Kentucky coffeetree is a picturesque shade tree that is extremely tolerant to highly alkaline and also slightly acidic soils, tolerant to both extreme drought and flood events, and has no serious insect or disease problems. These traits make G. dioicus a promising candidate among diverse tree genera to replace ash (Fraxinus) trees affected by the emerald ash borer (Agrilus planipennis) or oaks (Quercus) being affected by oak wilt (caused by the fungus Ceratocystis fagacearum) (Schmitz & Carstens 2017). Specimens at the collection site in nature averaged (n=7) 14.50” DBH and 53’ in height (Individual Tree measurements (DBH/Height): #1 = 13"/40', #2 = 15"/50', #3 = 14"/40', #4 = 15"/50', #5 = 13"/30', #6 = 16"/90', and #7 = 15"/70'). Sampling in 2010 estimated more than one hundred genetically distinct trees – the most coffeetrees noted in any single area observed throughout the species native range (Schmitz & Carstens 2018). A return site visit in 2016, estimated that three-quarters of the coffeetrees were dead or in decline after becoming overgrown by hops (Humulus sp.), a result of major flooding events in 2013 and 2014 where floods in 2013 persisted for nearly three months. Flood stage for this population of coffeetrees in the NW ¼ of Sec. 1 resides at 538 MSL (Mean Sea Level) which can be compared against data from the Mississippi River Lock and Dam 17 (Flood Events 2009-2024), where water levels were recorded 14' above ground level where multiple trees of Ames 30493 were sampled. 1831352Ames 30493

Considering that seed production was very poor in 2012, some specimens recorded as non-fruiting (potentially males) may actually be females. The SE 1/4 of Sec. 12 seemed to have a fair amount of G. dioicus regeneration with very small (6-24" tall) seedlings present along with an abundant number of Celtis occidentalis in the area of various sizes. Two very large (20-24" d.b.h. specimens of G. dioicus recently dropped to the ground, most likely the result of strong winds. This area also seems to represent two, distinctly different "clones" of males based on morphological branching structure. The SW 1/4 of Sec. 19 has an abundant population of Tilia americana that were significant in size (20-24" d.b.h. and approximately 70' in height). The largest specimen of G. dioicus found in this area is approximately 90' in height and 40' in width and 35.5" in diameter.1749824Ames 29376
