This file was created by scanning the printed publication. Mis-scans identified by the software have been corrected; however, some errors may remain. Yield tables generated by the stand simulation program DFSIM (Douglas-Fir SIMulator) are presented for. a number of possible management regimes. These include a "normal" yield table; tables for stands planted or precommercially thinned to 300 and 400 trees per acre; tables for commercially thinned stands with and without prior commercial thinning; and tables illustrating the effect of fertilization with nitrogen. Guides are presented for number of trees to be planted or left after precommercial thinning and expected time of first commercial thinning.
AuthorsThese tables can be used as aids in choice of management regimes, guides to stocking control, and as a partial basis for estimating probable yields of future managed stands. Their limitations arise mainly from limitations of the basic data used in construction of DFSIM. Users are cautioned on some misinterpretations.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
