Descrição detalhada da prática ou projeto

The methodologies evaluated have been adjusted to the usual way of working in the area, without considering alternatives for the use of the machinery, contrasting the yields associated with the modality of taking out cups or of complete tree as biomass (chips) and conditions. The success of obtaining forest products, whether wood or biomass, is subject to accessibility to the stands under treatment, to the distances of take-off and unloading to which the products must be subjected and the possibilities of access to heavy machinery or transport elements of adequate dimensions. This is why there have been a series of activities complementary to the performance prior to the work, such as the scarification of the track and the pruning of feet to facilitate the access of the vehicles, the reconstruction of slopes and the correction of hours and roads of take out.

Plot 1_Baldíos: Plot with an area of 4.2 ha. The slope is between 50% and 100%. The stonyness is 30% and during the execution of the works it has been found that around 35% of the area presented abundant mud. The maximum distance to the track is 200 meters. The loading dock is at a maximum distance of 150 meters from the track. The presence of holm oaks is significant; however, the operations of attachment and cutting can be carried out without being affected. The species that has been harvested has been the pinion pine (Pinus pinea) with pyramidal crown morphology. According to the Management Project, plot 1 has the following dasometric values (shared with plot 2): 1,582 feet / ha, with 737 feet / ha with a diameter of less than 12 cm, 786 feet with a diameter between 12.5 and 22.5 cm, and 59 feet between 22.5 and 32.5 cm.

Plot 2_Baldíos: Area of 4.0 ha. The slope is between 50% and 100%. The stonyness is 30% and during the execution of the works it has been found that around 40% of the area presented abundant mud. The maximum distance to the track is 175 meters. The loading dock is at a maximum distance of 50 meters from the track. As in plot 1, the presence of holm oaks is significant; however, the operations of attachment and cutting are perfectly compatible.

Plot 3_Baldíos: Area of 3.7 ha. The slope is between 50% and 130%. The stonyness is 30% and during the execution of the works it has been found that around 40% of the area presented abundant mud. The maximum distance to the track is 80 meters. The loading dock is at a maximum distance of 1,000 meters from the track. The presence of holm oaks is significant; however, the operations of attachment and cutting can be carried out without being affected.

El desarrollo de los trabajos en la zona de estudio ha estado condicionado fundamentalmente por el efecto de la pendiente y la presencia de agua y barro en el terreno, determinando y condicionando la adherencia de los medios que intervienen en la extracción (desembosque) a las zonas de acopio de los pinos cortados. En estas zonas de acopio, ubicadas a lo largo de una faja cortafuegos , el espacio disponible y su accesibilidad es suficiente para el desarrollo de las operaciones de astillado, carga y transporte del producto generado

The development of the works in the study area have been fundamentally conditioned by the effect of the slope and the presence of water and mud on the ground, determining and conditioning the adhesion of the means involved in the extraction (disembarkation) to the areas of gathering the cut pines. In these collection areas, located along a firewall, the available space and its accessibility is sufficient for the development of the chipping, loading and transport operations of the generated product.
