It’s looking like the weather will be fine for the third annual Green Tacoma Day.

That’s a good thing, because organizers are predicting 500 people will show up at 15 sites for tours, activities, and chances to work at restoring parks, campuses and natural areas.

The first Green Tacoma Day drew about 100 people to Julia’s Gulch, where they rescued trees from ivy and went to war with blackberries. The event’s grown in size and scope. This year, participants can work, walk or play, learning all the way in a packed schedule from 9 a.m. to noon.

Blueberry Park Volunteers, invite folks to browse the 4,000 blueberry bushes on 20 acres. The Dome District Development Group, First Creek Neighbors and Friends of Julia’s Gulch will offer tours with information on native plants and how a watershed works.

Tacoma Nature Center, Swan Creek and McKinley Park will have activities for children, including an ivy pull contest at the Nature Center.

Worker bees can show up at Garfield Gulch, Go Le Hi Te Wetlands, Lincoln High school, McKinley Park, Meadow Park Golf Course, Oak Tree Park, Pacific Lutheran Unversity, Puget Creek, and Tacoma Community College.

In the afternoon, the city’s community gardeners are inviting visitors to see what’s growing.
