    Are we losing the hardwoods that turkeys depend on? | Wild Turkey Science #603

    We're bringing back the episode where we dig into decades-old crop-content studies to quantify exactly how much of a turkey's diet is acorns, and what the trends in declining oak forests mean for the future of wild turkeys.   Resources: Alexander et al.

    Timber Cruising and Forest Inventory with Dr. Joshua Granger | Timber University #600

    Forest inventory and timber cruising provide the information landowners and foresters need to understand what is growing on a property, how much timber is present, and how that timber should be managed or valued. In this episode of Timber University, Dr. Josh Granger from Mississippi State University joins us to discuss the different methods used to measure forests and why a well-designed inventory can be one of the most important investments a forest landowner makes. Dr. Granger is an Associate Professor in Mississippi State University's Department of Forestry, where he teaches dendrology, forest measurements, and forest description and analysis. His work helps students develop the practical skills needed to identify trees, measure forest resources, design timber cruises, and use inventory data to support forest management decisions. In this conversation, we discuss why the purpose of an inventory should determine how it is designed. Dr. Granger explains the differences among fixed-area plots, prism or variable-radius sampling, strip cruises, nested plots, and 100-percent inventories. He also discusses why no single method is best for every situation and how foresters often combine methods to efficiently collect the information needed. We also explain basal area, trees per acre, total height, merchantable height, and the level of precision needed for different types of forestry work. The conversation explores why a diameter measurement to the nearest tenth of an inch may be useful for research, growth monitoring, or carbon accounting, while broader diameter classes may be adequate for some operational timber cruises. The episode also emphasizes the financial importance of obtaining a reliable inventory before buying or selling timber. Without an independent estimate of timber volume, quality, and product composition, landowners may have little basis for determining whether an offer reflects the true value of their timber. Forest inventories can also support property appraisals, timber-basis calculations, casualty-loss documentation, carbon projects, wildlife management, invasive-species monitoring, and long-term assessments of forest growth and condition. This episode is a useful listen for forest landowners, consulting foresters, forestry students, timber buyers, land managers, appraisers, extension professionals, and anyone interested in understanding how forests are measured and valued.

    Impacts of vegetation structure on hen survival and nest success | Wild Turkey Science #599
