The development of the forestry component allowed to specialize, thereby enabling the possibility of creating services as a business segment. Services emerge as a natural consequence of the expertise acquired internally, that the Yser decided to make available to the market.

The services offered are geared to holdings of forests (coniferous) from pine. Studies to the implementation and regeneration of forests, as well as exploration and operational management of coniferous forests are the main areas of activity.

Yser meets a set of principles to ensure economic sustainability, environmental and social activities. On the other hand, considers it essential to use innovative technologies and processes. In this context there is a constant challenge in finding solutions which make forestry operations more efficient, particularly in the extraction process of resin.
