Volunteering on Campus

We have many and varied opportunities for people to help us beautify our campus landscape while spending time in the great outdoors. When you come to volunteer, we’ll ask you to really get your hands dirty--weeding, raking, pruning, planting trees, shrubs, and flowers, cleaning up landscapes, mulching, or replenishing footpaths--and you will feel like you have accomplished something special when you are done. We always come up with fun, active projects that enhance the beauty of campus and engage you with nature and your fellow volunteers.

Champion Trees

The goal of the Prince George’s County Big Tree Program is to identify, measure, and catalog the largest trees of each species in the county. Winners are compared to trees from the Maryland Big Tree Program to find the largest in the state. Trees are scored by: Total Points = circumference (in inches) + height (in feet) + 25% of the average crown spread. Our campus Arboretum currently boasts 16 County Champion Trees, including those pictured below.

Gardens

Our campus is filled with gardens that feature a wide variety of plants, trees, and shrubs. Many of these locations have been designated as pollinator gardens or native plant gardens, although these can be found throughout our landscaping. Search below to find the gardens close to you!
