Oak ecosystems are declining across the Midwest. The Arboretum is undertaking research and restoration initiatives to find ways to combat these declines.
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.
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.
Working with partners from multiple sectors in Latin America to research and protect threatened tree species, and advance tree conservation across the region
