According to data from the last National Forest Inventory (IFN6), the Portuguese forest is made up of four major groups:

• Cork oak and holm oak forests, representing 34%;
• Pine forests, representing 30%;
• Eucalyptus forests, representing 26%;
• Deciduous hardwoods, composed mainly of oak and chestnut trees, representing about 10% of the total forest area.

The main characteristic of the Portuguese forest lies in its large diversity. In Portugal, no species occupies more than one third of the total forest area.

At Humus, we actively contribute to preserving such diversity, recognizing the importance of ecosystems' biological diversity, which we protect through the adoption of sustainable forest management practices.

The responsible way we manage our forest areas has been repeatedly recognized by the PEFC (Programme for the Endorsement of Forest Certification Schemes), and by the FSC^® (Forest Stewardship Council^®). These entities certify that we use the best forest management practices, and comply with the strictest international criteria.

Because we share with the Forestry Association of Baixo Vouga the goal of ensuring the sustainable use of our region's forestry resources, we have since long established a close relationship with this Association, which has been vital for the development of our forestry activities.
