Simulated Yields for Managed Northern Hardwood Stands
Author: Dale S. SolomonPublisher:
ISBN:
Category : Forests and forestry
Languages : en
Pages : 28
Book Description
Board-foot and cubic-foot yields developed with the forest growth model SlMTlM are presented for northern hardwood stands grown with and without management. SlMTlM has been modified to include more accurate growth rates by species, a new stocking chart, and yields that reflect species values and quality classes. Treatments range from no thinning to intensive quality product management over a range of sites.

Book Description
S2SIMSAP and SlMTlM are computer programs that have been developed to simulate the stand growth and development of natural and treated even-aged northern hardwood stands. SIMSAP begins with species distributions by quality classes in sapling stands after regeneration. SIMTIM, the poletimber-sawtimber-harvest phase, uses stocking guides based on quadratic mean stand diameter, number of trees, and basal area per acre of trees in the main crown canopy. Using available data, the connecting phases of the models have been tebted to determine the effects of silvicultural treatments (or no treatment) on long-term stand response. The models are coded in FORTRAN 77 and are available on mainframe and IBM compatible microcomputers with a minimum of 256 K.S3.

System 6 Alternatives

Book Description
S2Three system 6 mill-size alternatives were designed and evaluated to determine their overall economic potential for producing standard-size hardwood blanks. The study focused on developing standard discounted cash flow measures. Internal rates of return ranged from about 15 to 35 percent after taxes. Secondary effort was directed at providing accounting cost summaries to facilitate cost comparison of standard-size blanks with rough-dimension stock. Cost per square foot of blanks ranged from about $0.88 to $1.19, depending on mill size and the amount of new investment required.S3.
