The Influence of the Atlantic Multidecadal Oscillation on Tupelo Honey Production since AD 1800

Type: Oral Presentation
Track: Dendroclimatology

Content

We reconstructed tupelo honey yield-per-hive from 1800–2010 using tree-ring data from the nectar-source species, Nyssa ogeche. The composite N. ogeche radial growth chronology and honey yield-per-hive were significantly correlated, suggesting optimal growth conditions are coincident with increased nectar production and that tree-ring data can be used to reconstruct crop history. Tupelo honey yield-per-hive has oscillated between multidecadal-length periods of low and high yields during the past 211 years and is associated with the Atlantic Multidecadal Oscillation (AMO). The expansion of the honey record suggests that the current decline is within the natural range of variability prior to record-keeping. Multidecadal-length variations in tupelo honey yield illustrate how naturally occurring climatic cycles affect crop productivity beyond the length of recorded high-quality agriculture records and may offer additional information to better understand interactions between oceanic-atmospheric climate drivers, non-climatic anthropogenic impacts, and yield variability.
