Contour felled log barrier (María Burguet (University of Valencia. Dept. of Geography. Blasco Ibañez, 28, 46010))
A foreseen wildfire is expected for the summer 2015 in the Caroig mountain range. Area was afforested by Aleppo pines during last XX century and nowadays landscape is composed by mature Aleppo pines at different stages of development and, the understory shrub vegetation.
The research team of the University of Valencia will implement an experiment based on the contour-felled log erosion barriers technique to capture and measure post-fire soil losses in a natural burned landscape
Purpose of the Technology: Contour-felled log erosion barriers are designed to increase detention and infiltration of overland flow, thereby reducing runoff and sediment transport capacity
Establishment / maintenance activities and inputs: The standard installation technique consists of felling burned trees and laying them on the ground along the slope contour. Each log is anchored in place and gaps between the log and the soil surface are filled with soil to create a storage basin on the upslope side of the log where overland flow is trapped
Natural / human environment: The Aleppo pine trees in the region are typically planted as monoculture for wood production. The landscape reflects a long history of intense land management, with a mosaic of (semi-)natural and man-made agricultural (terraces) and afforested lands. Since the 1970´s, however, wildfires have increased dramatically in frequency and extent, driven primarily by socio-economic changes.
