Volume equations for natural Taurus cedar stands in West Mediterranean Region
Taurus cedar (Cedrus libani A. Rich.) is one of the most important tree species in Turkey. Therefore, the information is necessary about growth and yield of the species for developing future management and planning strategies. The one of the essential building blocks in forest growth and yield predi...

Taurus cedar (Cedrus libani A. Rich.) is one of the most important tree species
in Turkey. Therefore, the information is necessary about growth and yield of
the species for developing future management and planning strategies. The one of the essential building blocks in forest
growth and yield prediction models is the equations for estimating individual
tree volume. In this
study, tree volume equations were developed for Taurus cedar stands in West
Mediterranean Region. The tested models were compared using six performance
criteria (Fit index, average bias, average absolute residuals, absolute maximum
bias, and Akaike Information criteria) for model development and validation
dataset. According to relative ranks of models, the best volume equations are
Takata (1958) and Schumacher-Hall (1933) for Taurus cedar. As a result, tree
volume can be estimated with high precision using Schumacher-Hall (1933)’s
equation for natural cedar stands in this region. |
