II. Context of the study and the problem

Landes of Gascony : about 1 000 000 ha.

Extends over 3 departments: Gironde, Landes and Lot-et-Garonne.

The most of them are artificial regeneration.

Species: Maritime Pine (Pinus pinaster) and of the Oak (Quercus sp).

This forest massif is regularly the object of disasters (fires, storms, insects, etc.) which attenuates the production of wood.

II. Development of process for estimate the damages on the plots

● Dendrometric datas (Measuring diameter and heigth of twelve tree per stand because it is a contemporary mass ).

● Evaluation of damage’s percentage- <20% - Between 20 and 40% - Between 40 and 60% -> 60%.

● Evaluation of the age of the stand (counting whorls).

● Percentage of natural regeneration (As the evaluation of damage´s percentage).

1/ Caller identification (Name, address, type of owner, bank account)

2/ Project features (Name of the town, surface cleaning, surface reforest)

3/ Forward spending calculated according to the previous (Amount and nature of the scale ex: N20, N21, N22)

3 Steps:

V. Establishment of suggestions of cleaning and reforestation

For cleaning and reforestation we considered several criteria:

● The total area of the plot ● The area affected in the plot ● The cost of the work required ● The average diameter and stand age

● The presence of various species

● Presence of regeneration or not

VI. Conclusion

● We have seen in the Local Initiative Module (LIM) to diagnose the status of plots damaged.

● We have based on studies of CRPF Aquitaine and the National Forest Inventory.

● Mr. COQUILLAS, forestry technician from the CRPF, established the plots affected by the storm.

● So we could make a file for grant subvnetion.

● When the file of subvention will be accept, the owner will receive help for cleaning plots and for the reconstitution of forest cover.
