Pâturage ovin sous forêt de Pin sylvestre. I. De l'intérêt des activités sylvo-pastorales

In the dry calcareous Préalps area, in the South-East of France, on a natural extension area of Pinus sylvestris L., an experimentation of sylvo-pastoral management has started on plots (average size: from 1 to 2 hectares), where there were up to 3,000 to 4,000 plants of Scots pine per hectare, at the beginning. There are three densities of stands (120, 240 and 400 plants/ha), combined with three agronomical treatments (the first one: the natural fodder species are conservated; the second one: the same plus fertilization; the third one: the second plus seeding of cultivated fodder). Each of these is grazed by a sheep-flock of 350 animals. On the most intensified plots, forage production has been multiplied by five and the pastoral value factor by three, in five years. Pasture days for the same sheep-flock has moved from 2,400 pasture-days in 1987, to about 15,000 pasture-days, in average, since 1991. Another important result of this experimentation is that the free brushed pastures are less and less grazed by sheep, for the benefit of some other brushed pastures which have been enclosed and improved for a short period of time.
