Os índices morfométricos podem ser usados para subsidiar o entendimento da dinâmica de florestas naturais. Diante disso, objetivou-se descrever e avaliar as características morfométricas e dendrométricas de Araucaria angustifolia, como subsídio para compreensão da estrutura da floresta natural de araucária. Os dados foram mensurados em três municípios de Santa Catarina, considerando diferentes altitudes de ocorrência da espécie, com amostragem de 247 árvores, utilizando o método de Bitterlich, sendo medida a circunferência a 1,30 m do solo, altura total e de inserção de copa e raios de copa. As relações interdimensionais das árvores foram descritas por meio de índices morfométricos. O sítio 2 apresentou árvores de maior porte em relação ao diâmetro e área de copa. O sítio 3 apresentou a maior densidade de árvores (403 árvores ha-1), enquanto nos sítios 1 e 2 foram observadas 362 e 232 árvores ha-1, respectivamente. No sítio 3, a maior parte das árvores apresentou proporção de copa superior a 50% e formal de copa menor que 1, indicando árvores de copas mais estreitas e largas. O diâmetro da árvore apresentou correlação negativa e superior a 70% com o grau de esbeltez. Nos três sítios, o diâmetro apresentou correlação positiva com o diâmetro de copa. Morphometric indices can be used to support the understanding of natural forest dynamics. The aim of this study was to describe and evaluate the morphometric and dendrometric characteristics of Araucaria angustifolia, to understanding of the structure of natural Araucaria Forest. The data were obtained in three counties of Santa Catarina State, considering different altitudes of occurrence of the species. We sampled 247 trees, using the Bitterlich method, and we measured the circumferences at 1.30 m from the ground, total height and crown insertion height and crown radius. The trees interdimensional relationships were described through morphometric indices. Site 2 showed larger trees considering crown area diameter. Site 3 had the highest tree density (403 trees ha-1), while sites 1 and 2 showed 362 and 232 trees ha-1, respectively. At site 3, most trees presented crown ratio greater than 50% and crown fullness ratio lower than 1, indicating trees with narrower and larger crowns. The tree diameter showed a negative correlation, higher than 70% with the degree of slenderness. The diameter presented a positive correlation with the crown diameter in the three sites.
