forest yield tables

Stand density, in turn, is taken to be a function of site quality, age, and an initial measure of stand density. Source: National Exotic Forest Description (NEFD) yield tables. 3.2.1 Types of yield prediction models. national average yield class for privately owned commercial forests is between 12 and 14 (yield class 12 = 12 cubic metres of timber growth per hectare per annum, throughout the crop rotation). Forest carbon accounting models in use in Britain refer to the Forestry Commission’s yield tables (Edwards and Christie, 1981) for basic growth and yield predictions. The yield table is expressed in terms of total standing volume (TSV), total recoverable volume (TRV), and volumes of 3 generic log types, together with any production thinning volumes by age (1 to 40 years). Empirical Yield Table In contrast to normal yield tables, empirical yield tables are based on average rather than fully stocked stands. Inst. Species that were historically considered to be ‘commercial’ generally have their own set of yield tables. Managed stand yield tables describe the physical development of treated forests in quantitative units familiar to the planner, silviculturist, economist, protection specialist, and others responsible for implementing and assessing intensive forestry practices. Export citations. The oaks are most abundant in this type, usually occupying dominant and co-dominant positions within the stand. Development of Yield Tables SUMMARY P. M.

Achetez neuf ou d'occasion However, sustainability of timber products can be associated with uneven-aged forests as well. Presents in one volume a comprehensive edited collection of the available Italian volume tables and yield tables for conifers and hardwoods. Search. Forest management in this extensive region has been dependent on a number of volume and Yield studies (6,8,!J, 12, 18,29,30) based on local data, some of which were very meager. The National Exotic Forest Description (NEFD) region yield tables give the forest industry and MPI the underlying data used to produce wood availability forecasts. Noté /5. Because Because of the requirements of the models and limitations of the planning data, the main variable driving the yield models was age. 0161 495 4845 forestry@theapsgroup.com.

The new tables may be particularly useful for application to Sitka spruce stands managed according to prescriptions not covered in the original yield tables, and in providing improved predictions for unthinned stands. Book chapter Full text access. Forest Yield: A handbook on forest growth and yield tables for British forestry (PDF, 6.4MB) Yield models are one of the foundations of forest management. Yield class is an index used in Britain of the potential productivity of even-aged stands of trees. Individual yield tables are specified by a combination of tree species, yield class and management prescription. However, information on the site index for private and communal forests of Aomori as well as for national forests was not obtained. YIELD TABLES The oak-hickory forest type is the most prevalent of the upland hardwood types. The yield table is expressed in total recoverable volume (TRV), and volumes of 3 generic log types, together with any production thinning volumes by age (11 to 40 years for radiata pine, and 11 to 60 years for Douglas fir). However, sustainability of timber products can be associated with uneven-aged forests as well. Pages 504-506. Data Explorer This resource view is not available at the moment. Select REFERENCES.

A yield prediction model uses the quantitative relationships between measured growth variables to predict yields of forest types, and is a tool that helps to schedule and regulate harvests at sustainable levels.

By analogy with the Indian Forest Record Multiple Yield Tables for Deodar (Cedrus deodara, … They provide information about the patterns of tree growth and potential productivity that can be expected in forest stands of different tree species, with varying growth rates, when managed in different ways. There are numerous tables for high-forest stands of: (a) conifers-Abies alba, Picea abies, Larix decidua, Pinus cembra, P. halepensis, P. pinea, P. nigra and its varieties, P. pinaster, P. uncinata, Pseudotsuga menziesii, A. alba/P.

A normal-yield table is a tabulated statement of yields to be ex- pected from well-stocked, even-aged stands of a given timber type, at successive ages, for the range of site qualities characteristic of the type. Because it minimizes overfitting, it tends to be more accurate than a single decision tree. The yield tables in Forest Yield can be applied to around 150 tree species currently growing in the British Isles (see Appendix 1). Within this system, a range of management prescriptions is considered. Forest Yield has been developed for use in British forestry. Each has a special connotation for management.
