Forest management
La parcelle visitée fait partie du réseau AFI (Association Futaie Irrégulière). Sa contenance est de 12 hectares. Le peuplement de hêtraie-chênaie irrégulière (jardinée) est fortement capitalisé en gros bois et très pauvre en bois moyens et petits bois.
From a text about forest management in Belgium. There is no problem understanding the sense of these terms. The difficulty is finding their correct equivalent - I am not having any luck finding any good forestry sites.

large/medium/small diameter wood
The first and the last of the trilogy get a good number of hits, but there is not a lot for "medium diameter".
I give below my "stream-of-googling" results.
Referred to as large/medium/small trees in:

But, diameter also comes into it:
The best watering method depends upon whether you have a small (1-7” diameter), medium (8-15” diameter) or large sized (16”+ diameter) tree.

Only two varieties here:
Sawlog (large diameter wood) is and will remain for the foreseeable future the most profitable product that a farm forest can produce. Sawlog can be produced quicker by carrying out thinning. Large volumes of pulpwood (smaller diameter wood) are produced in earlier thinnings. Local energy wood markets need this pulpwood and will make these thinnings more financially viable, particularly for smaller plantations.

Just fancied my chances finding something with "calibre", to no avail, but did come up with this:
Forest managers and scientists classify the size of trees by measuring tree diameter 4.5 feet (1.37 m) above the ground. This is the breast height of an average man, hence, the term diameter at breast height, or DBH. Based on diameter measurements, trees can be classified into the following size categories:
Tree Size Categories Based on DBH
Regeneration <3 inches <7.5 cm
Sapling/poles 1-9 inches 2.5-24 cm
Small trees 10-14 inches 25-37 cm
Medium trees 15-19 inches 38-49 cm
Large trees 20-29 inches 50-75 cm
Giant trees >29 inches >75 cm
http://cse.pdx.edu/forest/forest_class_size.htm
This does not sit well with the above, however:
petit bois (PB, moins de 30 cm), bois moyen (BM,. entre 30 et 60 cm), gros bois (GB, de 60 à 90 cm) et très gros ...

: Use the word "timber" rather than wood. I recommend JWA Newhouse 1974 A Handbook of Forestry and Woodland Terms (ENG-FR-ENG)

I tried searching with "timber", but just plain "wood" appears to be what the spcialists say (some of them, anyway). "Timber" does sound more technical though (but only to untechnical ears, maybe). Hug a kauri tree for me please!

these are not tree size classes
Go to this web page where you'll find how a tree is stratified in three sections by foresters assessing its timber potentials:
http://www.boisenergie.ifn.fr/lexique.php
The lower section of the stem is called "bille de pied" in French and for timber exploitation purposes is the butt log containing the "bois fort commercial", i.e. the tree section containing the highest timber volume.
The upper section of the tree stem (up to the collar) is "petit bois", and the reason why it is called so is self-explanatory.
The crown contains the "menu bois" yielding smaller diameter logs.
In this particular stand ("a futaie jardinée"), silvicultural work and thinning operations were conducted in a way that would promote timber yields in "gros bois" (i.e. larger diametre classes from lower stem sections) in all or most of all tree age classes, and only small quantities of "petit bois" from upper tree strata.
