Short History of the site

OWNER: City council of Moral de Hornuez. POTENTIAL VEGETATION: Serie 22a Supramediterranean castellanomaestrazgo-manchega basophilic of Quercus rotundifolia (Junipero thuriferae-querceto rotundifoliae sigmetum). (Source: Rivas Martinez, 1987). DESCRIPTION OF THE ENVIRONMENT: The environment is characterized by its morphology observed more or less smooth transition between the Sierra de Pradales, (small saw culminating at 1377 m. on the hill called “Peñacuerno”), and Riaza river valleys. Currently there are no trees because of the fire happened in August 2008, which burned about 900 ha. Now the vegetation is limited to herbaceous colonizing like the yellow lupine (Lupinus hispanicus) and asphodel (Asphodelus Albus). In 2010 began the restoration and reforest works the burned area. PREVIOUS MANAGEMENT AREA: Stand of Pinus pinaster orderly using the method of moving sections. The turn will be articulated in 80 years with implementation period of 20 years. The stand on which is located plot was in the Regeneration Group.CURRENT STATUS OF THE LAND BEFORE PLANTING THE ARBORETUM: Clean burned area. Until 2008 was populated with Pinus pinaster from natural regeneration. In August 2008 suffered a fire and today is satin and with short stumps formed by post-fire cut. SUSCEPTIBILITY TO PESTS AND DISEASES: Not detected the existence of particularly virulent pest attacks and other diseases. There have been sporadic episodes of processionary (Thaumetopoea pityocampa).
