Abstract
The French National Forest Inventory was created in 1958 to assess metropolitan forest resources. To stick to new national and international requirements as well as to enhance reactivity, a new inventory method was implemented in 2004. This new method is based on a systematic sampling grid covering the whole territory every year. The size of the mesh is variable, locally adapted to the diversity and the fragmentation of French forests. The sample is defined for 5 years. It is divided into 5 annual systematic subsamples, each of which covers the whole country. The estimation method uses poststratification to enhance statistical accuracy.
