He that plants trees loves others besides himself.
When Nebraska newspaper editor and Secretary of Agriculture J. Sterling Morton founded Arbor Day in 1872, his idea was simple—set aside a special day for tree planting. Today, countries throughout the world celebrate Arbor Day. In the United States, the holiday typically takes place on the last Friday in April, though this date can vary based on a particular state’s climate and a planting season.
Now, 145 years later, Morton’s idea is as important as ever. Not only do trees clean our water and cool our homes; trees also grow fruit, provide natural beauty, and sustain our environment. But people aren’t the only ones who benefit—so do bees, butterflies, birds, and other pollinators.
Declining pollinator populations—particularly bee and Monarch populations—have been a pressing concern for many years, and trees may be one of the solutions to boosting pollinator numbers and helping them to thrive.
In this course, urban forestry professor and researcher Gary Johnson will share how to identify which trees and shrubs attract and fuel all kinds of pollinators, as well as where to position these woody-stemmed perennials so they provide maximum benefits in the landscape.
Participants should be prepared to walk outdoors for a portion of each session.
