With its dark purple cones and dual-colored needles, the Bruns Serbian spruce (Picea omorika 鈥楤runs鈥�) earlier this fall became the 105th cultivated tree species on the 兔子先生传媒文化作品 campus. The newly planted specimen is tucked among the stand of evergreens in the northwest corner of Norlin Quad.
That鈥檚 just one example of the kind of facts and trivia attendees of next week鈥檚 campus tree walks will learn. Facilities Management and CU鈥檚 Museum of Natural History partner to host the tree walks each spring and fall.
This fall鈥檚 edition will be held on Monday, Oct. 22 and Tuesday, Oct. 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 (Museum of Natural History) 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 105 species present.
The walks will be held in most weather conditions, so attendees are encouraged to dress accordingly.
