Seed-Tree and Shelterwood Regeneration Methods. As management treatments have developed, there have also been advances in the development of quantitative tools for uneven-aged forestry. Measuring site quality is more difficult in complex stands where free-to-grow trees are not present for use in traditional site index measurement (Berrill and O'Hara, , Fu et al., ).

the decisions in uneven-aged management. In order for regeneration to occur on an on-going basis, the stand must be maintained at a relatively low density and openings must be created frequently. Thus, uneven-aged management is characterized by frequent harvests—usually every 5 to 15 years. Two perennial problems in the management of uneven-aged forests are considered: (i) determination of the optimal sustainable distribution of trees by diameter class, i.e. stand structure, for a given initial stocking level, and (ii) the optimal cutting schedule for the conversion of an irregular stand to a target is shown, using examples for northern hardwood stands in Wisconsin Cited by:   An illustration of the two forest management systems to be compared in this study: the even-aged (a) and uneven-aged (b) forest management. At stand level, even-aged management comprises a clear and repetitive cycle of distinct phases, including the regeneration, growing, and thinning, and final harvesting where typically a low number of live retention trees are leaf on the clear Cited by: Expanded coverage includes a case study of a closed canopy, uneven-aged forest, new forest plans from South America and Oceania, and a new chapter on scenario planning and climate change adaptation. Key Features.

There is a strong movement towards uneven-aged forest management based on the idea that such stands increase or at least maintain soil fertility, increase biodiversity, and improve stand resilience. This shift in forest management practice renders existing yield tables increasingly unreliable. Hardwood Silviculture: Even-aged and Uneven-aged Systems. Hardwood silviculture is extremely complex. More than 40 commercial hardwood species make up the southern hardwood forest. These commercial species grow in association with one another and are mixed with an additional species. Forest Management and Planning, Second Edition, addresses contemporary forest management planning issues, providing a concise, focused resource for those in forest management. The book is intermixed with chapters that concentrate on quantitative subjects, such as economics and linear programming, and qualitative chapters that provide Cited by: The papers presented at the meeting included several on uneven-aged silviculture and can be found in Forest Ecology and Management (volume ()).
