As soon as a typical sight, Missouri’s native chestnut tree, Castanea ozarkensis, offered meals for folks and animals in addition to wooden for furnishings and musical devices. Now, the tree, additionally referred to as the Ozark chinquapin, is unfamiliar to most Missourians.
Within the early 20th century, chestnut blight worn out hundreds of thousands of Castanea ozarkensis. The remaining bushes develop solely to a fraction of their former giant stature and produce few viable seeds.
However there’s hope for this as soon as beloved tree, due to efforts from the Ozark Chinquapin Basis, with help from the Missouri Botanical Backyard, to establish and cross blight-resistant remnant bushes with comparable survivors and plant them within the chinquapin’s historic vary.
What’s the Ozark chinquapin?
Castanea ozarkensis, or the Ozark chinquapin, is a tree native to the Ozark-Ouachita Mountain areas of Missouri, Arkansas and Oklahoma. It can be present in Alabama, Georgia, Mississippi, Japanese, and some others scattered areas within the southeastern US.
Earlier than blight, the tree was as soon as a typical upland forest species, and the drought-tolerant hardwood bushes grew as much as 65 toes tall and a couple of–3 toes in diameter. Now, the bushes now to be 20–30 toes tall. It blooms from Could to June, producing yellowish-white flowers and sprout inexperienced rectangular leaves that flip a shade of yellow within the fall.
The tree produces extremely nutritious, sweet-tasting edible chestnuts.
Chestnuts as a meals supply
Ozark chestnuts are edible uncooked or roasted. They can be utilized in baked items. The chestnuts have been as soon as a meals supply for Native Individuals and early settlers. Indigenous folks used them in steamed corn bread dishes much like tamales that always contained beans and nuts.
Native wildlife, together with squirrels, chipmunks, deer, and birds, loved the candy chestnuts as properly.
Drugs and Music
Ozark folklore archives point out that the Ozark chinquapin had historic medical makes use of, too, together with a tea made out of boiling leaves or nuts to treatment a cough, chilly, or sore throat. The hardy wooden of the chinquapin was used extensively for furnishings and fences attributable to its rot resistance. Wooden was additionally used to create musical devices, together with fiddles and banjoes.

What occurred to the Chinquapin inhabitants?
Cryphonectria parasitica, generally referred to as Chestnut blight, arrived within the U.S. from imported chestnut bushes from Asia within the 1800s. The illness was first recognized in New York in 1904, in line with the Ozark Chinquapin Basis, and reached the Ozark space within the Sixties. Inside a decade, Ozark Hills “have been affected by the lifeless, rot-resistant carcasses of Ozark chinquapin bushes that reached as much as 65 toes excessive”. The blight worn out all however a number of giant mature tree.
Whereas there are nonetheless uncommon giant bushes all through the vary, most chinquapins that survive immediately are small and produce only a few seeds wanted to repopulate the species.
Combating for the long run
The Ozark Chinquapin Basis, or OCF, was based in 2007 with a imaginative and prescient of restoring the native tree again to southern forests and woodlands. Backyard Scientist Matthew Albrecht, who serves as a science advisor for OCF, has partnered on this work in varied methods.
The Backyard’s Middle of Conservation and Sustainable Improvement, or CCSD, helped help the OCF’s blight-testing program to display screen bushes for blight resistance. The Backyard grew dozens of Chinese language and American chestnut seedlings, which served as benchmarks for evaluating blight resistance in Ozark chinquapin bushes and OCF workers contaminated the leaves of all three species with blight to find out which Ozark Chinquapin bushes are extra blight resistant and must be used for OCF’s cross pollination work.
The tree can also be one of many species CCSD will work on in a brand new undertaking, funded by a grant from the Institute of Museum and Library Companies, that can look at adaptive and impartial genetic and phenotypic variation in botanical backyard dwelling collections.
OCF is accumulating seeds from bushes within the wild this autumn for this analysis undertaking. Outcomes from this analysis will assist inform ongoing efforts to revive the species to its indigenous vary.
On the Backyard
The Backyard added two Ozark chinquapin to its dwelling assortment in 2023. That is a part of the Backyard’s conservation horticulture strategy, which focuses on conserving threatened vegetation inside landscapes in botanical gardens.
“This species checks quite a lot of packing containers for our dwelling assortment and the brand new panorama, because it was not but represented on grounds, it’s threatened, it’s a lovely and attention-grabbing tree, and it has a great deal of academic potential,” defined Becky Sucher, Senior Supervisor Dwelling Collections.
She hopes that story of the Ozark chinquapin can inform guests in regards to the penalties of introducing non-native pests and pathogens to our native flora, how pests and pathogens are launched, the biology of an infection, financial and ecological impacts, administration and conservation efforts to manage illness, and extra.
As work continues, it’s potential extra Ozark chinquapin bushes can be added to the Backyard’s panorama, or at Shaw Nature Reserve.
For now, search for the 2 bushes out within the panorama outdoors of the Jack C. Taylor Customer Middle.
