Narrative
Pecan is native to portions of the south-central Midwest (Carya illinoinensis Native Distribution from Elbert Little's "Atlas of United States Trees") stretching from Iowa along the Mississippi floodplain south to Texas and is well-known for high-quality fall color (yellow) and edible nuts. The species is relatively tolerant to alkaline and slightly acidic soils and can tolerate both extreme drought and severe flood events. However, well-drained soils are preferred. Genetics of this accession represent the extreme northern edge of the species native range with nuts typically reaching maturity in the last week of September into the first week of October in Iowa. Specimens at the collection site in nature measured ~25 inches DBH, with the largest specimen sampled measuring 40.5 inches DBH. Nut measurements (determined by averaging measurements (mm) from 5 randomly selected nuts off a single mother tree) were variable. Averaged measurements (length/width) recorded from 5 mother trees are as follows: tree #4: 23/15 mm, tree #5: 17/12 mm, tree #6: 26/16 mm, tree #7: 24/15 mm, and tree #8: 24/12 mm. Noted observations of progeny from the 2011 collection noted Tree#4 as having strong resistance to the black pecan aphid, Melanocallis caryaefoliae (Davis)(Hemiptera: Aphidadae). Recollection in 2024 found Tree#4 measuring 42.5" DBH dead as the result of major flooding events in 2013, 2014, and 2019 where floods in 2013 persisted for nearly three months. Flood stage for this population of pecan 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 10-12' above ground level where multiple trees of Ames 30882 have been sampled.
