In September 2019, Andrew Gapinski, Sean Halloran, and Jared Rubinstein of the Arnold Arboretum hosted Dr. Tao Deng and Dr. Xinfen Gao of the Chinese Academy of Sciences and Dr. Kang Wang of the Beijing Botanical Garden on the very first NACPEC North American plant collection expedition. The six participants, along with Angela Magnan of the US National Arboretum spent three weeks exploring the Appalachian Mountains, collecting in Ohio, Kentucky, Tennessee, Georgia, and North Carolina. They made 100 collections, including from the southernmost population of Populus grandidentata in the country, from the only population of Viburnum bracteatum in Tennessee, and from the rare Buckleya distichophylla—possibly from the same population sampled by Asa Gray in the 19th century.

The team collected seedings, cuttings, and herbarium vouchers that were shared with other NACPEC member institutions around the world. The expedition also included visits with other NACPEC institutions, such as the Dawes Arboretum, the National Arboretum, and the Morris Arboretum.
