A wildfire is expected for the summer 2015 in the Caroig mountain range. The area was afforested with Aleppo pines during the 20th century and nowadays the landscape is composed by mature Aleppo pines at different stages of development and shrub vegetation in the understorey.
The research team of the University of Valencia will implement an experiment based on the sediment fences technique to capture and measure post-fire soil losses in a natural burned landscape.
Purpose of the Technology: The post-fire environment will be developed in a natural process. Burned logs, trees and ashes will promote soil cover and together with the lack of intervention with heavy machinery, is expected to decrease soil erosion by increasing roughness, decrease of runoff velocity, and increase water infiltration.
Establishment / maintenance activities and inputs: There are no maintenance activities since the main purpose is the natural re-vegetation.
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.
