Rochester Museum & Science Center's 900 acre Cumming Nature Center (6472 Gulick Road, Naples) will offer a new exploratory program on trees, beginning this weekend. Focus on Trees is a series of guided walks for all ages with Dave Gotham, director of CNC. Each informative woodland walk will highlight a specific tree species with facts about the many important things we derive from trees, including lumber, medicine, oxygen, heat, paper, wildlife cover, and food.

Walks will take place from 9:30 a.m. to noon, beginning Saturday, July 27, and continuing into the fall. This weekend's program focuses on Plantations, with a hike to six plantations and discussion centered on their potential economic benefits and the drawbacks.

Participation in the hikes is free for RMSC members, with a donation of $3 per person or $10 per family requested from the general public. CNC trails are open 9 a.m.-3:30 p.m., Wednesday-Friday, and 9 a.m.-4:30 p.m. on Saturday and Sunday. Visit rmsc.org or call 374-6160 for more information.
