The nursery at Gerri was created in the year 1906 to cultivate trees for reforestation of the Enseu gorge, in order to correct its water and forestry features. The lack of plant coverage in the catchment area and therefore the negligible capacity for intercepting and retaining rainfall was one of the causes of the sudden and serious flood of 1903.
The reforestation of the basin ended in 1950, but the nursery continued supplying trees for diverse repopulations in the district until the end of the 1990s.
Today, it has been adapted as an ''Information Point on the Natural Areas in the Pre-Pyrenean Mountain Ranges of the Pallars'' which shows the main fauna, botanical and botanical-cultural elements of this region.
In different borders, combinations of the main plant species representative of the natural communities of this area of the Pyrenees have been planted.
The lower terraces have been devoted to growing different varieties of horticultural plants that people in the country historically grow in their fields, in addition to plants of culinary or medicinal interest.
Posters on one side of the nursery inform visitors of the typical animal and plant components of the different seasons in the Pyrenean mountains.
On the other side of the gully, on a level with the nursery, more posters provide information on the diversity of large birds that live around the Pyrenean area being visited.
