THE “BERGERIE DE BERDINE” SELLS HEATING WOOD

For many years, the association “Bergerie de Berdine” has been selling heating wood to individuals, in the Vaucluse (84), Alpes de Haute Provence (04) and Bouches du Rhône (13) departments. This wood, coming from plots bought and operated by the association, is exclusively made up of oak and beech. It can be sold on site (hameau de Basses Courennes in St Martin de Castillon 84750) or delivered at home. The sale is based on cubic meter, not stere, in 0,50m or 0,33m or 0,25m logs, wood delivered and piled up at the client’s place.

COMPARING VISIBLE VOLUMES

The volume of heating wood is generally expressed in “steres”, 1 stere being the visible volume of a stack of 1m long over 1m wide and 1m high. The real volume (expressed in m3) would be that of the logs without the voids. On average, it is considered that 1 stere amounts to 0,70 m3. The relation between these two volumes is called the piling coefficient (or factor). It depends mainly on the shape and the length of the final logs (50 cm or 33 cm) obtained from the initial 1m ones, but also on the variety considered (smooth or rugged bark) and the logs diameter.

This means that from one stere of 1m long logs, one gets on average :

  • * 0,80 stere of logs recut in 50cm
  • * 0,75 stere of logs recut in 33 cm,
  • * 0,60 stere of logs recut in 25 cm,

as is displayed on the diagram hereunder (source “Centre Technique du bois” – Wood Technical Center)

Représentation du facteur d'empilage
cut in 0,33 cm – cut in 0,50 cm – cut in 1,00 m
Due to this piling factor : 1 m3 of logs cut in 50 cm represents 1,25 steres.

HEATING WOOD IN VAUCLUSE

Many forests are treated as thickets in the department.

Most leafy hardwoods (oaks and beeches) have the ability to grow suckers from the stump of cut trees. The thicket is mostly made up of sprigs coming from the development of suckers, as opposed to the timber where trees come from seeding.

When the population is considered mature (25 to 30 years), the plot undergoes a clearcutting, so that the suckers may all have the same age. The ability to grow suckers with strength maintains for about 40 years on average. In Vaucluse, management in thickets has been used for long, to rejuvenate regularly the forest and supply heating wood. This type of management consists in cutting close to the ground, about every 30 years, the sprigs coming out of each stump. With such sylvicultural treatment, the new sprigs are straight, of low diameter and are perfect for use in due time as heating wood.

The main varieties used as heating wood

  Advantages Inconveniences
Live oak Very dense wood
Long lasting in fire
Important calorific capacity
White oak Straighter wood Less dense
Lower duration and calorific capacity
Beech Smoother bark, less messy
Ideal for boilers and stoves
Cannot be stored several years
