Final collections of bur oak and relatives leaf tissue — NSF Dimensions of Biodiversity

Mira Garner and Leah Samuels (Herbarium and Plant Systematics Lab) collected leaf tissue from their 55th and final site this past week for the NSF-funded Dimensions of Biodiversity oak syngameon study that the Arboretum is leading. They collected 530 specimens this summer representing ten species, covering essentially the entire range of bur oak (the red points on the map below show their collection sites). Great work, Mira and Leah!
