CROWN MORPHOMETRY FOR TWO VALUABLE TIMBER SPECIES FROM MIOMBO WOODLAND IN MOZAMBIQUE

Pterocarpus angolensis DC and Bobgunnia madagascariensis (Desv.) J. H. Kirkbr. & Wiersema are two hardwood species found in Miombo woodland. Crown size, being closely related to the photosynthetic capacity of a tree, is an important parameter studies growth individual trees. In this sense, present study aimed morphometric relationships P. B. as resource describe features these species. Data were sampled 60 rectangular plots 20 x 50 m, systematically distributed within forest. each plot, diameter at breast height (DBH), (h), crown insertion point (cih) four radii all trees with DBH ≥ 10 cm measured. Results indicated that length grow increase, larger crown, greater dimensions; for madagascariensis, have shown low correlation when considering DBH. It was concluded influence on tree measures description planning silvicultural activities be performed natural forests. The results interest forest managers since they make decisions about operations. Keywords: prediction models; umbila; pau-ferro; management.
