Abstract We present an optimal control model to simultaneously determine the planting density, thinning schedules, harvest age, and revenues of even-aged longleaf pine ( Pinus palustris Mill) stand, iconic species in Southeastern United States. assume that forest stand is managed for timber production carbon sequestration under different site indexes—a measurement potential productivity. Our si...

Mixed-species growth models are needed as a synthesis of ecological knowledge and for guiding forest management. Individual-tree models have been commonly used, but the difficulties of reliably scaling from the individual to the stand level are often underestimated. Emergent properties and statistical issues limit the effectiveness of reductionist approaches. A more holistic modelling of aggreg...

The cypress species Hesperocyparis lusitanica (Mill.) Bartel and H. macrocarpa (Hartw.) (formerly known as Cupressus C. macrocarpa) are widely grown in New Zealand where they noted for their high-value timber. Preliminary growth models were developed 2004 based on limited data. Here, we describe new stand-level these two using measurements from 521 permanent sample plots. Each model consists of...

While a large sum of timber stock in private forests, especially broadleaved forests, has been ignored by their owners, a rising global concern about climate change and ecosystems has led to a renewed interest in natural broadleaved forest management strategies. This study establishes the forest growth model for the natural broadleaved forest of Gangwon-do based on the matrix model developed by...

Proportional basal area (Pro-B) was developed as an accurate, easy-to-use method for making uneven-aged silviculture a practical management option. Following less than 3 h of training, forest staff from a range of professional backgrounds used Pro-B in an operational-scale field study to apply single-tree selection and group selection systems in longleaf pine (Pinus palustris Mill.) stands.
