In 2009 and 2011 the students of the Environmental Residential College carried out a service project to remove invasive species and to plant native trees on the steep slope above the Gateway residential halls in the President's Grove on Bucknell University campus.  The ancient oaks in the grove are under threat of invasive species, such as Norway maple (Acer platanoides) and Japanese knotweed (Fallopia japonica).  These invasive plants aggressively compete for light, water and nutrients disturbing the natural ecosystem.  The eastern redbud (Cercis canadensis) and flowering dogwood (Cornus florida) trees planted by the Environmental Residential College are now well established and will continue to thrive if we are diligent in regularly removing invasive species from this site.
