2.1 Short description of the Technology

Definition of the Technology:

Reforestation refers to establishment of forest on land that had recent tree cover.

2.2 Detailed description of the Technology

Description:

A wildfire is expected for 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 with shrub vegetation in the understorey.

Purpose of the Technology: The post-fire area is expected to be reforested with local shrubs species and Aleppo pines.
Perturbation by machinery when reforesting is expected to increase soil erosion.
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 reforested burned landscape.

Establishment / maintenance activities and inputs: Maintenance activity deals with the plantation scheme which includes man-power, machinery, access to remote areas and cost of plants, as main expenses.

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.

2.3 Photos of the Technology

2.5 Country/ region/ locations where the Technology has been applied and which are covered by this assessment

3.2 Current land use type(s) where the Technology is applied

Comments:

Major land use problems (compiler’s opinion): It is expected that after a wildfire runoff and soil erosion will increase, resulting in a decrease of on-site fertility and derived off-site effects such as loss of water quality, soil water storage, higher risk of flooding and damage to human life.

Major land use problems (land users’ perception): Loss of wood resources.

Plantation forestry: Aleppo pine plantations

Forest products and services: timber, fuelwood, fruits and nuts, grazing / browsing, other forest products / uses (honey, medical, etc.), nature conservation / protection, recreation / tourism, protection against natural hazards

6.7 Strengths/ advantages/ opportunities of the Technology

Strengths/ advantages/ opportunities in the land user’s view
Local species and new tree plantations are seen as future local production. How can they be sustained / enhanced? Selecting local species.

Strengths/ advantages/ opportunities in the compiler’s or other key resource person’s view
Reforestation with local species must to be done based on a previous assessment of the fire effects on environment. Removing burned logs and planting trees and shrubs with heavy machinery could lead the system to a degradation stage instead of decrease soil losses. How can they be sustained / enhanced? It could be enhanced by the evaluation and preselection of areas suitable to be reforested.

6.8 Weaknesses/ disadvantages/ risks of the Technology and ways of overcoming them

Weaknesses/ disadvantages/ risks in the compiler’s or other key resource person’s view	How can they be overcome?
Impacts of heavy machinery in a fragil post-fire environment.
