Abstract

A reforestation was realized on the subalpine belt (1800 m asl) by using a direct seed system and biodegradabile plastic protections. This method, developped in Sweden and used with success in the Swiss central Alps, is tested in the western Alps in high summer drought conditions. the reforestation was realized by using a scheme of small groups formed of microcollectives of 15 plastic protections. In every protection have been put 4-6 sedds of Norway spruce. The controls have begun at the end of the first vegetative season.
