[[Herbchronology]] is the analysis of annual [[growth rings]] (or simply annual rings) in the secondary root [[xylem]] of [[perennial]] [[herbaceous plants]]. Similar seasonal patterns also occur in [[ice core]]s and in [[varve]]s (layers of [[sediment]] deposition in a lake, river, or sea bed). The deposition pattern in the core will vary for a frozen-over lake versus an ice-free lake, and with the fineness of the sediment. [[Sclerochronology]] is the study of [[algae]] deposits.

Some columnar [[cactus|cacti]] also exhibit similar seasonal patterns in the isotopes of carbon and oxygen in their spines ([[acanthochronology]]). These are used for dating in a manner similar to dendrochronology, and such techniques are used in combination with dendrochronology, to plug gaps and to extend the range of the seasonal data available to archaeologists and [[paleoclimatologist]]s.

A similar technique is used to [[Estimating the age of fish|estimate the age of fish]] stocks through the analysis of growth rings in the [[otolith]] bones.
