That’s just one example of the kind of facts and trivia attendees of next week’s campus tree walks will learn. Facilities Management and CU’s Museum of Natural History partner to host the tree walks each spring and fall.
This spring’s edition will be held on Tuesday, May 22 and Wednesday, May 23, beginning at 5 p.m. each day. Led by campus Arboriculture Manager Vince Aquino and retired Outdoor Services Director Alan Nelson, the walks start at the south entry to the Henderson Building and last about two hours. The walks are free and open to the public.
The tours are always slightly different as Aquino and Nelson lead attendees to various spots on Main Campus, discussing the natural and human history of some of the 104 species present.
The walks will be held in most weather conditions, so attendees are encouraged to dress accordingly.
