Dear Nathan,

maybe this thesis is of help:

http://tesi.cab.unipd.it/42711/1/Cosola_Giulio.pdf

and this paper:

http://hrast.sumfak.hr/~nms/v35/nestorovski.pdf

https://www.researchgate.net/publication/286871127_Analysis_of_Energy_Value_of_Some_Tree_Species

This paper presents the investigation of five (5) characteristic forestry species (Fagus ×moesiaca (K. Malý) Czeczott, Quercus petreaea (Matt.) Liebl., Quercus pubescens Willd., Carpinus orientalis Mill., Pinus nigra J. F. Arnold) that cover the major part of the total forest area, and account for around 70% of the total forest reserve in the Republic of Macedonia. .... The purpose of this investigation is to establish the energy value of these species at different trunk height and different parts of the tree (wood, bark) in order to determine the differences due to different cell structure.

I wonder if the quality as fuel was the main criterion, but if availability or processibility might have also have played a role.

Best wishes,

Stefan

Hi Nathan

About calorific value of Pinus silvestris L. see:

Hi Maciej

Thanks very much for this, it is very much appreciated.

Thomas May

I don't have any references about calorific values of Anatolian pines. But I have some experience with firwood use in the Dominican Republic and Haiti, where another native pine species is present (Pinus occidentalis). In the Dominican Republic, people do not like pine at all as firewood for the smoke it produces, for the high resin content. They prefer any other species, even at places where pine is by far the most dominant tree. In the neighbouring Haiti, I know a pine forest area where people use pine as firewood, there is hardly any other tree species available.

Use of pine as firewood under present conditions in Dominican Republic and Haiti would indicate that other sources of wood are very scarce, so people are forced to use pine, in spite of the smoke that it generates.

Hope this comment could have been useful.

Best regards!

Thomas
