Dear foresters,

I did before request information about the main wood harvesting systems 
in European countries and the biomass distribution of pulpwood tree 
species.

Now I have calculated weight precentage of foliage, branches, stemwood 
and stemwood bark by the M.G.R Cannell's work: World forest biomass 
primary production data. Here is my results. 

             age      foliage    branches    stemwood    bark
Beech        59        2         27          66           5
(German)     80        2         16          77           5
(Danish)     85-90     1         20          76           3
Pine 
Maritime (UK) 18       12        25          44           19
              28       7         16          58           19
              48       5         10          66           19
Sylvestris    18       11        24          52           13
              28       5         15          71           9
              64       4         14          70           12
(Spain)       80       6         18          68           8
Spruce        87       7         12          75           6
(Picea, German)
Poplar
(Japan)       25-40    2         19          79
Eukalyptus    9,5      13        9           63           15
(Globulus, Australia)

I am going to use these numbers for calculating average tree biomass 
distribution for used pulpwood in following countries: Denmark, Germany, 
France, United Kingdom, Austria, Italy, Portugal and Spain. If anybody 
has anything to comment about these numbers I would be very pleased to 
hear.  

    Waiting for comments,

                     Samuli Toivanen

P.S I'm still short with those main pulpwood harvesting systems in 
following countries: Austria, Italy and Spain. I would also like to get  
more cost information of pulpwood harvesting from every earlier 
mentioned country.
