Why do tropical hardwood trees have small spacing between their annular rings?
In the tropics trees do not stop growing. they grow at a constant speed throughout the seasons because in the tropics it is alsways hot and humid. Tropical trees do not have "annual growth rings" per se, meaning that the rings seens in a cross section are just growth rings (not annual ones). This is in contrast to trees that grow in the temperate zones that have 4 well defined seasons. In these zones the trees do not grow in winter. In the spring, with new growth, the cambium layer of the tree trunk puts out new xylem and phloem cells which form a new "annual ring" over the cells which stopped growing during winter. These are genuine "annual rings" and tropical trees do not have these because they do not experience periods of growth and non-growth.
