Even-Aged vs. Uneven-Aged Silviculture: Implications for Multifunctional Management of Southern Pine Ecosystems
AbstractWe evaluated even- and uneven-aged silvicultural options for slash pine (Pinus elliottii Engelm.) using empirical data and the Forest Vegetation Simulator (FVS) model. Data were collected from a mature unthinned slash pine plantation in a flatwoods site in Florida, and used to simulate six scenarios of even- and uneven-aged silvicultural regimes applied to slash pine stands, including a no-action option. These alternative silvicultural regimes were evaluated for multiple benefits including timber production, carbon storage and stand structural diversity over a period of 100 years. None of the silvicultural regimes maximized all the benefits. While even-aged management options were more efficient in total merchantable timber production (9.78 to 11.02 m3·ha−1·year−1) and overall carbon stocks (3.05 to 3.47 metric tons·ha−1·year−1), uneven-aged management options created overall more complex stand structure (Stand Structural Diversity (computed from Shannon’s Indices values) = 1.92) and maintained a steady flow of yields, particularly sawtimber (34.29 to 58.46 m3·ha−1 every 10 year) and aboveground carbon stocks (56.9 to 77.2 metric tons·ha−1). Optimal achievement of multiple benefits across the landscape, therefore, may require maintaining an assortment of management strategies. Both even- and uneven-aged management options have the potential to improve production and carbon storage of pine forests and are a substantial improvement over no action. View Full-Text
