| A Review of the “Pull-Up” and “Leave-Down” Methods of Planting Loblolly Pine | Vol. 51, Issue 1 | Article provides a review of the research and science behind two approaches to planting loblolly pine seedlings – essentially a comparison of planting depth vs. root straightening priorities. Shallow planting regardless of taproot form can kill seedlings. A seedling that has a bent taproot but is planted deeply will have a higher probability of survival than a shallow planted seedling with a straight taproot. David B. South, Professor, School of Forestry and Wildlife Sciences and Alabama Agricultural Experiment Station, Auburn University, AL.

| Best Management Practices (BMPs) for the Sustainable Harvesting of Biomass | | In the 2023 General Assembly session, HB2026 and SB1231 amended the Virginia Clean Economy Act (VCEA) to enable woody biomass to continue to be used as a source of electric power generation in Virginia and for specific biomass energy facilities to be included as eligible sources in the renewable energy standard. This document outlines the best management practices enforcement process and guidance for the sustainable harvesting of biomass for electric generation, as well as information gathered for the carbon LCA in 2023.

The results of this study suggest that no single planting density will be optimal for all management objectives. Ralph L. Amateis and Harold E. Burkhart.
