Our Efforts
Not only do we control invasives in our natural areas, we work to prevent their spread and help prevent new species from becoming established. We focus on controlling the most damaging plant species, including pale swallow-wort (Cynanchum rossicum), Japanese knotweed (Fallopia japonica), Norway maple (Acer platanoides), common buckthorn (Rhamnus cathartica), and amur honeysuckle (Lonicera maackii).
Hemlock Woolly Adelgid Control
The presence of hemlock woolly adelgid, which has decimated eastern hemlock stands throughout the eastern U.S., poses a significant threat to our natural areas.
Ash Conservation
Learn about what Cornell Botanic Gardens is doing to conserve and return ash to our forests, and how you can help.
Featured Efforts
Ash saplings newly planted on Cornell land are potentially resistant to devastating emerald ash borer insects, making the university the first propagation center in New York state.
Cornell Chronicle—October 20, 2017, Cornell Botanic Gardens received a grant from the New York State Department of Environmental Conservation to continue and expand its work to conserve hemlock trees that are foundational to the university’s campus and natural areas.
Some 50 priority ash trees within campus natural areas were treated with pesticide injections donated by Arborjet.
