Metal dendrometer bands are installed on trees to obtain precise estimates of diameter growth. Bands are fixed to astratified random subset of trees (n= 225 - 3,000; varies by site) and are measured one to four times per year using precision digital calipers. In temperate regions, measurements are made at the beginning and end of the growing season. Crown exposure index, crown condition (completeness), and sometimes liana coverage of the crown are also judged on a 5-point scale at every recensus.
