On Sunday, Sept. 26 from 1 to-3 p.m., Merryspring Nature Center will host a free family workshop on Tree ID.

Ever wanted to know how to tell the difference between a Sugar Maple and a Norway Maple? Ever wonder what makes a Quaking Aspen quake? Then come to Merryspring’s Tree ID workshop to learn these and other wonderful facts about trees. Participants can also learn how to identify trees by going on a tree scavenger hunt, and learn more about invasive pests that threaten Maine’s forests.

The Tree ID workshop is part of Merryspring’s Nature Explorers series, led by environmental educator Leo Maheu and offered on the fourth Sunday of the month from June through September, which introduces a different nature-based topic each month. A second series, Outdoor Adventures, is offered on the second Sunday of each month from June through September, and focuses on a different family-friendly, outdoor activity each month.

Family programs are offered at no charge. Activities are designed for ages 5-12 but are open to all. All children must be accompanied by an adult. In case of rain, activities will be moved indoors.

Merryspring is a member-supported, non-profit nature education center and park located at the end of Conway Road just off Route 1 by the Hannaford shopping plaza in Camden. For more information, call Merryspring at 236-2239 or visit the Web site at www.merryspring.org.
