The forest is a determinant component of the landscape on the nine islands of Azores archipelago. Covering about 1/3 of the territory, the Azorean forest supports a sector responsible for 1.400 jobs, generating an annual income of about 1.8 million euros by direct sale of timber, and 10.9 million euros on the first wood process industries.

The Azorean forest area has 12.698 hectares of Japanese cedar (Cryptomeria japonica D. Don) pure and mixed plantations. About 4.500 hectares of those are under Regional Government management, with 2.119 hectares in São Miguel Island.

Taking into account its importance, the forestry strategy defined for the Azores Autonomous Region is based on the promotion, incentive and modernization of the forest based sector, and also through responsible forest management.

Through the implementation of a management system in accordance with the standards of the major global certification initiatives, the Azorean Government intend to establish long term production and conservation commitments with important effects on land use planning. This process began with the certification of a pilot area in January 2014, and the Government intends to extend the certification to all public forest areas.

FOREST INVENTORY

The Government of the Azores through the Regional Directorate for Forest Resources develops the Forest Inventory, which main objective is to generate graphical and numerical information on land use, as well as the assessment of wood material. All of the generated information is incorporated into a GIS, with all of the advantages associated in synthesis, analysis and intersection of various types of information.

MANAGEMENT AND FOREST CERTIFICATION

The program of Azorean Goverment announce the development of the area as one of the strategic options, proposing the creation of a stable foundation for sustainable development. 

The forest is a determinant component of the landscape on the nine islands of Azores archipelago. Covering about 1/3 of the territory, as well as the economic importance of local forest sector and its potential for expansion, the forestry strategy defined for the Azores based on the promotion, incentive and modernization of the forest, and also through responsible forest management. 

Through the implementation of a management system in accordance with the standards of the major global certification initiatives, the Azorean Government intend to establish long term production and conservation commitments with import effects on land use planning.


The forest management certification is a credible message that can be passed on to the market and consumers, garnering sympathy and preference of choice, creating opportunities to access markets that making better use of forest products, especially wood. 

Also important to consider the value of so-called "forest service" as the protective functions, conservative and stabilizing soils, waters, pastures and biodiversity, the resulting landscape composition and recreational and educational uses.  These services have a direct influence on the quality of life, tourism and its economic results, and may have even greater value is associated with a certified forest management.

INTERNATIONAL PUBLIC COMPETITION

The unique characteristics of cryptomeria, the controlled origin of the wood and the forest management certification are decisive factors for integration of Azorean forest products in the international market.

The Azorean Government with an active management of public forests, has started a process of international public competitions intended to sale standing wood, mainly Cryptomeria japonica stands, including the reforestation of the cut areas.

The total area of public Cryptomeria stands on São Miguel Island is 2119 hectares. The forest management plan forecast the harvest of around 100 hectares per year, representing about 80.000 cubic meters to be placed in the market.

WOOD TRANSFORMATION

Conversion
Easy sawing. Satisfactory fuzzy surfaces.
Easy pelling and plan cutting, due to low transversal cohesion.

Drying

Workability
Very delicate due to low hardness.
Fuzzy surface and susceptible to dents.
Difficult molding.

Jointing and Fixing
Good for gluing with steady gaskets.
Good reception of metal elements but with low fixation.

Finishing
Very delicate due to wood mildness.
Good reception of finishing products: woodstains, paints and varnishes.
