Oak ecosystems are declining across the Midwest. The Arboretum is undertaking research and restoration initiatives to find ways to combat these declines.
Saving oaks from extinction through integrated conservation management and global collaborations.
Completing threat assessments for key tree groups to prioritize species for conservation and enable policymakers and conservation practitioners to protect threatened trees.
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?
Linking science to practice to achieve effective conservation of oak diversity
Locating, prioritizing, and proposing amendments to spatial and genetic gaps within ex-situ collections of native U.S. oaks, towards the continued security of each species.
We are using DNA data to further understand the reproductive biology of an under-studied oak, Quercus havardii, which will help inform seed collection strategies and collection management.
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 connectivity and recent history of populations of Quercus havardii, a Western sand dune oak.
We are quantifying the number of plants and seeds needed to best preserve genetic variation of 10 species of threatened trees in botanical gardens, which will be models for future seed collections.
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.
