The area occupied by eucalypts in Galicia (NW Spain) is currently more than 400,000 ha, with the most widespread species being blue gum (Eucalyptus globulus Labill). Every year about 4 million cubic metres of E. globulus are felled in Galicia, representing almost 40% of the harvest volume of all species in Spain and approximately 75% of the harvest volume of the species in the country

This website provides a tool for estimating growth and production in volume, biomass and carbon content of first rotation E. globulus plantations in Galicia (NW Spain)


Project AGL2010-22308-C02-01 “Modelling the growth and production of clonal and seedling plantations of Eucalyptus globulus Labill. in NW Spain”, funded by the Spanish “Ministerio de Ciencia e Innovación” and the European Union through the European Regional Development Fund (ERDF program) for 2011-2013. Funded by the company ENCE in 2014

The EucaTool® application

EucaTool® is only applicable to regular first rotation Eucalyptus globulus stands in NW Spain, of age between 3 and 21 years, with dominant tree heights up to 40 m and diameters of up to 70 cm

Access to the application

Download the User’s Manual (Spanish only) 

The authors and the Sustainable Forest Management Unit (UXFS) are not responsible for wrong use or interpretation of the results obtained by the application

Where can it be applied?

Regular, clonal and non-clonal first rotation Eucalyptus globulus stands in Galicia (NW Spain), aged between 3 and 21 years, with dominant tree heights up to 40 m and diameters up to 70 cm. EucaTool® is not applicable to Eucalyptus nitens plantations in the region

Why was it developed? 

To provide forest stakeholders (owners, companies, administration, scientists, teachers, students, etc.) with a free, easy-to-use application designed to estimate production and evaluate different management options for eucalyptus plantations in Galicia (NW Spain)

How was it developed?

A network of 128 plots covering the entire area of distribution of ​​the species in Galicia was established and measured three times (at one-year intervals), and 87 sample trees were also cut, chopped and measured. The data obtained were fitted to several equations, which together form a dynamic model of growth and production for the Eucalyptus globulus plantations in Galicia. The model is implemented in the application

What is it used for?

EucaTool® allows estimation of 

- Volume (with and without bark), biomass and carbon, current and future

- Growth in volume, biomass and carbon

- Changes in dominant height, basal area and density (number of trees per ha)

- Plantation productivity (site index)

- Rotation age (maximum volume income rotation age)
