From monitoring in the field to specialist studies

Gaëtan du Bus de Warnaffe, a freelance forestry engineer based in Occitanie, shares his extensive forestry expertise with many independent forest owners, mainly in the départements of Tarn, Aude and Ariège. He also visits other parts of France on on-off assignments.

Gaëtan worked as a planning specialist in the public forests of Ardenne, before embarking on a PhD in science, which led him to applied research with the INRA. He then became a forestry management trainer.

He now works as a forestry consultant and his experience combining research, vocational training and practice in the field let him take a holistic approach to the sometimes complex scientific and economic questions related to forestry management.

He is an accredited professional forest manager and a probationary member of Experts Forestiers de France (French forestry consultants’ union).

From monitoring in the field to specialist studies, a broad array of skills

Gaëtan worked as a planning specialist in the public forests of Ardenne, before becoming a researcher in applied ecology in a university and with the INRA, then a trainer for the Advanced Technical Diploma in Forestry Management. He is now a forestry consultant with experience that combines research, vocational training and practice in the field, letting him take a holistic approach to the complex scientific and economic issues involved in forestry management.
Forest owners make a long-term investment and play a fundamental role in matters of rural development, climate, soil fertility and biodiversity. Investing capital and generating timber and income is possible with a fine, diversified forest that contributes to the local economy.
Reflecting the philosophy of the Pro Silva association, ABC applies a forestry management approach based on a mixed, uneven-aged stand wherever possible (continuous, diversified forest cover), a dynamic system that minimizes costs while conserving and improving the asset. This approach only allows clear felling when stands are in poor health or unsuited to the soil or local climate. Deciduous and mixed stands are respected, natural regeneration preferred and plantations are mixed.

A winning partnership

We meet forest owners and forge a relationship based on transparency and trust, taking into consideration each party’s objectives. The diversity of the forests and of their owners always leads to new discoveries and stimulates creativity. Arbre et Bois Conseil helps forest owners to get to know, value and take care of their forest, for now and for the future.
