Measuring Stem Growth Rates for Determining Age and Cohort Analysis of a Tropical Evergreen Tree, pp. It is a shade-intolerant species that persists throughout forest succession.
Stands usually regenerate following synchronized dieback of the canopy cohort.
Like most tropical evergreen trees, Metrosideros does not form growth rings, making determination of tree age and stand turnover rates difficult. This study measured the annual stem diameter growth rate for 3 yr in cohorts of six different stem size classes on young volcanic substrates at 1100 m above sea level on the island of Hawai'i. The growth rates were used to predict mean cohort tree age based on mean tree diameter, adjusting for variation in growth rate during the life cycle of the trees. This cohort was undergoing stand dieback, with regeneration of a new cohort, and is assumed to represent the terminal stage of the cohort life cycle. Individual growth rates within cohorts were highly variable.
