Cycling in plants is probably best known for semelparous, strict biennials.
These plants are rosettes one year and flower the second year. The rosette
population is likely to be much larger creating cycling of total population
size for that cohort (e.g. the cohort flowering in even years). Some
populations may have two cohorts but if disturbances that create recruitment
opportunities occur over large areas, then the population may be dominated by a
single cohort and have biennial cycling.
My research group has documented similar patterns for an annual plant (Warea
carteri) with delayed recruitment in an article in Population Ecology (2011,
volume 53, pages 131-142). In this case the biennial cycles gradually dampen
due to some seeds germinating in off-years. The cycling is usually initiated by
fire and subsequent mass recruitment from a persistent soil seed bank.

Perhaps the best example is masting in trees.

The classic examples of populations that cycle, including predator-prey
interactions, and some host-parasite interactions, all involve animals. Are
there similar examples of cycles in plant populations? Certainly lots of
variation in abundance, such as in population size of desert annuals responding
to precipitation, but what about regular (cyclic) variation?
