreeding range (hereafter winter range). The plan is intended for use by conservation practitioners, land managers, and governmental agencies both in North America and Latin America. This plan provides guidance on where conservation investment in Latin America will have the greatest impact on Golden-winged Warbler habitat and recommends conservation actions to address the specific threats to habitat retention in the winter range. This plan is also intended for use at the country level for all Latin American countries within the Golden-winged Warbler winter range. For each country, this plan prioritizes areas where conservation action should begin immediately, defines five-year conservation goals, and proposes a conservation strategy to meet those goals by the year 2020.
