Wood density

Ok I forgot to post yesterday, so I'm doing it now. Wood density is another one of the complicated parameters I'm going to deal with. I'm quite certain that I can't do any increment boring here, so I'll either get the data from our neighbours, or use models to estimate wood density. Well I read somewhere that genus level values for a species' wood density works pretty well. So I guess that's my next step! Also I need to know how other papers got their density values for each species, so I can take an average from the references.
