Oak ecosystems are declining across the Midwest. The Arboretum is undertaking research and restoration initiatives to find ways to combat these declines.
Determining the threat of extinction for tree species globally.
Midwestern forests are a “hot spot” for nitrogen deposition - a pervasive, and perhaps irreparable, anthropogenic global change phenomena. Could this be driving declines in oak regeneration across Chicagoland?
We collected acorns from across the range of Quercus havardii and distributed them to partner gardens to grow, research, and showcase this unique oak to the public.
Preserving wild populations of native, at-risk U.S. trees and increasing the conservation quality of botanical collections through effective conservation planning.
We are using DNA data to better understand the fragmentation and recent history of populations of threatened species especially oaks, ashes and magnolias, in the southeastern and western US.
Linking science to practice to achieve effective conservation of oak diversity
Working with partners from multiple sectors in Latin America to research and protect threatened tree species, and advance tree conservation across the region
Consistent, integrative ecological monitoring is essential to determine the health of the forest and the impacts of management.
A network of coordinated institutions to prevent extinctions and ensure healthy oak populations for the future.
