>>Dear J.E., > >I would suggest you to document yourself on stand density management >diagrams (SDMD), a tool developed by Drew and Flewelling (1979, >For.Sci.518-532). These diagrams are based on the -3/2 self-thinning law, >which states that there is a linear relationship between the maximum >density that can be reached by a stand and the mean tree volume, when both >variables are plotted on a logarithmic axis. SDMDs also relate mean stem >volume and stand density to dominant height and mean quadratic diameter. >By coupling a SDMS with site index curves, it is possible to simulate the >evolution of a stand in time, and therefore "see" the impact of spacing or >competition on the stands characteristics. If you are interested in SDMD, >I also suggest you the reading of Peter Newton's article on black spruce >DMD (For.Chron.69:412-430); he also has a WWW site >(http:www.nefc.cfs.nrcan.gc.ca/pnewton/stand_density/sdmd1.html) that is >quite nice... > >I you need more info, please write me back: I'll be pleased to help you! > >Best regards, > > Jean-Martin Lussier, ing.f., Ph.D. Unité de recherche et de développement forestiers de l'Abitibi-Témiscamingue Université du Québec en Abitibi-Témiscamingue 445 boul. de l'Université, Rouyn-Noranda, Québec, Canada J9X 5E4 Tél: (819) 762-0971 poste 2536 Fax: (819) 797-4727
