Conservation in Action

Few small ornamental trees offer so many attractive qualities in the landscape as the paperbark maple (Acer griseum).

Biology in the Wild

 
“I was amazed to learn that the Ginkgo biloba tree, which is thousands of years old but extinct in the wild, was saved by Buddhist monks who planted this tree in their monasteries so the species would live on!”
“We thought we would only hear the Latin names of a multitude of obscure plants,” she said, “but instead we heard amazing stories of survival and cooperation in nature.”
 
 
 
These were just two of the observations made by freshman and sophomore students who took one of the free guided tours at the Washington Park Arboretum.
