Estimation of aereal productivity in Pinus pinaster plantations in Central Spain
Abstract
Thinning of different intensity have been carried out on a 33 years old Pinus pinaster plantation and results have been compared with that of a witness treatment. The experimental design consists of randomized blocks. Standing biomass before thinning have been estimated through inventories and subsequent determination of modular values. Litterfall represented by leaf fall and dead branches has been measured as well as its evolution throughout the year on plots representing four different stand densities. The evolution of diameter growth has been studied as well for each stand density. Timber yield has been measured and compared with branch and leaf yields.
