Growth modeling of Albizia niopoides (Mimosaceae) using dendrochronological methods. The annual growth rings in tropical trees are fairly common, but their study is relatively recent. Growth rings were found in trees of Albizia niopoides from the Porce River Canyon, Central Cordillera of the Colombian Andes. A total of 33 cross-sections were collected from trees distributed throughout the study area from 664-870masl. Cross-dating, spaguetti plot and 14 C analyses were used to demonstrate ring annuality, assuming as hypothesis that
